What is the name of the smartphone screen? Smartphone Screen Types: Which is Best for the Eyes? Who manufactures matrices

LCD, TFT, IPS, AMOLED, P-OLED, QLED - the list of technologies used to manufacture smartphone matrices is constantly growing. And getting lost in these wilds is easy even for a geek, not to mention a simple user. Today we in plain language Let's explain what is the difference between them, as well as what advantages and disadvantages each of them has.

There are two basic technologies on the basis of which most displays of modern smartphones are created. These are LCD and OLED. All other types and names are just their derivatives. It remains for us to figure out which ones belong to the first type, and which ones to the second.

LCD

LCD (Liquid Crystal Display) - liquid crystal screens that have become ubiquitous: they are used in TVs, monitors, smartphones, etc. Liquid crystals, which underlie the technology, have two important properties: fluidity and anisotropy.

Anisotropy is the ability of a crystal to change its properties depending on its location in space.

In screens, this feature is used to control light transmission. With the help of transistors, a current is supplied to the LCD matrix, which changes the orientation of the crystals. Then light falls on them, passing through several filters, and as a result, a pixel appears on the screen. desired color. Note that all LCD screens require a backlight source: external (for example, Sun rays) or built-in (e.g. LEDs).

LCD-matrices of smartphones include: TN, IPS, PLS, as well as their numerous modifications. This also includes VA/MVA/PVA technology, which is not widely used. However, before we move on to the types of matrices, it is necessary to understand the abbreviation TFT, which occurs both separately and in various combinations, for example, TFT LCD or TFT IPS.

TFT(thin-film transistor) is a type of LCD display that uses an active matrix to control liquid crystals: its design includes thin-film transistors. It should be said right away that absolutely all modern gadgets with LCD, as well as AMOLED displays, have an active matrix: the passive one is practically not used.

That is, if we are talking about IPS, TN or VA / MVA / PVA, then we mean that they all refer to TFT LCD displays.

TN+film

TN + film (Twisted Nematic + film) is one of the very first matrix manufacturing technologies. It got its name for the characteristic arrangement of crystals that twist into a spiral. Most often, such matrices are simply called TN.

Advantages:

• short response time - 16 ms (at the dawn of technology, this was a record figure among all types of matrices);
• low production cost.

Flaws:

• small viewing angles;
• low level of contrast;
• low color rendering.

IPS

IPS (in-plane switching)- in such screens, when receiving an electrical impulse, the crystals do not twist into a spiral, but rotate perpendicular to their initial position. This feature allowed to increase the viewing angle almost to the maximum - 178 degrees. Thus, IPS displays have replaced TN, but they also have their drawbacks.

Advantages:

• maximum viewing angles - up to 178 degrees;
• natural color reproduction, including near-perfect black;
• high level of contrast.

Flaws:

• high cost compared to TN;
• response time (in early IPS displays) was faster than TN.

Samsung's proprietary development, which is an improved version of IPS designed for the mass market, but for a number of reasons unsuitable for professional devices.

Advantages:

• high pixel density;
• wide viewing angle up to 178 degrees;
• low response time;
• low power consumption;
• high contrast;
• lower production cost (15% lower compared to IPS matrices).

Most of the shortcomings of IPS technology have now been eliminated. In the screenshots below, you can see the evolutionary path that she managed to go through.

OLED

In OLED matrices (Organic light-emitting diode), instead of liquid crystals, organic light-emitting diodes are used, which do not require backlighting. When applying for them electrical impulses they start to glow.

In turn, OLED, according to the method of controlling diodes, is divided into PMOLED (Passive Matrix) and AMOLED (Active Matrix), and the former is practically not used in new smartphones.

AMOLED uses the aforementioned thin film resistors (TFT technology) to drive the diodes.

A variety of AMOLED matrices are SUPER AMOLED (Samsung's marketing "chip") - in such screens there is no air gap between the touch screen layer and the matrix. In the case of IPS matrices, this “airless” technology is called OGS (One Glass Solution). Although it is rather design feature and it is impossible to single out SUPER AMOLED matrices as a separate type.

