What is an inch in a phone? Smartphone screen sizes: which one is better to choose and with what parameters? Resolution and DPI

The screen is an integral element of the design of a modern mobile phone. Long gone are the days when the “color” characteristic reflected all the advantages of the model and served as proof that the handset belonged to the upper segment and had flagship characteristics. Today, the variety of mobile phone screens makes it possible to satisfy even the most demanding customers. Downside medal is the abundance of technologies and terms for their designation, among which it is sometimes very difficult for a non-professional to navigate. This article will help you understand all of them, introducing you to the main types of screens, their design and properties.

When characterizing the properties of an input/output device, which is touchscreen, the following parameters are taken into account:

  1. Screen dimensions, its diagonal (most often measured in inches, 1 inch is 2.5 cm).
  2. Resolution (number active points, forming the picture).
  3. Pixel density indicator (expressed in DPI (dots per inch) or PPI (pixel per inch) - the number of dots per inch).
  4. Production technology (image quality and consumer properties of the product depend on it).
  5. Type of touchscreen design (touch covering that responds to touches).

It is these indicators that serve as criteria for choosing a phone. And now more details.

Most screen diagonal modern smartphones is within 4-6 inches ( smaller sizes traditionally installed on simple dialers, and tablet PCs start at the 6" mark).

Resolution and DPI

Screen resolution is one of the most important characteristics of a phone. It depends on it how high quality the picture on the phone screen will be. The higher it is, the greater the pixel density, and the more uniform the image will look. The combination of large dimensions and low resolution makes the picture “grainy” and fragmented. High separation ability, on the contrary, ensures uniformity and smoothness of shapes for the information on the screen. Modern Full-HD screens consist of elements that are indistinguishable to the naked eye, and make the image ultra-clear.

Term Retina display coined by Apple to refer to screens with a pixel density greater than 300 units per inch (for phones). In such devices, the human eye cannot distinguish individual elements of the screen and perceives the entire picture, like the real outlines of an object or its image on paper and canvas. Today, companies such as Samsung, Sharp and LG are engaged in the production of Retina display.

The most common display resolutions today are:

  1. 320x480 pixels - almost out of use, but still found in budget smartphones. It produces an overly grainy picture, which is why it is not popular. Denoted by the term HVGA.
  2. 480x800 and 480x854 (WVGA) are common resolutions among inexpensive phones. Looks normal with a diagonal of 3.5-4", on larger ones it gives an overly fragmented image.
  3. 540x960 (qHD) is a popular indicator for mid-budget smartphones. Provides acceptable image quality on screens up to 4.5-4.8 inches diagonal.
  4. 720x1280 – this is where HD smartphones start. Provides excellent picture detail up to 5.5", looks good on large displays.
  5. 1080x1920 – Full-HD matrices providing excellent image quality. Used in flagship models smartphones.
  6. Separately, it is worth highlighting the displays used in products Apple. They use non-standard resolutions: 640x960 at 3.5" ( iPhone model 4/4s), 640x1136 for 4" (5/5c/5s), and 750x1334 for 4.7" (iPhone 6).

When choosing a new smartphone, you should consider the display size and DPI. Buying a phone with a lower pixel density than its predecessor will take a long time to get used to, and at first it will cause discomfort to the eyes. If the dots per inch density is less than 200, it is possible that you will never be able to get used to it. Pay attention to this when purchasing a phone with a larger diagonal than old pipe: for example, a resolution of 480x800 gives about 233 DPI with a diagonal of 4", and with a 5" diagonal - only 186.

Production technologies, types of smartphone displays

Today we can distinguish two main directions in screen production technologies: liquid crystal matrices (LCD) and organic light-emitting diode (OLED) devices.

The first ones have become somewhat more widespread and are divided, in turn, into:

TN matrices are the most common displays for phones with touch screen. Their advantages are low cost, high speed response (pixel response time to voltage supply). The disadvantages of such matrices include insufficient color reproduction and a mediocre viewing angle.

