oled vs lcd displays in stock

There are plenty of new and confusing terms facing TV shoppers today, but when it comes down to the screen technology itself, there are only two: Nearly every TV sold today is either LCD or OLED.

The biggest between the two is in how they work. With OLED, each pixel provides its own illumination so there"s no separate backlight. With an LCD TV, all of the pixels are illuminated by an LED backlight. That difference leads to all kinds of picture quality effects, some of which favor LCD, but most of which benefit OLED.

LCDs are made by a number of companies across Asia. All current OLED TVs are built by LG Display, though companies like Sony and Vizio buy OLED panels from LG and then use their own electronics and aesthetic design.

So which one is better? Read on for their strengths and weaknesses. In general we"ll be comparing OLED to the best (read: most expensive) LCD has to offer, mainly because there"s no such thing as a cheap OLED TV (yet).

At the other side of light output is black level, or how dark the TV can get. OLED wins here because of its ability to turn off individual pixels completely. It can produce truly perfect black.

The better LCDs have local dimming, where parts of the screen can dim independently of others. This isn"t quite as good as per-pixel control because the black areas still aren"t absolutely black, but it"s better than nothing. The best LCDs have full-array local dimming, which provides even finer control over the contrast of what"s onscreen -- but even they can suffer from "blooming," where a bright area spoils the black of an adjacent dark area.

Here"s where it comes together. Contrast ratio is the difference between the brightest and the darkest a TV can be. OLED is the winner here because it can get extremely bright, plus it can produce absolute black with no blooming. It has the best contrast ratio of any modern display.

One of the main downsides of LCD TVs is a change in picture quality if you sit away from dead center (as in, off to the sides). How much this matters to you certainly depends on your seating arrangement, but also on how much you love your loved ones.

A few LCDs use in-plane switching (IPS) panels, which have better off-axis picture quality than other kinds of LCDs, but don"t look as good as other LCDs straight on (primarily due to a lower contrast ratio).

OLED doesn"t have the off-axis issue LCDs have; its image looks basically the same, even from extreme angles. So if you have a wide seating area, OLED is the better option.

Nearly all current TVs are HDR compatible, but that"s not the entire story. Just because a TV claims HDR compatibility doesn"t mean it can accurately display HDR content. All OLED TVs have the dynamic range to take advantage of HDR, but lower-priced LCDs, especially those without local-dimming backlights, do not. So if you want to see HDR content it all its dynamic, vibrant beauty, go for OLED or an LCD with local dimming.

In our tests comparing the best new OLED and LCD TVs with HDR games and movies, OLED usually looks better. Its superior contrast and lack of blooming win the day despite LCD"s brightness advantage. In other words LCD TVs can get brighter, especially in full-screen bright scenes and HDR highlights, but none of them can control that illumination as precisely as an OLED TV.

OLED"s energy consumption is directly related to screen brightness. The brighter the screen, the more power it draws. It even varies with content. A dark movie will require less power than a hockey game or ski competition.

The energy consumption of LCD varies depending on the backlight setting. The lower the backlight, the lower the power consumption. A basic LED LCD with its backlight set low will draw less power than OLED.

LG has said their OLED TVs have a lifespan of 100,000 hours to half brightness, a figure that"s similar to LED LCDs. Generally speaking, all modern TVs are quite reliable.

Does that mean your new LCD or OLED will last for several decades like your parent"s last CRT (like the one pictured). Probably not, but then, why would you want it to? A 42-inch flat panel cost $14,000 in the late 90"s, and now a 65-inch TV with more than 16x the resolution and a million times better contrast ratio costs $1,400. Which is to say, by the time you"ll want/need to replace it, there will be something even better than what"s available now, for less money.

OLED TVs are available in sizes from 48 to 88 inches, but LCD TVs come in smaller and larger sizes than that -- with many more choices in between -- so LCD wins. At the high end of the size scale, however, the biggest "TVs" don"t use either technology.

If you want something even brighter, and don"t mind spending a literal fortune to get it, Samsung, Sony, and LG all sell direct-view LED displays. In most cases these are

You can get 4K resolution, 50-inch LCDs for around $400 -- or half that on sale. It"s going to be a long time before OLEDs are that price, but they have come down considerably.

LCD dominates the market because it"s cheap to manufacture and delivers good enough picture quality for just about everybody. But according to reviews at CNET and elsewhere, OLED wins for overall picture quality, largely due to the incredible contrast ratio. The price difference isn"t as severe as it used to be, and in the mid- to high-end of the market, there are lots of options.

For all the new technologies that have come our way in recent times, it’s worth taking a minute to consider an old battle going on between two display types. Two display types that can be found across monitors, TVs, mobile phones, cameras and pretty much any other device that has a screen.

In one corner is LED (light-emitting diode). It’s the most common type of display on the market, however, it might be unfamiliar because there’s slight labelling confusion with LCD (liquid crystal display).

For display purposes the two are the same, and if you see a TV or smartphone that states it has an ‘LED’ screen, it’s an LCD. The LED part just refers to the lighting source, not the display itself.

In a nutshell, LED LCD screens use a backlight to illuminate their pixels, while OLED’s pixels produce their own light. You might hear OLED’s pixels called ‘self-emissive’, while LCD tech is ‘transmissive’.

The light of an OLED display can be controlled on a pixel-by-pixel basis. This sort of dexterity isn’t possible with an LED LCD – but there are drawbacks to this approach, which we’ll come to later.

In cheaper TVs and LCD-screen phones, LED LCD displays tend to use ‘edge lighting’, where LEDs sit to the side of the display, not behind it. The light from these LEDs is fired through a matrix that feeds it through the red, green and blue pixels and into our eyes.

LED LCD screens can go brighter than OLED. That’s a big deal in the TV world, but even more so for smartphones, which are often used outdoors and in bright sunlight.

Brightness is generally measured as ‘nits’ – roughly the light of a candle per square metre. Brightness is important when viewing content in ambient light or sunlight, but also for high dynamic range video. This applies more to TVs, but phones boast credible video performance, and so it matters in that market too. The higher the level of brightness, the greater the visual impact.

