Which is better super lcd or amoled. Super Amoled Matrix

By 2018, the rivalry between screen technologies boiled down to only two decent options left on the market. TN matrices have been replaced, VA in mobile devices have not been used, and something new has not yet been invented. Therefore, the competition has developed between IPS and AMOLED. It is worth recalling here that IPS, LCD LTPS, PLS, SFT are the same as OLED, Super AMOLED, P-OLED, etc. are just varieties of LED technology.

On the topic of which is better, IPS or AMOLED,. But technologies do not stand still, so in 2018 it will not be superfluous to make adjustments and make analysis taking into account today's realities. After all, both types of matrices are constantly being improved, getting rid of some shortcomings, or these disadvantages become less significant.

Which 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 based on the preponderance of the strengths or, taking into account the specifics, to decide which is better 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.

Advantages of IPS matrices

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

• Availability... Over the years, the technology has been massively mastered by many companies, making the mass production of IPS screens inexpensive. The cost of a screen for a smartphone with FullHD resolution now starts at about $ 10. Thanks to their low price, these screens make smartphones more affordable.
• Color rendering... A well-calibrated IPS screen reproduces colors with maximum fidelity. That is why professional monitors for designers, graphic artists, photographers, etc. are produced on IPS matrices. They have the widest color gamut so you can get realistic object colors on screen.
• Fixed power consumption... Liquid crystals that form a picture on an IPS screen consume almost no current, the main consumer is backlight diodes. Therefore, the power consumption is independent of the image on the display and is determined by the backlight level. Due to the fixed power consumption, IPS screens provide approximately the same autonomy when watching movies, surfing the web, writing communication, etc.
• Durability... Liquid crystals are almost unaffected by the aging process and wear and tear, so 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 after 5 years the screen almost does not lose its brightness.

Disadvantages of IPS matrices

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

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

• Low contrast... The contrast level of LCD matrices (about 1: 1000) is acceptable for a comfortable perception of the picture, but according to this indicator AMOLED is better than IPS. Due to the fact that the black is not very deep, the difference between the brightest and the darkest pixel in such screens is noticeably less than that of LED matrices.
• Long response time... The pixel response speed of IPS panels is low, about ten milliseconds. This is enough for normal perception of the picture when reading or watching 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 not without their drawbacks.

Benefits of AMOLED matrices

AMOLED technology is newer than IPS, and its creators have taken care of eliminating the disadvantages typical of LCD displays.

• Split Pixel Glow... In AMOLED screens, each pixel is itself a light source and is controlled by the system independently of the others. When displayed in black, it does not glow, and when displaying mixed shades, it may produce increased brightness. Due to this, AMOLED screens demonstrate better contrast and black depth.

• Almost instant reaction... The pixel response speed on the LED matrix is ​​orders of magnitude higher than that of IPS. Such panels are capable of displaying a dynamic picture with a high frame rate, making it smoother. This ability is a plus in games and when interacting with VR.
• Reduced energy consumption when showing dark tones... Each pixel of the AMOLED matrix glows independently. The lighter its color, the brighter the pixel, therefore, when displaying dark tones, such screens consume less energy than IPS. But in the process of displaying white AMOLED panels, they show a similar, or even greater than that of IPS, battery consumption.
• Small thickness... Since AMOLED matrices do not have a layer that scatters backlight light onto liquid crystals, such displays are thinner. 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 only curved) AMOLED matrices. This is not possible for IPS.

Disadvantages of AMOLED matrices

AMOLED-matrices are also characterized by shortcomings, and there is only one culprit for most of the troubles. These are blue LEDs. The development of their production is more difficult, and in terms of quality they are inferior to green and red.

• Blue or PWM... When choosing a smartphone with an AMOLED screen, you have to choose between pulse width control of brightness and blueness of light tones. This is due to the fact that with continuous light, blue subpixels are perceived more strongly than red and green ones. This can be fixed 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.

• Burnout blue... There is also a problem with the blue diodes. Their lifespan is shorter than green and reds, so color distortion may occur over time. The screen turns yellow, the white balance shifts towards warm tones, the overall color rendition deteriorates.

• Memory effect... Since miniature LEDs are prone to fading, areas on the screen that displayed a bright, static picture (such as a clock or a light-colored network indicator) may lose brightness over time. As a result, even if the element is not displayed, the silhouette of this element is visible in these places.

