On August 31, 2017, we started a long-term 20/7 burn-in test on 3 TVs (OLED vs VA vs IPS). Our goal was to see how their performance changed over time, especially with static images like network logos, black bars in movies, or video games with a fixed interface.

We already test for temporary image retention, which generally subsides over a few minutes. It"s a temporary annoyance and results in some faint artifacts usually visible in high contrast areas.

Permanent image retention is a more serious issue, but it requires looking at the TV"s performance over months or years. We tested three TVs side-by-side, the OLED LG B6, the VA Samsung KU6300, and the IPS LG UJ6300 in a two-year-long test.

This test ended in 2019, as we feel that we now have a good understanding of what types of content are likely to cause burn-in. However, we still haven"t addressed the issue of longevity in general, and we don"t know if newer OLED panels are still as likely to experience burn-in. To that end, we"ve decided to start a new accelerated longevity test to better understand how long new TVs should last and what are the most common points of failure. Although burn-in isn"t the main goal of this test, we"re hoping to better understand how newer OLED panels compare to the older generation of OLEDs. It"s generally accepted that burn-in isn"t as much of an issue as it used to be, but it"s unclear just how much better the newer OLED TVs are. With new panels, new heatsinks, and even brand-new panel types like QD-OLED, there are a lot of unknowns.

The 20/7 burn-in test ran for about two years, from August 31, 2017, until November 15, 2019. The goal of this test was to see whether burn-in could happen for the three most popular TV types (VA LCD, IPS LCD, and OLED). These are the results of our experiment:

Long periods of static content will cause burn-in on OLED TVs. The red sub-pixel appears to degrade the fastest, followed by green and blue. The effect is cumulative, as even cycled logos do burn-in (but over a longer period). We investigated this further in our Real Life OLED Burn-in Test.

Black letterbox bars were displayed for almost 5,000 hours (equivalent to 208 days of continuous letterboxing). Some letterboxing is starting to become noticeable on full-screen slides, but not in normal content. As a result, we don"t expect letterbox bars to cause any issues for people. It"s due to the uneven aging of the screen. The black portions of the screen haven"t aged as much as the rest, so those dark areas appear brighter in regular content.

Some of the LED backlights of the UJ6300 died, so the image is unwatchable. To keep a constant brightness of 175 nits across these TVs, the UJ6300"s backlight was turned up to maximum, while the other TVs achieved this brightness at a lower backlight/OLED Light setting. It may mean that it has been operating at a higher temperature, contributing to the failure.

The TVs were placed side-by-side in one of our testing rooms, as shown to the right. The TVs stayed on for 20 hours a day, seven days per week, running our test pattern in a loop. They were turned off for 4 hours each day using USB infrared transmitters connected to each TV and controlled by a PC to better represent normal (but still very heavy) usage. On the B6, the "Pixel Shift" option is enabled. A single Android TV Box was used as a source, with an HDMI splitter used to provide the same material to each display.

We used our calibration settings, as shown on the review page below, but with the backlight adjusted to reach 175 nits on our checkerboard pattern and no white balance settings applied.

A 5.5-hour video loop was used as the test pattern. It was designed to mix static content with moving images to represent typical content. The base material is a recording of over-the-air antenna TV with an overlay of RTINGS logos of different opacities and durations and added letterbox black bars. These additional elements are:

TFT LCD image retention we also call it "Burn-in". In CRT displays, this caused the phosphorus to be worn and the patterns to be burnt in to the display. But the term "burn in" is a bit misleading in LCD screen. There is no actual burning or heat involved. When you meet TFT LCD burn in problem, how do you solve it?

Burn in is a noticeable discoloration of ghosting of a previous image on a display. It is caused by the continuons drive of certain pixels more than other pixels. Do you know how does burn in happen?

When driving the TFT LCD display pixels Continously, the slightly unbalanced AC will attract free ions to the pixels internal surface. Those ions act like an addition DC with the AC driving voltage.

Those burn-in fixers, screen fixer software may help. Once the Image Retention happened on a TFT, it may easy to appear again. So we need to take preventive actions to avoid burn in reappearing.

