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.
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.
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.
Samsung came up with its unique 18:5:9 AMOLED display for the Galaxy S8. LG picked up its old trusted IPS LCD unit for the G6’s display. These display units have been familiar to the usual Indian smartphone buyer. Honor, on the other hand, has just unveiled the new Honor 8 Pro for the Indian market that ships with an LTPS LCD display. This has led to wonder how exactly is this technology different from the existing ones and what benefits does it give Honor to craft its flagship smartphone with. Well, let’s find out.
The LCD technology brought in the era of thin displays to screens, making the smartphone possible in the current world. LCD displays are power efficient and work on the principle of blocking light. The liquid crystal in the display unit uses some kind of a backlight, generally a LED backlight or a reflector, to make the picture visible to the viewer. There are two kinds of LCD units – passive matrix LCD that requires more power and the superior active matrix LCD unit, known to people as Thin Film Transistor (TFT) that draws less power.
The early LCD technology couldn’t maintain the colour for wide angle viewing, which led to the development of the In-Plane Switching (IPS) LCD panel. IPS panel arranges and switches the orientation of the liquid crystal molecules of standard LCD display between the glass substrates. This helps it to enhance viewing angles and improve colour reproduction as well. IPS LCD technology is responsible for accelerating the growth of the smartphone market and is the go-to display technology for prominent manufacturers.
The standard LCD display uses amorphous Silicon as the liquid for the display unit as it can be assembled into complex high-current driver circuits. This though restricts the display resolution and adds to overall device temperatures. Therefore, development of the technology led to replacing the amorphous Silicon with Polycrystalline Silicon, which boosted the screen resolution and maintains low temperatures. The larger and more uniform grains of polysilicon allow faster electron movement, resulting in higher resolution and higher refresh rates. It also was found to be cheaper to manufacture due to lower cost of certain key substrates. Therefore, the Low-Temperature PolySilicon (LTPS) LCD screen helps provide larger pixel densities, lower power consumption that standard LCD and controlled temperature ranges.
The AMOLED display technology is in a completely different league. It doesn’t bother with any liquid mechanism or complex grid structures. The panel uses an array of tiny LEDs placed on TFT modules. These LEDs have an organic construction that directly emits light and minimises its loss by eradicating certain filters. Since LEDs are physically different units, they can be asked to switch on and off as per the requirement of the display to form a picture. This is known as the Active Matrix system. Hence, an Active Matrix Organic Light Emitting Diode (AMOLED) display can produce deeper blacks by switching off individual LED pixels, resulting in high contrast pictures.
The honest answer is that it depends on the requirement of the user. If you want accurate colours from your display while wanting it to retain its vibrancy for a longer period of time, then any of the two LCD screens are the ideal choice. LTPS LCD display can provide higher picture resolution but deteriorates faster than standard IPS LCD display over time.
An AMOLED display will provide high contrast pictures any time but it too has the tendency to deteriorate faster than LCD panels. Therefore, if you are after greater picture quality, choose LTPS LCD or else settle for AMOLED for a vivid contrast picture experience.
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.
Cutting edge display technology has been a central feature of flagship smartphones in recent years. The LG V30 arrived late last year with yet another innovation in screen tech: new panel type called P-OLED. With Samsung still marketing its Super AMOLED and Infinity Display technology, and some other manufacturers moving away from the tried and tested IPS LCD, there’s never been more choice for display panel tech in the smartphone market.
P-OLED isn’t exactly the new kid on the block, but the technology is just starting to appear in a number of flagship handsets. We’ve already seen how LG Display’s P-OLED stacks up against Samsung’s AMOLED,but what about the common IPS LCD display technology? That’s what we aim to find out in this P-OLED vs IPS LCD breakdown.
The common LCD stands for Liquid Crystal Display, while IPS stands for “in-plane switching”. The latter controlls the crystal elements in the display’s RGB sub-pixel layout. IPS replaced twisted nematic field effect (TN) as the technology of choice for LCD in the 90s, and is what you’ll find in all LCD-based smartphone panels.
The technology features a polarized backlight passing through the liquid crystals, in front of red, green, and blue color filters for each sub-pixel. With IPS, a current is used to create an electric field parallel to the plate, which twists the polarized crystal and further shifts the polarity of the light. A second polarizer then filters out the light based on its polarity. The more light passes through the second polarizer, the brighter the associated RGB sub-pixel will be.