Another subspecies of AMOLED is P-OLED matrices. They are distinguished by the presence of a plastic screen substrate (glass is used in AMOLED). Thanks to this, manufacturers have the opportunity to create curved screens.

Advantages:

• smaller dimensions and weight compared to LCD displays;
• low power consumption;
• do not require backlighting;
• high contrast;
• instant response;
• the ability to change the form factor of screens (flexible displays);
• large viewing angles close to the maximum (180 degrees);
• a wide range of operating temperatures (from -40 degrees to +70).

Flaws:

• short service life compared to LCD displays;
• high price;
• sensitivity to moisture.

However, as technology advances, the cons of OLED displays are gradually disappearing.

The "unique" Retina and Super Retina displays that the iPhone is equipped with have nothing to do with the matrix production technology. This is just a marketing ploy of the company. In fact, Apple smartphones use the same IPS and OLED matrices.

Conclusion

At the moment, the difference (color reproduction, contrast, viewing angles, energy efficiency, etc.) between LCD and OLED screens is rapidly decreasing. However, the following trend is emerging: LCD screens are gradually becoming obsolete and inferior to OLED displays. And those, in turn, evolve into QLED displays. So far, these technologies are expensive to manufacture and are in their infancy, but it is possible that in the near future all electronics will be equipped with just such screens.

By 2018, the rivalry between screen technologies was reduced to the fact that there were only two worthy options left on the market. TN matrices were pushed out, VA was not used in mobile devices, and something new has not yet been invented. Therefore, competition has unfolded between IPS and AMOLED. Here it is worth recalling that IPS, LCD LTPS, PLS, SFT are the same as OLED, Super AMOLED, P-OLED, etc. are just varieties of LED technology.

A lot has already been said on the topic of which is better, IPS or AMOLED. But technology does not stand still, so in 2018 it will not be superfluous to make adjustments and analyze it taking into account today's realities. After all, both types of matrices are constantly being improved, some shortcomings are being eliminated, or these disadvantages are becoming less significant.

What is better for a smartphone, IPS or AMOLED, now let's try to find out. To do this, we will weigh all the pros and cons of each of the technologies in order to identify the absolute leader by the preponderance of strengths or, taking into account the specifics, decide what is best in specific conditions.

Pros and cons of IPS displays

The development and improvement of IPS displays has been going on for two decades, and during this time the technology has managed to acquire a number of advantages.

IPS matrix layers

Benefits of IPS panels

IPS matrices are the best among all types of LCD panels due to a number of advantages:

• Availability. Over the years of development, many companies have massively mastered the technology, making the mass production of IPS screens inexpensive. The cost of a screen for a smartphone with FullHD resolution now starts at around $10. Due to the low price, such screens make smartphones more affordable.
• Color rendition. A well-calibrated IPS screen renders colors with maximum fidelity. That is why professional monitors for designers, graphic artists, photographers, etc. are produced on IPS matrices. They have the largest coverage of shades, which allows you to get realistic colors of objects on the screen.
• Fixed power consumption. Liquid crystals that form an image on an IPS screen consume almost no current, the backlight diodes are the main consumer. Therefore, the power consumption does not depend on the image on the display and is determined by the backlight level. Thanks to a fixed power consumption, IPS screens provide approximately the same autonomy when watching movies, surfing the web, writing, etc.
• Durability. Liquid crystals are almost not subject to the process of aging and wear, therefore, in terms of reliability, IPS is better than AMOLED. Backlight LEDs can degrade, but the service life of such LEDs is very long (tens of thousands of hours), so even in 5 years the screen almost does not lose brightness.

Disadvantages of IPS matrices

Despite significant advantages, IPS also has disadvantages. These shortcomings are fundamental, therefore, by improving the technology, they are not eliminated.