For normal white TFT LCD, white area presenting minimal drive, black area presenting maximum drive. Free ions inside the TFT may are attracted towards the black area (maximum drive area)

When the display content changed to full screen of 128(50%) gray color, all the area are driving at the same level. Those ions are free again after a short time;

TFT LCD is a mature technology. OLED is a relatively new display technology, being used in more and more applications. As for Micro LED, it is a new generation technology with very promising future. Followings are the pros and cons of each display technology.

TFT Liquid Crystal Display is widely used these days. Since LCD itself doesn"t emit light. TFT LCD relies on white LED backlight to show content. This is an explanation of how TFT LCD works.

Relatively lower contrast：Light needs to pass through LCD glasses, liquid crystal layer, polarizers and color filters. Over 90% is lost. Also, LCD can not display pure black.

Organic Light-Emitting Diode is built from an electro-luminescent layer that contains organic compounds, which emit light in response to an electric current. There are two types of OLED, Passive Matrix OLED (PMOLED) and Active Matrix OLED (AMOLED). These driving methods are similar to LCD"s. PMOLED is controlled sequentially using a matrix addressing scheme, m + n control signals are required to address a m x n display. AMOLED uses a TFT backplane that can switch individual pixels on and off.

Stroboscopic effect: most OLED screen uses PWM dimming technology. Some people who are easy perceive stroboscopic frequency may have sore eyes and tears.

​Micro LED, sometimes called μLED is made up of tiny LED, measure less than 100μm. Another way of looking at this is that MicroLEDs are simply traditional LEDs shrunk down and placed into an array.

Replacing organic material with inorganic GaN material eliminates the need of polarizing and encapsulation layer, found in OLED. Micro LED is smaller and thinner, consumes less power.

I decided to make my own display that I can connect it to Raspberry pi or Jetson nano. so I"ve recently bought TFT 480x480 LCD with ST7701S and RGB interface. I think I"m providing valid signal, but It doesn"t seem to work, as It"s always black no matter what I do. but I"m not sure if the LCD is broken or I"m doing something wrong.

If you spend long enough debating the merits of LCD vs. OLED display technologies, eventually, someone will touch upon the subject of the dreaded OLED screen burn in. The point made is that OLED displays will inevitably suffer from horrible-looking artifacts over time, while LCD and new technologies like Mini-LED won’t. But like most of these debates, you’ll probably hear as many overblown anecdotes as you will actual facts about the issue.

You may never have experienced it for yourself, but many consumers are wary about the possibility of burn in when pondering their next smartphone purchase. Particularly as expensive flagship smartphones have universally adopted OLED display technology. Apple, Google, and other manufacturers acknowledge that burn in can be a problem in rare cases. OLED technology has made its way to much more affordable price points in recent years, putting the issue on the radar for even more consumers.

The word “burn in” is a little misleading, as no actual burning or heat problems are involved. Instead, this term describes a display suffering from permanent discoloration across any part of the panel. This may take the form of a text or image outline, fading of colors, or other noticeable patches and patterns on display. The display still works as expected, but a somewhat noticeable ghost image or discoloration persists when the screen is on. To be considered screen burn in, these artifacts have to be permanent and are a defect caused on the display hardware side. Rather than a graphical glitch that may be caused by software, temporary image retention, or a problem with the display driver circuitry.

The term dates back to old CRT monitors, where phosphor compounds that emit light to produce images lost their luminance with time. LCD panels can exhibit similar problems, but these are much rarer due to the nature of LCD’s backlight and color matrix design.

Although not as bad or noticeable as old CRT issues, today’s OLED smartphone displays can eventually suffer from a similar problem. That being said, it’s pretty difficult and rare to notice unless you know what you’re looking for, and it takes hundreds, if not thousands, of hours of screen-on time before any such errors appear. In smartphones, pattern burn in is typically associated with always-on displays, navigation buttons, and the notification bar. The example below demonstrates a textbook case:

Although most smartphones now support gesture navigation controls in the place of the old button design. So this type of burn-in is much less of a problem than it used to be.

The cause of all screen burn in is the varying lifecycle of a display’s light-producing components. As these parts age, their brightness changes, and therefore the panel’s color reproduction gradually shifts with time. Although this can be mitigated somewhat with clever software, all displays experience some color shift as they age. But with burn in, some parts of the screen age faster than others. This can gradually shift the perceivable colors of the screen in one area more than in another, leaving what looks like a ghost image behind.