Take an LCD screen into a darkened room and you may notice that parts of a purely black image aren’t black, because you can still see the backlighting (or edge lighting) showing through.

You’ll often see a contrast ratio quoted in a product’s specification, particularly when it comes to TVs and monitors. This tells you how much brighter a display’s whites are compared to its blacks. A decent LCD screen might have a contrast ratio of 1,000:1, which means the whites are a thousand times brighter than the blacks.

Contrast on an OLED display is far higher. When an OLED screen goes black, its pixels produce no light whatsoever. That means an infinite contrast ratio, although how great it looks will depend on how bright the screen can go. In general, OLED screens are best suited for use in darker rooms, and this is certainly the case where TVs are concerned.

OLED panels enjoy excellent viewing angles, primarily because the technology is so thin, and the pixels are so close to the surface. You can walk around an OLED TV or spread out in different spots in your living room, and you won’t lose out on contrast. For phones, viewing angles are extra important because you don’t tend to hold your hand perfectly parallel to your face.

Viewing angles are generally worse in LCDs, but this varies hugely depending on the display technology used. And there are lots of different kinds of LCD panel.

Thankfully, a lot of LCD devices use IPS panels these days. This stands for ‘in-plane switching’ and it generally provides better colour performance and dramatically improved viewing angles.

IPS is used in most smartphones and tablets, plenty of computer monitors and lots of TVs. It’s important to note that IPS and LED LCD aren’t mutually exclusive; it’s just another bit of jargon to tack on. Beware of the marketing blurb and head straight to the spec sheet.

The latest LCD screens can produce fantastic natural-looking colours. However, as is the case with viewing angles, it depends on the specific technology used.

OLED’s colours have fewer issues with pop and vibrancy, but early OLED TVs and phones had problems reining in colours and keeping them realistic. These days, the situation is better, Panasonic’s flagship OLEDs are used in the grading of Hollywood films.

Where OLED struggles is in colour volume. That is, bright scenes may challenge an OLED panel’s ability to maintain levels of colour saturation. It’s a weakness that LCD-favouring manufacturers enjoy pointing out.

Both have been the subject of further advancements in recent years. For LCD there’s Quantum Dot and Mini LED. The former uses a quantum-dot screen with blue LEDs rather than white LEDs and ‘nanocrystals’ of various sizes to convert light into different colours by altering its wavelength. Several TV manufacturers have jumped onboard Quantum Dot technology, but the most popular has been Samsung’s QLED branded TVs.

Mini LED is another derivation of LED LCD panels, employing smaller-sized LEDs that can emit more light than standard versions, increasing brightness output of the TV. And as they are smaller, more can be fitted into a screen, leading to greater control over brightness and contrast. This type of TV is becoming more popular, though in the UK and Europe it’s still relatively expensive. You can read more about Mini LED and its advantages in our explainer.

OLED, meanwhile, hasn’t stood still either. LG is the biggest manufacturer of large-sized OLED panels and has produced panels branded as evo OLED that are brighter than older versions. It uses a different material for its blue OLED material layer within the panel (deuterium), which can last for longer and can have more electrical current passed through it, increasing the brightness of the screen, and elevating the colour volume (range of colours it can display).

Another development is the eagerly anticipated QD-OLED. This display technology merges Quantum Dot backlights with an OLED panel, increasing the brightness, colour accuracy and volume, while retaining OLED’s perfect blacks, infinite contrast and potentially even wider viewing angles, so viewers can spread out anywhere in a room and see pretty much the same image. Samsung and Sonyare the two companies launching QD-OLED TVs in 2022.

And for smartphones there’s been a move towards AMOLED (Active-Matrix Organic Light Emitting Diode) screens for Android screens, while Apple has moved towards OLED for its smartphones and tried Mini LED with its iPad Pro. Technologies are consistently evolving with Superand Dynamic AMOLED versions available, more performance is being eked out.

While LED LCD has been around for much longer and is cheaper to make, manufacturers are beginning to move away from it, at least in the sense of the ‘standard’ LCD LED displays, opting to explore the likes of Mini LED and Quantum Dot variations.

OLED has gained momentum and become cheaper, with prices dipping well below the £1000 price point. OLED is much better than LED LCD at handling darkness and lighting precision, and offers much wider viewing angles, which is great for when large groups of people are watching TV. Refresh rates and motion processing are also better with OLED though there is the spectre of image retention.

If you’re dealing with a limited budget, whether you’re buying a phone, a monitor, a laptop or a TV, you’ll almost certainly end up with an LCD-based screen. OLED, meanwhile, incurs more of a premium but is getting cheaper, appearing in handheld gaming devices, laptops, some of the best smartphones as well as TVs

Which is better? Even if you eliminate money from the equation, it really comes down to personal taste. Neither OLED nor LCD LED is perfect. Some extol OLED’s skill in handling darkness, and its lighting precision. Others prefer LCD’s ability to go brighter and maintain colours at bright levels.

How do you decide? Stop reading this and go to a shop to check it out for yourself. While a shop floor isn’t the best environment in which to evaluate ultimate picture quality, it will at least provide an opportunity for you to realise your priorities. Whether you choose to side with LCD or OLED, you can take comfort in the fact that both technologies have matured considerably, making this is a safe time to invest.

OLED displays have higher contrast ratios (1 million : 1 static compared with 1,000 : 1 for LCD screens), deeper blacks and lower power consumption compared with LCD displays. They also have greater color accuracy. However, they are more expensive, and blue OLEDs have a shorter lifetime.

OLED displays offer a much better viewing angle. In contrast, viewing angle is limited with LCD displays. And even inside the supported viewing angle, the quality of the picture on an LCD screen is not consistent; it varies in brightness, contrast, saturation and hue by variations in posture of the viewer.

There are no geographical constraints with OLED screens. LCD screens, on the other hand, lose contrast in high temperature environments, and lose brightness and speed in low temperature environments.

Blue OLEDs degrade more rapidly than the materials that produce other colors. Because of this, the manufacturers of these displays often compensate by calibrating the colors in a way that oversaturates the them and adds a bluish tint to the screen.