• Black purity problem. Liquid crystals that display black do not block light from the backlight 100%. But since the backlight of the IPS screen is common to the entire matrix, its brightness does not decrease, the panel remains illuminated, as a result, the black color is not very deep.

In the dark, you can see that black reflects gray.

• Low contrast. The contrast level of LCD matrices (about 1:1000) is acceptable for comfortable image perception, but AMOLED is better than IPS in this indicator. Due to the fact that blacks are not very deep, the difference between the brightest and darkest pixel in such screens is noticeably smaller than in LED matrices.
• Great response time. The pixel response speed of IPS panels is low, on the order of ten milliseconds. This is enough for normal image perception when reading or watching a video, but not enough for VR content and other demanding tasks.

Pros and cons of AMOLED displays

OLED technology is based on the use of an array of miniature LEDs located on a matrix. They are independent, so they offer a number of advantages over IPS, but are not without disadvantages.

AMOLED matrix layers

Advantages of AMOLED matrices

AMOLED technology is newer than IPS, and its creators have taken care to eliminate the disadvantages that are characteristic of LCD displays.

• Separate glow of pixels. In AMOLED screens, each pixel itself is a light source and is controlled by the system independently of the others. When displaying black, it does not glow, and when showing mixed shades, it can produce increased brightness. Due to this, AMOLED screens show better contrast and black depth.

Black pixels do not glow at all

• Almost instant reaction. The pixel response speed on the LED matrix is ​​orders of magnitude higher than that of IPS. Such panels are able to display a dynamic picture with a high frame rate, making it smoother. This feature is a plus in games and when interacting with VR.
• Reduced power consumption when displaying dark tones. Each pixel of the AMOLED matrix glows independently. The lighter its color, the brighter the pixel, so when displaying dark tones, such screens consume less energy than IPS. But in the process of displaying white AMOLED panels show a similar, or even greater than that of IPS, battery consumption.
• Small thickness. Since AMOLED matrices do not have a layer that scatters light from the backlight onto liquid crystals, such displays have a smaller thickness. This allows you to reduce the size of the smartphone, while maintaining its reliability and without sacrificing battery capacity. In addition, in the future, it is possible to create flexible (and not just curved) AMOLED matrices. For IPS, this is not possible.

Disadvantages of AMOLED matrices

AMOLED matrices also have disadvantages, and the culprit of most troubles is one. These are blue LEDs. Mastering their production is more difficult, and they are inferior in quality to green and red ones.

• Blue or PWM. Choosing a smartphone with an AMOLED screen, you have to choose between pulse-width brightness control and blue light tones. All due to the fact that with a continuous glow, blue subpixels are perceived more strongly than red and green ones. You can fix this by using PWM dimming, but then another drawback pops up. At maximum screen brightness, there is no PWM or the adjustment frequency reaches about 250 Hz. This indicator is on the border of perception and almost does not affect the eyes. But with a decrease in the backlight level, the PWM frequency also decreases, as a result, at low flicker levels with a frequency of about 60 Hz, it can lead to eye fatigue.

• Blue burnout. There is also a problem in the blue diodes. Their service life is shorter than green and red ones, so color distortion is possible over time. The screen goes yellow, the white balance shifts towards warm tones, and the overall color reproduction deteriorates.

Ophthalmologists do not get tired of repeating that visual contact with the screen of the gadget is not the best pastime for our eyes. What characteristics of the smartphone screen affect vision and what needs to be considered when choosing a display, we will tell in this material.

Medical "educational program" from CHIP

A person who spends a lot of time in the company of a smartphone or any other device with a display should be wary of two things. The first of them is the dryness of the eyeball, the second is the risk of developing myopia.

Normally, we blink about eighteen times a minute. With this frequency of eyelid movement, the cornea of ​​​​the eye is constantly moistened with tear fluid. Looking at the screen, whether it's a monitor, a TV screen or a smartphone display, we simply forget to blink, which causes a feeling of dry and tired eyes. Scientists have calculated that upon contact with the screen, the frequency of lowering the eyelids decreases to 2-3 times per minute - almost 9 times!