Each sub-pixel is connected up to a thin-film transistor active matrix, which drives the panel’s brightness and color without consuming as much current as an outdated passive matrix display. Using different TFT materials and production techniques can alter the driving properties of the display and alter the transistor sizes, which affects properties such as brightness, viewing angles, and color gamut. Hence why you’ll find a variety of different naming schemes for IPS LCD display, including Super IPS, Super LCD5, and others.
The makeup of the backlight can vary between LCD panels too, as the white light has to be created from another group of colors. The light source can be made up of LEDs or an electroluminescent panel (ELP), among others, each of which can offer a slightly different white tint and varying degrees of even light across their surface.
OLED technology has been the major rival to LCD in the smartphone market for what seems like forever. Samsung’s AMOLED technology has powered generations of the top selling Android flagship. Plastic-OLED (or P-OLED) is simply the latest iteration of this technology, primarily designed to enable new and interesting form factors.
Compared with the numerous layers of an LCD display, P-OLED is considerably less complicated looking. The key component is a Light Emitting Diode (LED). So rather than relying on a universal backlight, each sub-pixel is capable of producing its own red, green, or blue light, or being shut-off completely. The O part in OLED stands for organic, which is the compound type that lights up when current is applied.
To drive this current, the TFT matrix is used in a very similar way to LCD. Although this time the current is used to produce the light rather than twist the polarizing crystals. As this is an active matrix TFT, Samsung chose to call its OLED panels AMOLED. P-OLED shouldn’t be confused with the outdated PMOLED technology, which stands for passive matrix and isn’t used in any modern pieces of high-end display tech.
So where does the plastic element come in? Well it’s simply the material used as the back substrate on which the TFT and OLED components are placed. Historically, this has been made from glass but using a plastic substrate makes the display more malleable and flexible. It’s important to note however, that switching over to a plastic substrate requires new materials for the TFT plane that can withstand the manufacturing temperatures, while still providing sufficient electron mobility and current for the LEDs.
The two display technologies have their own pros and cons in terms of viewing quality, but plastic OLED has a trick up its sleeve that LCD can’t yet match — flexibility.
Although the very top of a smartphone display will likely feature a protective glass layer, such as Gorilla Glass, the underlying plastic substrate layer does offer some additional shock absorption. This means that it’s less likely that the TFT layer will break on dropping, helping to preserve functionality even if the top layer cracks.
It’s worth stating that flexible LCD alternatives are in development. Japan Display showcased its low-cost flexible LCD technology in early 2017 and other companies are working on Organic LCD and similar ideas. However, the trick is still to match flexible OLED for pixel density and resolution, color gamut, and production yield. So it’s likely to be a while before we see competing flexible LCD products.
Unfortunately, there’s no definitive superior technology between IPS LCD and P-OLED. There are too many variables beyond the basic display type that determine the quality of the viewing experience. These include sub-pixel layouts and manufacturing materials.
No two IPS LCD manufacturers are necessarily alike, and even P-OLED will undoubtedly go through generational revisions over the next few years and continue to improve performance. Furthermore, new advances in LCD technology, including Quantum Dot, WRGB, and others, keep reinvigorating the already well-refined technology.
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.
If you’ve ever begun searching for a new computer screen, chances are you’ve probably come across the term IPS. It’s at this point that you may be asking yourself, what is an IPS monitor? And how do I know if an IPS monitor is right for me?
Below we’ll take a look at how IPS, TN, and VA monitors affect screen performance and do some handy summaries of strengths, weaknesses, and best-case uses for each type of panel technology.
IPS monitors or “In-Plane Switching” monitors, leverage liquid crystals aligned in parallel to produce rich colors. IPS panels are defined by the shifting patterns of their liquid crystals. These monitors were designed to overcome the limitations of TN panels. The liquid crystal’s ability to shift horizontally creates better viewing angles.
IPS monitors continue to be the display technology of choice for users that want color accuracy and consistency. IPS monitors are really great when it comes to color performance and super-wide viewing angles. The expansive viewing angles provided by IPS monitors help to deliver outstanding color when being viewed from different angles. One major differentiator between IPS monitors and TN monitors is that colors on an IPS monitor won’t shift when being viewed at an angle as drastically as they do on a TN monitor.
IPS monitor variations include S-IPS, H-IPS, e-IPS and P-IPS, and PLS (Plane-to-Line Switching), the latter being the latest iteration. Since these variations are all quite similar, they are all collectively referred to as “IPS-type” panels. They all claim to deliver the major benefits associated with IPS monitors – great color and ultra-wide viewing angles.
