pantalla pls tft lcd vs super amoled price
Thanks for the display technology development, we have a lot of display choices for our smartphones, media players, TVs, laptops, tablets, digital cameras, and other such gadgets. The most display technologies we hear are LCD, TFT, OLED, LED, QLED, QNED, MicroLED, Mini LED etc. The following, we will focus on two of the most popular display technologies in the market: TFT Displays and Super AMOLED Displays.
TFT means Thin-Film Transistor. TFT is the variant of Liquid Crystal Displays (LCDs). There are several types of TFT displays: TN (Twisted Nematic) based TFT display, IPS (In-Plane Switching) displays. As the former can’t compete with Super AMOLED in display quality, we will mainly focus on using IPS TFT displays.
OLED means Organic Light-Emitting Diode. There are also several types of OLED, PMOLED (Passive Matrix Organic Light-Emitting Diode) and AMOLED (Active Matrix Organic Light-Emitting Diode). It is the same reason that PMOLED can’t compete with IPS TFT displays. We pick the best in OLED displays: Super AMOLED to compete with the LCD best: IPS TFT Display.
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.
What Are the Main Differences between AMOLED and TFT Displays?Backlight: One of the main differences between AMOLED and TFT displays is how they are lit up. A backlight is used to light up TFT screens, while AMOLED screens are self-illuminating. This means that TFT displays require more power to operate than AMOLED displays.
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.
Roughly speaking there are two main types of displays used in smartphones: LCD and LED. These two base technologies have been refined and tweaked to give us AMOLED and IPS LCD. The former stands for Active Matrix Organic Light-Emitting Diode, while the latter means In-Plane Switching Liquid Crystal Display.
All of this hasn’t gone unnoticed by the marketing people, which means that plain old AMOLED or regular IPS LCD aren’t the terms used in the marketing fluff. Instead, we have Super AMOLED, Dynamic AMOLED, Super LCD, Super Retina OLED, Super Retina XDR, Infinity Display, and so on. But what’s any of that actually mean?
The LED part of AMOLED stands for Light Emitting Diode. It’s the same tech as you find on many home appliances that show that the power is on with a little red light. An LED display takes this concept, shrinks it down, and arranges the LEDs in red, green, and blue clusters to create an individual pixel.
The O in AMOLED stands for organic. It refers to a series of thin organic material films placed between two conductors in each LED. These produce light when a current is applied.
Finally, the AM part in AMOLED stands for Active Matrix, rather than a passive matrix technology. In a passive matrix, a complex grid system is used to control individual pixels, where integrated circuits control a charge sent down each column or row. But this is rather slow and can be imprecise. Active Matrix systems attach a thin film transistor (TFT) and capacitor to each sub-pixel (i.e. red, green, or blue) LED. The upshot is that when a row and column is activated, the capacitor at the pixel can retain its charge in between refresh cycles, allowing for faster and more precise control.
The image above is a close-up shot of the AMOLED display on the Samsung Galaxy S8. The RGB triangular pattern is clearly shown. Towards the bottom of the image, the green and red LEDs are off and the blue LEDs are on only slightly. This is why AMOLED displays have deep blacks and good contrast.
Super AMOLED is a marketing term from Samsung. It means a display that incorporates the capacitive touchscreen right in the display, instead of it being a separate layer on top of the display. This makes the display thinner.
Dynamic AMOLED is another marketing term from Samsung. It denotes Samsung’s next-generation AMOLED display which includes HDR10+ certification. According to Samsung, Dynamic AMOLED also reduces the harmful blue light emitted from the display, which helps reduce eye strain and helps lessen sleep disturbances if you’re using your phone late in the day!
As for Infinity Display (or Infinity-O Display), it is more marketing from Samsung. It means “a near bezel-less, full-frontal, edge-to-edge” display. However, it is still a Super AMOLED unit.
LCD displays work with a backlight that shines through some polarizing filters, a crystal matrix, and some color filters. Liquid crystals untwist when an electric charge is applied to them, which affects the frequency of the light that can pass through. Since the crystals can be twisted to varying degrees depending on the voltage used, a display can be built when they are used with polarized panels. A grid of integrated circuits is then used to control each pixel, by sending a charge down into a specific row or column. Colors are created by the use of red, green, and blue filters, known as sub-pixels, which are then blended by varying degrees to produce different colors.
The above image is of an LCD display from a Huawei Mate 8. Notice how the pixels are made up of equally-sized sub-pixels, one for each of the colors: red, green, and blue.
Like Super AMOLED, a Super LCD display also incorporates the touchscreen. There is no “air gap” between the outer glass and the display element, which means it has similar benefits to Super AMOLED.