Protective glasses without diopters will be useful not only for hipsters, but also for gadgetophiles

Myopia, or myopia, caused by contact with the screen, is true and false. First, there are spasms of the eye muscles, due to which, with a sharp separation from the screen, the surrounding reality begins to “blur”. This is the so-called false myopia. If the eye muscles are constantly under tension, it gradually increases, turning into true myopia, in which the eyeball is slightly extended. There's nothing you can do about it - you have to wear glasses.

How does the display of a digital device affect our eyes so badly? There are several important characteristics of a smartphone screen that determine how harmful contact with it is to human vision.

PPI: number of dots per inch

The first characteristic of a smartphone display that is important from an ophthalmological point of view is the ratio between its size and resolution, that is, the number of dots per inch (pixels-per-inch or PPI).

In terms of harm to vision, this ratio should be considered as follows. A small, high resolution screen is much safer on the eyes than a large, low one. On a small screen with a high resolution, the PPI will be higher because the pixels will be closer together and the picture will be clearer.

And vice versa: the larger the screen and the lower the resolution, the lower the PPI, and the more blurry the image becomes. Because of this, our eyes will be forced to strain, independently adjusting the sharpness. This leads to the aforementioned overexertion and muscle spasm, which can subsequently lead to myopia.

If you do not take care of yourself, then glasses will soon become a sad necessity.

If you want to choose a smartphone that will be safer on the eyes, pay attention to the screen size (in inches) and resolution (width in pixels and height in pixels) when buying. The ratio between them will be the PPI value.

For example, let's take two screens with the same resolution of 720x1280 (HD). The first one has a diagonal of 4.3″ and its PPI will be 342. The second one has a diagonal of 4.7″ and its PPI is 312. Despite the fact that both displays are HD screens, the first one is still safer for the eyes.

You can calculate the PPI of your dream smartphone using special online calculators - for example, this one. And if you are curious about how bad for the eyes your current smartphone is, you can visit the DPI love site, which will automatically determine the actual diagonal and screen resolution and calculate your PPI.

Brightness and backlight technology

The human eye is not designed to look at bright light for a long time. How long can you last staring at a light bulb? Smartphones and other digital gadgets place us in an artificial environment in which we are forced to distinguish between text and images for a long time against bright lighting.

This is the reason for the unnatural reaction of the body: we stop blinking. The eyeball is not wetted with a sufficient amount of tear fluid, and dryness, tension, and a feeling of "sand" appear in the eyes. All together is called special medical term- "dry eye syndrome".

The following rule applies here: the brighter and sharper the light, the more harmful it is to the eyes. The first parameter depends on how brightly the screen shines in relation to the environment (reading from the screen at night in the dark is definitely harmful), but this can be adjusted in the smartphone settings. The second is more dependent on the type of display and the backlight technology used in it.

We protect ourselves from the sun with dark glasses, but for some reason, nothing from backlighting.

Older LCD family displays use continuous backlight technology. Liquid crystals, which form the basis of such displays, are illuminated from the inside, due to which the image is formed. Depending on the display subtype, the backlight may be brighter or more muted. For example, cheaper LCD-TFT displays are dimmer than more advanced LCD-IPS, which use enhanced backlighting. However, the effect here is the same: the eyes are constantly exposed to bright light.

More modern OLED displays are less harmful in this regard, since their backlighting is selective. In fact, the OLED display is "always off" and the LEDs that form the basis of the screen light up depending on where and what needs to be displayed. Accordingly, the light exposure of these screens is much lower than that of their predecessors, and the light is much softer and harmless to the eyes.

In general, we can say that it will not work to clearly rank smartphones in terms of harmlessness to the eyes. It is impossible to say with certainty that a smartphone does not damage eyesight just because it has Ultra HD resolution or uses Super AMOLED technology. To assess how the screen is suitable for your eyes, you need to proceed from a set of factors, and first of all - for reasons of your own comfort.

