tft lcd screen vs super amoled brands
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.
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.
This rise of small, powerful components has also led to significant developments in display technology. The most recent of which, AMOLED, is now the main competitor for the most common display used in quality portable electronics – the TFT–LCD IPS (In-Plane Switching) display. As more factories in the Far East begin to produce AMOLED technology, it seems likely we will enter a battle of TFT IPS versus AMOLED, or LCD vs LED. Where a large percentage of a product’s cost is the display technology it uses, which provides best value for money when you’re designing a new product?
TFT IPSdisplays improved on previous TFT LCD technology, developed to overcome limitations and improve contrast, viewing angles, sunlight readability and response times. Viewing angles were originally very limited – so in-plane switching panels were introduced to improve them.
Modern TFT screens can have custom backlights turned up to whatever brightness that their power limit allows, which means they have no maximum brightness limitation. TFT IPS panels also have the option for OCA bonding, which uses a special adhesive to bond a touchscreen or glass coverlens to the TFT. This improves sunlight readability by preventing light from bouncing around between the layers of the display, and also improves durability without adding excess bulk; some TFT IPS displays now only measure around 2 mm thick.
AMOLED technology is an upgrade to older OLED technology. It uses organic compounds that emit light when exposed to electricity. This means no backlight, which in turn means less power consumption and a reduction in size. AMOLED screens tend to be thinner than TFT equivalents, often produced to be as thin as 1 mm. AMOLED technology also offers greater viewing angles thanks to deeper blacks. Colours tend to be greater, but visibility in daylight is lower than IPS displays.
As manufacturers increasingly focus on smaller devices, such as portable smartphones and wearable technology, the thinness and high colour resolution of AMOLED screens have grown desirable. However, producing AMOLED displays is far more costly as fewer factories offer the technology at a consistent quality and minimum order quantities are high; what capacity there is is often taken up the mobile phone market Full HD TFT IPS displays have the advantage of being offered in industry standard sizes and at a far lower cost, as well as offering superior sunlight visibility.
The competition between displays has benefitted both technologies as it has resulted in improvements in both. For example, Super AMOLED, a marketing brand by Samsung, involves the integration of a touchscreen layer inside the screen, rather than overlaid on it. The backlight in TFT technology means they can never truly replicate the deep blacks in AMOLED, but improvements have been made in resolution to the point where manufacturers like Apple have been happy to use LCD screens in their smartphones, even as they compete with Samsung’s Super AMOLED.
Aside from smartphones, many technologies utilise displays to offer direct interaction with customers. To decide whether TFT LCD will survive the rise of AMOLED technology, we must first recap the advantages of LCD. The backlit quality means that whites are bright and contrast is good, but this will wear down a battery faster than AMOLED. Additionally, cost is a significant factor for LCD screens. They are cheaper, more freely available and are offered in industry standard sizes so can be ordered for new products without difficulty.
It seems hard to deny that AMOLED will someday become the standard for mobile phones, which demand great colour performance and are reliant on battery life. Where size is an issue, AMOLED will also grow to dominance thanks to its superior thinness. But for all other technologies, particularly in industrial applications, TFT-LCD offers bright, affordable display technology that is continually improving as the challenge from AMOLED rises.
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.
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.
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.
Samsung isn’t the only company that is good at marketing, there is another! Apple has coined the term “Retina” for its displays. The term was first used for its smartphones with the launch of the iPhone 4, as it offered a significantly greater pixel density (over 300 ppi) when compared to the iPhone 3GS. Later came Retina HD, which applies to iPhones with at least a 720p screen resolution.
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.
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.

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.
Over time, the purpose of using mobile phones or Smartphones has changed. Comparatively, it has now become a basic necessity of every individual. Smartphone has dramatically transformed the lives of individuals. It has now become a mini-computer that everyone carries in their pocket. Instead, you can have multiple things at your fingertips in a few seconds. While there are plenty of things to look for, AMOLED vs OLED is also a part of it.
Before purchasing any Smartphone, everyone goes through a list of specifications. This list includes display type, screen size, battery backup, supported operating system, total internal memory, and many others. Today, we have brought a comprehensive study of the significant display technologies available nowadays.
This article will introduce you to AMOLED vs OLED display technologies. Then, we will discuss the properties of both display technologies, followed by the difference between AMOLED vs OLED.