All Retina and Retina HD displays on the iPhone are LCD IPS displays. However, things have changed a bit with the iPhone X as it features an AMOLED display, now marketed under the term Super Retina. It’s still an AMOLED display. It just has extra adjectives. With the launch of the iPhone 11 Pro, Apple coined the term Super Retina XDR. The XDR part means Extended Dynamic Range, as they have better contrast ratios and higher peak brightness.
Not all Retina displays use OLED. Although the MacBook Pro is marketed with a “Retina” display, as you can see from the magnified image above, it is a regular LCD, even if it uses the latest Apple silicon.
Both technologies can be used to build displays with 720p, 1080p, Quad HD, and 4K resolutions. And OEMs have made handsets that support HDR10 using both LCD and AMOLED displays. So from that point of view, there isn’t much difference between the two.
When it comes to color, we know that the blacks will be deeper and the contrast ratios higher on AMOLED displays. But, overall color accuracy can be high on both types of display.
One of the main weaknesses of AMOLED displays is the possibility of “burn-in”. This is the name given to a problem where a display suffers from permanent discoloration across parts of the panel. This may take the form of a text or image outline, fading of colors, or other noticeable patches or patterns on the display. The display still works as normal, but there’s a noticeable ghost image or discoloration that persists. It occurs as a result of the different life spans between the red, green, and blue LED sub-pixels used in OLED panels.
The theoretical lifespan of an AMOLED display is several years, even when used for 12 hours a day. However, there is anecdotal evidence that some displays suffer from burn-in quicker than others. Displays that show signs of burn-in after only a few months should be considered defective because they certainly aren’t normal.
While owners of devices with LCD screens might congratulate themselves for picking a smartphone that is immune to burn-in, there can be a problem with LCD panels called “image retention.” Put simply, liquid crystals can develop a tendency to stay in one position when left at the same voltage for extended periods. Thankfully this phenomenon is normally temporary and can usually be reversed by allowing the liquid crystals to return to their relaxed state.
Picking a winner can be hard as there are many factors to consider, not only about the display technologies but also about the other components in a handset. For example, if you are an AMOLED fan, then would you consider a device with large storage and a good processor, but with an LCD display? The same argument works the other way for LCD fans. Generally, you’ll be fine with either display type, so just pick the handset you like.
Higher-end devices typically sport AMOLED displays and mid-range/budget devices usually use LCD. But that isn’t set in concrete as there are plenty of high-end devices that have LCD displays. With OLED production costs dropping dramatically in recent years, more and more budget options will be offering OLED panels in the future.
Companies like LG and Samsung have seen this trend coming and are rapidly expanding their OLED (and flexible OLED) production capabilities. LCD might still have a bright future in televisions and other large-panel applications, but for now, it looks like mobile will be increasingly dominated by OLED screens.
What do you think? AMOLED or LCD? What about the terms like Retina vs Infinity Display? Are they meaningful to you? Please let me know in the comments below.
Mobile display technology is firmly split into two camps, the AMOLED and LCD crowds. There are also phones sporting OLED technology, which is closely associated with the AMOLED panel type. AMOLED and LCD are based on quite different underlying technologies, leading manufacturers to tout a number of different benefits depending on which display type they’ve opted for. Smartphone manufacturers are increasingly opting for AMOLED displays, with LCD mostly reserved for less expensive phones.
We’ll start alphabetically with AMOLED, although to be a little broader we should probably start with a little background about OLED technology in general.
The arrangement of these sub-pixels alters the performance of the displays slightly. Pentile vs striped pixel layouts, for example, results in superior image sharpness, but lower pixel life spans due to the smaller pixel sizes.
Finally, the AM part in AMOLED stands in for Active Matrix, rather than a passive matrix technology. This tells us how each little OLED is controlled. In a passive matrix, a complex grid system is used to control individual pixels, where integrated circuits control a charge sent down each column or row. But this is rather slow and can be imprecise. Active Matrix systems attach a thin film transistor (TFT) and capacitor to each LED. This way, when a row and column are activated to access a pixel, the capacitor at the correct pixel can retain its charge in between refresh cycles, allowing for faster and more precise control.
One other term you will encounter is Super AMOLED, which is Samsung’s marketing term for a display that incorporates the capacitive touchscreen right into the display, instead of it being a separate layer on top of the display. This makes the display thinner.
The use of LEDs and minimal substrates means that these displays can be very thin. Furthermore, the lack of a rigid backlight and innovations in flexible plastic substrates enables flexible OLED-based displays. Complex LCD displays cannot be built in this way because of the backlight requirement. Flexy displays were originally very promising for wearables. Today, premium-tier smartphones make use of flexible OLED displays. Although, there are some concerns over how many times a display can flex and bend before breaking.