When it comes to color accuracy, IPS monitors surpass the performance of TN and VA monitors with ease. While latest-gen VA technologies offer comparative performance specs, pro users still claim that IPS monitors reign supreme in this regard.
Another important characteristic of IPS monitors is that they are able to support professional color space technologies, such as Adobe RGB. This is due to the fact that IPS monitors are able to offer more displayable colors, which help improve color accuracy.
In the past, response time and contrast were the initial weakness of IPS technology. Nowadays, however, IPS monitor response times have advanced to the point where they are even capable of satisfying gamers, thus resulting in a rising popularity in IPS monitors for gaming.
With regard to gaming, some criticisms IPS monitors include more visible motion blur coming as a result of slower response times, however the impact of motion blur will vary from user to user. In fact, mixed opinions about the “drawbacks” of IPS monitor for gaming can be found all across the web. Take this excerpt from one gaming technology writer for example: “As for pixel response, opinions vary. I personally think IPS panels are quick enough for almost all gaming. If your gaming life is absolutely and exclusively about hair-trigger shooters, OK, you’ll want the fastest response, lowest latency LCD monitor. And that means TN. For the rest of us, and certainly for those who place even a modicum of importance on the visual spectacle of games, I reckon IPS is clearly the best panel technology.” Read the full article here.
IPS monitors deliver ultra-wide 178-degree vertical and horizontal viewing angles. Graphic designers, CAD engineers, pro photographers, and video editors will benefit from using an IPS monitor. Many value the color benefits of IPS monitors and tech advances have improved IPS panel speed, contrast, and resolution. IPS monitors are more attractive than ever for general desktop work as well as many types of gaming. They’re even versatile enough to be used in different monitor styles, so if you’ve ever compared an ultrawide vs. dual monitor setup or considered the benefits of curved vs. flat monitors, chances are you’ve already come into contact with an IPS panel.
TN monitors, or “Twisted Nematic” monitors, are the oldest LCD panel types around. TN panels cost less than their IPS and VA counterparts and are a popular mainstream display technology for desktop and laptop displays.
Despite their lower perceived value, TN-based displays are the panel type preferred by competitive gamers. The reason for this is because TN panels can achieve a rapid response time and the fastest refresh rates on the market (like this 240Hz eSports monitor). To this effect, TN monitors are able to reduce blurring and screen tearing in fast-paced games when compared to an IPS or VA panel.
These high-end VA-type monitors rival IPS monitors as the best panel technology for professional-level color-critical applications. One of the standout features of VA technology is that it is particularly good at blocking light from the backlight when it’s not needed. This enables VA panels to display deeper blacks and static contrast ratios of up to several times higher than the other LCD technologies. The benefit of this is that VA monitors with high contrast ratios can deliver intense blacks and richer colors.
There is another type of panel technology that differs from the monitor types discussed above and that is OLED or “Organic Light Emitting Diode” technology. OLEDs differ from LCDs because they use positively/negatively charged ions to light up every pixel individually, while LCDs use a backlight, which can create an unwanted glow. OLEDs avoid screen glow (and create darker blacks) by not using a backlight. One of the drawbacks of OLED technology is that it is usually pricier than any of the other types of technology explained.
When it comes to choosing the right LCD panel technology, there is no single right answer. Each of the three primary technologies offers distinct strengths and weaknesses. Looking at different features and specs helps you identify which monitor best fits your needs.
IPS monitors offer the greatest range of color-related features and remain the gold standard for photo editing and color-critical pro uses. Greater availability and lower prices make IPS monitors a great fit for anyone who values outstanding image quality.
LCD or “Liquid Crystal Display” is a type of monitor panel that embraces thin layers of liquid crystals sandwiched between two layers of filters and electrodes.
While CRT monitors used to fire electrons against glass surfaces, LCD monitors operate using backlights and liquid crystals. The LCD panel is a flat sheet of material that contains layers of filters, glass, electrodes, liquid crystals, and a backlight. Polarized light (meaning only half of it shines through) is directed towards a rectangular grid of liquid crystals and beamed through.
Note: When searching for monitors you can be sure to come across the term “LED Panel” at some point or another. An LED panel is an LCD screen with an LED – (Light Emitting Diode) – backlight. LEDs provide a brighter light source while using much less energy. They also have the ability to produce white color, in addition to traditional RGB color, and are the panel type used in HDR monitors.
Early LCD panels used passive-matrix technology and were criticized for blurry imagery. The reason for this is because quick image changes require liquid crystals to change phase quickly and passive matrix technology was limited in terms of how quickly liquid crystals could change phase.