• PenTile... The PenTile structure is not a fundamental disadvantage of all AMOLED panels, but it is still characteristic of most of them. With this structure, the matrix contains an unequal number of red, green and blue subpixels (Samsung has half the number of blue ones, while LG has twice as many). The main motive for using PenTile is the desire to compensate for the disadvantages of blue LEDs. However, a side effect of this decision is a decrease in the clarity of the picture, especially noticeable in VR headsets.

Taking into account all the features of both types of matrices, it can be noted that IPS with high resolution is better if you are interested in VR and need maximum picture clarity. Indeed, in AMOLED, PenTile hinders the comfortable perception of virtual reality, and the PWM of the backlight so far neutralizes the instantaneous reaction speed. Also, IPS is better if you have to work more with light colors (web surfing, instant messengers).

AMOLED screens are the future, but the technology isn't perfect yet. However, you can safely buy a smartphone with an LED screen, especially if it is a flagship. Brightness, contrast, deep blacks and energy savings when displaying dark tones can overcome all the disadvantages of OLED.

The display is one of the most important parts of a smartphone that we most often pay attention to when using it. True, not when buying, it's so easy to get lost in the variety of types of matrices and the listing of screen resolutions. That is why we will tell you about the types of displays and their resolutions. The smartphone market has a huge variety of types of display matrices - TFT, IPS, AMOLED and others. We will focus on the most important ones.

TFT is a display based on thin film transistors. This technology was invented back in 1959 and has already become covered with dust and cobwebs. TFT displays no longer meet all the necessary quality criteria for screens and are installed only in budget smartphones. Now TFT is inferior to IPS and OLED in color rendition and contrast.

However, they have one advantage - a high (1 ms) response time. Although the average user does not see the difference between 1 and 3 or 5-7 ms, that finally buries the technology.

IPS (In-Plane Switching) is a technology that also evolved from LCD displays. In contrast to the same TFT (I hope you are not confused in terms yet?), IPS has a higher contrast and color rendering indices, as well as a wider viewing angle and reduced power consumption. However, IPS is criticized for oversaturation and insufficient saturation of the entire picture.

At the moment, IPS is perhaps the most popular technology for creating smartphones and tablets.

Retina is the marketing name for the above-described IPS technology invented by Apple. Displays of Cupertinos are distinguished by a high pixel density (about 300 per inch), which makes them practically indistinguishable on the matrix for the human eye.

In 2012, the company began introducing Retina displays in MacBook Pro laptops, and then new screens appeared in smartphones.

OLED and AMOLED

Organic light emitting diodes (Organic Light Emitting Diode) are widely used in the production of plasma panels, smartphones and tablets. Such displays are composed of thin sheets of electroluminescent material that produce their own light. The advantages of OLED over older technologies are lighter weight, no need for backlighting, increased viewing angle, brightness and contrast.

The main disadvantages of the technology are their high cost and short service life. Unfortunately, even in top-end flagships, OLED displays fade and fade after 2-3 years of use.

AMOLED (Active Matrix Organic Light-Emitting Diode) or Super AMOLED are the marketing names for LED panels by Samsung. In order not to boggle your head with unnecessary facts, just remember that these displays are more energy efficient and more expensive. The average eye won't tell the difference between AMOLED and OLED.

Display resolution

No matter how high-quality the display matrix is, a lot depends on its resolution. Resolution shows how many pixels are along the length and width of the display. The higher the resolution, the denser the pixels are on the matrix (PPI). We will tell you what resolutions are currently used in the mobile market.

HD (1280 x 720 pixels)

The basic resolution for smartphones, as a rule, is no longer lower than the indicator. All budget smartphones are equipped with HD displays, the PPI indicator in such devices fluctuates around 300 dpi. According to experts, the lower pixel density our eyes can already see clearly.

Full HD (1920 x 1080 pixels)

An indicator that is often common in sub-flags. For example, on smartphones with a 5-inch display, the PPI already hovers around 440 dpi. Full HD screens are equipped, for example, the flagships of 2016 OnePlus 3 and OnePlus 3T.

Quad HD (2560 x 1440 pixels)

Going further, with Quad HD, the pixel density on a 5.5-inch screen (a very popular option) rises to 538 dpi. For Full HD, for example, this figure will be only 400 dpi. In order not to get confused, you need to remember that Quad HD is often called 2K.