LCD stands for Liquid Crystal Display and reproduces colors quite differently from AMOLED. Rather than using individual light-emitting components, LCD displays rely on a backlight as the sole light source. Although multiple backlights can be used across a display for local dimming and to help save on power consumption, this is more of a requirement in larger TVs.
Scientifically speaking, there’s no individual white light wavelength. White light is a mixture of all other visible colors in the spectrum. Therefore, LCD backlights have to create a pseudo white light as efficiently as possible, which can then be filtered into different colors in the liquid crystal element. Most LCDs rely on a blue LED backlight which is filtered through a yellow phosphor coating, producing a pseudo white light.
All combined, this allows an LCD display to control the amount of RGB light reaching the surface by culling a backlight, rather than producing colored light in each pixel. Just like AMOLED, LCD displays can either be active or passive matrix devices, but most smartphones are active these days.
This wide variation in the way that light is produced has quite a profound difference to the user experience. Color gamut is often the most talked-about difference between the two display types, with AMOLED providing a greater range of color options than LCD, resulting in more vibrant-looking images.
OLED displays have been known for additional green and blue saturation, as these tend to be the most powerful colors in the sub-pixel arrangement, and very little green is required for white light. Some observers find that this extra saturation produces results that they find slightly unnatural looking. Although color accuracy has improved substantially in the past few years and tends to offer better accuracy for wider color gamuts like DCI-P3 and BT-2020. Despite not possessing quite such a broad gamut, LCD displays typically offer 100% sRGB gamut used by most content and can cover a wide gamut and most of the DCI-P3 color space too.
As we mentioned before, the lack of a backlight and filtering layers weighs in favor of OLED over LCD. LCD displays often suffer from light bleed and a lower contrast ratio as the backlight doesn’t switch off even when pixels are supposed to be black, while OLED can simply switch off its pixels. LCD’s filtering layer also inherently blocks some light and the additional depth means that viewing angles are also reduced compared to OLED.
One downside of AMOLED is that different LEDs have different life spans, meaning that the individual RBG light components eventually degrade at slightly different rates. As well as the dreaded but relatively rare burn-in phenomenon, OLED display color balance can drift very slightly over time, while LED’s single backlight means that color balance remains more consistent across the display. OLED pixels also often turn off and on slower, meaning that the highest refresh rate displays are often LCD. Particularly in the monitor market where refresh rates exceed 120Hz. That said, plenty of OLED smartphones offer 90, 120, and even 144Hz support.
There are some pros and cons to both technologies and some reasonable user preferences between the different color and contrast profiles. Although the prevalence of multiple display modes available in modern smartphones makes this somewhat less of an issue these days. However, the falling production costs and additional benefits of OLED displays have made them a more popular choice than ever across a wide range of price segments. OLED dominates the high-end smartphone and TV spaces owing to its wider color gamut, superior contrast ratio, while still supporting decent refresh rates. Not to mention its flexible characteristics for brand new mobile form factors.
Major display manufacturers, such as LG Display and Samsung Display, are betting big on OLED technology for the future, making major investments into additional production facilities. Particularly when it comes to its use in flexible display technology. The AMOLED panel market is expected to be worth close to $30 billion in 2022, more than double its value in 2017 when this article was first published.
That said, developments in Quantum Dot and mini LED displays are closing the already small performance gap between LCD and OLED, so certainly don’t count LCD out of the race just yet.
In recent years, smartphone displays have developed far more acronyms than ever before with each different one featuring a different kind of technology. AMOLED, LCD, LED, IPS, TFT, PLS, LTPS, LTPO...the list continues to grow.
As if the different available technologies weren"t enough, component and smartphone manufacturers adopt more and more glorified names like "Super Retina XDR" and "Dynamic AMOLED", which end up increasing the potential for confusion among consumers. So let"s take a look at some of these terms used in smartphone specification sheets and decipher them.
There are many display types used in smartphones: LCD, OLED, AMOLED, Super AMOLED, TFT, IPS and a few others that are less frequently found on smartphones nowadays, like TFT-LCD. One of the most frequently found on mid-to-high range phones now is IPS-LCD. But what do these all mean?
LCD means Liquid Crystal Display, and its name refers to the array of liquid crystals illuminated by a backlight, and their ubiquity and relatively low cost make them a popular choice for smartphones and many other devices.
LCDs also tend to perform quite well in direct sunlight, as the entire display is illuminated from behind, but does suffer from potentially less accurate colour representation than displays that don"t require a backlight.
