PLS matrix type - manufacturing technology, features, pros and cons. IPS vs PLS

The PLS (Plane To Line Switching) matrix is ​​a unique development from Samsung, which is based on IPS technology. As a rule, it is actively used by the South Korean manufacturer in TVs, smartphones and monitors. Its undeniable features include the widest possible viewing angles, high pixel density and high-quality color rendition. Full sRGB coverage and deep blacks are sure to be appreciated by professional photographers, designers, and creative people. This matrix is ​​a worthy competitor to IPS screens, having its own advantages.

Which display is best for gaming?

PPI: dots per inch

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

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

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

If you don't take care of yourself, glasses will soon become a sad necessity.

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

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

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

Difference between IPS and LED screen?

As you now understand, IPS and LED refer to different monitor components and are not mutually exclusive. You can have an LED monitor with or without an IPS display.

As for the main functional difference, it all comes down to what you're hoping to achieve with the monitor. IPS monitors are ideal for graphic designers, photographers, or artists who want color accuracy and a distortion-free widescreen monitor, but aren't too concerned about refresh rates. The idea is to get a realistic representation of colors, and IPS works best, explaining why creatives prefer Apple's Retina Display (its own variant of IPS).

A gamer who relies on crisp frames per minute to play the latest high-octane shooter would probably prefer a TN monitor for faster response times, although IPS provides better overall image quality. TN's better contrast may also be preferable for detecting enemies in shadowed areas or dark buildings to gain a competitive advantage in the game.

When it comes to LED lighting over CCFL, there is absolutely no comparison. CCFL is more or less obsolete and most manufacturers are phasing it out. LED is cheaper, more reliable, lasts longer, and is generally less harmful to the environment than its fluorescent equivalent. In recent years, contrast and color gamut have also caught up with CCFL, so there is very little loss in quality.

Screen coating

Until recently, the screens of mobile devices were covered with ordinary plastic, which quickly scratched, distorted color reproduction, and did not have a very tactile feel. It was replaced by glass, which doesn’t care about keys lying in your pocket. Nowadays there is not a single type of glass on the market that differs in strength and, accordingly, in price. 2.5D glass with curved edges has gained particular popularity today. They not only guarantee high reliability, but also give the smartphone a more stylish look.

In addition, the screens of modern smartphones have a special grease-repellent coating (oleophobic layer), which ensures good finger gliding and also prevents stains. To determine the presence of an oleophobic layer, just place a drop of water on the screen. The better the drop retains its shape (does not spread), the better the quality of the layer.

Naturally, the quality of the oleophobic layer and glass affect the cost of the smartphone. You are unlikely to find a budget model that can boast the same durable glass as the flagship solution. Today, the most popular manufacturer of protective glass is Corning, whose line ends with Gorilla Glass 5.

AMOLED

AMOLED technology is an active matrix based on organic light-emitting diodes. Nowadays we often see it in a new look - Super AMOLED. With these displays, individual pixels light up separately. This is called the active matrix. Moreover, they burn on the top of the thin film transistor (TFT). When the entire array passes through an electrical organic compound, it is called OLED. But some companies are cunning and do not pass through the entire array, leaving an unfinished version of the display, which is called TFT. It is cheaper than AMOLED because it has an incomplete cycle. Or, to put it simply, this is half of the whole process. But in any case, a complete or incomplete cycle of this technology shows a better picture than that of IPS LCD. But not in all regions. Assembly is different. So we can only talk about the picture as a whole.

At the heart of its technology, OLED uses anodes and cathodes to flow electrons through a very thin film. The brightness is determined by the strength of the electron current. And color is controlled by tiny red, green and blue LEDs built into the display. The best way to understand the process is to think of each pixel as an independent light bulb with three colors to choose from.

Colors tend to be brighter on AMOLED and Super AMOLED, and black tones appear darker due to part of the screen that can be effectively turned off. When the light bulb is not lit, it produces a “pure” black color. When all three colors are lit, it produces a “pure” white color. So the contrast is better, the colors look brighter, more saturated. Just because each element works separately. Each pixel in this case is an independent nature.

Moreover, it is not said anywhere that the rich colors of the display must destroy the battery charge faster. Battery performance rather depends on the efficient operation of the processor. So AMOLED may be more power hungry than IPS LCD.

Another thing is that AMOLED burns out faster. And this has nothing to do with sun exposure. It’s just that in this case the display works at full capacity, which leads to more intense wear. So pixel quality degrades over time. But they are actively working to solve this problem.

It is also often noticeable that upon closer inspection of a smartphone or tablet based on this technology, the user seems to see all the pixels separately. Only in this case you need to look at the screen at a distance of less than 5 cm, which, of course, spoils your eyesight. So these experiments have no actual application in life. The average user holds a tablet or smartphone about 30 cm from their face.

Samsung

is a big fan of Super AMOLED displays and actively equips its devices with advanced technologies in this area. This also applies to white balance and sharper black tones. So the latest devices from the Korean manufacturer have amazingly rich pictures and are not afraid of the sun. A wide viewing angle and a long time of normal pixel operation are included.

The key difference between Super AMOLED and standard AMOLED technology (which is often used by companies that are trying to save money, such as Motorola) is that Super AMOLED has reduced the thickness of the protective film over the sensors by an order of magnitude, which results in a more saturated color under the same conditions security.

Plus, Super AMOLED also offers better battery life, although again manufacturers work hard to minimize the differences between the technologies.