AMOLED stands for Active Matrix Organic Light Emitting Diode. This type of display is generally for large platforms. It contains TFT, which further consists of a storage capacitor. It also works on the same principle as OLED displays.
AMOLED offers no restriction on the size of the display. The power consumption of AMOLED is much less than other display technologies. The AMOLED provides incredible performance. It is thinner, lighter, and more flexible than any other display technology like LED, or LCD technology.
The AMOLED display is widely used in mobiles, laptops, and televisions as it offers excellent performance. Therefore, SAMSUNG has introduced AMOLED displays in almost every product. For example, Full HD Super AMOLED in Samsung Galaxy S4 and Samsung Galaxy Note 3, Super AMOLED in Samsung Galaxy S3, HD Super AMOLED in Samsung Galaxy Note, and HD Super AMOLED Plus in Samsung Galaxy S3. Apart from this, it is also used in AMOLED vs OLED creating the following:
So far, we have discussed OLED and AMOLED display technologies. Now, we will look at some of the differences between OLED and AMOLED display technology:
OLED comprises thin layers of the organic component, which emits light when the current passes through it. In this technology, each pixel transmits its own light. On the other side, AMOLED consists of an additional layer of thin-film transistors (TFTs). In AMOLED, the storage capacitors are used to maintain the pixel states.
While the technology is different among various manufacturers, Samsung’s edge AMOLED displays use plastic substrates with poly-Si TFT technology similar to how LG uses it in their POLED technology. This technology is what makes the possibility to build curved displays using an active-matrix OLED panel.
OLED display much deeper blacks as compared to AMOLED displays. You cannot see the screen in AMOLED display under direct sunlight. The AMOLED display quality is much better than the OLEDs as it contains an additional layer of TFTs and follows backplane technologies.
These organic compounds are present between the protective layers of glass or plastic. Comparatively, AMOLED comprises an active matrix of OLED pixels along with an additional layer of TFTs. This extra layer is responsible for controlling the current flow in each pixel.
The OLED display offers a high level of control over pixels. Hence, it can be turned off completely, resulting in an excellent contrast ratio compared to the AMOLED displays and less power consumption. On the other side, AMOLED has faster refresh rates than OLEDs. Also, they offer a tremendous artificial contrast ratio as each pixel transmits light but consumes more power than OLEDs.
OLED displays are comparatively much thinner compared to LCDs. Hence, it provides more efficient and bright presentations. In addition, OLED offers support for large display sizes compared to traditional LCDs. AMOLEDs remove the limitation of display sizes. one can fit it into any display size.
Putting all the points mentioned above in view, the key difference to understand appropriately is that POLED is an OLED display with a plastic substrate. On the other hand, AMOLED is Samsung’s word for its display technology which is mainly for marketing. Therefore, most phone manufacturers having AMOLED displays mean that they are using Samsung displays. It is as simple as that. To add to that, all the curved display technology is made possible because of the usage of the plastic substrate.
So, based on the points mentioned above, the difference between OLED and AMOLED displays, you can choose any of the two display technology at your convenience. Both are good, offer excellent performance, and are customised according to your requirements.
The AMOLED display has a higher quality than OLEDs since it has an additional layer of TTs and uses backplane technologies. When compared to OLED screens, AMOLED displays are far more flexible. As a result, they are substantially more expensive than an OLED display.
Window to the digital world, the display is one of the first seen features when selecting a smartphone, so a show must be good, and an AMOLED display offers the same. Offering a great viewing experience, here are the top 3 AMOLED screen smartphones available in the market right now:

Smartphone displays have advanced significantly in recent years, more so than most people realise in this technological age. Display screens are similar to windows in the mobile world, which has seen a tremendous transformation in innovative products in the last several years. People have gotten more selective when buying a phone in recent years, and although all of the functions are important, the display is always the most noticeable.
Major smartphone manufacturers attempt to provide their consumers with the most delicate devices possible that incorporate the most up-to-date technologies. In AMOLED vs OLED, AMOLED is a type of OLED and a more prominent example of both OLED and POLED, so there’s no debate about which is superior.
LCD is an acronym that stands for Liquid Crystal Display and it is one of the most commonly used display by OEMs on their devices. LCD displays are further categorised into two types on the basis of the technology used to make them. The two types are IPS LCD and TFT LCDs.