Within smartphones, you have both TFT and IPS displays. TFT stands for Thin Film Transistor, an advanced version of LCD that uses an active matrix (like the AM in AMOLED). Active matrix means that each pixel is attached to a transistor and capacitor individually.
The main advantage of TFT is its relatively low production cost and increased contrast when compared to traditional LCDs. The disadvantage of TFT LCDs is higher energy demands than some other LCDs, less impressive viewing angles and colour reproduction. It"s for these reasons, and falling costs of alternative options, that TFTs are not commonly used in smartphones anymore.Affiliate offer
IPS technology (In-Plane Switching) solves the problem that the first generation of LCD displays experience, which adopts the TN (Twisted Nematic) technique: where colour distortion occurs when you view the display from the side - an effect that continues to crop up on cheaper smartphones and tablets.
The PLS (Plane to Line Switching) standard uses an acronym that is very similar to that of IPS, and is it any wonder that its basic operation is also similar in nature? The technology, developed by Samsung Display, has the same characteristics as IPS displays - good colour reproduction and viewing angles, but a lower contrast level compared to OLED and LCD/VA displays.
According to Samsung Display, PLS panels have a lower production cost, higher brightness rates, and even superior viewing angles when compared to their rival, LG Display"s IPS panels. Ultimately, whether a PLS or IPS panel is used, it boils down to the choice of the component supplier.
This is a very common question after "LED" TVs were launched, with the short answer simply being LCD. The technology used in a LED display is liquid crystal, the difference being LEDs generating the backlight.
One of the highlights from TV makers at the CES 2021 tradeshow, mini-LED technology seemed far removed from mobile devices until Apple announced the 2021 iPad Pro. As the name implies, the technique is based on the miniaturization of the LEDs that form the backlight of the screen — which still uses an LCD panel.
Despite the improvement in terms of contrast (and potentially brightness) over traditional LCD/LED displays, LCD/mini-LEDs still divide the screen into brightness zones — over 2,500 in the case of the iPad and 2021 "QNED" TVs from LG — compared to dozens or hundreds of zones in previous-generation FALD (full-array local dimming) displays, on which the LEDs are behind the LCD panel instead of the edges.
AMOLED stands for Active Matrix Organic Light-Emitting Diode. While this may sound complicated it actually isn"t. We already encountered the active matrix in TFT LCD technology, and OLED is simply a term for another thin-film display technology.
OLED is an organic material that, as the name implies, emits light when a current is passed through it. As opposed to LCD panels, which are back-lit, OLED displays are "always off" unless the individual pixels are electrified.
This means that OLED displays have much purer blacks and consume less energy when black or darker colours are displayed on-screen. However, lighter-coloured themes on AMOLED screens use considerably more power than an LCD using the same theme. OLED screens are also more expensive to produce than LCDs.
Because the black pixels are "off" in an OLED display, the contrast ratios are also higher compared to LCD screens. AMOLED displays have a very fast refresh rate too, but on the downside are not quite as visible in direct sunlight as backlit LCDs. Screen burn-in and diode degradation (because they are organic) are other factors to consider.Affiliate offer
OLED stands for Organic Light Emitting Diode. An OLED display is comprised of thin sheets of electroluminescent material, the main benefit of which is they produce their own light, and so don"t require a backlight, cutting down on energy requirements. OLED displays are more commonly referred to as AMOLED displays when used on smartphones or TVs.
As we"ve already covered, the AM part of AMOLED stands for Active Matrix, which is different from a Passive Matrix OLED (P-OLED), though these are less common in smartphones.
Super AMOLED is the name given by Samsung to its displays that used to only be found in high-end models but have now trickled down to more modestly specced devices. Like IPS LCDs, Super AMOLED improves upon the basic AMOLED premise by integrating the touch response layer into the display itself, rather than as an extra layer on top.
As a result, Super AMOLED displays handle sunlight better than AMOLED displays and also require less power. As the name implies, Super AMOLED is simply a better version of AMOLED. It"s not all just marketing bluster either: Samsung"s displays are regularly reviewed as some of the best around.
The latest evolution of the technology has been christened "Dynamic AMOLED". Samsung didn"t go into detail about what the term means, but highlighted that panels with such identification include HDR10+ certification that supports a wider range of contrast and colours, as well as blue light reduction for improved visual comfort.
In the same vein, the term "Fluid AMOLED" used by OnePlus on its most advanced devices basically highlights the high refresh rates employed, which results in more fluid animations on the screen.Affiliate offer
Resolution describes the number of individual pixels (or points) displayed on the screen and is usually presented for phones by the number of horizontal pixels — vertical when referring to TVs and monitors. More pixels on the same display allow for more detailed images and clearer text.