A smartphone can have powerful hardware and take excellent pictures, but the user will still not be completely satisfied with it if the screen quality leaves much to be desired. Unfortunately, in terms of display performance, many buyers are complete laymen. Therefore, it is so important to consider what types of smartphone displays are found and what parameters you need to pay attention to when choosing a gadget.

Previously, all touchscreen phone displays were classified into:

1. capacitive. The principle of operation is as follows: the user's finger transfers the charge, and the device software calculates in which area of ​​the screen the change occurred.
2. Resistive. Behind the screen are two metal plates. When the first is pressed against the second, the smartphone reacts. Smartphones with resistive screens were often attached.

The use of resistive displays was inconvenient, since you had to apply force when pressing. Resistive displays finally disappeared from shop windows in 2011, and the last “swallow” was the model Samsung S5230 star , once very popular among the fair sex.

Common Display Technologies

There are such types of displays:

TFT

Screens made using this technology are mounted in budget gadgets. Image quality can be very decent, but some imperfections will still be noticeable (such as minimal viewing angles). The peculiarity of TFT displays is that they are not capable of producing perfect black - only dark gray.

IPS

Advanced TFT technology that guarantees high contrast, saturated colors(in particular, black and white), large viewing angles. Recently, phones are becoming more common - even Chinese sellers are abandoning TFT technology.

AMOLED

Matrix consisting of organic light-emitting diodes. This technology not only provides brighter colors than IPS, but also allows the smartphone to work longer offline, because the black color is formed by turning off some of the LEDs. you can usually find it on Samsungs, which is not surprising, because it was the Korean company that developed them.

SuperAMOLED

Later, she improved the design of AMOLED displays by removing the air gap between the screen and the touch layer. Due to this, image detail, color saturation have increased, and the display itself has become thinner. Curiously, Super AMOLED screens have been nicknamed "acid" by the people because of their excessive brightness.

SuperLCD

Such screens are rare on smartphones - One X was one of the gadgets with a similar display. SLCD technology provides warm and rich colors, but puts the smartphone down faster than AMOLED and IPS.

What gives screen resolution?

Any screen consists of a huge number of "squares" - pixels that fit snugly together. Each of the pixels in turn consists of 3 subpixels (subpixels): red (R), green (G), blue (B). As nutrition is received, they mix in different proportions and give some color. You can calculate the number of pixels on a device screen by multiplying two display resolution parameters: height and width. For example, an HD display ( 1280 * 720 ) comprises 921600 pixels. That is, the higher the resolution, the clearer the picture will be. On gadgets with a minimum resolution, the “squares” will be visible to the naked eye.

There is another indicator - DPI, which reflects the density of dots per inch of the screen. When choosing a gadget, the DPI indicator should be given even more attention than the resolution, because the screen sizes of smartphones are different. Note that a person with excellent and under ideal conditions is able to discern density up to a maximum of 350 DPI. In real conditions, 250 DPI is enough. This means that for a smartphone with a diagonal of 4.5-5 inches, an HD display abounds. Buying a gadget with more "cool" display characteristics will only lead to negative consequences: firstly, the buyer will overpay, and secondly, the smartphone will run out faster.

What are the best screen sizes?

Apple visionary Steve Jobs determined that the most appropriate screen size for a smartphone is 3.5 inches; this is exactly what the popular models 4 and 4S had. With a diagonal of 3.5 inches, the average user can reach the thumb of the hand (which holds the gadget) even to the farthest point of the display.

However, you can now find a smartphone with such a diagonal only in a showcase with budget models. The trend of increasing display sizes continues to gain momentum - large companies are already releasing smartphone-class devices with screens as large as 6 inches! For comfortable work, 4.7-5 inches is enough - such a gadget can still be controlled with one hand. Smartphone bigger size will cause inconvenience both during use and when stored in a pocket.