TFT stands Thin-film Transistor and de facto, it really isn’t a type of display. TFT is only the technology used to produce LCD display panels. TFT LCD displays use an ‘Active Matrix Technology” where the display transistor and capacitor have individual pixels attached to them. In fact, each pixel can have as many as four transistors; for switching them off and on easily. TFT displays are widely known for having high contrast ratios, resolution and image quality. They are also cheaper to produce but not as cheap as IPS LCD.
IPS stands for In-Plane Switching and it is the most popularly used type of LCD panels for a number of reasons. First, compared to TFT, the crystal/pixel orientation on IPS LCD is different. This modification allows for improved colour reproduction, better viewing angles, and reduced energy consumption. This is why IPS LCD is preferred over TFT by most gadgets manufacturers.
Generally, LCDs are known as the “backlit displays” because the pixels on the display are powered by a polarized light engineered to the screen. The light passes through the (horizontal and vertical) filters which help determine the pixel’s brightness. Although the inclusion of a backlight makes LCD displays (and phones) thicker, pixels are generally more closely packed, colours are more natural, and images — sharper.
OLED stands for “Organic light-emitting diode”. OLED is one of the latest display innovation used in many gadgets and electronics like smartphones and TVs. Unlike LCD displays, OLED panels produce their own light and do not rely on a backlight. This self-emission is achieved when an electrical current passes through two conductors with an organic carbon-based film between them.
Regarding quality, OLED are generally better at displaying blacks. They are also slimmer, dissipate less heat, and possess better contrast ratio when compared to LCDs. However, they are more expensive to produce and in turn lead to an increase in the price of smartphones they are used on. Shorter lifespan is also a downside to OLED displays.
AMOLED is an advanced type of OLED display that uses an “Active Matrix” technology. AMOLED is the acronym for Active Matrix Organic Light Emitting Diode (AMOLED). Like OLED, AMOLED pixels also emit their own light and further uses an active matrix system attached to a thin-film transistor (TFT) to exert more control over each pixels. This results to better visual experience; darker blacks, deeper brights, and higher refresh rates.
AMOLED panels are mostly used in big-sized smartphones as it supports almost any display size. One downside to AMOLED panels, though, is poor usability under sunlight.
Also called S-AMOLED, Super AMOLED is an upgrade of AMOLED panels. Unlike regular AMOLED, this upgrade uses almost the same technology but with architectural modifications that makes it better. In S-AMOLED, the touch sensor component have been integrated with the screen; both are separated in regular AMOLED.
This difference results in brighter display, reduced power consumption, reduced sunlight reflection, enhanced outdoor readability, and wider viewing angles. Super AMOLED is one the best displays out there and can be found on many flagship devices like the Samsung Galaxy A7 (2018) with three rear cameras, Samsung Galaxy Note9.
You can easily identify your smartphone’s screen type through a simple Google search of your phone specifications. You should see your device’s screen type under the display department. The image below shows the screen type (IPS LCD) of the Coolpad Note 5.
OLED displays are commonplace on all high-end phones, tablets, smartwatches, televisions, and even many of the many budget phones. However, there isn"t one type of OLED technology. Depending on your device, you may have an OLED, AMOLED, or POLED display.
OLED promises inky blacks, high contrast, low response times, and incredible brightness. There are a few downsides (primarily the burn-in phenomenon), but overall it"s the best screen technology you"ll find. We explain the background behind the acronyms, the difference between POLED and AMOLED, and which is better, helping you choose the right phone.
Before we get into the differences between the types of OLED screens, let"s look at the similarities. Regardless of your OLED device, whether a laptop or a smartphone, there are some standard fundamentals.
Every OLED screen comprises millions of diodes, hence the name organic light-emitting diode. Viewed under a microscope, each screen consists of a series of red, green, and blue diodes that can be individually turned on and off. Behind this, the light-emitting pixels of an OLED display emit blue and yellow light. The yellow and blue light combine to form white light, passing through the red, green, and blue subpixels to produce a single pixel. Because each pixel handles its light and color, OLED displays do not need a separate backlight.
As an OLED screen doesn"t need a backlight, black is produced by turning off the pixels, resulting in deep, consistent blacks. This allows manufacturers to implement things like an always-on display without quickly burning through battery life.
Another critical advantage of OLED tech is high contrast ratios. Technically, OLED displays offer "infinite contrast," or 1,000,000:1 contrast ratios. This is because OLED displays reproduce black by turning off pixels entirely, and contrast is measured by comparing the brightest part of the screen to the darkest part. Improved contrast makes on-screen content more vivid and makes bright highlights look more impressive. This also means that OLED screens can reach higher brightness than the best IPS LCD screens.