Speaking of pixel density, this was one of Apple"s highlights back in 2010 during the launch of the iPhone 4. The company christened the LCD screen (LED, TFT, and IPS) used in the smartphone as "Retina Display", thanks to the high resolution of the panel used (960 by 640 pixels back then) in its 3.5-inch display.
With the iPhone 11 Pro, another term was introduced to the equation: "Super Retina XDR". Still using an OLED panel (that is supplied by Samsung Display or LG Display), the smartphone brings even higher specs in terms of contrast - with a 2,000,000:1 ratio and brightness level of 1,200 nits, which have been specially optimized for displaying content in HDR format.
As a kind of consolation prize for iPhone XR and iPhone 11 buyers, who continued relying on LCD panels, Apple classified the display used in the smartphones with a new term, "Liquid Retina". This was later applied also to the iPad Pro and iPad Air models, with the name defining screens that boast a high range and colour accuracy, at least based on the company"s standards.
TFT(Thin Film Transistor) - a type of LCD display that adopts a thin semiconductor layer deposited on the panel, which allows for active control of the colour intensity in each pixel, featuring a similar concept as that of active-matrix (AM) used in AMOLED displays. It is used in TN, IPS/PLS, VA/PVA/MVA panels, etc.
LTPS(Low Temperature PolySilicon) - a variation of the TFT that offers higher resolutions and lower power consumption compared to traditional TFT screens, based on a-Si (amorphous silicon) technology.
IGZO(Indium Gallium Zinc Oxide) - a semiconductor material used in TFT films, which also allows higher resolutions and lower power consumption, and sees action in different types of LCD screens (TN, IPS, VA) and OLED displays
LTPO(Low Temperature Polycrystaline Oxide) - a technology developed by Apple that can be used in both OLED and LCD displays, as it combines LTPS and IGZO techniques. The result? Lower power consumption. It has been used in the Apple Watch 4 and the Galaxy S21 Ultra.
Among televisions, the long-standing featured technology has always been miniLED - which consists of increasing the number of lighting zones in the backlight while still using an LCD panel. There are whispers going around that smartphones and smartwatches will be looking at incorporating microLED technology in their devices soon, with it being radically different from LCD/LED displays as it sports similar image characteristics to that of OLEDs.
As previously stated, OLED/AMOLED screens have the advantage of a varied contrast level, resulting from individual brightness control for the pixels. Another result of this is the more realistic reproduction of black, as well as low power consumption when the screen shows off dark images - which has also helped to popularize dark modes on smartphones.
In the case of LCD displays, the main advantage lies in the low manufacturing cost, with dozens of players in the market offering competitive pricing and a high production volume. Some brands have taken advantage of this feature to prioritize certain features - such as a higher refresh rate - instead of adopting an OLED panel, such as the Xiaomi Mi 10T.
AMOLED (active-matrix organic light-emitting diode, OLED display device technology. OLED describes a specific type of thin-film-display technology in which organic compounds form the electroluminescent material, and active matrix refers to the technology behind the addressing of 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 passive-matrix OLED operation.
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.
AMOLED was developed in 2006. Samsung SDI was one of the main investors in the technology, and many other display companies were also developing it. One of the earliest consumer electronics products with an AMOLED display was the BenQ-Siemens S88 mobile handsetiriver Clix 2 portable media player.Nokia N85 followed by the Samsung i7110 - both Nokia and Samsung Electronics were early adopters of this technology on their smartphones.
Manufacturers have developed in-cell touch panels, integrating the production of capacitive sensor arrays in the AMOLED module fabrication process. In-cell sensor AMOLED fabricators include AU Optronics and Samsung. Samsung has marketed its version of this technology as "Super AMOLED". Researchers at DuPont used computational fluid dynamics (CFD) software to optimize coating processes for a new solution-coated AMOLED display technology that is competitive in cost and performance with existing chemical vapor deposition (CVD) technology. Using custom modeling and analytic approaches, Samsung has developed short and long-range film-thickness control and uniformity that is commercially viable at large glass sizes.
The amount of power the display consumes varies significantly depending on the color and brightness shown. As an example, one old QVGA OLED display consumes 0.3 watts while showing white text on a black background, but more than 0.7 watts showing black text on a white background, while an LCD may consume only a constant 0.35 watts regardless of what is being shown on screen.
AMOLED displays may be difficult to view in direct sunlight compared with LCDs because of their reduced maximum brightness.Super AMOLED technology addresses this issue by reducing the size of gaps between layers of the screen.PenTile technology is often used for a higher resolution display while requiring fewer subpixels than needed otherwise, sometimes resulting in a display less sharp and more grainy than a non-PenTile display with the same resolution.