IPS– the next step in the evolution of display devices. Due to its high cost, the technology was initially used only in professional monitors, but later came to the world of phones and smartphones. Allows you to achieve excellent color rendition, good viewing angles (up to 178 degrees), high definition and contrast. Such screens are more expensive, so they are almost never used in phones costing up to $200.

PLS– an attempt by Samsung to create a solution that does not have the disadvantages of TN matrices, but is cheaper than IPS. In essence, it is a modification of IPS using compromise solutions to reduce production costs.

Organic displays (OLED, AMOLED) differ from LCDs in that instead of liquid crystals, the matrix consists of microscopic LEDs. Such screens make it possible to do without additional backlighting (LCD matrices traditionally use diodes installed around the perimeter of the screen, and the light from them is directed to the matrix using a layer of reflectors). Their energy consumption depends on the color transmitted image(dark shades are more economical than light shades, which display energy consumption even higher than LCD).

Top super amoled
Bottom ips

Theoretically, such displays are superior to LCD in almost all respects, but in practice, it is not always possible to achieve an ideal picture. The disadvantages of the products include low reliability. Super AMOLED display– an attempt to develop a screen specifically for touchscreen smartphones. In it, the touchscreen is one with the display surface. By reducing the thickness, greater brightness is achieved, better color rendition and viewing angles, but the mechanical strength of the product is reduced.

Types of touch screens

The most common are two types of displays:

  1. Resistive.
  2. Capacitive.

Resist ones consist of two layers, on the surface of which transparent conductor tracks are applied. The coordinates of the press are calculated by changing the current resistance at the point of contact. Nowadays such screens are almost never used, their scope of use is limited budget models. Dignity resistive touchscreens are low cost and the ability to press with any object. Disadvantages - low durability, scratch resistance, loss of screen brightness.

Smartphone screen with capacitive sensor- is different greater brightness, scratch-resistant (due to the use of glass), but more difficult to manufacture and does not react to touching foreign objects. The technology is based on calculating the coordinates of current leaks when pressed with a finger. Such touchscreens consist of one layer of glass, on the inner surface of which a conductive layer is applied, or glass and a touch film.

IN Lately capacitive screens are equipped with special tempered glass, like Gorilla Glass, which makes it possible to achieve high resistance to mechanical damage. To prevent contamination, a special oleophobic coating is applied to the touchscreens of smartphones.

Good day, friends. Today, I will tell you how to find out the monitor diagonal in several accessible and understandable ways for everyone. On the one hand, this seems like a trivial question, but on the other, I personally have heard more than once from my acquaintances and friends about a request to determine the diagonal of a computer or laptop monitor. Therefore, I decided in this article to tell you everything in more detail so that you no longer have such questions.

Important nuance!

The diagonal size of the monitor is measured only in inches, remember this.

The very first way to determine the diagonal will be incredibly simple. And it consists of examining the documentation that came with your monitor. Examine it carefully, and I can give you an almost 100% guarantee that in addition to the model of the monitor itself, its diagonal will also be indicated.

If you bought the monitor used, or simply threw away the documentation for it, then skip this step and move on to the second point. Method number 2. Inspect the surface of your monitor most carefully, and especially its corners and the inscription in the middle of the bottom bar; often the manufacturer marks their products and indicates the diagonal immediately after

letter designation as 2-digits. If there are no inscriptions on the front panel of the monitor or they are worn out, then carefully inspect

back

, there is almost always an information sticker there.

Method number 4.

In my opinion, the most reliable and time-tested method. If you do not have documentation for the monitor, there are no stickers or signs on the device itself, and Yandex.Market does not search for your model, the only 100% option for determining the diagonal of the monitor is to measure it using a regular ruler or tape measure.

Take a ruler in your hands (a tape measure is more convenient) and from the lower left corner of the monitor, measure the distance to the upper right corner (you can do it the other way around). Divide the result in centimeters by 2.54.