With modern smartphone and smartwatch technology, screen burn in can manifest due to the different life spans between the red, green, and blue LED subpixels used in OLED panels. As we mentioned before, areas of the display that seldom change, are bright white, or are often black and switched off, such as navigation buttons or the notification bar, are the most likely areas to notice this issue. You may also notice the effect in darkened status bars designed to hide display notches.

This is because these areas are more likely to consistently display one color, a set icon, or text. In contrast, the rest of the display produces a more random selection of colors from various websites, videos, apps, etc., over a long period of use. Therefore the subpixels in these areas see different amounts of use and thus age differently, eventually resulting in a slight variation in color reproduction. Switching to transparent and color-changing bars has the added bonus of evening out the color aging process.

Speaking more technically, the issue is that blue LEDs have significantly lower luminous efficiency than red or green pixels. This means that a blue LED needs to be driven at a higher current for a set sized pixel to achieve the same brightness as red or green. Higher current causes the pixel to degrade faster, shortening its lifespan and eventually tinting the display towards the red and green colors. Therefore an OLED display’s color doesn’t degrade evenly; it will ultimately lean towards a red/green tint.

So, if one part of the panel spends a lot of time displaying a blue or white image, the blue pixels in this area will degrade faster than in other areas. That’s essentially what burn in is. However, display manufacturers do account for this in their panel designs.

If OLED screens have a problem with burn in, why do we continue using them? Burn in is a true downside to OLED displays, but there are plenty of reasons consumers and manufacturers like them. For starters, image quality is much better than in LCDs. OLED panels can reproduce more vibrant colors, more contrast, wider viewing angles, and faster refresh rates. Colors tend to be much more saturated, and blacks are much darker.

OLED displays have a simpler design, allowing thinner, lighter smartphone designs. You can also thank OLED technology for foldable phones and curved displays. If those improvements weren’t enough, you’ll also enjoy lower power consumption with OLED.

Additionally, burn in problems are only common after prolonged periods of use. As you may already know, smartphone manufacturers don’t expect you to keep a smartphone for more than 2-3 years. Recent statistics show that consumers currently keep their phones for an average of 2.75 years.

At this stage, manufacturers are very aware of the potential issues and have already taken some intelligent steps to help avoid burn in. For starters, Samsung has been using its pentile subpixel arrangement in its AMOLED displays since the Galaxy S3. By making the blue subpixel larger, it requires less current to drive in order to provide the necessary light. Driving the LED with less current increases its lifespan, so it takes longer for any noticeable color shift to occur.

This doesn’t directly address the issue of different parts of the screen aging at different rates, but it does mean that it will take significantly longer to notice than with older or cheaper OLED panels. More expensive and modern OLED panels are built with longer-lasting LEDs and well-designed layouts, meaning flagship smartphone displays age slower. These days, it’s cheaper phones packing cheaper displays that are marginally more likely to see issues after heavy use.

There are software solutions too. Android Wear product manufacturers can enable the OS’s “burn protection” option. This mode periodically shifts the screen’s contents by a few pixels, so they spend equal time displaying different colors. Smartphones equipped with Always-On display technology employ a similar tactic. Google also suggests a selection of design guidelines tailored to avoid screen burn-in problems when designing OLED watches. The move towards gesture rather than on-screen navigation controls is also helping to alleviate one of the more noticeable burn in areas.

If your screen is already burnt in, there’s not much that can be done to undo the damage. Some apps on the Play Store claim to reverse the problem. These will end up “burning” the rest of the screen to match the colors, which isn’t a real solution.

Keep your display brightness as low as reasonable. Increased brightness requires more current and therefore shortens LED lifespans. Don’t crank up the brightness unless you have to.

Try to make it so that the screen isn’t displaying the same thing all the time, in the same areas of the screen. For example, if you have a widget that almost always looks the same, chances are it will eventually burn into the image. Move things around now and then, and try to keep the view of your phone dynamic.

All that said, screen burn in isn’t something that should concern many users if they’re looking to buy a new OLED smartphone. Modern panels have much longer lifespans than early OLED smartphones, and even then, burn in was rare. Just don’t leave a static image on the screen 24/7 with the brightness set at max.