With current technology, OLED displays use more energy than backlit LCDs when displaying light colors. While OLED displays have deeper blacks compared with backlit LCD displays, they have dimmer whites.

LCDs use liquid crystals that twist and untwist in response to an electric charge and are lit by a backlight. When a current runs through them, they untwist to let through a specific amount of light. They are then paired with color filters to create the display.

AMOLED (Active-Matrix Organic Light-Emitting Diode) is a different form of OLED used in some mobile phones, media players and digital cameras. It offers higher refresh rates with OLEDs and consume a lot less power, making them good for portable electronics. However, they are difficult to view in direct sunlight. Products with AMOLED screens include Galaxy Nexus, Galaxy S II, HTC Legend and PlayStation Vita.

Chances are, the screen that you"re reading this article on is either an LED, OLED, or an LCD display. These are just three of the many display types out there in the wild. On the surface, they all seem the same. But deep down, they couldn"t be more different.

So, when it comes to OLED vs. LCD—or OLED vs. LED—what are the differences? Here"s a look at these three display technologies, what makes them different, and which one is the best.

LCD stands for "liquid crystal display". The early roots of LCD displays stretch back to 1888 when German scientist, Friedrich Reinitzer, discovered an odd substance. It was a liquid that had the molecular structure of a solid. It was later named "liquid crystal."  After decades of study, someone eventually saw the potential for this strange substance to be used for displays.

The first LCD displays to be used on consumer devices were on digital clocks back in 1968. The technology developed over the following years, being put into numerous other devices.

LCD display panels are divided into layers. The backmost layer is a light source. This is a translucent sheet that disperses light from bulbs at the bottom of the display.

OLED stands for "organic light emitting diode." During the 1970s, scientists were experimented with organic materials that can emit light. In 1987, scientists at Eastman Kodak developed an OLED display that consumed a low amount of energy. And in 2007, Sony unveiled the world"s first OLED television: the Sony XEL-1.

On the other side of the OLED, the electrons flow from the cathode. The electrons then flow to the emissive layer, where they meet the holes. Since the electrons are sent through a voltage, they are "excited", meaning that they have an excess of energy.

When they meet the electron holes, they have to lose that excess energy in order to relax to the ground state for that atom. They release that energy in the form of photos (light particles). From there, the light travels through the red, blue, and green sub-pixels, just like with an LCD display.

LED displays are virtually indistinguishable from LCD displays. The only difference is in how the two types of displays get their light. Instead of using a translucent sheet, LED displays use individually LEDs. There are three primary arrangements of LEDs in the displays.

Full array LED displays have the LEDs arranged evenly throughout the display. This is the preferred arrangement on higher-end TVs. There are a lot of LEDs behind the panel, which means that local dimming is possible.

The direct-lit arrangement can appear to be similar to full array, but there are some differences. With the direct-lit arrangement, the LEDs are also dispersed evenly throughout the panel, but there are far less of them. Because of this, direct-lit displays can not do local dimming. This arrangement is present on lower-end devices.

A display is usually judged by its ability to create vibrant colors. This is an area where OLEDs come out on top. Compared to OLED displays, LCD displays often appear washed out and not as saturated. This is why OLED displays are becoming more popular in the smartphone market.

OLED displays can also produce images with higher contrast than the other two technologies. Since all of the OLEDs on the panel can be turned on and off individually, darker areas of the display can go as dark as they need to.

Full array LED displays come in right behind OLED displays because, like in the case of OLED displays, the LEDs in an LED display can be controlled individually. Full array LED displays use a method called "local dimming", a technique of shutting off LEDs completely in areas that are darker.

LCD displays come in last place because in order for any pixels to be visible, the entire back panel has to be lit. This means that completely black areas are impossible to achieve.

In terms of price, LCD displays are typically cheaper. High definition LCD displays can run you no more than a few hundred dollars. Since LED displays offer better contrast over LCD, you can expect there to be an added price premium.

When it comes to power consumption, OLED scores a win. Since the OLEDs are powered individually, the display only gives power to the ones that need it. Pixels can be turn off completely when there are blacks in the picture.

Full array LED displays come in second place because of the local dimming functionality. Certain LEDs can be completely turned off when the scene calls for blacks. Even though they have this feature, more energy is consumed per LED because the light has to pass through all of the layers of the LCD before reaching the viewers" eyes.

LCDs are the least power efficient. Regardless of the presence of blacks in the scene, the entire panel needs to be lit. This means that the light source is shining at 100% the entire time.

Each display technology has its benefits and its drawbacks. LCD displays are for people who want to save more money, while LED displays are for people who would like to spend more for a bit more contrast in their picture. You"ll spend more on the TV, but it will have a less significant impact on your electricity bill.

OLED displays are for those who want the best of all worlds. They produce the best contrast with the most vivid colors. You will be paying the most for the actual device, but the more power efficient display technology will help even out some of that cost.

Competition and innovation are hallmarks of the consumer electronics market which has experienced practically uninterrupted growth for decades. Many consumers own a range of electronic devices (laptop, smartphone, tablet, TV, etc.), each of which is available in a plethora of options: brands; grades, formats; technologies. This technological array is further complicated by marketing terms that try to differentiate between competing products. Acronyms like OLED and LCD are rife in the electronics sector, but what is the actual difference between the two?

The inordinate popularity of smart consumer devices continues to drive growth in the global display market, currently valued in the region of $135 billion. Screens based on LEDs (light-emitting diodes) used to be the industry-standard, but trends towards device miniaturization, portability, improved efficiency, and greater picture quality gradually fuelled OLED (organic light-emitting diode) panels. Over the next few years, the OLED market is expected to expand by a CAGR (compound annual growth rate) of 14.27%.

Currently, OLED televisions outperform traditional LED products on several fronts. They come in a versatile range of formats: panels as large as 88-inches satisfy the demands of premium TV displays; while smaller AMOLED (active-matrix OLED) screens set the benchmark of picture quality in the smartphone industry. Foldable OLED devices have finally begun to enter the consumer electronics market too, fulfilling a long-standing promise from proponents of the technology.