1 inch = 2.54 cm.

Important! Measurements only need to be taken of the monitor screen itself (without the bezel).

A ruler from the lower left corner to the upper right will show in centimeters, if you need inches, then simply divide the centimeters by 2.54, since 1 inch = 2.54 cm.

For example, I got it like this:

Diagonal in centimeters = 58

In inches - 58/2.54 = 22.83, that is, mine is 23 inches.

That's all friends. You already know for sure how to find out the diagonal of your monitor, so share the information with other users, you need to help everyone.

That's all, until new interesting meetings. The diagonal of the TV plays a big role when choosing a TV receiver. The comfort of watching video on the screen depends on the correct choice of screen size. And it is completely false to say that the larger the TV diagonal in cm

, all the better. How much is it if you convert 1 inch to cm? As is known 1 inch equals 2.54 centimeters

. Inch (from Dutch duim - thumb) is the name for the unit of measurement of distance in European non-metric systems of measures. Today, an inch is most often understood as an English inch, equal to exactly 2.54 cm.

  • It was in 1958 that they decided to accept the value of an inch as exactly 25.4 mm, and before that there were many more digits after the decimal point. The ratio of inches and centimeters is as follows:
  • 1 inch = 2.54 cm = 25.4 mm
  • 1 cm = 0.3937 inch
1 m = 39.37 inches

In the English system of measures, 1 inch = 12 lines = 72 points = 1/12 foot = 1/36 yard. After acceptance international system SI units of measurement, inches are considered an obsolete designation that should be gradually phased out. But, despite this, inches continue to be used in technology when indicating calibers and form factors, for compatibility with long-established technical solutions

In television technology, the diagonal of the screen is expressed in inches, which is measured as the distance between the opposite corners of the matrix. For example, 37" means a screen with a diagonal of 37 inches or 37 x 2.54 = 93.98 cm.

A simple length converter to convert inches to centimeters and cm to inches:

For example, if you take a 32-inch TV, how much is it in cm? Using the calculations in the converter, we find that 32 inches in centimeters will be 81.3. Another example, converting 22 inches to cm, we get 55.9 centimeters. And if we take a diagonal of 42 inches, we get 106.7 centimeters.

TV diagonal in cm and inches, conversion table:

Inches Centimeters
22" 60 cm
32" 82 cm
37" 94 cm
40" 102 cm
42" 107 cm
50" 127 cm
60" 152 cm
70" 178 cm

How to choose a diagonal size

The choice of TV diagonal is influenced by two factors:

  1. the distance from which you will look television receiver;
  2. picture resolution, played on the screen.

And this picture resolution depends both on the screen of the device you purchased, and on the video signal supplied to the TV input.


In the picture you see how to measure the diagonal of a TV.


The higher the image resolution, that is large quantity points are used to form it, the closer you can view the picture on the screen without compromising quality. And the lower the picture resolution, the smaller the TV diagonal in cm should be, or you need to increase the TV viewing distance.

You can check this yourself when choosing a TV receiver. If you look closely at the picture with low quality, For example, terrestrial television, then you can notice all the shortcomings of both the image and video signal processing circuits. And if you step back a little, minor errors will become invisible.

For example, if we take a television receiver with a diagonal of 32 inches, then for a signal with 625 lines (terrestrial television) the distance to the screen will be approximately three diagonals 32x3=96 inches or 96x2.54=243 centimeters, which is approximately equal to 2.5 meters. And if the image resolution corresponds to 720p, then the distance to the screen for normal viewing will be already 1.9 meters or more. If the TV is already Full-HD, then it will be convenient to view the video image from a distance of 1.3 meters or more. These turned out to be the minimum distances to the screen, when viewed from which distortions caused by the structure of the video signal will not be visible in the picture.