The bottom line is that you should be looking at several years’ worth of use out of a modern smartphone display before any screen burn in will be noticeable. But it doesn’t hurt to be aware of what can happen to aging handsets and how to maximize their lifespan.

Well, I really want to like it. One thing I can definitely say for it is that the resolution and clarity of the screen is excellent. Oddly, the color/brightness settings are weird though. To get it about where an decent screen should be, I had to set brightness all the way down to 33 and both contrast and saturation had to actually go way up to 75 or so. (I don"t really have a calibration guide handy, so this was eyeballing it.) Note that this has no backlight adjustment -- this is a software brightness setting that barely changes it by a lot (so mostly a higher setting just washes things out.) Contrast almost seems to adjust sharpness more than actual contrast as well, which is strange, so it needs to be higher but does worse if you go too high. When you set things connected to it to produce 1024x600 resolution the clarity with these settings is beyond amazing for such a tiny screen though. Even at a HDMI default of 720p it"s actually pretty good. It also seems to be _VERY_ tolerant of outside resolutions. I accidentally typed 1024x700 and it took me a while to figure out what was wrong because it not only accepted the resolution, but resized it very well and it was still very clear. That"s a pretty huge plus right there and would have been worthy of at least four stars. If it wasn"t for the viewing angle...

Unfortunately, this is where it loses significant points. If I were rating it on viewing angle alone it would get one star even. I"ve never seen a screen this bad in that respect and I have used laptops in the MS-DOS days when LCD latencies were practically measured in seconds rather than milliseconds (pro-tip, NEVER play Descent on a laptop with really really high LCD latency. You WILL be sick.) Left and right viewing angle are great -- which is ironic because in most applications for this thing left and right aren"t that big of an issue -- but the up and down viewing angle literally couldn"t be any worse. Specifically, you can NOT look at this thing directly straight on. It MUST tilt up away from you so you"re basically looking up at it somewhat. I would estimate it has to go about 25-30 degrees or so off from being parallel. That"s pretty extreme to the point of being a bit ridiculous. The stand doesn"t do high precision either on the tilt, so you won"t really get it at quite an optimal angle and just have to get it as close as you can (about 35 or so I guess is what it works out to if you get it on the closest catch and then tilt it just a bit.) If you get at all close to looking at it parallel it turns insanely dark and you can"t see details or color well at all -- even text is insanely hard to read. As you approach 90 degrees, it starts to invert before you even actually get to a straight head-on look at it. Any higher and it outright inverts. If you can tilt it just right, the colors are pretty close to an IPS panel almost even (a bit lacking compared to a real IPS, but better than most TFT panels.) But this unreasonable viewing angle is extremely offputting. Also, as a side effect, since it has to stay tilted upwards, this means it collects dust like there is no tomorrow. That"s even more offputting. If it didn"t have such good visual clarity and color production I"d have to give it only one star even. Unfortunately, no matter how you position it, it will never be QUITE right with colors a bit more washed than they should be at one angle and too dark to even see at another. If you"re buying this just to act as a camera monitor or a simple screen for a server or something it will work great, but if you buy it for handling something like an OpenElec system, you"ll probably be very unhappy with the ridiculous viewing angle.

One thing that is either good or bad depending on how you look at it is the HDMI port _does_ provide power. This means some plug-in devices will work. However, it doesn"t provide much. My guess is it"s limited to the usual 500mA of official USB specifications, but that"s just a guess. It makes my Raspberry Pi try to turn on even while the power plug is removed but keep rebooting over and over. (I"m using BerryBoot so it doesn"t begin any processes where data writing may occur and no harm is done, but this is very irritating.) However, if you use a minimal HDMI switch or anything like that you"ll probably be grateful that it does provide HDMI power. In fact, I"d go so far as to say this is more of a fault in the power design of the Raspberry Pi that it accepts such power where most HDMI power sources will likely be insufficient to actually handle a RPi (and therefore the RPi shouldn"t accept power from the HDMI port by default -- with maybe just a simple trace you can connect to enable it or something.)

(hdmi_drive may not be needed. I had a typo in mine and only noticed when I was copying and pasting here, so all this time it was not using it, but it was definitely going to 1024x600 in everything as verified both via software and the screen itself. It is hdmi_group and hdmi_mode that forces it to use the custom resolution defined by hdmi_cvt.)

