The best smartphone display. Comparison of screens of flagship smartphones. What is an engineering menu

How to choose from the diversity of modern smartphones what is suitable for you? Today the Bad-Android team has prepared material with useful advice On the topic of selection of displays.

How not to overpay for the device? How to deal with the type of display what to expect from him?

Types of Matrix

In modern smartphones are used three Main types of matrices.

The first one called is based on organic LEDs. The remaining two types are based on liquid cristics - IPS. and TN + FILM..

It is impossible not to mention the frequently found abbreviation TFT.

TFT. - These are thin-film transistors that control subpixels of displays (subpixels are responsible for three main colors, on the basis of which "full" multicolor "pixels are formed, which we will talk a little later).

Technology TFT. Applied in all three Types of matrices listed above. That is why frequent comparison TFT. and IPS. It is absurd essentially.

For many years, the main material for TFT matrices was amorphous silicon. On the this moment The improved production of TFT matrices in which the main material is launched polycrystallic siliconsignificantly increasing energy efficiency. Also diminished the size of the transistors, which allows to achieve the highest indicators pPI (pixel density).

So, with the base of the matrices figured out, it is time to talk directly about the types of these matrices.

TN + FILM Matrix

It is these matrices that appeared first in smartphones. At the moment, they remain the most primitive and, accordingly, cheap.

Advantages:

    Available cost

Disadvantages:

    Small viewing angles (maximum 60 degrees)

    Inverting the image Even with small tilt angles

    Low contrast

    Scooty color reproduction

Most manufacturers practically refused to use this type Matrices due to too much shortcomings.

IPS matrix

At the moment, this type of matrices is the most common. Also, IPS matrix are sometimes denoted by abbreviation SFT.

History IPS.-matizals originates a few decades ago. During this period, many different modifications and improvements have been developed IPS.- Dysplays.

When listing the deficiencies and advantages of IPS, it is necessary to take into account the specific subtype. Summarizing for List strong Parties IPS Take the best subtype (respectively, the most expensive), and for the minuses we will keep in mind a cheap subtype.

Advantages:

    Excellent viewing angles (maximum 180 degrees)

    High-quality color reproduction

    Ability to release high PPI displays

    Not bad energy efficiency

Disadvantages:

    Flowing Pictures for Display Talls

    Absolvement is possible or vice versa. Insufficient color saturation

Amoled Matrix

The matrix provides the deepest black color, relatively with two other types of matrices. But it was not always so. The first amoled matrices have implausible color reproduction and insufficient color depth. The acidity of the picture was present, too intense brightness.

Until now, due to internal incorrect settings, some displays for perception are almost identical to IPS. But B. Super-amoled. Displays All flaws successfully fixed.

With the list of advantages and disadvantages, take the usual amoled matrix.

Advantages:

    The highest quality picture among all existing types of matrices

    Low power consumption

Disadvantages:

    Occasionally occurring unequal life of LEDs (different colors)

    Need to carefully set up amoled display

Let's summarize the result. Obviously, the image of the image of the matrix is \u200b\u200bleading. It is AMOLED displays installed on the topmost devices. In second place are IPS. Matrices, but with them should be attentive: manufacturers rarely indicate the subtype of the matrix, namely, this plays a key role in the final level of the image. Unambiguous and solid "no" should be said to devices with TN + FILM. matrices.

Subpixels

The defining factor in the final quality of the display is often hidden Displays characteristics. At the perception of the image, strong influence is provided subpixels.

In case of LCD. Situation is quite simple: each color ( RGB.) The pixel consists of three subpixels. The form of subpixels depends on the modification of the technology - subpixel may have a "check mark" or a rectangle.

In the implementation of displays in terms of subpixels, everything is somewhat more complicated. In this case, the source of lighting is the subpixels themselves. As you know, the human eye is less sensitive to blue and red, in contrast to the green. That is why the repetition of the IPS patter subpixels would significantly affect the quality of the picture (naturally, in worse side). To preserve the realism of color reproduction, technology was invented.

The essence of the technology is to use two pairs of pixels: RG (Red-Green) and BG (Blue-Green), which, in turn, consist of the corresponding subpixels of the respective colors. A combination of subpixels forms is applied: green is elongated, and the red and blue are almost square.

The technology was not too successful: the white color was frankly "dirty", and the jazbins appeared at the joints of different shades. With a low indicator pPI The grid of subpixels became visible. Such matrices were installed on a number of smartphones, including flagships. The last flagship, which "was lucky to" get a pentile matrix became Samsung Galaxy S III..