For example, if your viewing distance is approximately 2.2 meters, then when buying an HD Ready TV, you can choose a device with a diagonal of up to 37 inches. If you choose a Full-HD TV, you can increase the diagonal to 52 inches without compromising picture quality. And new models with 4K resolution (Ultra HD), which have a video conversion module to UHD resolution, will already be more than 60 inches at this viewing distance.

For example, one of these TVs: Samsung UE-65NU7400.

Diagonal 65 inches, 4K resolution, there is an upscaling module that increases the resolution of any video to 4K.



UE-65NU7400

But when viewing from a distance that exceeds the calculated distance, a big difference between TVs with different resolutions will not be visible. Do not forget that the resolution of the device itself must match the video signal for the highest quality playback. Therefore, when today almost all Full HD TVs and even models with Ultra resolution HD (4 times more than Full HD), then you need to take into account the number of pixels in the video signal.

Terrestrial television currently has SD resolution (625 lines). But it is already spreading more and more digital television, and there the resolution needs to be found out additionally, but it will be greater than SD. There are many films with Full HD quality, but there is still very little Ultra HD content. We can advise you to carry out all calculations today on the condition that you are viewing a video with Full HD quality, and you will receive a minimum viewing distance. And if you need to increase the distance, for example, installing a TV in the living room, then you will not see any damage to the picture quality.

An example of a modern (2018) TV with Full HD resolution: LG 43LK5900.



43LK5900

TV diagonal in cm table

The minimum TV viewing distance and screen diagonal size can be linked by the following table:


The diagonals of TVs are presented in inches and centimeters; the table allows you to choose the third according to two parameters. In the table, select the screen diagonal size horizontally, select the video resolution on the screen vertically (depending on both the TV and the input signal), and at the intersection of these values ​​there will be the required viewing distance in meters.

Programs can produce a signal with 720p quality satellite television, games from consoles, copies of BD discs, digital TV.

1080p resolution corresponds to Full-HD TVs and it is better to use such devices if you have sources of such a signal. Although there is circuit solutions increasing the signal resolution to 1080p, but such schemes do not always work perfectly. Everything needs to be checked on site.

Therefore, it is better to determine the distance to the screen in advance and choose accordingly required resolution and TV diagonal in cm for comfortable viewing.

One of the most important parameters for users that characterizes any screen, be it a mobile phone or a computer monitor, is its diagonal. And since the screen, in most cases, is a rectangle, the diagonal is the line that connects its opposite corners and, in relation to screens, is measured in inches. Sometimes there are non-standard shapes, for example, a circle or an oval. Then the diagonal is taken to be the line passing between the most distant opposite points.

* Inch is a unit of measurement of length. Most often it means American system measures and, translated into the usual metric system, equals 2.54 centimeters. Indicated by the icon “.

The most common are the following standard values:

— Monitors – 17”, 19”, 21”, 23”.

— TVs – 32”, 43”, 49”, 50”, 55”, 65”.

Cell phones and smartphones – 4”, 4.5”, 5”, 5.5”.

— Laptops – 13.3”, 15.6”, 17”, 19”.

* Some manufacturers can be cunning by indicating one of the above numbers on a huge label, and in small print they enter an amendment, most often downward. For example, 19 inches in practice quite easily turn into 18.5” or even 18.3”. This is done by the manufacturer consciously, in order to save money and reduce the cost of producing the device.

Therefore, it is quite obvious that every user asks a question like: “How to find out the diagonal of a laptop monitor?” And not the one that is written on the box, but with which you actually have to work.

Methods for measuring monitor diagonal

Manual diagonal measurement

Manual measurement. Easier and more reliable than the method It’s impossible to come up with - you’ll need a calculator and a ruler. Or a tape measure, a meter, a caliper (it’s a joke about the caliper, although you can also use it). We apply the tape measure to the corners of the screen and remember or write down the resulting value. You need to measure exactly the area where the information is displayed and not take into account the frames around the display.
The resulting numbers need to be divided using a calculator by 2.54 and you will get the required inches. Some length measuring instruments are marked not only in millimeters and centimeters, but also in inches - then there is no need to divide.