OLED displays can display more colors with greater color accuracy than their LCD peers. This is great for photographers and videographers using their phones to preview, edit, and create content.
OLED displays have near-instantaneous pixel response times. Older LCD screens often have lower response times because to change from one color to another, they must physically change the orientation of a liquid crystal, which takes time. An OLED display turns a subpixel on or off with an electrical charge, giving them a faster pixel response time.
The omission of a separate backlight and the use of fewer components means OLED displays can be thinner than LCDs, making them more versatile in their applications. This means they are more fragile and prone to damage in high-impact or high-stress situations. Engineers combat this by using technologies like Gorilla Glass and robust metal frames. Mitigation strategies like these raise the cost of OLED screens.
OLED displays can also be transparent, depending on the materials used. Transparent displays are helpful for in-display fingerprint readers and under-display cameras, which allow manufacturers to design smartphones with fewer and smaller bezels, notches, and display cutouts. When notches and cutouts are necessary, OLED displays have more even brightness around those cutouts and notches compared with LCDs, where the backlight has to make it around the cutout, and things get a little messy.
Of particular import to smartphones, OLED displays often consume less power, especially when displaying dark images or UI elements, thanks to the pixel-level regulation of brightness. However, at max brightness, an OLED screen usually uses more power than an equivalent LCD.
As with any new technology, OLED tech is not without its flaws.OLED displays are prone to degradation from age and UV exposure, resulting from the organic nature of the molecules that make up the diodes. The organic nature of OLED displays also leads to a phenomenon called screen burn-in, where static UI elements like menus, navigation bars, and status bars (elements that are on-screen for long periods) leave a permanent ghost image, even when they are not displayed. However, burn-in has been somewhat mitigated by pixel shifting and technological advancements in recent years.
Early OLED screens placed all the organic materials on a glass substrate. However, glass is rigid, so a flexible plastic substrate is needed to create foldable display screens, leading to the creation of POLED screens.
To get to the resolution and size of a phone, an AMOLED screen (active matrix organic light emitting diode) is needed. Older, passive matrix OLED displays (PMOLED) require higher voltages for higher pixels/resolutions. The higher the voltage, the lower the screen"s lifetime.
Thin-film transistor (TFT) arrays used in modern active-matrix OLED displays control the charging of the display"s storage capacitors. These TFTs control current flow, resulting in more energy-efficient OLED panels than PMOLED displays. This allows a larger display size without compromising resolution, lifetime, or power consumption.
QLED is found in TVs and large computer monitors because that"s where it sees the most benefit. OLED displays in phones are small enough, bright enough, and cheap enough that QLED wouldn"t be able to compete or offer any practical benefit to the end user.
Resolution is the number of pixels a screen has. It is usually written as a ratio: pixels on the long side by pixels on the short side, for example, 1920 x 1080. Most smartphone displays have a resolution between 720p (1280 x 720) on the low-end and 4k (3480 x 2160) on some Sony models. While 4k is excessive and rare for anything under 15 inches, 720p, 1080p, and 1440p are all common smartphone resolutions.
The ideal smartphone screen resolution depends on the screen size. A metric called pixels per inch (PPI) describes the display"s number of pixels in a vertical or horizontal inch. For a 6-inch display, you should aim for at least 1080p or above 350 PPI. This will ensure that the text is crisp.
So why do manufacturers use odd-pixel layouts? It depends on the manufacturer and its goals. Samsung uses PenTile displays, which use RGBG instead of RGB subpixels, to combat image retention on its AMOLED displays. WRGB displays add a separate white subpixel to boost brightness on OLED displays—a technology that is otherwise notoriously dim.
There are reasons for these odd layouts. PenTile, for example, increases the number of green subpixels to reduce the effect of burn-in and increase panel lifespan. Still, many people are sensitive to the decreased resolution and clarity that often results from unorthodox subpixel layouts. Part of these resolution problems lies in subpixel antialiasing, which works on a subpixel basis to smooth out text and on-screen elements. Some do this better than others, which is why an iPhone 13"s screen seems sharper than the competition. However, even Samsung acknowledges that PenTile layouts suffer in terms of resolution and clarity.