Traditional LED TVs are based on liquid crystal display (LCD) screen technology; a tried-and-tested panel structure. On an LCD screen, images are produced by a thin layer of liquid crystal solution overlaid on a transistor grid which uses small electrical charges to set the individual crystals to an open/closed state. This produces a pattern of light and dark pixels, but the light itself is produced by a bank of LEDs arranged at the edges of the screen or in a backlit array.

The best possible picture on LCD screens is produced using a full-array LED backlight with local-dimming which yields the widest possible contrast. However, LCDs comprise multiple sequential layers within the panel (color filters, polarizers, etc.) which are necessary for producing fully-saturated images but may inhibit picture uniformity and viewing angles. This also makes LED TVs thicker and heavier, rendering them undesirable for applications where reduction of thickness or weight is important.

OLEDs circumvent each of these issues by eschewing a backlight in favor of a self-emissive panel of organic carbon-based material. This allows each subpixel onscreen to be controlled independently. Alongside greater dynamic ranges and energy efficiency, the unique characteristics of OLED panels allow for significantly fewer layers in the screen matrix. Consequently, OLED TVs are typically thinner and lighter in weight than conventional LCDs, but cost significantly more to produce than LCD displays.

OLED vs. IPS LCD is a topic that comes up whenever consumers upgrade to a newer TV or a smartphone. Should you buy a TV that uses an IPS LCD display or should you pick up a TV with an OLED screen? Well, the answer isn’t so straightforward because they both have their advantages and disadvantages. In this article, we will explain how these screen technologies work and which one you should opt for while buying a TV.

IPS LCD (In-Plane Switching Liquid Crystal Display) and OLED (Organic Light-Emitting Diode) are the two most commonly used screen technologies. Older technologies, such as TN (Twisted Nematic) and PLS (Plane-to-Line Switching) displays, have almost disappeared (except in the world of PC monitors and budget laptops) because IPS LCD and OLED are clearly better in almost all aspects. Other technologies such as Mini-LED, MicroLED, and QNED technologies are extremely new and they won’t become mainstream for a few years.

So, when you are finally deciding which TV to buy, the real battle is between OLED and IPS LCD. So where do these stand? Which is better for you? Which one should you pick for your new home theatre? Read on for more information on the OLED vs IPS LCD battle.

IPS LCD displays are perhaps the most common display type days, especially in TVs and laptops. Laptops, entry-level and mid-range smartphones, and most TVs use LCD displays. So, how do IPS displays work? IPS displays use an array of LCD pixels that shift colour as required. However, they don’t emit light on their own. That’s the reason they need a backlight made up of LEDs (Light-Emitting Diodes). The backlight can be arranged in various layouts: towards the edges, spread across the whole display, or separated into different sections.

IPS screens display the black colour by changing the alignment of LCDs so that pixels block the transmission of light, but some light still gets through. That’s the reason IPS LCD displays can’t display true deep black colour. Instead, they display dark grey and there is some ‘backlight bleed’.

OLED displays have traditionally been restricted to high-end devices. Even today, only high-end TVs and laptops feature OLED displays. In the world of smartphones, though, OLED technology has been democratised and even mid-range smartphones these days use OLED displays with high brightness and high refresh rates.

In a nutshell, OLED displays don’t use separate backlight sources. Instead, every pixel can reproduce its own light (also known as self-emissive displays). So, there’s no need for an additional backlight and each pixel can be turned on or off as needed. Since there is no need for a separate backlight plane, OLED displays are much thinner than LCD displays. They also offer a much better contrast ratio and viewing angles. However, the organic material used in OLED pixels tends to “burn” over the years that results in ghosting. Moreover, they can’t be as bright as LCD, Mini-LED, or Micro-LED displays.

We have given you a brief overview of IPS and OLED technologies. But which one is better? And which of these will be right for you? Here’s a list of pros and cons to help you in your purchase decision, where it is for smartphones or TVs.

OLEDs have a quicker response time: OLEDs individually-lit pixels can switch on/off or change colour faster. This makes for lower ghosting during fast-and-frenetic action scenes or while playing games. Ghosting refers to when the image on the screen seems to be following itself around or is blurry at the edges.

OLED TVs are slimmer and flexible: As we mentioned earlier, OLED displays don’t need a bulky backlight plane, so OLED TVs are really slim. The next wave of display technologies – foldable and rollable displays – will also be powered by OLED.

IPS LCD TVs offer higher brightness: IPS LCD TVs use a powerful backlight which also lets them get much brighter than their OLED counterparts. This can make for better HDR and even offer a better viewing experience if your TV room gets a lot of sunlight.

IPS TVs suffer from backlight bleed and blooming: This is less of an issue with high-end IPS TVs, but some cheaper models may suffer from glow (bright, greyish areas near the corners of the screen) or backlight bleed (patches or leaks of light, usually around the edges).

OLED TVs can suffer burn-in: OLED displays are at risk of burn-in, a condition in which a static image left on for too long can get permanently ‘burned’ onto the display and may appear like a ghostly dark patch.

OLEDs may get dimmer with age: OLEDs use organic substances which tend to decay over time. So, OLED displays lose brightness with age. It is quite slow and modern OLED TVs are not as affected by this as older OLED TVs, and this really shouldn’t be an issue, but you need to be aware of this.

IPS TVs are much cheaper: OLED is a relatively newer technology and is more expensive to manufacture. Currently, very few companies make OLED display panels. LG Display makes most of the OLED panels found on OLED TVs, while Samsung Display, CSOT, LG Display, and BOE make OLED screens for smartphones and smaller products. Most manufacturers also tend to restrict OLED tech to their largest, most feature-packed range, fueling the perception of OLED being expensive.

OLED displays have several advantages over LCDs, including superior contrast, thinner profiles, and faster image refresh rates. Plus, they consume less power, and their production is more environmentally friendly than LCDs’.

However, there are tradeoffs. OLED displays are more susceptible to image “burn-in” after prolonged use, and they tend to burn out quicker, too. Their relatively short lifespans are tied to image brightness.

These concessions don’t always make sense for commercial applications, though commercial OLEDs are manufactured with these limitations in mind. For example, modern OLED signage displays protect against burn-in with self-healing technology. Though, as you might expect, their price point is much higher than their LCD alternatives’.