Naturally, it was impossible to leave the situation with the poor-quality implementation of subpixels in the same state, so it was soon produced upgrade above the described technology that has received a prefix Diamond..

With the help of increasing PPI Diamond Pentile. allowed to get rid of the problem with the served boundaries between the colors, and the white became much more "cleaner" and more pleasant to the eye. And it is this development that is installed in all Samsung flagships, starting with Galaxy S4.

And here IPS.- Satisfy, although they are considered generally weaker, 'oivans, however, they never encountered such problems.

What conclusion can be done? Be sure to pay attention to the number pPI In the case of the acquisition of a smartphone with a stem. High-quality picture is possible only with the indicator from 300 ppi. But S. IPS. There are no matrices of such strict restrictions.

Innovative technologies

Time does not stand still, talented engineers continue to work painstakingly on improving all the characteristics of smartphones, including over the matrices. One of the latest serious developments is technology. OGS..

OGS. It is an air layer between the screen itself and the projection and capacitive sensor. In this case, the technology has justified the expectations of 100%: the quality of color reproduction, the maximum brightness and viewing angles have increased.

And over the past few years OGS. So I was introduced into smartphones, which is not to meet the implementation of the display with a "hamburger" with a filling from the air layer, perhaps on the simplest devices.

In search of optimization of displays, designers stumbled upon another interesting opportunity to improve the picture on the phones. In 2011, experiments started form Glass. Perhaps the most common form of glass among unusual 2.5d. - With the help of begnes, the edges of the glass are becoming smoother, and the screen is voluminous.


Company HTC released smartphone SENSATION.The glass of which was concave in the center of the display. According to HTC engineers, thus increases scratch and blows. But the glass concave to the center did not receive.

The concept of bending the display itself was more popular, and not just glass, as was done in. One of the side lights of the display received a curved shape.


Quite interesting characteristicon which attention should be paid when buying a smartphone is sensor sensitivity. A sensor with increased sensitivity is installed in some smartphones, which allows you to fully use the display even in conventional gloves. Also, part of the devices is equipped with an inductive substrate to support styluses.

So for lovers to alternate on the frost or use the stylus, the sensory sensor is uniquely useful.

Famous truths

It is no secret that screen resolution also strongly affects the end level of the image. Without unnecessary comments, we offer you a table of conformity to the diagonal of the display and permissions.

Conclusion

Each matrix has its own characteristics and broken characteristics. You should be careful with debries, rather, with an indicator of PPI pixel density: if the value less than 300 ppithen the quality of the pictures of you frankly disappoint.

For IPS.-matiza is important subtype, and depending on the subtype, the cost of the smartphone is logically increasing proportionally.

Curved glass 2.5d. significantly increase the attractiveness of the picture, as well as technology OGS..

The question of the size of the display is purely individual, but with multiworm "shovels" will be relevant to the high resolution.

We wish you pleasy Shopping, friends!

Stay with us, there is still ahead lot Interesting.

Day after day, many of us, tens of hours staring at the screens of their mobile devices. The most important display parameter is brightness, affects not only the rate of energy consumption of the battery of our smartphones, but it is also one of the most common causes of eye fatigue. Today we have prepared a list of six Android Appsthat will help you prevent eye fatigue and extend the life of your phone or tablet battery life.

Cobrets (Reducing the Configurable Brightness Preset) is a free application that allows you to switch between different brightness presets using a small (1 × 1 size) widget on the main screen. Cobrets has several predefined brightness modes: minimal (8%), Quarter (25%), medium (45%), maximum (100%), automatic, night, and day.

You can edit the minimum brightness values \u200b\u200bfor modes: minimum, Cuarter, medium and maximum. Auto mode Use Android automatic brightness settings. Night mode Sets the zero brightness value and imposes a black translucent filter to the screen area, so you get the level of brightness even lower than the default value in the system. Finally, the day mode uses a yellow filter imposed on the image on the display to facilitate the load on your eyes. CobretS allows you to manually change the brightness level and parameters of the filters used, including filter colors and opacity levels. Cobrets gives you the opportunity, directly, enable or disable any of these modes, so you do not have to switch between all.

In some cases, when the display of your device is faulty, you can use this application to adjust the displayed colors. However, given the prices for displays, it is possible to change it easier. For example, the price of the original display for Prestigio from Mobilife is quite democratic. Replacement display, you can produce as in service centerand independently.