Conclusion

When choosing a smartphone, you need to remember that chasing outstanding display characteristics is pointless - the owner of a device with a 4K screen resolution will not receive any visible advantages. On the contrary, the user will be doomed to the constant wearing of the memory, since the duration battery life smartphone directly depends on the display settings.

Smartphone display technologies do not stand still, they are constantly being improved. Today there are 3 main types of matrices: TN, IPS, AMOLED. Often there are disputes about the advantages and disadvantages of IPS and AMOLED matrices, their comparison. But TN-screens have long been out of fashion. This is an old development, which is now practically not used in new phones. Well, and if it is used, then only in very cheap state employees.

Comparison of TN matrix and IPS

TN matrices were the first to appear in smartphones, so they are the most primitive. The main advantage of this technology is its low cost. The cost of a TN display is 50% lower than that of other technologies. Such matrices have a number of disadvantages: small viewing angles (no more than 60 degrees. If more, the picture begins to distort), poor color reproduction, low contrast. The logic of manufacturers to abandon this technology is clear - there are a lot of shortcomings, and all of them are serious. However, there is one advantage: the response time. In TN matrices, the response time is only 1 ms, although in IPS screens, the response time is usually 5-8 ms. But this is just one plus that cannot be put in opposition to all the minuses. After all, even 5-8 ms is enough to display dynamic scenes and in 95% of cases the user will not notice the difference between the response time of 1 and 5 ms. The photo below clearly shows the difference. Note the color distortion at an angle on the TN matrix.

Unlike TN, IPS matrices show high contrast and have huge viewing angles (sometimes even maximum ones). It is this type that is the most common, and they are sometimes referred to as SFT matrices. There are many modifications of these matrices, so when listing the pros and cons, you need to keep in mind any particular type. Therefore, below, to list the advantages, we will mean the most modern and expensive IPS-matrix, and to list the minuses, the cheapest.

Pros:

1. Maximum viewing angles.
2. High energy efficiency (low energy consumption).
3. Accurate color reproduction and high brightness.
4. The ability to use high resolution, which will give a high density of pixels per inch (dpi).
5. Good behavior in the sun.

Minuses:

1. Higher price compared to TN.
2. Distortion of colors with a large tilt of the display (however, viewing angles are not always maximum on some types).
3. Color oversaturation and under saturation.

Today, most phones have IPS-matrices. Gadgets with TN displays are used only in the corporate sector. If a company wants to save money, then it can order monitors or, for example, phones for its employees at a lower price. They may have TN matrices, but no one buys such devices for themselves.

Amoled and SuperAmoled screens

Most often, Samsung smartphones use SuperAMOLED matrices. This company owns this technology, and many other developers are trying to buy or borrow it.

The main feature of AMOLED matrices is the depth of black. If you put an AMOLED display and IPS side by side, then the black color on the IPS will appear light compared to AMOLED. The very first such matrices had incredible color reproduction and could not boast of color depth. Often there was a so-called acidity or excessive brightness on the screen.

But the developers at Samsung have corrected these shortcomings in SuperAMOLED screens. These have specific advantages:

1. Small power consumption;
2. The best picture compared to the same IPS matrices.

Flaws:

1. higher cost;
2. The need to calibrate (adjust) the display;
3. Rarely can be different term diode work.

AMOLED and SuperAMOLED matrices are installed on the most TOP flagships due to the best picture quality. The second place is occupied by IPS screens, although it is often impossible to distinguish AMOLED and IPS matrix in terms of picture quality. But in this case, it is important to compare subtypes, not technologies in general. Therefore, you need to be on the alert when choosing a phone: advertising posters often indicate technology, and not a specific matrix subtype, and technology does not play a key role in the final picture quality on the display. BUT! If TN + film technology is indicated, then in this case it is worth saying “no” to such a phone.

Innovation

Removal of the OGS air gap

Engineers introduce image enhancement technologies every year. Some of them are forgotten and not applied, and some make a splash. OGS technology is just that.