The organic materials used in AMOLED displays are very prone to degradation over a relatively short period of time, resulting in color shifts as one color fades faster than another, image persistence, or burn-in.
As of 2010, demand for AMOLED screens was high and, due to supply shortages of the Samsung-produced displays, certain models of HTC smartphones were changed to use next-generation LCD displays from the Samsung-Sony joint-venture SLCD in the future.
Flagship smartphones sold in 2020 and 2021 used either a Super AMOLED. Super AMOLED displays, such as the one on the Samsung Galaxy S21+ / S21 Ultra and Samsung Galaxy Note 20 Ultra have often been compared to IPS LCDs, found in phones such as the Xiaomi Mi 10T, Huawei Nova 5T, and Samsung Galaxy A20e.ABI Research, the AMOLED display found in the Motorola Moto X draws just 92 mA during bright conditions and 68 mA while dim.
"Super AMOLED" is a marketing term created by Samsung for an AMOLED display with an integrated touch screen digitizer: the layer that detects touch is integrated into the display, rather than overlaid on top of it and cannot be separated from the display itself. The display technology itself is not improved. According to Samsung, Super AMOLED reflects one-fifth as much sunlight as the first generation AMOLED.One Glass Solution (OGS).
Future displays exhibited from 2011 to 2013 by Samsung have shown flexible, 3D, transparent Super AMOLED Plus displays using very high resolutions and in varying sizes for phones. These unreleased prototypes use a polymer as a substrate removing the need for glass cover, a metal backing, and touch matrix, combining them into one integrated layer.

Tried and trusted TFT technology works by controlling brightness in red, green and blue sub-pixels through transistors for each pixel on the screen. The pixels themselves do not produce light; instead, the screen uses a backlight for illumination.
By contrast the Active Matrix OLED (AMOLED) display requires no backlight and can light up or turn off each of their pixels independently. As the name suggests, they are made of organic material.
An AMOLED display has many other benefits which make it a superior looking display including exceptional vieiwng angles and a display that looks practically black when it is switched off.
So, why use a TFT display? Well, it is a mature technology meaning the manufacturing processes are efficient, yields high and cost much lower than AMOLED.
TFT displays also have a much longer lifespan than AMOLED displays and are available in a far greater range of standard sizes, which can be cut down to fit a space restricted enclosure for a relatively low cost adder.
LCD (Liquid Crystal Display) displays consist of a matrix of Liquid Crystals. Liquid Crystals do not emit light themselves and are reliant on some form of back-light to illuminate the whole display. As a result LCD displays can be very visible in direct sunlight.
IPS-LCDs provide a superior viewing angle and better color reproduction than non IPS-LCDs due to the layout of the LCD"s themselves. This has become a common display type for mid-range to high-end phones.
OLED & AMOLED utilizes "organic" LEDs which emits light and in the majority of cases does away with the need for the back-light of an LCD display resulting in a potentially thinner panel.
They consume less power as opposed to LCDs which always have the back-light on. When a pixel is "black" on a OLED/AMOLED display the pixel is truly off.
Higher refresh rate displays are the trend in 2020. We saw flagship coming with 90Hz and 120Hz refresh rate displays. And now even mid-range devices come with this feature. Hence, let’s do an IPS LCD 120Hz Refresh Rate VS AMOLED 60Hz comparison. But first, let’s start with the basics. What is a refresh rate? Well, it is the rate at which a display refreshes. Standard displays come with a 60Hz refresh rate meaning the display will be refreshed 60 times per second. 90Hz refresh rate means the display refreshes 90 times per second and vice versa for 120Hz refresh rate.
A higher refresh rate essentially means a smoother experience while scrolling or play games. 90Hz is smoother than 60Hz, and 120Hz is smoother of all. We also have 144Hz refresh rate displays which you will find on very few smartphones. But finding 90hz and 120Hz refresh rate smartphones is easy. On the other hand, AMOLED panels are beneficial when the battery is concerned. The blacks are deeper. The colors are saturated, which will be a delight for multi-media usage.
There are usually two choices in the mid-range and upper mid-range market. One is with an LCD panel with a 90Hz or 120Hz refresh rate. And the other one is having an AMOLED panel with a 60Hz refresh rate. For example, POCO X3 NFC and Realme 7 Pro comes at a similar price range. The POCO X3 NFC is having a 120Hz refresh rate LCD display. On the other hand, Realme 7 Pro has an AMOLED display. Most probably, if you game on your smartphone then you would go for the higher refresh rate. But it will be no good.