Intellisccreen is a free application that allows you to configure the time of turning off the screen depending on the position of the device, the conditions of lighting and currently operating applications. First, the application will ask you to set the normal timeout value of the screen, which will be used by default. With Intellisccreen, you can set any time interval, even exotic values, for example, 2 minutes of 15 seconds. Then you can set individual rules for applications. It is possible to keep the screen always enabled, while any application works in the foreground, or set the screen shutdown time for each application.

Intellisccreen also allows you to use the device sensors to control the screen timeout. You can completely disable the timeout when you hold the device in a certain position (portrait or landscape orientation), which is determined using the accelerometer. You can also use the light sensor. This allows you to automatically turn off the screen when you put the device in a dark place (for example in your pocket), and turn on the screen when the device drops on the device. True This option is only available if you decide to update Intellisccreen to premium version (€ 1.99).

Finally, you can choose when your settings will be applied: always or only when the device is fixed in the automotive, desktop docking station, or connected to the charger.

Lux Auto Brightness is a popular Android application that allows you to easily adjust the screen brightness to the optimum level, thereby reducing the eye load and keeping the battery charge. LUX AUTO BRIGHTNESS is a small pop-up window with a slider that is used to adjust the brightness.

Most an interesting feature LUX AUTO BRIGHTNESS is the ability not only to create abstract profiles, such as "night" and "day", but setting the display parameters, respectively, a certain, actual ambient lighting intensity. By default, LUX Auto Brightness will adjust the brightness level only at the time, the awakening device, so you will not be distracted by changing the brightness of the screen. However, you can change this behavior and choose one of several setup modes: ascending, periodically dynamically or manually.

LUX AUTO BRIGHTNESS Available in two versions. Exists free version Lux Lite, which includes the most important use methods. If you like the application, you can purchase full version Lux Auto Brightness for $ 3.80.

Night Mode is a very simple application that will override the settings of the display of your system, so you can reduce the screen brightness below normal level. Night Mode uses filter overlay, which acts as a dimmer to darken the screen, so that it will be comfortable for the eye. This is especially useful when you use your phone in low illumination conditions, for example, in a movie or theater. Night Mode is free app, without any built-in advertising.

Twilight is an application that adjusts the color temperature of the display of your device according to your current location and time of the day. Twilight is based on the idea that the excessive exposure to bright blue light can cause the secretion of the melatonin hormone at night, thereby causing the inability to fall asleep. Bright blue light sources, such as natural sunlight or LED displays, inhibit the creation of melatonin in the brain, which signals the body about the beginning of the day. The program filters the blue spectrum of the display of your mobile phone or tablet and protects your eyes using a soft red filter. The application allows you to configure the color temperature and intensity, as well as the level of screen illumination.

Velis Auto Brightness is an application that gives you complete control over the settings of the automatic brightness level on your Android device. When you start Velis Auto Brightness for the first time, a simple seven-step vizard will help you run the initial setting.

The main screen of the program displays a custom-made curved brightness graph of the surround light by the coordinate axis x, and the brightness of the screen on the Y-axis. Drag the red marker to change the screen brightness at different levels of external lighting. You can save several settings at once, like different profiles.

There are many other parameters that you can configure using Velis Auto Brightness. You can create a list of applications when you work. existing settings, change sensitivity sensors and so on. Some additional functions (Support Tasker, Widget) are available as premium content through the order within the program.

The screen is a smartphone face, it takes most of the front surface, necessary to control the gadget and perception of all information. List all the display features, probably, it would be superfluous, as each of us perfectly understands how much this element is important in the smartphone. On improving displays, manufacturers spend millions of budgets, pleaseing users with a growing resolution, improved color reproduction, new technologies and constantly expanding viewing angles. If among more or less expensive smartphones to find a model with a decent display is easy, then in the budget segment, as a rule, screens are presented with the minimum necessary for modern parameters (IPS technology, HD resolution). Do not argue - this will be enough for this very much, but our goal today is to find interesting not dear smartphones With a good screen, preferably Full HD.