Smartphones are often used outside in bright sunlight, so display brightness is a huge factor. Display brightness is measured in nits or cd/m². Peak brightness is the momentary maximum brightness of a small portion of a screen, while sustained brightness is a more realistic representation of the brightness of the whole display. Aim for above 600 nits of sustained brightness since anything below may cause legibility issues in bright conditions. On the other hand, brightness is measured logarithmically, not linearly, meaning 1,200 nits is only twice as bright as 300 nits. This is important since many manufacturers lean heavily on high brightness metrics as a marketing point.
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.
However, for even greater contrast control, done individually at each point on the screen, it is necessary to go to panels equipped with microLED technologies – still cost-prohibitive in 2021 – or OLED, which until recently were manufactured on a large scale only in sizes for smartphones or televisions.Affiliate offer
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.
To make it easier to compare different models, brands usually adopt the same naming scheme made popular by the TV market with terms like HD, FullHD and UltraHD. But with phones adopting a wide range of different screen proportions, just knowing that is not enough to know the total pixels displayed on the screen.Common phone resolutions
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.
The name coined by Apple"s marketing department is applied to screens which, according to the company, the human eye is unable to discern the individual pixels from a normal viewing distance. In the case of iPhones, the term was applied to displays with a pixel density that is greater than 300 ppi (dots per inch).
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.
Nit, or candela per square meter in the international system (cd/m²), is a unit of measurement of luminance, i.e. the intensity of light emitted. In the case of smartphone screens and monitors in general, such a value defines just how bright the display is - the higher the value, the more intense the light emitted by the screen.
The result is smoother animations on the phone, both during regular use and in games, compared to screens that have a 60 Hz refresh rate which remains the standard rate in the market when it comes to displays.
Originally touted to be a "gimmick" in 2017, with the launch of the Razer Phone, the feature gained more and more momentum in due time, even with a corresponding decrease in battery life. In order to make the most of this feature, manufacturers began to adopt screens with variable refresh rates, which can be adjusted according to the content displayed - which is 24 fps in most movies, 30 or 60 fps in home video recordings, and so forth.
The same unit of measurement is used for the sampling rate. Although similar, the value here represents the number of times per second the screen is able to register touches. The higher the sample rate, the faster the smartphone registers such touches, which results in a faster response time.
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.
A microLED display has one light-emitting diode for each subpixel of the screen - usually a set of red, green, and blue diodes for each dot. Chances are it will use a kind of inorganic material such as gallium nitride (GaN).
This is one of the reasons that explain the adoption of such technology to date remains rather limited in scope. You will see them mainly in large screens of 75 to 150 inches only, which enable 4K resolution (3,840 x 2,160 resolution, which is close to 8.3 million pixels or 24.8 million RGB subpixels). This is a huge number of pixels to look at!
Each technology has its own advantages and disadvantages but in recent years, OLED screens have gained prominence, especially with the adoption of the component in high-end flagship smartphones. It gained an even greater degree of popularity after the launch of the iPhone X, which cemented the position of OLED panels in the premium segment.
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 addition, the organic diodes that give OLED screens their name can lose their ability to change their properties over time, and this happens when the same image is displayed for a long period of time. This problem is known as "burn-in", tends to manifest itself when higher brightness settings are applied for long periods of time.
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.
Now let’s backtrack and define what an AMOLED display is, exactly. The best way to do this is to divide the acronym itself into two different parts, active-matrix and organic light-emitting diode.
The diode part of that acronym is the base technology for the display, and it’s based using a specialized thin-film type of display. The display is basically divided into four layers-the substrate, the thin-film transistor (TFT) array, the organic active layers and finally, the cathode layers, which is the upper layer in this arrangement.
The organic aspect of this arrangement is the key to the technology. The way it works is that the organic active layer consists of pixels that produce light once energy is transferred to the TFT layer or integrated into it.
AMOLED displays aren’t just common in phones, either. You can find them in high-end televisions, devices that have an Android smartphone screen, and other hand-held devices, so they’re basically pervasive throughout modern society.
This activates a set of switches to control the pixel flow, and this whole setup is what allows AMOLED displays to provide such vivid graphics while consuming a relatively small array of power, i.e.., the power consumption depends the brightness and color settings for the display, which are regulated by the switching arrangement.
In addition, AMOLED displays also usually have a faster display time, and the technology allows designers more flexibility when it comes to the size of the display. For users, the advantages include sharper graphics, better photos and more readable displays, even in bright sunlight.
There are some disadvantages when it comes