Ultra HD (4096 x 3840 pixels)

Highest display resolution available in the smartphone market today. Ultra HD resolution is often referred to as 4K. For example, the Sony Xperia Z5 Premium has a 5.5-inch display at 806 ppi - nearly three times that of HD panels.

Which display is better?

It is difficult to answer, because everyone chooses a smartphone based on their requirements and tasks. Objectively speaking, in most cases, a flagship with a Super AMOLED display and a 2K resolution will display a picture much better than smartphones with an IPS matrix and Full HD resolution. However, there are nuances.

For example, there is no point in overpaying for Super AMOLED if there is a more affordable smartphone with an OLED display nearby - you won't notice the difference, but you will lose money in money. Or it's crazy to take a smartphone with an IPS display and HD resolution, and then wait for it to display realistic photos taken with a professional camera. In any case, if you are serious about buying a smartphone and you have the opportunity to touch it in your hands before buying, then do so. And, best of all, take two or three applicants for a purchase in your hands, turn them on and compare them head to head.

In this article, we will find details about the structure of AMOLED screens, their advantages and disadvantages, as well as the differences between Super AMOLED and Super AMOLED Plus technologies.

AMOLED panels have become the new standard in the world of screen technology. Increasingly, such displays are used in flagship smartphones, other mobile devices, monitors and even televisions.

The technology was first used in the Samsung S8300 Ultra Touch mobile phone in 2009, but now it is being used by other manufacturers as well. So, last year, the Chinese brand OnePlus introduced its own development Optic AMOLED in the flagships OnePlus 3 and.

What is an AMOLED panel?

AMOLED stands for Active Matrix OLED. The peculiarity of this type of display is that each pixel is illuminated by a separate diode, so no additional backlight or liquid crystals are required.

The first is the cathode layer. Organic LEDs act as light-emitting elements, and an active matrix of thin-film transistors is used to control them. They determine the amperage that flows through each diode, hence the brightness and color of the pixel. Then the anode layer passes. Next is the substrate, which can be made of various materials such as silicone, metal, etc.

In AMOLED panels, the subpixels are arranged according to the PenTile scheme developed by Candice Brown Elliott. Each pixel contains five subpixels, which are staggered in color: two red, two green, and one blue in the center. This arrangement provides a high brightness display without increasing power consumption. In 2008, Samsung Electronics took over the technology and began using it in its products.

Super AMOLED

In 2010, Samsung introduced an improved version of the panel called Super AMOLED. Its main difference was the absence of an air gap between the sensor and the screen itself. This increased the brightness and clarity of the image, improved readability in bright sunlight and reduced the thickness of the display.

In early 2011, another improved version was released - Super AMOLED Plus. Unlike its predecessor, it uses the RGB color model instead of PenTile, which provides increased picture clarity.

Benefits of AMOLED displays

One of the main advantages of AMOLED is that the power consumption of the display directly depends on the brightness of the image. Thus, the screen requires less power to display dark tones. This results in deeper blacks as the black pixels are not illuminated at all. Samsung has taken advantage of the same advantage in Always On Display technology, which allows you to display the time, date and notifications on the lock screen without noticeable battery drain.

These displays provide a wider viewing angle (about 180 degrees) both vertically and horizontally. At the same time, brightness, contrast and color saturation are preserved.

AMOLED panels are thinner to fit into a slimmer and more elegant body. Also, the freed up space inside the case can be used for other important components, for example, a larger battery.

In addition, AMOLED screens have a wider color gamut, faster response times and higher contrast.

Disadvantages of AMOLED

As mentioned earlier, power consumption in AMOLED panels directly depends on the brightness of the picture. This means that more energy is required when displaying light tones.

Another weakness is the unreliable connections inside the shield. Even with the slightest damage or crack, the display can completely fail. With a slight depressurization, the screen begins to fade gradually and stops showing after about two days.

With constant use in bright colors, the lifespan of such a panel will be noticeably reduced. Moreover, subpixels of different colors burn out at different rates, as a result of which the color rendition is disturbed. In addition, the maximum brightness of AMOLED displays remains lower compared to LCDs.

For a long time, one of the drawbacks was the high cost of production, which means that repairs, if necessary, were more expensive for users. However, with the advancement of technology, making AMOLED panels becomes cheaper.

Output

There is a lot of debate about the advantages and disadvantages of AMOLED panels. But it cannot be denied that such displays are the technology of the future, because more and more mobile manufacturers are beginning to move to a new standard, invest in its development, or even release their own versions of OLED screens.