Let's start with the announcement of variables. We will understand what are the display parameters to pay attention to:

  • screen diagonal. Its size. A large display allows you to more comfortably read and watch movies, but too big will turn the smartphone in the shovel. The diagonals of the screens of modern smartphones start from 4.7 inches, and that such find difficult. The most popular format is not even 5 inches, but 5.5 dm. There are smartphones with a diagonal of 6 dm and even 6.5 dm. Here everyone chooses himself for themselves, but before buying it does not prevent Her apparatus in the hand to understand how convenient will it be used. The budget sector presents smartphones with a different diagonal;
  • screen resolution - The number of pixels that form the image. Than they are more, the more high-quality and solid will be a picture, and the smaller the individual points of the image will be. Manufacturers indicate the number of pixels horizontally and vertical in a similar form 320 * 480. Permission for budget smartphones HD. – 720*1280 And it is quite enough if the diagonal of the screen is 4.7 inches and less. Screens with a resolution of 540 * 960 are still found in the budget sector, but with a diagonal of 4.7-5.5 inches, individual pixels are very well noticeable, so such models do not even consider. If the diagonal is 5 inches and more, it is better to look aside FullHD screens, their permission 1920*1080 . They allow you to create an ideal high-quality picture;
  • pixel density - This is an indicator depending on the diagonal and permission. It defines how many pixels of the image fall on an inch screen. Proved that at a density of 300.pPI and above our eyes can not distinguish individual components (pixels) and perceives the picture holistic. Apple, for example, is why it does not use the resolution in its smartphones above something that is capable of providing 300 ppi with a certain diagonal. The remaining manufacturers went on otherwise, offering pixel density in 500 ppi and more, which is achieved by using high-resolution screens (2K or QHD - 1440 * 2560, 4K or UHD - 3840 * 2160). What is this, advertising move or care of the user, to solve you, and we advise you to pay attention primarily on the pixel density indicator, and not permission: if it is 300 ppi and more, we can safely take. True, with the rapid growth of diagonals of the screens, find an inexpensive smartphone with such an indicator is not easy. Simple rule: if a diagonal is less than 4.7 dm, permission can beHD.if more is desirableFULL HD.and they are already in budget devices;
  • screen type. Let's not go into the features of building an image by each type of screen and immediately proceed to the facts. TN.- Satisfy- The cheapest, not very contrasting, have bad color reproduction and small viewing angles, but cheap. Today is practically not used. IPS.- Satisfy - Standard for many smartphones. Such a screen gives good color reproduction, viewing angles and contrast, but consumes more energy than Amoled.-the matrix. The latter due to the characteristics of the structure does not need additional backlight, they give the deepest black color, excellent color reproduction, consume minimum of energy. Previously, Amoled was put only in the most expensive smartphones, but today everything has changed somewhat.

It is better to take a smartphone with a screen performed by oGS technologywhich provides for lack of air interlayer between the sensor and the display. This allows you to achieve better color reproduction, wider viewing angles and screen compactness. True, if the glass breaks, you have to change the entire screen block. Today, most screens of smartphones are made using OGS technology.

Not superfluous in the smartphone will be protective glass and oleophobic coating. The latter allows much easier to maintain the screen in its pure form. Fashion trend of this year - warmless screens - selected and to budget smartphones. It is unusual to use such devices, but with standard sizes of the smartphone, you can get a screen with an enlarged diagonal.

Now let's go to the most interesting and place of smartphones from the most cheapest to a little less cheap. All of them will cost you to $ 130-150.

The smartphone came out in 2015 and at that time was premium. Today it is still selling and in demand, and if you get a discount, you can buy the device at all for $ 85-90. Gadget received metal case, fingerprint scanner And middle filling, memory can be expanded. The picture quality is satisfactory, but in the dark leaves much to be desired. The pride of the model is a screen, large, with good resolution and wide viewing angles, processes 10 simultaneous touch. At the minimum level of brightness, the display allows you to comfortably use it at night, but if you consider it in detail the device, you can find fault with the color rendition and the absence of oleophobic coating. The rest of the gadget is not bad for its value.

Oukitel U20 Plus.


When buying in Russia, the device will cost $ 110-120, it can be found even for $ 100, but when ordering from China, you can save a couple of dozen dollars. The minimum price for it is $ 88. The smartphone itself began to sell this year, he immediately surprised with his flagship ships. The manufacturer packed the device into a pretty case with 2,5 D.-EkranSupplied fingerprint Scanner and Double CameraWhat is even rare in the budget segment. The big screen with Full HD resolution turned out to be very and very successful: the color rendition is close to the most natural, brightness is adjustable widely, and even under the right sunlight information on the display remains readable, the viewing angles are wide, the screen processes up to 5 simultaneous touches. It is possible to set up color reproduction and other display parameters for yourself. For other parameters, this is an ordinary smartphone whose capabilities, however, with the head of the average user.