You may be wondering about some other terms we haven’t discussed yet, such as 4K, HiDPI, and Retina display. These describe screen resolutions, and while the subject of resolution could warrant an entire article, there are a few things you should know when selecting (or being sold) displays for your project.

SD is easy to spot because it appears as that 4:3 (almost) squared image on older TVs instead of the widescreen, rectangular shape of modern displays. When you’re watching TV and you see an old show come on with black bars on each side, it’s because the show was produced in SD.

1080i refers to a 1920 x 1080 resolution on a display that creates images by illuminating rows of pixels in an alternating fashion (_interlaced _scan). If a 1080 display lights pixels progressively from top to bottom, the resolution would be called 1080p (progressive scan). The same goes for 720i and 720p displays, which specify a 1280 x 720 resolution with interlaced or progressive scan.

4K indicates a resolution with approximately 4,000 horizontal pixels or approximately four times the pixel count of a 1080p HDTV. 4K displays have at least 8 million active pixels, though the term is not as exact as 1080p. 4K has picked up steam as a marketable buzzword, and 8K displays have emerged as well.

You may also see the term UHD or Ultra High Definition used to describe similar resolutions to 4K. In fact, many consumer displays that would be more accurately described as UHD or 2160p are marketed as 4K. There are some technical differences between 4K and UHD, but they aren’t differences you’d be likely to notice.

DPI (dots per inch) and PPI (pixels per inch) are measures of density that represent the number of pixels per inch of screen. HiDPI is a term used for displays with very high pixel density—usually at least 200 DPI. High-density displays came on our radar with iPhones. Since then, tablets, notebooks, and other HiDPI personal devices have followed.

Today, smartphones have DPIs climbing into the 500s, while an 8K TV might have a PPI of only 117. The reason for this disparity is perspective: the closer the viewer is to the screen, the higher DPI you’ll need for a crisp, seamless image. Though, the opposite is also true. You might not need to splurge on those 8K displays if the viewing area is far away. Most scoreboards and video walls have lower resolutions than a 4K TV—and much lower DPI.

“Retina display” is a proprietary term used by Apple. It refers to displays with a pixel density so high that the human eye cannot perceive the pixels. Apple introduced the term with the iPhone 4, which had 326 DPI. Steve Jobs qualified the screen as having imperceptible pixels at a distance of 12 inches.

Since then, Retina displays have lacked a concrete definition, though they tend to have more than 300 DPI for phones and sometimes less for tablets—the justification being that people tend to hold tablets further away than their phones.

Consumer TVs are not built with these issues in mind. Their chassis are not as sturdy, and their components do not last as long as commercial displays’. Further, consumer TV designs are updated frequently, so you might have a hard time finding a replacement that matches the building’s other displays when the need arises.

Lastly, consumer displays may lack external control functionality. If your facility has multiple displays, you shouldn’t need someone to walk around with a TV remote to turn them on every day. Commercial displays come with standard control ports, so they can be tied into several types of control systems, enabling touchpanel control, scheduled operation, and more. An AV consultant can ensure you get the models you need for seamless integration.

When buying TVs for your commercial project, it’s best to understand your needs clearly and avoid getting distracted by buzzwords and tech hype. The battle between LCD and OLED technology is ongoing as manufacturers work to improve the image quality of LCDs and make OLEDs more durable and affordable.

If you’re designing a display application or deciding what type of TV to get, you’ll probably have to choose between an OLED or LCD as your display type.

LCDs utilize liquid crystals that produce an image when light is passed through the display. OLED displays generate images by applying electricity to organic materials inside the display.OLED and LCD Main Difference:

graphics and images visible. This is the reason you’re still able to see light coming through on images that are meant to be dark on an LCD monitor, display, or television.

OLEDs by comparison, deliver a drastically higher contrast by dynamically managing their individual pixels. When an image on an OLED display uses the color black, the pixel shuts off completely and renders a much higher contrast than that of LCDs.OLED vs LCD - Who is better at contrast?

Having a high brightness level is important if your display is going to be used in direct sunlight or somewhere with high ambient brightness. The display"s brightness level isn"t as important if it’s going to be used indoors or in a low light setting.OLED vs LCD - Who is better at Brightness?

This means the display is much thinner than LCD displays and their pixels are much closer to the surface of the display, giving them an inherently wider viewing angle.

You’ll often notice images becoming distorted or losing their colors when tilting an LCD or when you view it from different angles. However, many LCDs now include technology to compensate for this – specifically In-Plane Switching (IPS).

LCDs with IPS are significantly brighter than standard LCDs and offer viewing angles that are on-par with OLEDs.OLED vs LCD - Who is better at Viewing Angles?

LCDs have been on the market much longer than OLEDs, so there is more data to support their longevity. On average LCDs have proven to perform for around 60,000 hours (2,500) days of operation.

With most LCDs you can expect about 7 years of consistent performance. Some dimming of the backlight has been observed but it is not significant to the quality of the display.

OLEDs are a newer technology in the display market, which makes them harder to fully review. Not only does OLED technology continue to improve at a rapid pace, but there also hasn’t been enough time to thoroughly observe their performance.

You must also consider OLED’s vulnerability to image burn-in. The organic material in these displays can leave a permanent afterimage on the display if a static image is displayed for too long.

So depending on how your OLED is used, this can greatly affect its lifespan. An OLED being used to show static images for long periods of time will not have the same longevity as one displaying dynamic, constantly moving images.OLED vs LCD - Which one last longer?

There is not yet a clear winner when it comes to lifespans between LCD and OLED displays. Each have their advantages depending on their use-cases. It’s a tie!

For a display application requiring the best colors, contrast, and viewing angles – especially for small and lightweight wearable devices – we would suggest an OLED display.

The OLED vs LED monitor debate is real. These competing flat-panel display technologies both have unique qualities, and some potential drawbacks. How to choose which one will suit your needs? While OLED seems like the best bet for all, you might first want to get a clear idea of what you’re going to use the monitor for.

If you researchcomputer monitor technology, or explore the monitors currently available on the market, the OLED vs LED monitor question will pop up sooner than later.