EDIT: I finally broke down and pulled it apart, hoping it was an issue of an incorrectly placed filter resulting in the wrong polarity. Unfortunately no such luck. I think actually the main problem is that they chose to only place backlight LEDs at the very top with not very good plastic pieces being supposed to carry it all around. This results in less and less actual backlight towards the bottom. This is a design choice that I don"t know how an end user can compensate for or fix really.

TFT stands for thin-film transistor, which means that each pixel in the device has a thin-film transistor attached to it. Transistors are activated by electrical currents that make contact with the pixels to produce impeccable image quality on the screen. Here are some important features of TFT displays.Excellent Colour Display.Top notch colour contrast, clarity, and brightness settings that can be adjusted to accommodate specific application requirements.Extended Half-Life.TFT displays boast a much higher half-life than their LED counterparts and they also come in a variety of size configurations that can impact the device’s half-life depending on usage and other factors.TFT displays can have either resistive or capacitive touch panels.Resistive is usually the standard because it comes at a lower price point, but you can also opt for capacitive which is compatible with most modern smartphones and other devices.TFT displays offer exceptional aspect ratio control.Aspect ratio control contributes to better image clarity and quality by mapping out the number of pixels that are in the source image compared to the resolution pixels on the screen.Monitor ghosting doesn’t occur on TFT displays.This is when a moving image or object has blurry pixels following it across the screen, resembling a ghost.

TFT displays are incredibly versatile.The offer a number of different interface options that are compatible with various devices and accommodate the technical capabilities of all users.

There are two main types of TFT LCD displays:· Twisted nematic TFT LCDs are an older model. They have limited colour options and use 6 bits per each blue, red, and green channel.

In-plane switching TFT LCDs are a newer model. Originally introduced in the 1990s by Hitachi, in-plane switching TFT LCDs consist of moving liquid pixels that move in contrast or opposite the plane of the display, rather than alongside it.

Relies on backlighting to provide brightness rather than producing its own light, hence, they need built-in light emitting diodes (LEDs) in their backlighting structure

The type of TFT LCD monitor or industrial display you choose to purchase will depend on the specifications of your application or project. Here are a few important factors to consider when selecting an appropriate TFT LCD display technology:Life expectancy/battery life.Depending on the length of ongoing use and the duration of your project, you’re going to want to choose a device that can last a long time while maintaining quality usage.

Touch type and accuracy.What type of activities are you planning on using your device for? If it’s for extended outdoor use, then you should go with projected capacitive touch as this is more precise and accurate. Touch accuracy is important for industrial and commercial applications.

Image clarity.Some TFT displays feature infrared touchscreens, while others are layered. The former is preferable, especially in poor lighting conditions or for outdoor and industrial applications, because there’s no overlay and therefore no obstructions to light emittance.

The environmental conditions make a difference in operation and image clarity. When choosing a TFT for outdoor or industrial applications, be sure to choose one that can withstand various environmental elements like dust, wind, moisture, dirt, and even sunlight.

AMOLED and TFT are two types of display technology used in smartphones. AMOLED (active-matrix organic light-emitting diode) displays are made up of tiny organic light-emitting diodes, while TFT (Thin-Film Transistor) displays use inorganic thin-film transistors.

AMOLEDs are made from organic materials that emit light when an electric current is passed through them, while TFTs use a matrix of tiny transistors to control the flow of electricity to the display.

Refresh Rate: Another key difference between AMOLED and TFT displays is the refresh rate. The refresh rate is how often the image on the screen is updated. AMOLED screens have a higher refresh rate than TFT screens, which means that they can display images more quickly and smoothly.

Response Time: The response time is how long it takes for the pixels to change from one colour to another. AMOLED screens have a shorter response time than TFT screens..

Colour Accuracy/Display Quality: AMOLED screens are more accurate when it comes to displaying colours. This is because each pixel on an AMOLED screen emits its own light, which means that the colours are more pure and true to life. TFT screens, on the other hand, use a backlight to illuminate the pixels, which can cause the colours to appear washed out or less vibrant.

Viewing Angle: The viewing angle is the angle at which you can see the screen. AMOLED screens have a wider viewing angle than TFT screens, which means that you can see the screen from more angles without the colours looking distorted.