Leagoo Kiicaa Mix.


The device came out literally the other day and became one of the first budget examine Smartphones . Earlier similar devices Already were presented in an inexpensive segment, but the screens left to desire the best. The company suggests at a price of $ 105-120, an excellent shonderphone, and this is the modern trend. The screen takes almost the entire front panel - a small space remains only downstairs, where it is located fingerprint's scanner. Screen performance on height: Brightness is adjustable in a wide range, the device will be convenient and at night, and with bright light. Add here excellent performance, decent memory reserve, double chamber with good photo quality, and you can probably get the most interesting offer in this price categoryBut without nuances did not cost.

To expand the borders of the screen, the designers had to abandon the light sensor and approximation, Eyeball frontal chamber To transfer to the lowest, and the conversational speaker is to the top end. Such a solution causes a lot of inconvenience, at least at first. But the colloquial speaker is turned on along with the usual sound during the playback and something like a stereo is obtained. Another unpleasant feature - to connect headphones here is used USB Type-C. But the device is light, cheap, has a large screen and small size, comfortably lies in the hands and flies in most applications.

Xiaomi Mi4.


The screen of this smartphone got gorilla Glass III protective glass and oleophobic coating, Through which the finger slides easier, and all the pollution is erased easier. With a 5-inch Full HD diagonal, the resolution allows you to create an incredibly clear picture. By the way, it is only a fact that a 5 inches screen is used in the device - this is an obvious plus for those who are looking for a more or less compact smartphone. Display recognizes up to 10 touches, has decent viewing angles, an impressive stock of brightness and anti-reflective coating. This is one of the best screens In the segment, so you can forgive the device the fact that he came out in 2014 and then, by the way, was the flagship. Until now, the model is actively sold in stores. The smartphone is productive, the camera module from Sony allows you to make excellent pictures. There is here function fast charging. Minus - no slot for memory cards.

Prestigio Grace.


Let it not powerful smartphone our ranking, but he boasts Amoled.- SatisfySo quality image is very high. The small, it would seem, the battery capacity will be enough for the average work of 1-1.5 days, as the screen is economical here.

Alcatel Pop 4S 5095K


An interesting inexpensive device, which will be interesting to those who are oriented when choosing the manufacturer's name. The company is known, regularly produces new models, and this time presented a good budget apparatus with a decent screen and middle stuffing. Device Fishka - availability fingerprint scanner. Stock technical capabilities It will be more than enough to most users.

Leagoo T5.


The device surprises, first of all, a margin of memory, and then the display parameters. If you consider the price, we get a very decent device. Among the advantage metal case, double camera, Fingerprint's scanner. As a result, we get a very solid apparatus for an indecently low price for it, however, it will have to be ordered from the Middle Kingdom.

Leeco LE S3 x522


Smartphone made in metal building, Equipped with excellent screen with protective glass. To the picture that the device gives out, it is difficult to complain even the most pedantic user. Many experts say that only flagship devices can compete with this screen, so the device can be called the best inexpensive smartphone with a good screen.

For other parameters, this is a very decent smartphone. He is smart, got a very good camera and sound, though from the usual headphone jack here refused, replacing it on USB Type-C. When conducting different shares, the device can be bought for $ 120.

Meizu M5 Note.

Sympathetic all-metal smartphone Completes our rating. Externally, it resembles a device much higher price category. The screen has become proud device, it is juicy, bright and has extremely wide viewing angles. there is oleophobic coating. Praise the device for high performance, not bad autonomy and functional shell. The camera is medium, as in many Meizu, and the rest is all very good. If you get per share, you can buy a device somewhat cheaper.

The technologies of smartphone displays are not standing in place, they are constantly being improved. Today there are 3 main types of matrices: TN, IPS, AMOLED. Often disputes go about the advantages and disadvantages of IPS and AMOLED matrices, their comparisons. But TN screens are not in fashion for a long time. This is an old development that is now practically not used in new phones. Well, and if used, then only in very cheap state employees.

Comparison TN Matrix and IPS

TN matrices appeared in smartphones first, so they are the most primitive. The main plus of this technology is low cost. The cost of TN display is 50% lower compared to the cost of other technologies. Such matrices have a number of shortcomings: small viewing angles (no more than 60 degrees. If more, the picture begins to distort), bad color reproduction, low contrast. The logic of manufacturers to refuse this technology is clear - there are a lot of flaws, and they are all serious. Nevertheless, there is one dignity: response time. In TN matrices, the response time is only 1 ms, although the response time is usually 5-8 ms in IPS-screens. But this is just one plus that cannot be placed in contrast to all disadvantages. 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 1 and 5 ms. The photo below the difference is clearly visible. Pay attention to the color distortion at an angle on the TN matrix.