Despite sounding similar, OLED and LED monitors utilize fundamentally different technology to emit light so users can see images on their screen. Both OLED and LED technology have their plus points, as well as their potential drawbacks, so it’s important to get to grips with what each of the two technologies has to offer, along with the situations where one may be more desirable than the other.

This read will provide an in-depth exploration of OLED vs LED monitor technology, outlining how they work, the ways in which OLED and LED monitors differ from one another, and more. We will also provide information on who can benefit the most from each technology and why.

One of the more potentially confusing aspects of monitor technology involves understanding the terminology surroundingLED and LCD displays. While these sound like competing technologies, they’re not, but this is a common misunderstanding. LED refers to the backlighting of the display, while LCD refers to the diodes that produce light on their own. All LED monitors also utilize LCD displays and LED backlighting, which is why they are sometimes described as LED/LCD.

LED does have some potential advantages over OLED. For instance, it can be less prone to issues like screen burn or image retention, where a display continues to show artifacts of a previous image. The backlighting means LED screens are capable of being brighter than OLED screens, and LED monitors are also generally more affordable too. Although LED contrast is weaker than with OLED, mini-LED is a relatively new technology, which helps to bridge this gap.

It’s worth taking the time to understand precisely what OLED monitor technology is and how it works. OLED stands for organic light-emitting diode. The main way in which OLED technology differs from what you would find in a more conventional LED/LCD monitor is that each pixel can autonomously emit light. This is because all pixels are linked to the electroluminescent layer, or the emission of light.

A conventional LED monitor uses light-emitting diodes to emit light when a current runs through it. This then provides the backlight for a liquid-crystal display (LCD) screen and lights up the individual pixels, providing the image that a user sees. By contrast, with OLED technology, the pixels are not backlit. Instead, each individual pixel is able to turn on or off, meaning the display can be controlled down to the individual pixel.

This fundamental difference in technology can also describe OLED as being’emissive’, while LED/LCD technology is instead described as ‘transmissive’. Therefore, despite the two names sounding similar, OLED and LED technology work in completely different ways.

With a basic understanding of what OLED monitor technology is, let’s explore some of its most prominent benefits and learn how an OLED monitor might be a better bet than an LED/LCD display for both work and home use.

One of the most noticeable differences when working with an OLED display — instead of an LED display — is the stark appearance of the color black. As an OLED monitor lights individual pixels, rather than relying on a backlight, these pixels can be turned off entirely, and this produces a pure black color and a higher contrast with white.

Despite recent improvements to LED/LCD displays, generally, OLED monitors offer superior viewing angles. This means that the display will not be distorted or negatively impacted by the angle you view it from. This is a huge change because with some LED monitors you have to sit directly in front of them to see a clear and accurate picture.

With OLED monitors, the absence of backlighting and the thinness of the display panels help to ensure that the picture looks clear and accurate from different angles. Improvements to viewing angles can be especially beneficial if you are going to be using adual monitor setupfor work, as you will likely need to position yourself between both screens.

Another significant benefit associated with OLED monitors — often overlooked before the purchase — is their physical properties. Theinternal components of OLEDmonitors and televisions are made of plastic, organic layers which are thinner and lighter than their LED/LCD crystalline counterparts.

The lightweight nature of OLED technology means that an OLED monitor is likely to weigh less than an equivalent-sized LED monitor, making it easier to transport, carry, and mount. At the same time, the materials used within OLED monitors are also more flexible, and this may mean the monitors are less likely to suffer lasting damage while in transit. Given this upgraded physical properties, it’s not surprising to see that OLED is becoming increasingly popular onportable monitors. And the greater color performances make these models perfect for all photographs and video maker that need to proof their shots on field

Another benefit associated with OLED’s ability to completely dim pixels is the lower levels of blue light emitted by these monitors. In some cases, the reduction in blue light can result in half as much blue light being emitted when compared to LED/LCD panels. In short, this means OLED monitors are better for your eyes.

As OLED monitors allow pixels to be controlled on an individual level, this means that individual pixels can be turned off completely, leading to reduced power consumption when compared to LED monitors with high brightness settings. This can be especially advantageous in settings like offices and schools, where a number of monitors may be needed.

OLED technology is also more environmentally friendly at production level, and this is primarily because it does not utilize the greenhouse gas, nitrogen trifluoride.

Another major plus point of OLED technology is its faster response time thanks to low input lag. In other words, with LED/LCD technology there’s less delay between you performing an action using your mouse or keyboard and that same action presenting itself on the screen.

When considering the need for fast response time, it becomes evident how integral it is especially in reducing input lag and motion blur. In general, LED monitors are more prone to these problems than OLED monitors.

A comparison between an OLED vs LED monitor would not be complete without learning about other monitor panel types that exist. Here’s what they are, how they work, and what they have to offer.

One potential downside to IPS panels, when compared to OLED and Twisted nemantic (TN) panels, is the slower response times. This is unlikely to be an issue with most ways the monitors are used, but if ultra-fast input response times are needed, the two other options mentioned above are likely to be better choices.

Twisted nemantic (TN) panels are the oldest LED/LCD technology and they have some significant disadvantages. For instance, viewing angles are extremely limited, meaning that unless you are directly in front of your monitor, the image may look distorted or incomplete.

Their contrast ratios are also superior to TN panels, although nowadays they do not meet the high contrast ratio levels produced by OLED monitors. Additionally, while VA panels are better than TN technology in most regards, they are more expensive and have slower response times, which may make TN panels a preferred choice for consumers.

Organic light-emitting diode (OLED) screens are the only screens in this comparison that do not use backlights. Instead, the pixels on the display panel can be illuminated or switched off on an individual basis, resulting in monitors that deliverexcellent picture quality. OLED displays are also energy efficient and thin, allowing for great viewing angles.

The incredible color accuracy — especially in terms of presenting pure blacks — can be extremely valuable for all kinds of users. The main disadvantage of OLED technology, however, from a consumer perspective, is the price, as an OLED monitor is likely to be more expensive than an LED/LCD monitor of a similar size and build.