If you are lucky enough to own a smartphone or other mobile device with an AMOLED display, we can advise you to stick to the dark design of the home screen and interface. This will reduce the power consumption of the screen and extend the life of the display. In doing so, be careful and remember that even with minor damage, the screen may fail completely.

Two things prompted me to create this article: numerous speculations by marketers and specialized journalists on the topic of screens; and a bunch of absolutely identical comment threads under smartphone reviews with absolutely identical discussions about which matrices are better. Usually, the hottest part is under the reviews of Chinese phones with OLED screens. I'm tired of fighting windmills, communicating with each reader individually, in this article I decided to dot the i's and dispel numerous myths about modern screens, looking ahead I will say that the emphasis will be on the opposition of IPS and AMOLED matrices. Most likely, most of you will not see anything new in what you have written, you will not receive sacred knowledge here, as well as tearing off the veils. I will talk about the obvious things that neither bloggers nor journalists want to talk about. The guide is designed for adequate thinking people, convinced fanatics can go about their business.

Definition of the term "screen"

Before getting to the point, you need to define the term screen and clarify its functionality. Wikipedia tells us that a screen or display is an electronic device designed to display information visually. If we try to give a less concise and more modern definition of a screen in terms of functional purpose and with an emphasis on consumer properties, then it will turn out something like this: a screen is a device whose task is to display all kinds of content and the user interface of operating systems and applications as accurately and in detail as possible. how the authors intended them. Physical resolution is responsible for “maximum detail”, otherwise: the number of the smallest screen elements (picture's elements) or just pixels (pixels), the higher the resolution, the better, ideally it should be infinitely large. For “as accurate as possible” such parameters as: color accuracy and contrast or the ratio of the lightest and darkest point on the screen are responsible. The secondary parameters that do not directly affect either the accuracy or the detail of the information display, but affect the consumer properties of the screen, include: maximum brightness, picture distortion when the gaze deviates from the perpendicular, reflection coefficient, picture refresh rate, response time, energy efficiency and some others ... Standing apart is such a parameter as color gamut - the most important parameter for professional monitors and practically meaningless for devices intended for content consumption. But it is the color gamut that has been the subject of a lot of speculation on the part of mobile gadget manufacturers in recent years. Let's clear up this muddy topic before moving on.

What is color gamut and why is it the subject of much speculation

You need to start with the fact that any image when captured and saved to the memory of a photo or video camera is encoded. Artificially created pictures and clips, as well as parts of the graphical user interface of operating systems and applications, are encoded in a similar way initially. In both cases, color information is represented using a color model - a special mathematical tool for describing color using numbers or, to be precise, coordinates. The most common is a three-dimensional RGB model, in which each color is described by a set of three coordinates responsible for one of the colors: red, green and blue, the displayed hue depends on the brightness ratio of each component. Modern screens are capable of displaying only a part of the spectrum of colors and shades visible to humans, the color gamut literally means how large this “part” is. Due to this limitation, a person is forced to create standards for representing the color spectrum based on the capabilities of existing screens. So in 1996, to unify the use of the RGB model in monitors and printing, HP and Microsoft developed the sRGB standard, which used the primary colors described by the BT.709 standard that was widespread on television and gamma correction designed for monitors with a cathode ray tube. It is important to understand that such unification allows, albeit with some reservations, to ensure that the creator and the consumer of content on their screens will see approximately the same thing. Subsequently, the sRGB standard has become widespread in all areas of content production, including in the field of creating Internet sites. Of course, there are other standards for representing the color spectrum, for example, Adobe RGB, the color gamut of which is much wider, but today the vast majority of content is encoded in accordance with sRGB.

What happens if sRGB content is viewed on a wider gamut screen without adaptation? The sRGB space coordinates will be transferred to the color space coordinate system of such a screen, as a result of which the colors will appear more saturated than they actually are, in some cases the shades will be distorted so much that orange turns red, lime green, and cyan blue. Conversely, if content with a wider color gamut is viewed on an sRGB screen, shifting the coordinates will cause colors to appear less saturated than they should be.