AMOLED or Active Matrix Organic Light-Emitting Diode display is known for its punchy colors. AMOLED display work by the rule “pixel-by-pixel.” By pixel by pixel, You will usually get colorful images when compared to an LCD panel. One of the areas where AMOLED really shines against the LCD panels is the black color. You can easily tell if a display is using AMOLED or LCD technology just by seeing the black color.
On AMOLED displays, blacks are deeper. They are near to perfect blacks. It leads to a better battery backup as well. AMOLED technology also allows you to get an in-display fingerprint scanner. However, it will be slower than a side-mounted or rear-mounted one. Hence, AMOLED really has much more pros than an LCD with a higher refresh rate. But nothing is perfect, and hence AMOLED has some known issues, you might want to know.
Well, you may come up with a lot of news of AMOLED devices having a burned display. Pixel-by-pixel illumination may result in burn-in after some time of usage. And also if you are into photography, an AMOLED display might not be the best for you. As I said earlier, AMOLED produces “Colorful” images. It is pleasing to the eyes especially when watching movies. However, a photographer always wants the correct colors. Hence, this might be a con for photographers.
This article is aimed especially at a higher refresh rate display VS AMOLED, and not just IPS LCD VS AMOLED. So I will not talk about more the technology but I thought it is my duty to inform you about some of the cons of AMOLED as-well.
In a nutshell, AMOLED is a good choice for the majority, especially in the mid-range market. In flagship devices, you are already getting both i.e a higher refresh rate and AMOLED panel. Hence, my suggestion is to go for an AMOLED (60Hz) over LCD with a higher refresh rate in the mid-range and upper-midrange market.
If AMOLED + Higher refresh rate is not available in your budget, then try to find out smartphones with AMOLED panels with higher-touch sampling rates. iPhones don’t come with a higher refresh rate but they still seem more responsive, right? Well, they have a higher-touch sampling rate which reduces the touch lag. You can find such smartphones in the upper mid-range market like the Xiaomi Mi 10 Lite 5G. It came with an AMOLED display and a 240Hz touch sampling rate.
Estamos en un momento en el que damos mucha más importancia a la pantalla de los teléfonos inteligentes que a cualquier otra especificación. Además, el tamaño de la pantalla parece haber quedado relegado, ya que los usuarios están más interesados en la calidad real que proporciona la pantalla que en sus pulgadas.
Pasamos muchas horas delante de ellas: no nos vale cualquier cosa. Así pues, veamos por medio de un breve repaso los distintos tipos de pantalla que podemos encontrar en el mercado. Con sus pros y contras.
Vamos con un puñado de siglas: AMOLED es el acrónimo de Active Matrix Organic Light-Emitting Diode. Las pantallas AMOLED usan materiales orgánicos que emiten luz cuando se aplica electricidad.
Los AMOLED permiten mostrar imágenes brillantes, delgadas, flexibles y eficientes. Las pantallas AMOLED están siempre apagadas a menos que los píxeles individuales estén eléctricamente excitados. Esto significa que las pantallas AMOLED tienen negros mucho más puros y consumen menos energía cuando se muestran colores negros o más oscuros en la pantalla. Además, dado que son muy flexibles, pueden doblarse.
Las pantallas AMOLED son relativamente caras de producir y están muy saturadas. Sin embargo, las pantallas AMOLED son vibrantes y son mejores para la reproducción del color.
LCD significa pantalla de cristal líquido. Las pantallas LCD están formadas por una serie de cristales líquidos que se iluminan con una luz de fondo. Requieren menos energía y, por lo tanto, son muy populares en dispositivos portátiles como teléfonos móviles. Las pantallas LCD también tienden a funcionar bastante bien a la luz solar directa, ya que la iluminación del panel viene por detrás. Son ideales para muchos tipos de teléfonos inteligentes.
TFT significa "Transductor de película delgada", una versión avanzada de LCD que usa una matriz activa. La matriz activa significa que cada píxel está conectado a un transistor y condensador individualmente. La ventaja de tener pantallas TFT es que tienen una alta relación de contraste y un bajo costo de producción, lo que reduce el precio de su dispositivo. Sin embargo, no tienen buenos ángulos de visión e impresionante reproducción del color.
IPS significa In-Plane Switching (cambio en el plano) y es una mejora adicional en TFT LCD. De hecho, es un tipo específico de panel LCD que se creó para mejorar el TFT-LCD. La forma en que los cristales se excitan eléctricamente sobre ellos es diferente y la orientación de la matriz de cristal se rota. Este cambio de orientación mejora los ángulos de visión, la relación de contraste y la reproducción del color. El consumo de energía también se reduce en comparación con las pantallas LCD TFT. Debido a que los LCD IPS tienden a ser mejores que los LCD TFT, también son más caros cuando se los coloca en un teléfono inteligente.