Specialized programs

Specialized programs. AIDA64, SiSoft Sandra and similar diagnostic tools will help you find out the diagonal of your computer monitor without resorting to rulers. By going to the “Display” section (the name may differ for various software– we are looking for the most appropriate item in the program menu) where opposite the “Monitor” line there will be the desired parameter.
The program takes the value from its own database, so if the data is displayed incorrectly or is not there at all, we recommend using a newer version.

How to find out the monitor diagonal size using documentation?

If you still have the box from your device, then inspect it from all sides - usually in one of the corners there is a sign with a list where the manufacturer writes down the parameters.

Google to the rescue

Not necessarily, of course, Google, but using a search engine you can get to the equipment manufacturer’s website, where in the section of products manufactured by the company, select your model and see what’s what.

Factory sticker on the case

If the above methods are not suitable for some reason, you can try to inspect the device and look for a factory sticker on the case - the factory will have written down the basic data on it that you can use.

Method of mathematical solutions

For really desperate geometry lovers, we suggest using a method for solving a simple problem. Here the well-known ancient Greek philosopher and mathematician Pythagoras comes to the rescue with his famous theorem. It states that the sum of the squares of the legs of a triangle is equal to the square of its hypotenuse. In our case, the sides will be the vertical and horizontal of the display, and the hypothesis will be the value we are interested in. We perform simple calculations - we square the width and height separately, sum them up and extract from the resulting number Square root. If the ruler is graduated in millimeters, then divide the result by 2.54 and get inches.

*When applying rulers, tape measures, etc. to the display, be careful not to damage the matrix and its coating with sharp parts. Some screens are very fragile, and leaving a scratch is easy.

The first method is the most accurate and guarantees absolute accuracy of the result. You will take the measurement yourself and, with a careful approach to the matter, error will be eliminated.

Diagonal diagonal is different

When choosing an electronic friend based on display size, before finding out what diagonal the monitor has, you should pay attention to the aspect ratio. The total screen area with an aspect ratio of 4:3 is larger than that of 16:9. The first option is more suitable for typing documents, browsing the Internet, office work With text files. The second format has a multimedia focus - wide-format cinema, graphic editor, watching videos, video processing programs. Therefore, if you do not plan to work on a computer, then 16:9 will be optimal choice– films will not be cut off at the edges with black stripes.

Other measurement methods

We hope that the methods we have proposed will be enough to find out the monitor diagonal in any situation, and we will not consider completely exotic ones. Let’s just list them for, so to speak, general educational purposes:

  • Laser rangefinder.
  • Use an object of known length.
  • Odometer. This is a device for measuring length and distance, it is a wheel that needs to be rolled along a segment and the arrow of the device will show the distance traveled in millimeters.

The choice of smartphone is influenced by many factors. One of them is the diagonal of the smartphone. Perhaps this is perhaps the most important factor. After all, it determines how easy the smartphone will be to use. Therefore, we decided to tell you about this parameter in detail.

How do you measure the diagonal of a smartphone?

If you haven’t lived your whole life in a village, then the essence of the diagonal should be clear to you. In fact, the diagonal shows the distance measured from one corner of the screen to the opposite. IN technical specifications this parameter is indicated in inches - this has been the custom since the days of “pot-bellied” TVs.

It should be noted that different smartphones with the same screen diagonal they can have different heights and widths. The fact is that the size of the device is influenced by two other factors:

  • Side frames - if they turn out to be narrow, then the width of the gadget will be relatively small. And narrow or completely absent side frames make control operating system and applications more convenient.
  • Aspect ratio - the width of the device also depends on it. Tablets most often use a display with an aspect ratio of 5:4. On smartphones, the most popular settings are 16:9 and 18:9. In the second case, the device turns out to be narrow and ideal for simultaneously displaying two applications.