We all know that the screens of most modern flagship smartphones have an extended color gamut relative to sRGB, how does this affect their consumer properties? If it is an android smartphone or tablet, then there are three options. At best, the shell settings will have preset color profiles, among which there is one that brings the space to the sRGB standard, for example MIUI or the shell from Samsung. But, even in this case, the application of profiles “on the fly” is not possible, and the user will have to choose between extended color gamut and correct color reproduction. The second option is when the system does not have built-in profiles, but in the developer settings you can activate the sRGB mode, for example, this can be done on Google Pixel and OnePlus 3T smartphones. Unfortunately, the operating system's graphical interface becomes faded when sRGB is activated, as it is encoded according to the color gamut of their screens. In the third worst case, the user will not find any profiles in the system and will not receive any choice, respectively, he will only have to enjoy oversaturated colors. But in personal computers on Windows and MacOS, there is no such problem, since both systems not only support color profiles, but can also “on the fly” convert colors from one space to another, that is, regardless of what content and on what screen will be displayed, the user, with some reservations, will see the colors as the author intended. IOS has a similar color profile management system. Manufacturers, whether for the sake of beautiful numbers on the specifications page, or just for the sake of it, continue to install screens with extended color gamut in the flagship models of IPS and OLED, despite the fact that there is no need for this, since 99% of the content complies with the sRGB standard and the situation is unlikely to change radically in the near future. The tasks that such screens can perform in devices created for the consumption of content simply do not exist. All of this would make some sense if Google added color profile management to Android, as Apple did, but at least in 2017 we won't see that. The irony is that the problem was created from scratch, and no one is in a hurry to solve it.

Liquid crystal screen: working principle; Advantages and disadvantages

Twenty years ago, screens based on a cathode ray tube were installed in most monitors and televisions, soon they were replaced by liquid crystal screens or LCD (liquid crystal display), which over time received several branches of development and today there are three technologies for the production of liquid crystal matrices screens: TN, MVA and IPS, the latter, due to a successful combination of advantages and disadvantages, has become dominant in the segment of mobile technology. The principle of LCD operation is simple, depending on the production technology, some details may vary, but a typical matrix includes a backlight lamp and six other layers. First behind the lamp is a vertical filter that polarizes the light accordingly. It is followed by two layers of electrodes with a layer of liquid crystals located between them, the voltage applied to the electrodes orientates the crystals and they refract the light so that it passes or does not pass through the next layer - a horizontal polarizing filter. The last is the color filter - red, green or blue. Liquid crystal screens are lighter, more compact and more energy efficient than their predecessors, but they also have a number of serious drawbacks, in particular, low contrast and black depth, even limited color gamut potential, which depends on the imperfection of backlight lamps. In addition, brightness and contrast performance may deteriorate if the screen is not viewed at a right angle.

OLED Screen: Advantages, Disadvantages, PWM, Pentile

Relatively recently, LCD has a serious competitor - these are active matrix OLED screens or AMOLEDs. Such screens are fundamentally different from LCDs in that the light source in them is not a backlight, but each subpixel separately, which gives AMOLED many advantages over liquid crystal screens, the main ones of which are: almost infinite contrast; less power consumption when displaying images with a predominance of dark tones; potentially wider color gamut; and smaller dimensions. The first AMOLED screens, in addition to advantages, had significant disadvantages, including: inaccurate color reproduction; fast burning out of LEDs; high power consumption when displaying images with a predominance of light tones; flickering due to pulse width modulation; and most importantly, the high cost of production. Over time, most of the shortcomings were overcome or minimized, except for PWM, which to this day is the Achilles heel of technology. Pulse Width Modulation or PWM is one way to adjust the brightness of LEDs, the side effect of which is that the screen flickers at some frequency. Most people are not susceptible to this kind of flickering, but for some users, PWM can cause rapid eye fatigue and even headaches. It is important to note that the flickering effect is completely absent at brightness values ​​close to maximum and begins to appear at a brightness level of 80% and below.

It is impossible to ignore the topic with the organization of subpixels in OLED screens, the fact is that in most AMOLED matrices, subpixels are arranged according to the RGBG scheme, when a pixel does not consist of three subpixels as in a typical LCD screen, but of four: red, blue and two green, this scheme is also called Pentile. The manufacturer (Samsung) considers the physical resolution of such screens to be exactly two times less by the number of green subpixels, red and blue subpixels in the matrix. Obviously, you need at least three full subpixels to get a hue. Thus, the effective resolution of such screens is not equal to the nominal resolution specified in the official specification. For example, for a QHD screen, the nominal resolution is 2560 * 1440 pixels, the resolution based on the number of red and blue subpixels will be approximately 1811 * 1018:

The effective resolution of such a matrix, taking into account the clever interpolation algorithms embedded in the screen controller, is somewhere between 1811 * 1018 and 2560 * 1440, we can assume that it corresponds to the FullHD resolution in RGB matrices. It may very well be that it is for such a match that Samsung has chosen QHD resolution for its flagship smartphones for many years in a row.