Power Consumption: One of the main advantages of AMOLED displays is that they consume less power than TFT displays. This is because the pixels on an AMOLED screen only light up when they need to, while the pixels on a TFT screen are always illuminated by the backlight.

Production Cost: AMOLED screens are more expensive to produce than TFT screens. This is because the manufacturing process for AMOLED screens is more complex, and the materials used are more expensive.

Availability: TFT screens are more widely available than AMOLED screens and have been around for longer. They are typically used in a variety of devices, ranging from phones to TVs.

Usage: AMOLED screens are typically used in devices where power consumption is a concern, such as phones and wearable devices. TFT screens are more commonly used in devices where image quality is a higher priority, such as TVs and monitors.

AMOLED and TFT are two different types of display technology. AMOLED displays are typically brighter and more vibrant, but they are more expensive to produce. TFT displays are cheaper to produce, but they are not as bright or power efficient as AMOLED displays.

The display technology that is best for you will depend on your needs and preferences. If you need a screen that is bright and vibrant, then an AMOLED display is a good choice. If you need a screen that is cheaper to produce, then a TFT display is a good choice. However, if you’re worried about image retention, then TFT may be a better option.

Steven Van Slyke and Ching Wan Tang pioneered the organic OLED at Eastman Kodak in 1979. The first OLED product was a display for a car stereo, commercialized by Pioneer in 1997. Kodak’s EasyShare LS633 digital camera, introduced in 2003, was the first consumer electronic product incorporating a full-color OLED display. The first television featuring an OLED display, produced by Sony, entered the market in 2008. Today, Samsung uses OLEDs in all of its smartphones, and LG manufactures large OLED screens for premium TVs. Other companies currently incorporating OLED technology include Apple, Google, Facebook, Motorola, Sony, HP, Panasonic, Konica, Lenovo, Huawei, BOE, Philips and Osram. The OLED display market is expected to grow to $57 billion in 2026.

AMOLED (Active Matrix Organic Light Emitting Diode) is a type of OLED display device technology. OLED is a type of display technology in which organic material compounds form the electroluminescent material, and active matrix is the technology behind the addressing of individual pixels.

An AMOLED display consists of an active matrix of OLED pixels generating light (luminescence) upon electrical activation that have been deposited or integrated onto a thin-film transistor (TFT) array, which functions as a series of switches to control the current flowing to each individual pixel.

Typically, this continuous current flow is controlled by at least two TFTs at each pixel (to trigger the luminescence), with one TFT to start and stop the charging of a storage capacitor and the second to provide a voltage source at the level needed to create a constant current to the pixel, thereby eliminating the need for the very high currents required for PMOLED.

TFT backplane technology is crucial in the fabrication of AMOLED displays. In AMOLEDs, the two primary TFT backplane technologies, polycrystalline silicon (poly-Si) and amorphous silicon (a-Si), are currently used offering the potential for directly fabricating the active-matrix backplanes at low temperatures (below 150 °C) onto flexible plastic substrates for producing flexible AMOLED displays. Brightness of AMOLED is determined by the strength of the electron current. The colors are controlled by the red, green and blue light emitting diodes.  It is easier to understand by thinking of each pixel is independently colored, mini-LED.

IPS technology is like an improvement on the traditional TFT LCD display module in the sense that it has the same basic structure, but with more enhanced features and more widespread usability compared with the older generation of TN type TFT screen (normally used for low-cost computer monitors). Actually, it is called super TFT.  IPS LCD display consists of the following high-end features. It has much wider viewing angles, more consistent, better color in all viewing directions, it has higher contrast, faster response time. But IPS screens are not perfect as their higher manufacturing cost compared with TN TFT LCD.

Utilizing an electrical charge that causes the liquid crystal material to change their molecular structure allowing various wavelengths of backlight to “pass-through”. The active matrix of the TFT display is in constant flux and changes or refreshes rapidly depending upon the incoming signal from the control device.

The other thing to bear in mind, for a clock being used 24/7, even if there is burn-in it will be where you always have the same graphics so not really problematic. It"s only when displaying something else that burn-in can be annoying.

Static dials or surrounds and fixed markings would be first to exhibit burn-in if that did happen. Moving hands, changing dates, and other information would be much less likely to burn-in.