Equipped with an understanding of how OLED and LED monitor technology works, and the plus points associated with different panels types, let’s explore which type will match user needs in different situations. Here are some suggestions for several common computer monitor uses.

If you are working in a field like photography, graphic design, or content creation where color accuracy really matters, anOLED monitoris likely to be the best option available. As we’ve mentioned before the individual illumination of pixels can deliver greater contrast and color accuracy, so crucial to visual artworks.

Controlling the illumination of pixels on an individual level can help to avoid some of the problems caused by LED/LCD technology, such as the ‘halo’ effect appearing around images or text. The superior viewing angles available with OLED monitor technology also open the possibility of a dual monitor setup. And as OLED monitors now also come in portable format, they can even follow creatives on the field for maximum accuracy while shooting.

For casual and home use, it’s likely that either IPS or VA panels will be the best all-round option, especially when factoring in price and performance. IPS display panels are capable of the kind of color accuracy and viewing angles that deliver a positive user experience. VA panels have slow response times, so may not be ideal for gaming, but they offer good color production and contrast ratios without costing the same as an OLED computer monitor typically will.

Work-based usage can be harder to provide clear advice for, because it will depend on the nature of the work. Generally, IPS can be considered a good all-rounder, although VA panels are also well-suited to simple office work. If the work involves designs, relies on color accuracy, though, or would benefit from lower power consumption, OLED monitors may be the superior choice, but this needs to be balanced against the higher price point.

The OLED vs LED monitor comparison focuses on two competing forms of flat-panel display technology. In many ways, OLED has emerged as the gold standard of display technology, combining energy efficiency, superior viewing angles, and excellent color accuracy, even if the more expensive pricing is a potential downside.

Nevertheless, LED/LCD displays still have their benefits, including superior brightness and a lower price point. In general, the decision over whether to purchase an OLED or LED monitor will depend on factors like your budget, the tasks you are going to be using the monitor for, and the level of color accuracy you’ll need.

There are two main competing display technologies in the market today: LCD and OLED. The mature and dominant technology is the Liquid Crystal Display (LCD), while the up-and-coming challenger is the Organic Light Emitting Diode Display (OLED display). The main difference between LCD and OLED displays is how they create the light and the colors of the image being displayed. This leads to application dependent strengths and weaknesses of either technology.

OLEDs operate via a solid-state technology, where the individual pixels can emit light in various colors and intensity without the need for an additional light source or color filter. The light-emitting portion of an OLED display is comprised of multiple layers of very specific organic semiconductor materials which can be adjusted to emit light in specific wavelengths. These organic layers have a typical thickness in the order of 100nm. In addition, no backlight is required, allowing for a very thin display module.

The organic layers beginning on the cathode side of the device consist of several electron transport layers, a recombination layer and end with a hole transport layer on the anode side. The electron transport layers in the OLED stack-up allow movement of electrons from the cathode toward holes supplied from the anode. The electrons and holes recombine in the emissive recombination layer of the film stack-up. This recombination relaxes the energy levels of the electrons, which produces an emission of light. The wavelength of the emitted light is dependent on the chemical composition of the organic materials used in the recombination layer. The intensity of the light is controlled by the amount of current flowing through the OLED’s organic layers. In OLEDs, the individual pixels can emit red, green, or blue light, or – alternatively – they emit white light, which must then pass through color filters.

There are two main varieties of OLED screens: active-matrix and passive-matrix. The difference lies in how the pixels are generated. In the passive-matrix version, each pixel is created by the intersection of two wires, through which electrical current is passed to create a different color. In an active-matrix setup, each pixel has its individual transistor, which allows for faster refresh times and creates smoother motion and transitions in the picture.

In LCD display technology, the individual pixels modulate light. An applied voltage changes the orientation of liquid crystal molecules that – in conjunction with a pair of polarizers – function as a light shutter by either blocking or allowing light to pass through. LCD displays, therefore, require an additional light source, either from reflected ambient light or more commonly from a “backlight” (an array of LEDs arranged behind or next to the LCD panel). LCD color can be created by adding color filters to the individual pixels. Because OLED displays don’t require the additional backlight, polarizers, or color filter components of an LCD module, they can be made much thinner than LCD displays of equivalent size and resolution.

OLED display technology can offer power-saving advantages over LCDs, which is important, especially for battery-powered applications such as mobile phones. An OLED’s power consumption will vary with image content and brightness, as light is generated only at the individual pixels needed to display the image. A dark image or a graphic on a black background will consume much less power than bright images or graphics. In contrast, LCD backlights must be ON while the display operates. It’s possible to control individual zones of the backlight separately to save power, but this added complexity is usually only applied in larger displays.

OLEDs can achieve a much higher contrast ratio if reflections from the front surface are carefully controlled. If no current flows through an OLED pixel, it does not emit any light. In contrast the shutter effect of an LCD pixel does not block 100% of the light. Depending on the specific LCD technology used and the angle of observation, a small percentage of the light generated in the backlight can escape. This can wash out dark areas of an image. It is possible but expensive to limit this light leakage to a point where the contrast of an LCD and OLED display become perceptually equivalent.

RGB OLEDs naturally generate a narrow bandwidth of light. This leads to very saturated primary colors and a wide color gamut. This enables OLED technology to display colors which are not easily accessible to LCDs unless RGB backlights or quantum dots are used. Often OLED colors are used “as is”, however, for very high image color fidelity, such high color saturation needs to be electronically ‘tuned down’, to match the color bandwidth of the rendering chain.

LCDs offer an advantage over OLEDs in applications where a continuous static image is required. The light emitting materials in OLEDs are affected by luminance decay as a function of the total amount of current that has passed through the pixel. This decay differs for red, green and blue. The dimming effect is subtle, but when adjacent pixels are illuminated at the same time it can become noticeable as an undesired brightness variation or color shift. LCDs don’t suffer from this dimming effect, which makes them a more suitable solution for applications with static images or images with static elements.

Another advantage of LCD technology is the wide variety of different variations to choose from. Depending on the application certain trade-offs can be very attractive. An example is much lower cost for a laptop display compared to a tablet. This is achieved by allowing poor image performance when viewed from the direction the is usually blocked by the keyboard. In a tablet where good viewing performance is required from any direction, much higher cost LCDs or OLEDs must be used.