As a result, active-matrix technology was invented and transistors (TFTs) began being used to help liquid crystals retain their charge and change phase more quickly.
Thanks to active-matrix technology, LCD monitor panels were able to change images very quickly and the technology began being used by newer LCD panels.

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.

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.

We start with LCD screens. This technology is what we can usually find in those terminals, since they are cheaper to manufacture and reduce costs when producing mobile devices. In this case we are talking about liquid crystal panels in which the pixels can modify a light source that reaches them to show the different colors on the screens.
In addition, this type of display is divided into two other main ones, as is the case with IPS LCD and TFT LCD panels. The positive side of these IPS (In-Plane Switching) panels is that they are capable of achieving a very high quality representation of color, contrast and viewing angles. In addition to reducing the energy consumption of smartphones compared to other types. On the part of TFT LCD screens, their main advantage over the rest is that the manufacturing cost is quite optimal.
OLED screens are very present today in a large part of high-end mobiles. And it is that this technology uses the general backlighting of the pixel panel, this means that its screens have a light-emitting diode for each pixel. So each pixel will be illuminated separately, giving a series of unique color, contrast and brightness characteristics. And as we will also see later in the world of AMOLED screens, blacks are also seen more and the image contrast is much better appreciated.
AMOLED technology, an acronym for Active Matrix Organic Light-Emitting Diode, which uses organic materials that emit light when electricity is applied. In addition, it is important to emphasize that it is based on OLED technology, although it cannot display the pure black tones of OLED panels.
Mobile devices that have this technology on their screens will be able to show us bright, thin, flexible and efficient images. A striking point of this technology is that it illuminates each pixel only when activated electronically, that is, AMOLED screens are always off unless individual pixels are turned on.
Super AMOLED screens arrived with the intention of replacing the original AMOLED ones. These new panels have less thickness, more powerful brightness, purer colors, better viewing angles and lower power consumption. Therefore, as a result, we find a quite important improvement in these screens, which will offer us sharper, purer and more colorful images with reduced battery consumption.
Keep in mind that saturation on AMOLED and OLED screens can make us more tired. Although, these screens will require less energy and are capable of providing us with a much more intense black color since they do not receive any type of backlight.
Another key difference is that OLED and AMOLED panels have higher degradation than IPS LCD screens. It is estimated that these first two have a maximum life of 14,000 hours, while the IPS can easily have a useful life of up to 60,000 hours. In addition, we will detail other changes later that will help you choose a final winner among these three types of panels.
Although, in this case, the brightness offered by OLED and AMOLED panels is lower compared to LCD screens. The difference in intensity will be visible, leaving the opponent closer to gray or white. In any case, this will not be one of the key points to take into account.
Here is the main feature in which these types of technology differ. An aspect for which we can opt more or less for one panel than for another. In the case of AMOLED and OLED screens, the image we see will take the whiter colors towards slightly yellowish tones. While IPS LCD screens will take the white color to a more realistic tone . The fact that AMOLED panels are more saturated entails an increase in color temperature, but also more vivid and striking colors.
In this case, the AMOLED and OLED panels show a more saturated image , which leads us to have a temperature with more orange tones. Returning to the same thing, an IPS LCD screen manages to show us more realistic image results than its two opponents. Although it is true that in the first two we will have a more vivid image
And it is that, as we have already been warning you, the cheapest in the world of smartphones are LCD screens. Although, we have also seen that they offer us a worse quality. In the case of OLEDs, they are somewhere in between, as they are not as cheap or as expensive as AMOLEDs. Well, this last type of technology is the one that will cost us the most money to repair or replace in case the mobile display is completely broken.
Basically, because each type of screen will offer us some benefits or others, as well as points against. So it is clear that there is no clear answer from the beginning, as we would like. Their respective advantages are striking, although in the case of OLED screens and their AMOLED variant , it is clear that they consume less energy and have a fairly good resolution, showing very vivid colors.
However, it has already become clear to us that the type of LCD panel is cheaper and, after all, they are the classic format, although the battery of the smartphone that has this display will last less. Therefore, each type has its pros and cons, as we have seen, so the final choice will depend on each user, depending on the tastes and the money we want to spend.
In any case, if what you are looking for is a screen that shows us very vivid colors , your best option will be a mobile with an OLED or AMOLED panel. On the other hand, if you want a greater verisimilitude in color, an IPS LCD screen will be the one that best suits your tastes. So, finally, everything will depend on the tastes of each person and their budget.