Unlike TN, IPS matrices show high contrast and differ in huge viewing angles (sometimes even maximum). It is this type that is the most common, and sometimes they are referred to as SFT matrices. There are many modifications of these matrices, so when listed the advantages and minuses, you need to keep in mind any particular type. Therefore, below for the listing of advantages, we will keep in mind the most modern and expensive IPS matrix, and for the list of minuses is 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 greater 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 slope of the display (still, the viewing angles are not always maximum on some types).
  3. Outsimation of color and insufficient saturation.

Today, most phones have IPS matrices. Gadgets with TN displays apply except in the corporate sector. If the company wants to save money, then it can order monitors or, for example, phones for their employees cheaper. They may have TN matrices, but no one buys such devices for themselves.

AMOLED and SUPERAMOLED screens

Most often, SAMSUNG smartphones use superamoled matrix. This company belongs this technologyAnd many other developers are trying to buy or borrow it.

The main feature of amoled matrices is the depth of black. If you go around AMOLED display and IPS, then the black color on IPS will seem light compared to Amoled. The very first such matrices had implausible color reproduction and could not boast of color depth. Often the so-called acidity or excessive brightness was present on the screen.

But the developers in Samsung corrected these shortcomings in Superamoled screens. These possess specific advantages:

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

Disadvantages:

  1. Higher cost;
  2. The need for calibration (settings) of the display;
  3. It can rarely be a different period of operation of diodes.

On the very Top flagships AMOLED and SUPERAMOLED matrix are installed due to better quality Pictures. The second place is occupied by IPS screens, although it is often impossible to distinguish the quality of the image AMOLED and IPS matrix. But in this case it is important to compare subtypes, and not technology as a whole. Therefore, you need to be on a check when choosing a phone: often in advertising posters indicate technology, and not a specific subtype of the matrix, and the technology does not play a key role in the outcome quality of the picture on the display. BUT! If the TN + FILM technology is indicated, then in this case it is worth saying "no" such a telephone.

Innovation

OGS Air Blood Removal

Engineers every year represent image improvement technology. Some of them are forgotten and do not apply, and some produce a furor. OGS technology is just such.

The standard screen of the phone consists of a protective glass, directly the matrix itself and the air layer between them. OGS allows you to get rid of the excess layer - the air layer - 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 quality of the display is obvious. For the last couple of years, OGS technology is unofficially considered a standard for any more or less normal phones. Not only dear flagships equipped with OGS screens, but also state employees and even some completely cheap models.

Bending glass screen

The next interesting experiment, which later became innovation - this is 2.5D glass (that is, almost 3D). Thanks to the screen bends, the picture becomes more voluminous. If you remember, the first smartphone Samsung. Galaxy Edge. Produced Furior - is he the first (or not?) Received a display with 2.5d glass, and he looked amazing. On the side even appeared additional touchpad To quickly call some programs.

HTC had an attempt to do something unusual. The company has created a SENSATION smartphone with concave inside the display. Thus, it was protected from scratches, although it was not more beneficial to achieve. Now there are no such screens for the already strong and unresponsive to scratch protective glass Gorilla Glass.

At this HTC did not stop. A smartphone LG G Flex was created, which has not only bent the screen, but also the housing itself. This was the "chip" of the device, which also did not gain popularity.

SAMSUNG stretching or flexible screen

For a middle of 2017, that technology is not yet used in any available phone available in the market. However, Samsung in videos and presentations demonstrates amoled screens that can be stretched and then return to the opposite position.

Photo of a flexible display fromSamsung:

Also, the company presented a demonstration video of the video, where the screen bezed to 12 mm is clearly visible (as the company itself says).

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

The best smartphones with amoled matrices

Given the fact that Superamoled technology was developed by Samsung, mainly it is used in the models of this manufacturer. And in general, Samsung is leading in the field of developing screens to improve mobile phones and televisions. This we already understood.

To date, the best display of all existing smartphones is the Superamoled screen in Samsung S8. This is even confirmed in the DisplayMate report. Who is not aware, Display Mate - a popular resource, analyzing screens "from and to". Many specialists use their test results in their works.