OLEDs offer an excellent solution for a variety of applications: Glucometers, thermometers, fitness trackers, professional audio equipment, Wi-Fi hotspots, radar detectors, dive computers, biometric transaction devices, and military communications equipment.

They can be used to replace old TN LCDs or add dynamic push buttons on industrial equipment. They can be customized to various resolutions, FPC configurations, colors, custom shaped OLED displays (e.g. octagonal, round, etc.) and can even be made into flexible and transparent displays. Thanks to their versatility, OLED display panel suppliers can offer some exciting capabilities for their customers – things that were previously impossible with LCDs.

Let’s start with the basics. There are basically two different kinds of iPhone displays. The first is LCD, which stands for liquid-crystal display. To simplify the explanation (and this is a significant simplification) let’s look at two of the components that make LCDs work. The first is their pixels, which are what dictate the colours that appear onscreen. Each pixel has three subpixels — one red, one green, and one blue — which each change in intensity. That combination of colours creates the images that appear when you scroll on Instagram, watch a YouTube video, or look at your photos.

The second component with LCDs is the backlight. The backlight is a panel that sits behind the pixels, and shines light through them in order for you to see what you see. When you change the brightness of your display, you’re really controlling the backlight, and it covers the entire display; think of it like a lightbulb — you can’t decide to have one part of the lightbulb getting brighter while another part gets dimmer.

The other type of iPhone display is OLED, short for organic light-emitting diode. The major difference between LCD and OLED displays is that there is no backlight in an OLED panel. Instead, the pixels lightthemselves up. That gives you some significant benefits; for one, you can have more finely detailed images, since each pixel stands out on its own, rather than requiring a backlight that covers all surrounding pixels as well. The biggest benefit, and the one you might see people talk about most, is that OLED pixels can turn themselves off, giving you incredible contrast between light and dark images.

These benefits are why I love OLED TVs in particular. The image is fantastic, and, when watching in a totally dark room, letterboxing bars just disappear; you only see the part of the screen you should (whether it be super widescreen or the old square format).

When it comes to iPhones, if you compare an LCD iPhone and an OLED iPhone and fill each display with a black rectangle, it would perfectly visualise the difference. The OLED iPhone would look like it was turned off; the LCD iPhone would still appear dark, but the display would be illuminated.

Because OLED pixels can turn themselves off, there are huge implications for battery life. You can save your iPhone some juice just by using dark mode, specifically the kind of dark mode that uses black backgrounds. (Grey ones won’t turn the pixels off, so you really need all-black elements to save your iPhone’s battery from having to power each and every pixel.)

Traditionally, the main flaw with OLED displays is burn-in. You see this a lot with OLED TVs, unfortunately; after an extended period of use, sometimes the “shadow” of static images will always remain on your screen. People who watch a lot of news, for example, complain that they can see the outline of the chyron, news ticker, and outlet logo on their TVs at all times.

That said, Apple has done a good job to prevent burn-in on OLED iPhones and it just isn’t a common complaint with these devices. The first OLED iPhone — the X — has been out since 2017, and in those four years, residual images haven’t been a noted issue. That’s to say, you don’t need to go out of your way to choose an LCD iPhone if you’re afraid of burn-in.

Below, I’ve listed each and every iPhone that Apple has ever made, complete with their display type. Some of these iPhones are quite old, but I’d love to know if you’re still rocking them. I should note that there are no new LCD iPhones; the last one Apple produced was the 2020 iPhone SE, and the iPhone 11 before that. The entire iPhone 12 and 13 lineups are made using OLED displays.

Shopping for a new TV sounds like it could be fun and exciting — the prospect of a gleaming new panel adorning your living room wall is enough to give you goosebumps. But with all the brands to choose from, and different smart capabilities (we can explain what a smart TV is) to weigh, as well as the latest picture tech to consider, it can be daunting. Is this article, we compare OLED vs. LED technology to see which is better for today’s modern TVs. Once you determine which panel type is best for you, make sure you check out our list of the best TVs to get our editor’s recommendations.

If you’re in the market for a TV, you’ve likely heard the hype regarding OLED models. They’re thin, light, and offer incredible contrast and color that’s second to none. OLED is only one letter apart from the more common display type, LED, so what gives? Can they really be that different? In a word: Yes. That extra “O” makes a big difference, but it doesn’t automatically mean an OLED TV will beat an LED TV in every use case. Some TV manufacturers like Samsung use their own technology, called QLED to confuse consumers even more. Make sure that you spend some time looking at our comparison piece: QLED vs. OLED technology before you make your purchase decision.

When OLED TVs first arrived in 2013, they were lauded for their perfect black levels and excellent color, but they took a bit of a hit due to brightness levels that couldn’t compete with LED TVs. There was also a huge price gap between OLED TVs (not to be confused with QLED) and their premium LED counterparts. In fact, legend has it that OLED used to mean “only lawyers, executives, and doctors” could afford them. Thankfully, that’s no longer the case.

OLED TVs are much brighter than they used to be, and the prices have come down, especially with brands like Sony introducing competitive options in 2021. The LED market is due for a bit of a shake-up, too. For now, however, it’s time to take a look at how these two technologies differ and explore the strengths and weaknesses of each.

Non-OLED TVs are made of two main parts: An LCD panel and a backlight. The LCD panel contains the pixels, the little colored dots that make up a TV’s image. On their own, pixels cannot be seen; they require a backlight. When light from the backlight shines through an LCD pixel, you can see its color.

The “LED” in LED TV simply refers to how the backlight is made. In the past, a thicker and less-efficient technology called CCFL (cold-cathode fluorescent light) was used. But these days, virtually every flat-screen TV uses LEDs as its source of backlighting. Thus, when you see the term “LED TV,” it simply refers to an LED-backlit LCD TV.

That said, not all LED TVs are created equal. There can be differences in the number and quality of the LEDs used, which leads to differences in things like brightness and black levels. You may also have seen something called “QLED TV.” This is