A detailed comparison of IPS and AMOLED on the example of the screens of smartphones iPhone 7 and Galaxy S8

Now, after we have learned all about the characteristics of screens and about the features of different types of matrices, we can move on to the main question: which technology is better? I am sure that it is correct to try to answer this question by comparing the best AMOLED and IPS matrices available today, namely the screens of the Samsung Galaxy S8 and Apple iPhone 7 smartphones. Since I have not yet acquired test equipment, I will analyze the test results taken from an authoritative resource. Let's start with the resolution, the Galaxy S8 screen has 2960 * 1440 pixels, the guaranteed effective resolution will be 2094 * 1018, and the guaranteed effective pixel density is 403 per inch. The iPhone 7 Plus has a nominal effective resolution of 1920 * 1080, and an effective pixel density of 401 per inch. There is an obvious preponderance in favor of the screen from the Korean vendor. The resolution of both screens is enough for everyday use and not enough for comfortable operation with virtual reality helmets. Moving on to accuracy, the Galaxy S8's contrast ratio is nearly infinite. The iPhone 7 has a declared contrast ratio of 1400: 1, the actual one is slightly higher - 1700: 1, this contrast is more than enough for comfortable viewing of content. It turns out that the screen of the Galaxy S8 is ahead in this parameter as well. In terms of color accuracy, both smartphones showed virtually the same results, color errors in the Galaxy S8 and iPhone 7 can be safely ignored. You can see the most important secondary characteristics in my opinion below:

As for the color gamut, then the iPhone 7 is ahead, since it can display the colors of the DCI-P3 space or 126% of the sRGB field, while the user does not need to sacrifice color rendition, the content is displayed based on the color profile embedded in it. The Galaxy S8's screen has an even wider color gamut - about 142% of the sRGB field, but does not have color profile management, driving the user into a corner, that is, in Basic mode, which corresponds to 100% of the sRGB field.

So what's the bottom line? If we consider screen technologies in isolation from the final product, then AMOLED today surpasses IPS in almost everything, although it still has problems with PWM and high power consumption. There is no doubt that OLEDs are the future. Unfortunately, due to the limitations of Android, their potential has not yet been fully revealed. When comparing ready-made solutions in the face of Galaxy S8 and iPhone 7, it is obvious that the latter is slightly superior due to the honest DCI-P3 and other reference parameters. I want to warn you against projecting the results of the above comparison on absolutely all IPS and AMOLED screens. There are a lot of good, average and bad matrices on the market, and each case needs to be dealt with separately. In this we will be helped by Internet publications focused on technical detail and reliability, to such publications I would include the already mentioned, anandtech.com and some other sites from Russian-language sites - ixbt.com.

Perhaps you shouldn't take the consumer properties of screens too seriously, because the factor of subjective perception is almost always superimposed on objective information. For example, in Southeast Asia there are a lot of people who like unnatural oversaturated colors, in our country there are also a lot of such people. On the other hand, broadcasting information poured into the ears of marketers in numerous discussions under reviews on YouTube is at least strange. In the end, I'll be Cap and give a couple of banal advice: don't stop thinking and be critical of any information you get from brand representatives and the media, be able to analyze data and check facts, or just read resources and watch bloggers you can trust.

A fairly well-established product in the IT technology market is the flagship with amoled type monitor.

AMOLED display

AMOLED technology is the brainchild of the world famous Samsung company. The invention won the love of consumers, thanks to which the manufacturer tries to improve it all the time.

First, let's see, amoled display, what is it? This is an abbreviation of the capital letters, which when decoded are as follows: Active Matrix Organic Light-Emitting Diode.

A technique that allows you to create monitors for televisions, mobile phones and computers.

It is based on the use of organic light-emitting diodes, as parts that emit light, and an active matrix, which consists of thin-film transistors.

Interesting in technology is a way to create black.

If it is necessary to generate it, the LEDs simply stop working, and this makes it possible to appear in a truly saturated, deep black color. When it is present on the monitor, a decrease in the power consumption of the phone is observed.