La introducción de IPS redujo en gran medida muchas deficiencias de TFT-LCD. La reproducción del color mejoró mucho, el ángulo de visión aumentó y el tiempo de respuesta de la pantalla mejoró drásticamente.
IPS se ha convertido en una mejor opción para los jugadores debido a su tiempo de respuesta mínimo. Esto, a su vez, nos brinda una mejor respuesta táctil, mucho mejor que AMOLED y pantallas TFT-LCD normales.
Los paneles son más delgados: permite dispositivos más delgados. Para un grosor idéntico al de AMOLED, los fabricantes de dispositivos IPS deben esforzarse más y sacrificarse.
Baja vida útil: los paneles OLED y AMOLED se degradan más rápido que el IPS LCD. La mayoría de las estimaciones indican 14,000 horas como tiempo de vida del panel. IPS fácilmente tiene una vida útil de hasta 60,000 horas. En el caso de los teléfonos inteligentes no es un problema importante. 14,000 horas es equivalente a 8 horas diarias durante 5 años. Pero en general, el color azul es el primero que comienza a degradarse en AMOLED. Los recientes avances en AMOLED han logrado una vida útil de 62,000 horas para el azul y 198,000 para el verde.
Color blanco intenso: un alto brillo, en comparación con AMOLED. La diferencia de intensidad es claramente visible, dejando al oponente más cerca de gris o blanco.
Una pantalla IPS, también conocida como panel de conmutación en el plano, es un tipo de tecnología de visualización de alta calidad que generalmente se implementan en monitores, tabletas y teléfonos inteligentes de computadora y portátiles de alto rendimiento.
IPS ofrece una mejor experiencia de usuario debido a su ángulo más amplio y calidad de color mejorada, características de visualización que han evolucionado bastante con el tiempo desde que se introdujeron las pantallas LCD con efecto TN y se utilizaron de forma ubicua en la década de 1990.
Las tabletas y teléfonos inteligentes de alto rendimiento tienen esta tecnología de pantallas IPS porque estos productos nacieron para estas funciones: ver pelis, chatear por video, y almacenar y editar fotos. Las características mejoradas de la tecnología de ángulo y color proporcionan una mejor experiencia general para el usuario.
Tecnología como la Super IPS+ del nuevo Zenfone 4 rinden perfectamente bajo luz directa gracias a su límite lumínico de 600 nits, a que sumar la tecnología Splendid —que es capaz de ajustar la temperatura del color según las condiciones de la luz ambiente—
Y los profesionales creativos también se benefician de un monitor IPS: una pantalla IPS+ proporciona una gama de colores más amplia y mayores ángulos de visión, con los que obtener una mayor precisión estética y resultados más coherentes. Dicho de otro modo: lo que ven es una traducción sin artificios.

AMOLED (Active Matrix Organic Light Emitting Diode) and TFT (Thin Film Transistor) are the two types of displays that are used in mobile phones. TFT is actually a process of producing the displays and is used even by AMOLED but for most purposes, TFT is used to refer to LCD displays. The difference between them is the material as AMOLED uses organicmaterials, mainly carbon, while TFT does not.
There are differences between the two that are quite tangible. For starters, AMOLED generates its own light rather than relying on a backlight like a TFT-LCD does. This consequently means that AMOLED displays are much thinner than LCD displays; due to the absence of a backlight. It also results in much better colors than a TFT is capable of producing. As each pixel’s color and light intensity can be regulated independently and no light seeps from adjacent pixels. A side by side comparison of the two displays with the same picture should confirm this. Another effect of the lack of a backlight is the much lower power consumption of the device. This is very desirable when it comes to mobile phones where every single feature competes for the limited capacity of the battery. As the screen is on 90% of the time that the device is being used, it is very good that AMOLED displays consume less. Just how much of a difference is not very fixed though as it really depends on the color and intensity of the image. Having a black background with white text consumes much less energy than having black text on a white background.
The biggest disadvantage that AMOLED has is the shorter lifespan of the screen compared to TFT. Each pixel in the display degrades with each second that it is lit and even more so the brighter it is. Â Despite improvements on the lifetime of AMOLED displays, AMOLED still only lasts a fraction of the lifetime of a TFT display. With that said, an AMOLED display is able to outlast the usable lifetime of the device before parts of it start to degrade.
The main hindrance to the massive adaptation of AMOLED is the low production numbers. TFT has been in production for much longer and the infrastructure is already there to meet the demands.