Standardly, the phone screen consists of a protective glass, the matrix itself and an air gap between them. OGS allows you to get rid of the extra layer - air gap- and make the matrix part of the protective glass. As a result, the image seems to be on the surface of the glass, and not hidden under it. The effect of improving the display quality is evident. Over the past couple of years, OGS technology has been unofficially considered the standard for any more or less normal phones. Not only expensive flagships are equipped with OGS screens, but also state employees and even some very cheap models.

Screen glass bend

The next interesting experiment, which later became an innovation, is 2.5D glass (that is, almost 3D). Due to the bends of the screen at the edges, the picture becomes more voluminous. If you remember, the first smartphone samsung galaxy Edge made a splash - it was the first (or not?) to get a 2.5D glass display, and it looked amazing. On the side, there was even an additional touch panel for quick access to some programs.

HTC had an attempt to do something unusual. The company has created a smartphone Sensation with a concave display. Thus it was protected from scratches, although to achieve more good failed. Now such screens cannot be found due to the already durable and scratch-resistant protective glass Gorilla Glass.

HTC didn't stop there. The LG G Flex smartphone was created, which not only had a curved screen, but also the body itself. This was the "chip" of the device, which also did not gain popularity.

Stretchable or flexible screen from Samsung

As of mid-2017, this technology is not yet used in any phone available on the market. However, Samsung, in videos and in its presentations, shows AMOLED screens that can stretch and then return to their original position.

Photo of flexible display fromSamsung:

The company also presented a demo video clip, where the screen is clearly visible, arching by 12 mm (as the company itself claims).

It is quite possible that soon Samsung will make a very unusual revolutionary screen that will amaze the whole world. This will be a revolution in terms of display development. It is difficult to even imagine how far the company will go ahead with such technology. However, it is possible that other manufacturers (Apple, for example) are also developing flexible displays, but so far there have been no such demonstrations from them.

The best smartphones with AMOLED matrices

Given that SuperAMOLED technology was developed by Samsung, it is mainly used in the models of this manufacturer. In general, Samsung leads the way in developing screens for mobile phones and TVs. We have already understood this.

To date, the best display of all existing smartphones is the SuperAMOLED screen in the Samsung S8. This is even confirmed in a DisplayMate report. For those who don't know, Display Mate is a popular resource that analyzes screens from start to finish. Many experts use their test results in their work.

To define the screen in S8, I even had to introduce a new term - Infinity Display. It got its name due to its unusual elongated shape. Unlike its previous screens, Infinity Display has been seriously improved.

Here is a short list of benefits:

1. Brightness up to 1000 nits. Even in bright sunlight, the content will be well readable.
2. A separate chip for the implementation of Always On Display technology. The already economical battery now consumes even less battery power.
3. Image enhancement feature. In Infinity Display, content without an HDR component acquires it.
4. Brightness and color settings are automatically adjusted based on user preferences.
5. Now there is not one, but two light sensors, which more precisely allows you to automatically adjust the brightness.

Even compared to the Galaxy S7 Edge, which had a "reference" screen, the S8's display looks better (on it, whites are really white, but on the S7 Edge, they fade into warm tones).

But besides the Galaxy S8, there are other smartphones with screens based on SuperAMOLED technology. Basically, these are, of course, models of the Korean company Samsung. But there are others too:

1. Meizu Pro6;
2. One Plus 3T;
3. ASUS ZenFone 3 Zoom ZE553KL - 3rd place in the TOP of Asusu phones (located).
4. Alcatel IDOL 4S 6070K;
5. Motorola Moto Z Play and more

But it is worth noting that although the hardware (that is, the display itself) plays a key role, software is also important, as well as secondary software technologies that improve picture quality. SuperAMOLED displays are famous primarily for the ability to widely adjust the temperature and color settings, and if there are no such settings, then the point of using these matrices is slightly lost.