All pictures look much more attractive on the screen. Color reproduction is bright and rich. Therefore, the models hold the lead in the market along with IPS.

Phones with AMOLED display

Phones with amoled display do not lose their relevance for a long time. They have won their trust and now even practice setting in a budgetary model.

Users of such gadgets are satisfied with the color scheme provided by the developers and the devices themselves in general.

Popular models with such a screen include:

Pros of AMOLED

Of course, phones with such a display are very high-status. Among their advantages is the width of the screen, in which the corners do not bend and the picture is shown in full. Also, excellent contrast.

Monitor matrices are presented in a very rich color. Black looks perfect.

When you look at such a display, you get the feeling that the picture is not in it, but on the surface. According to consumer reviews, this increases the enjoyment of using the gadget.

Disadvantages of AMOLED

To date, the quality of screens made on the basis of amoled technologies has improved so much that consumers simply do not find any negative aspects of the product.

One bad trend is still visible. The most negative thing is that health problems appear.

Even with a short viewing of multimedia files, eyes begin to fatigue, and over time, vision deterioration occurs. From fatigue of the eyes, the sharpness of vision is lost.

The color pictures on the screen are very bright. Not everyone can adapt to such a strain of the eyeball. At first, I like the brightness, but it has a destructive effect on vision.

From the side of science, it was not possible to confirm such data. After all, you need to collect a certain number of people, conduct research and draw conclusions based on statistical data. We provide information that only a few users have shared on the Internet.

Many of them wrote that after buying a phone with such a display, their eyes began to get very tired, and they had to buy special drops. Or one hundred percent vision has deteriorated in a short time.

Among the disadvantages of this technology, you can also highlight:

1 You need to be very careful with the phone display. If you damage it anywhere, and even the slightest air gets inside, the screen will instantly fade. Within one or two days, your mobile device will become unusable due to the fact that the monitor will stop showing at all. From the point at which the depressurization has occurred, a black spot will appear and in a short time will expand to the entire surface.

1 The connections under the shield are extremely loose. At the slightest mechanical damage, such as a crack, the monitor becomes unusable. He doesn't show.

Smartphones with AMOLED display

Smartphones with amoled display have been on the IT market for a long time. They are known to a large number of users and have managed to gain recognition for the brightness of their color rendition.

Many manufacturers are increasingly turning to this method when creating smartphones.

So, phones Meizu Pro 6, Yota YotaPhone 2, Huawei Nexus 6P, Highscreen Bay, Lumia use amoled screens in their models.

The Microsoft Lumia 950 Dual SIM uses a 5.2-inch display created using this design methodology. Customer reviews are the most positive.

Photos and videos can be viewed freely even in the strongest sunlight.

Highscreen Bay is known for being able to reproduce even the smallest details in an image thanks to this screen technology. This is due to the excellent quality of the AMOLED matrix.

The Meizu Pro 6 phone is also equipped with a Super AMOLED matrix. His pictures are bright and clear.

Model Yota YotaPhone 2 is equipped with a 5-inch screen and AMOLED matrix.

Super AMOLED

The technology appeared in 2010. It is much better than its predecessor.

The benefits are noticeable:

• More brightness. The color gamut has become twenty percent richer.
• The viewing angle has changed. It becomes 180 degrees and the advantage is that the image remains clear and of high quality, not only for the person who is looking at the screen located directly in front of him, but also for everyone else, at any distance.
• Energy consumption has decreased by twenty percent.

Energy reserves are an ongoing problem for smartphones. It's good if the phone has enough charge until the evening, or even less. So here's a new technique slightly increased the operating time of the device.

• The phone is now more durable. New models are manufactured without a built-in air cushion. This makes it possible to make the devices much stronger, and accordingly, their service life increases.

For example, when there is a lot of white color on the screen of the phone with the display in question, then the energy goes twice as much. This does not happen in IPS phones..

When working with a black screen, the energy consumption figures are approximately the same. During normal operation of the device, IPS also dominates in the energy charge.

For whom it is more convenient, but when the phone, which has a built-in amoled display, is running, the brightness goes off scale. It gets in the way a little.

And with prolonged use, the eyes hurt and dry out. In IPS, with a more gentle color gamut, there are no such problems.

However, if you examine the speed of the phone's response to your manipulations, IPS phones are much slower to respond.

On the positive side, the screen reproduces more natural colors. But when photographing on the sunny side, the device clearly lacks brightness.