Shifting the display left, right, up or down on a daily basis might help avoid some burn-in without being visually noticeable but I don"t believe there would be much of an issue if you don"t.

For many of us, a lot of the screens we view daily can easily be OLED. The iPhone in your pocket. The screen on the new laptop you finally bought. That luxurious 4K TV and even that beloved Nintendo Switch. But OLED awesomeness has far from proliferated computer monitors—especially if you"re not into gaming.

Numerous hurdles limit OLED monitor adoption, including concerns about screen burn-in. But one thing we"re hoping to see in 2023 is a greater selection. Right now, you can count the number of OLED monitors that aren"t 42-inch-plus juggernauts or push refresh rates that require serious GPUs on one hand. OLED monitors that focus on productivity, photo editing, or HDR get minimal love.

By the time 2023"s done, we hope there"s more than a handful of OLED monitors available to interest non-gamers. We don"t expect homes and offices to become flooded with them, but 2023 could be a big step to OLED monitors having the variety and availability that OLED TVs and other devices have enjoyed for years.

First, let"s tamp down expectations. OLED monitors are far from mainstream among PC displays, and that won"t shift dramatically next year. In September, market researcher Trendforce predicted that OLED monitors will represent 2 percent of the monitor market in 2023. That"s far from mainstream. IPS monitors, for instance, represented 43 percent of monitors shipped in 2021.

Business consultant and market researcher UBI Research, via OLED-Info, estimated that OLED tablets, monitors, and laptops for "IT applications" will increase from 9.5 million units this year to 48.8 million units by 2027.

So, if we had to bet on what type of monitor any given person was buying in the next year or two, our chips would be on LCD. Advertisement

And with supply and demand closely tied together, desktop-sized OLED monitors remained a rarity this year, with options being even skimpier if you want a non-gaming display under 42 inches. Here"s the dizzying list of four:

Computer users had plenty of OLED laptops to consider this year, though, from the HP Spectre x360 2-in-1 to Dell"s flagship XPS 13 Plus clamshell ultraportable. But considering the association between OLED laptops, high prices, and lower battery life, there"s a reason to get an OLED from a dedicated monitor instead.

Most OLED monitors are in the 40-inch class with ultra-high resolutions, attaching a size-related premium to an already expensive technology. But the end of this year already promises greater variety in terms of monitor size, resolution, and price.

LG will start selling its first OLED monitors with high refresh rates on December 12, The Verge reported this week. The 26.5-inch, 2560×1440 LG UltraGear 27GR95QE-B will have a $1,000 MSRP, and the 45-inch, 3400×1440 LG 45GR95QE-B is $1,700.

It"s also possible we"ll see the release of a bendable OLED monitor next year. Corsair hasn"t confirmed when its Xeneon Flex 45WQHD240 will come out or for how much, but it teased the 45-inch, 3440×1440 gaming monitor in September.

The 27-inch Philips 27E1N8900 4K video editing monitor was supposed to release in the US for around $1,070, which would be a competitive size and price, a What HiFI report said in May, but we"ve yet to hear from Philips.

Further, we could see OLED monitors next year or beyond with even smaller designs. LG Display is reportedly working on 20-inch OLED panels that could be used in small monitors.

When it comes to choosing what to use for your displays, going with the standard can get you farther ahead than thinking outside the box. TFT LCD display gives you an edge for your advertising needs, television screens, or even phone screens.

A thin-film transistor (TFT) is one of the technologies commonly used for building LCDs. With this technology, your LCD is guaranteed a sharp, clear, and full-color display and high-quality performance.

When a signal sent to a pixel also affects the pixels next to it, crosstalk This runs the risk of distorting the quality of your image. With TFT, crosstalk is significantly reduced with the TFT layer integrated into the screen itself. With every pixel corresponding to the signals meant only for them, you are guaranteed the best resolution and image quality.

In the LCD industry, the most popular kinds of displays are manufactured and innovated the most. Unlike other types of LCD technologies, the TFT module is available in different sizes, ranging from cellphone sizes to larger TV sizes, to suit your needs.

All LCD displays have a determined number of hours of use before they become half as bright than when they were turned on for the first time. This is called half-life. Although research is still ongoing regarding half-life, TFT displays are said to have more than 14,000 hours of half-life.