To determine the screen in S8, I had to even enter a new term - Infinity Display.. It received such a name thanks to an unusual elongated form. Unlike previous screens, Infinity Display is seriously modified.

Here is a brief list of advantages:

  1. Brightness up to 1000 NIT. Even in the bright Sun content will be well readable.
  2. Separate chip for the implementation of Always On Display technology. And without that economical battery now consume even less battery charge.
  3. Function to improve the picture. In Infinity Display, the content without a component of HDR acquires it.
  4. Brightness and color settings are automatically adjusted depending on user preferences.
  5. Now there is not one, but two light sensor, which more accurately allows you to automatically adjust the brightness.

Even compared to the Galaxy S7 Edge, which had a "reference" screen display in S8 looks better (on it white colors are truly white, and they go to warm tones on S7 edge).

But besides Galaxy S8 there are other smartphones with screens based on Superamoled technology. It is mostly, of course, the model of the Korean company Samsung. But also there are others:

  1. Meizu Pro 6;
  2. OnePlus 3T;
  3. ASUS Zenfone 3 Zoom Ze553KL - 3rd place in the top of the Asusu phones (located).
  4. Alcatel Idol. 4S 6070K;
  5. Motorola Moto Z Play and others.

But it is worth noting that the hardware part (that is, the display itself), although he plays a key role, but also important to software, as well as minor software technologies that improve the quality of the picture. Superamoled Displays are famous primarily to the opportunity to widely adjust the temperature and color settings, and if there are no such settings, then the meaning to use these matrices slightly disappears.

Recently to the market came out LG G3., first smartphone with Quad HD screen resolution (2560 × 1440 pixels). The newest creation of LG will have to face other flagship smartphones whose screens are also considered exceptionally good in one way or another - Sony Xperia Z2, HTC One. (M8), iPhone 5S And, of course, SAMSUNG GALAXY S5.

We compare the displays of these smartphones on a number of parameters (brightness, readability in the sun, resolution, color reproduction, etc.) and we will try to determine the best of them for the aggregate of estimates.

Brightness and readability in the sun

The first key area on which we focus will be brightness and visibility in the sun. We learn how good the displays of smartphones behave outdoer, where a lot of bright light.

The high level of maximum brightness is of paramount importance for any smartphone. In the end, what a sense from big ScreenIf you can not comfortably use it on the street? IN lately Manufacturers cell phones It was possible to achieve decent results in this area, although we are still far from ideal. Most top android smartphones have a maximum brightness level of about 450 yarns. This is enough to disassemble information on the screen, but not for comfortable work, especially under the right sunlight. The LG G3 and Xperia Z2 screens can reach about 450 threads of maximum brightness, while HTC One M8 indicators are slightly higher than - 490 yarns.

To truth, if you look outdoer, you can hardly notice any difference between the HTC One M8 and Xperia Z2 screens. As for LG G3, it looks a little dull. In addition, the smartphone tends to overheating - it automatically reduces the level of brightness to 90% and does not allow it to return it back to the maximum. None of the other smartphone from our list has such behavior is observed. Galaxy S5, in turn, can easily overshadow all three, provided that the Adapt Display option is activated. The maximum brightness of the GS5 screen varies depending on the displayed content. On average, it is almost the same as the iPhone 5S screen, which in the sun is capable of losing the maximum brightness of up to 580 yarns. Thus, the favorites here are flagships from Apple and Samsung, but before the ideal is still very far away as you can see on the images below.

Another important factorwhich we must consider this minimum brightness. This indicator will be important for those who often use a smartphone at night in bed. It is necessary to significantly reduce the brightness of the display to comfortably use it in complete darkness. Therefore, the lower the value of the minimum display brightness, the better. Some companies well worked in this direction - for example, Samsung assure that Galaxy S5 can reduce brightness to record 2 Nits! Having measured the level of minimum brightness when displaying white, we made sure that GS5 is really the best in this category, although the iPhone 5S, which took second place, was very close with the result of 5 yarns. LG G3 occupies an honorable third place (9 NIT), it is a bit brighter, but also very good. Finally, HTC One (M8) and Sony Xperia Z2 divided the last place with an indicator of 16 minimum brightness yarns. Most likely, in complete darkness you will not want to spend a lot of time before their screens. The final estimates were distributed as follows:

Color reproduction

Color reproduction is a very complex area for research, but it is extremely important, as it defines how beautiful and accurate the image on the screen. It is safe to say that getting accurate color reproduction is the most difficult task for screens manufacturers at present. The size, brightness and screen resolution are no longer a problem. But finding a perfectly calibrated display - a rarity.