If you look at old smartphones, you will notice that they have a small screen (3.5 inches was the most popular diagonal), but huge bezels around it. Now technology has reached the point where the side frames can be quite narrow. And in the future, many smartphones will not have them at all (similar models still exist, but their number is very small). In short, from now on engineers have the opportunity to build fairly large LCD panels into relatively compact gadgets. This makes smartphones more versatile. They become more convenient for watching movies and spending free time playing games.

What does the diagonal affect?

A lot depends on the diagonal of the smartphone display. First, it affects the way you use the device. Secondly, power consumption and stability of operation depend on the size of the screen. In short, let's figure it out.

Let's start with user experience. If you buy (a smartphone whose display diagonal exceeds 5.5 inches), you risk encountering certain problems. Such a gadget may not fit into a shirt pocket or the back pocket of jeans. You will also have to regularly use your second hand - practice shows that the user does not have a chance to reach upper corners thumb. But on a device with a large display, movies look great! Just don’t forget to make sure that the screen of the smartphone you purchase has a high resolution! However, we will talk about this separately. More on large display It's easier to type text when working with documents. That is why phablets from the series have always been popular among office workers.

It is difficult to say anything specific about devices with a small or medium display. By at least, regarding user experience. Some will say that it is impossible to read books or watch movies on a 4.7-inch LCD panel. But in fact this is completely untrue. To be honest, to watch videos it is better to use a 10-inch screen or even a TV. More compact devices will in any case be less convenient for these purposes. By the way, the author of this article as a child calmly read several books on the Siemens CX70 with its tiny TFT display. And on a 2.2-inch screen Nokia smartphone E65 was watching the sixth season of the series “Lost.” In short, if the content is interesting, then a small screen will not cause any inconvenience.

We stock up on energy for big and juicy pictures

Well, what can we say about the influence of the LCD display on the performance of the smartphone? Perhaps you have already guessed that a large diagonal consumes significant amounts of energy. At least this applies to IPS panels and screens made using similar technology. They have separate layer backlight that evenly illuminates the entire display area. And if this area is larger, then the battery charge is consumed more actively. That's why larger smartphones often come with larger batteries. If the screen is made according to AMOLED technology, then everything is not so bad - the differences between different diagonals will be less noticeable (but they still do not disappear).

Large resources are spent to display images on a larger screen. That is, if two smartphones with different displays will have the same processor, then a larger device will work slower. Although this is not true in in every sense this word - still, the biggest impact on performance is resolution, not diagonal.

Which screen diagonal is more popular: 4,5,6,7?

Recently, large companies have almost completely stopped producing smartphones with a display diagonal of less than 5 inches. Only Apple continues to produce compact devices. And their owners will tell you that it is smartphones with relatively small screen are the most convenient to use. Unfortunately, device lovers Android based They stopped taking the diagonal from 4.3 to 4.7 inches seriously. Therefore, manufacturers decided to concentrate their efforts on larger devices.

Numerous surveys show that people like devices with screen sizes ranging from 5.0 to 5.3 inches. If the side frames are narrow or absent altogether, then a 5.5-inch or even 5.7-inch diagonal is quite acceptable. These are the parameters that the vast majority of smartphones currently selling have.

Devices with a screen whose diagonal exceeds 5.7 inches are already so-called phablets. They are close to the performance of tablets, but they are not very convenient to use. Such smartphones are also popularly called “shovels.” Despite the fact that using them for raking sand and snow is also inconvenient, their size is clearly insufficient for this.

What should the display resolution be?

Long gone are the days when we were content with a resolution of 240 x 320 pixels. Now the screen sizes have increased, and therefore the resolution should be higher. Why? Everything is very simple. If we watch TV from afar, then the smartphone is usually a meter from our face or even closer. The resulting low resolution causes us to see individual pixels. You will like this least of all when reading text. And the low resolution will not allow you to appreciate any film or video.