This does not mean, however, that the LCD will burn out after reaching its half-life. It means that its brightness will only be half of when it was new.

Compared to CRTs, TFT LCD modules have lower heat release. Moreover, they emit lower electromagnetic emissions which significantly decrease visual fatigue. This means that TFTs are ideal for devices and displays that require an audience’s prolonged attention, such as cell phones and television screens.

While the TFT’s power consumption is significantly lower than OLEDs in white displays, there are also emerging TFT displays in the market that integrate smart technologies that can save up to 50% energy on battery-operated devices.

One of the notable disadvantages of TFTs, however, is its cost. The characteristics detailed in the previous section, however, must be considered worthy of investment. Moreover, as the number of TFTs floods the LCD display market, the price for TFTs are decreasing by the day.

At Microtips Technology USA, we only provide you with the best among the best of TFT modules. Our TFT LCD displays assure only full RGB brilliance with up to 16.7 million colors, better picture quality with high resolutions and IPS technology, and affordability.

If we talk about mobile phone screens, then the most debated is definitely LCD and OLED, but with the development of technology, OLED has the momentum of replacing LCD, now smart phones, it is difficult to see the voice of LCD, these days want to buy a LCD phone has not been easy.

In addition, OLED began to conquer the TV circle, Xiaomi just released a 55-inch OLED TV price was dry to 4999 yuan price, I believe it will not be long, OLED TV is not unattainable products, into thousands of households, OLED TV compared to LCD TV can be said to be crushed, then the status of LCD will be very embarrassing.

Next is between the TV and mobile phone zone, that is, the computer, OLED in the computer circle has been very slow to promote the speed, in fact, on the one hand because of the cost, on the other hand is the discomfort, unlike the TV and mobile phone, computer display screen is often static.

Because whether it is office software or design software, or even video editing software, these software have a large area is static display, and OLED has one of the biggest problems, that is, burning screen, and no matter how the technology to improve, this is from difficult to fundamentally avoid.

So the PC field, OLED has been slow progress, but with the development of technology, has begun to have a number of laptops began to use OLED screen, and the number of OLED computer monitors is also increasing, which means that LCD may also be driven out of this most unlikely to lose the PC position.

Mobile phones, TVs, PCs, if they are all taken by OLED, then there is not much space left for LCD, but when it comes to this, many people have questions, often heard others say OLED burn screen, and from the principle of OLED burn screen is very difficult to avoid, why they use so many OLED mobile phones, but never encountered a burn screen.

In fact, when OLED first came out, it is indeed very easy to burn screen, because of the independent light-emitting reason, the life of each sub-pixel is different, different attenuation, time will leave traces on the screen, so the mobile phone business began to work on the arrangement, such as we often hear the Zhou Dong Yu arrangement, or diamond arrangement, these programs are shared sub-pixel method, which will lead to a decline in PPI, but to a large extent to avoid burning screen.

Of course, in addition to the arrangement, screen manufacturers also work on materials, the introduction of more durable materials, software algorithms to optimise, such as pixel shift, as a way to avoid burning screen occurrence, with these measures, then the average person will be very difficult to encounter burned screen.

Mobile devices are special, in fact, the main reason why OLED is afraid of burning screen is afraid of long time display static screen, but for mobile phones, there should be very few people will display static screen for a long time, most of the scenes are dynamic, watch videos, daily brush screen, play games, these do not cause burning screen, to burn the screen of mobile phones, you need the phone to display static screen for a long time.

The third is that it is not easy to burn the screen, OLED life can already exceed 20,000 hours, that is, according to 20 hours a day, it also takes 1000 days, and this is still in the case of high brightness, so to achieve this intensity of use, should first consider not the mobile phone screen, but their eyes, in fact, most people play mobile phones every day, the average time of the screen electric light down to less than 10 hours, so want to use the screen is really not easy.

It is for these reasons that the probability of OLED burning screen can now be said to have reached the point of negligence, indeed there are still people who will roll over, but most people can successfully use to retirement, so they will not encounter the problem of burning screen, precisely because it is a very small probability event, most people are naturally very difficult to encounter, so burning screen is like a mirage, have heard, but most of them do exist. It"s a mirage.