Color temperature is one of the most important parameters. It reflects the balance between red and blue and determines which shade has an image on the screen - cold or warm. The color temperature is measured in the degrees of Kelvin, and the reference value is 6500 K. Smartphones, as a rule, slightly close to cold (bluish) tones, and none of the participants in our comparison has become an exception to this rule. Xperia Z2 performed best: the color temperature is 6900 k, which is very good. With a slight lag behind the iPhone 5S and HTC One (M8) with a result of approximately 7150 K, slightly pushing the LG G3 (7300 K). Galaxy S5 is worse than all in this regard. In the standard mode, the color temperature ranges near 8100 K, although you can switch to "Professional Photography" or "Cinema" mode to lower this indicator. But, despite the fact that you can get relatively close to the reference value, the image begins to suffer from another problem - an overaction of green color that spoils a picture strongly. There are no other smartphones from the list of such problems.

Gamma curve (brightness dependence on the shade) is another important indicator that demonstrates how correctly the screen displays various colors. The reference value is 2.2, but some manufacturers deliberately lifting the gamut, as it makes the picture more contrasting. In this category, the iPhone 5S wins with the average gamma value 2.21. Galaxy S5 is completely close (2.25), while Xperia Z2 turned out to be noticeably far from ideal (2.59). LG G3 has a gamut 2.32 - a fairly decent result, although a little more contrast than necessary. Finally, HTC One (M8) is the only gamma below the norm (2.11), this means that certain areas will look a little brighter than necessary.

We also measured the error of the color (Delta E) and a number of other indicators. The measurement results are shown in Table:


Resolution

In the mobile industry, we have long overcome problems such as "pixelity" and other images of images due to low detail. After the iPhone 4 with its revolutionary repetition, the Retina display with pixel density 326 PPI, as well as the HTC Droid DNA (the first smartphone with FullHD display), has recently been taken another plank - the LG G3 screen has a QUAD HD resolution (2560x1440) and pixel density 538 dpi. Thus, we were in a situation where the screen resolution is not only enough, but even excessively. The transition from 720p to 1080p brought a small, but still a noticeable difference in terms of clarity of the image. However, now that LG gives an impetus for QHD (2560x1440) displays, we begin to doubt whether something more than Full HD is really (1920x1080), even for such huge 5.5-inch screens. As we said in our LG G3 review, the differences between QHD and Full HD for the naked human eye are very minor, so if you expect the resolution QHD in LG G3 significantly improves the image quality and makes it seem much clearer and detailed, you Stay disappointed.

The remaining participants of our comparison, with the exception of the iPhone 5S, have full HD screens with a diagonal of about 5 inches. This leads to a pixel density of more than 400 dpi - a very high value that guarantees an extremely clear image. In places, the screens of smartphones in this category are quite difficult, since most of them have about the same level of detail. iPhone 5S with its Retina display also leaves very good impression From viewing, but with a resolution of 1136x640 and pixel density 326 points per inch on it, you can still see individual pixels if you carefully look at. Nevertheless, it is completely not a problem.

Conclusion

LG G3 is wonderful smartphone In many ways, his screen is definitely one of the most remarkable features. A giant 5.5-inch display affects not only the size, but also stunning image clarity, which will undoubtedly attract a lot of attention from technically savvy people and innovation lovers. That is why we spent detailed comparison His display with screens of major competitors.

After carefully studying all the displays, we came to the conclusion that they are all very good, with some small nuances.

If you look at the final estimate (arithmetic average of all estimates), the LG G3 and Galaxy S5 screens are slightly inferior to their opponents. The main problem of LG G3 is a relatively worst visibility in the sun, while Galaxy S5 suffers from the inaccuracies of the color balance. The screens of the other smartphones (iPhone 5S, HTC One M8 and Xperia Z2) cannot be called fundamentally better, just in general they turned out to be slightly more balanced. The iPhone 5S boasts the best color reproduction and brightness, but in the end it turned out to be on a par with HTC One M8 and Xperia Z2, since the latter is a slightly clearer image.

In conclusion, we must make some conclusions regarding the novice in this comparison, LG G3. The company did a very good job and created an excellent base for further developments. However, one permit is not limited to one permission, according to some parameters, the G3 display is far from perfection. Sometimes it is better to be a solid good one than an excellent student in one single discipline.