If the screen diagonal is 4.7 inches or slightly larger than this parameter, then HD resolution (1280 x 720 pixels) will be enough for you. Such a display will also not load the processor much, so you will be able to run many modern games even with a weak chipset.

If the display diagonal is at least 5 inches, then Full HD resolution (1920 x 1080 pixels) will be ideal. In this case, individual pixels can only be seen under a magnifying glass. It should also be remembered that many films are now distributed in this resolution. But do not forget that such a screen has high power consumption.

5.5 inches – minimum Full HD

Finally, when reaching 5.5 inches, it may not seem traditional. Therefore screens flagship smartphones Now they get 2K or even 4K resolution! Such devices are ideal for use in conjunction with a helmet. virtual reality. Even under huge lenses, individual pixels will only be visible after you long time peer into what is happening on the screen. Such smartphones must have a camera with high resolution, otherwise the photos will look lacking in detail. The device must also have capacious battery, because so a high resolution will consume huge amounts of energy. However, modern processors They are fighting this factor more and more, which is good news.

It should be remembered that the changed aspect ratio affects the screen resolution. If for 16:9 the usual values ​​are 720 x 1280 and 1080 x 1920 pixels, then in the case of atypical aspect ratios the manufacturer adds 100-200 pixels to the height. In this regard, games will put an increased load on the processor, because it will have to process additional pixels. This is worth remembering when you choose a smartphone with a narrow screen.

What else should you pay attention to?

Any screen portable device has a certain diagonal and resolution. Now you've got it. Now the aspect ratio may also differ, which you already know. Well, what other parameters do LCD displays have?

The first thing that comes to mind is the technology of creation. The cheapest smartphones may have a TFT screen. This will be your worst choice! The display created using this technology has very limited viewing angles. If you tilt the device slightly, the colors will be distorted or even inverted. This will significantly reduce the comfort of watching movies or, especially, games. Also, such LCD panels behave disgustingly on the street.

Rest assured, every photography process will become terribly inconvenient for you. Fortunately, now even budget devices are increasingly equipped with an IPS display. Viewing angles in this case depend on specific production methods. But even the cheapest panels distort the picture when the device is tilted, then only barely. Many buyers do not notice such distortions at all, despite the fact that they are still present! And if the screen is expensive, then you won’t see any problems with the picture at all. At the same time, the colors will be as natural as possible. Such LCD panels are built into

AMOLED screens perform best in terms of energy consumption. This is due to the fact that such a display does not have a separate backlit layer. Each of its pixels glows independently. It's easy to guess that a large number of Black colors on the screen will result in lower power consumption. Also, such screens have extended color range(although the most expensive IPS matrices are almost as good). Because of this, some people find the picture on the AMOLED display too bright and saturated. However, most often there is no problem with this. For example, on Samsung smartphones you can choose a specific one color profile, excluding saturation - in this case, in terms of picture quality, the screen will be similar to any IPS panel.

The viewing angles of AMOLED screens are maximum. And if the display belongs to one of last generations, then there is a high chance of finding the “Screen always on” option in the smartphone settings. When turned on, the device will be in constant mode display the date, time and some other information. Most of the screen will remain black, so this feature has virtually no effect on power consumption.

When choosing a smartphone, you may wonder how bright the backlight is. However, often this parameter is not indicated in the technical specifications. Therefore, it is better to read reviews of the selected device. They will definitely contain photographs of how the device behaves on the street. But about protective glass is usually indicated in the specifications. However, its manufacturer is not always written. Be that as it may, if the glass was created by Corning, then at least focus on the third generation Gorilla Glass. Glasses apart from each other different generations differ in thickness and strength. The newer the glass, the thinner it is, and it can also withstand a fall from a greater height.

Summarizing

Now you know almost everything about the screens of modern smartphones. We talked in detail about what the display diagonal affects, and whether increasing it is always a plus. Moreover, we have mentioned resolution and some other parameters. Most likely, from now on you will not have problems choosing a smartphone and evaluating its screen.