Super Amoled matrices

This type of display was developed in 2009 by Samsung. The main and only goal of developing this screen is to use it in mobile phones, smartphones, tablets and other mobile devices with a touch screen. Already in 2010, the Korean company released a new type of matrix called Super Amoled. The difference between Amoled and Super Amoled is the absence of an air gap between the layers of the second type of screen (S-Amoled).

This solution made it possible to make the screen even thinner. Also thanks to this, the brightness of the display increased by 20%. At the same time, energy consumption remained at the same low level. In theory, such features make Super Amoled screens impervious to bright light. In other words, the user sees the image perfectly even in direct sunlight. However, in practice this is not the case. Of course, a comparison of IPS and Super Amoled shows that S-Amoled wins in this parameter, but in any case, with direct rays the picture becomes difficult to distinguish.

2.1. Advantages of Super Amoled matrices

If we talk about touch screens, then first of all it is worth noting that this type of screen is characterized by higher sensitivity and quick response to user gestures. In addition, there are other advantages:

• The highest brightness among all types of screens;
• The largest viewing angles;
• High saturation and maximum number of colors and shades;
• Partial suppression of glare in sunlight, which improves image perception in bright sunlight;
• Low power consumption, which is extremely important for mobile devices;
• The service life of the screen is one of the longest.

Results: which type of matrix in a smartphone is better for the eyes

It is impossible to say which screen is better, since both technologies have their drawbacks, including when comparing the effect on the eyes. AMOLED is less harmful , since it allows you to control the degree of backlight, turn off most pixels, and so on. However, we must not forget about PWM, which can negatively affect vision.

For drawing, modeling, photo processing and other things, it is better to choose devices with an IPS matrix; they are less susceptible to fading and are able to convey color correctly. At the same time, for reading and life in general, it is better to give preference to AMOLED, despite its shortcomings.

Basic principles of technology

Super amoled from Samsung is a technology based on the use of organic light-emitting diodes, which are used as light-emitting parts, thin-film transistors that control them, and are presented in the form of an active matrix.

To produce new screens, two technologies can be used, the difference of which lies in the pixel structure: matrix plus and PenTile. In super amoled plus, the matrix has a traditional subpixel structure (red-blue-green) and an equal number of them.

When implementing PenTile technology, an RGBG scheme is used, which has four colors (red-green-blue-green). The super amoled plus matrix has approximately 50% more subpixels than PenTile, resulting in better image quality and clarity. However, Samsung decided to first use the PenTile matrix, since it is more durable than plus. This is based on the degradation of blue subpixels, of which there are much more in the plus matrix and therefore it fails faster. However, further developments have made it possible to use super amoled plus.

The shortcomings of the selected matrix are compensated by the manufacturer in the form of a larger screen made using super amoled technology.

Advantages and disadvantages

Optimal organization of production and modernization of the technological process through the introduction of developments make it possible to produce HD super amoled screens, the cost of which is much cheaper than their analogues. They are distinguished by high resolution and small thickness, which has almost no effect on the linear dimensions of electronic devices.

A display made using super amoled technology using PenTile or plus matrices is also characterized by the following advantages:

• Reducing energy consumption of electronic devices by 20%

One of the main problems that is inherent in all gadgets and various means of communication is the ineffective consumption of battery power. Super amoled technology extends their operation time, including due to the presence of LEDs, thanks to which the display backlight is not required.

• No distortion in the perception of visual information in bright sun

Now you don’t need to cover the display with your hand or any objects: the new development allows you to read texts and play various games even in direct light, without fear of glare.

• Wide viewing angle

It is 180⁰, but the image does not reduce its clarity and does not become blurry. This allows you to view graphical information without changing the display's tilt and provides excellent image quality.

• Increasing screen brightness

In addition to the clarity of the lines, super amoled technology with both the plus matrix and PenTile allows you to obtain brighter, rich colors and shades, and color rendering has increased by 30%.

• Contrast

When using an HD super amoled screen, there is no “blur” effect during video playback, and clear boundaries between different image formats and in the transition from color to color are visible.

• Reliability and durability

The new displays produced by Samsung do not have air cushions, so mechanical strength and service life are increased.

The disadvantages of HD super amoled include the predominance of cold shades when transmitting images and the short service life of LEDs. On large displays of this type they fade no later than 2-3 years after the start of use, and on mobile communication devices - after 5-10 years. But since during this time the means of communication become obsolete, this lifespan of HD super amoled is considered acceptable.

Application area

Most often, the creators of new developments seek to implement them to improve the characteristics of their own products. So Samsung in February 2011 launched the production of electronic devices with a newly developed screen, which turned out to be the Samsung Galaxy S II series smartphones. It was through their example that consumers felt all the benefits of new technologies.

Development prospects

A special feature of the process of creating HD super amoled displays is the ability to complement their device without changing all stages of production, but only modify it, adding layers with new characteristics. The latest improvement consists of the following layers:

• Touch film
• A protective covering to which low voltage wiring is attached. It is transparent and glued to the previous one
• Layer with LEDs responsible for the image
• Thin Film Transistors
• A backing layer that can be made from a variety of materials

It is on improving the last layer that all the efforts of the developers are directed: these developments make it possible to create flexible displays from Samsung with the planned characteristics. In turn, flexible screens will help radically change the way mobile electronic devices operate.

In constant competition and race between manufacturers, new technologies are born every year that surpass their predecessors in all respects. This also applies to manufacturing technologies for modern displays. Just imagine, some 15-20 years ago we only knew CRT picture tube screens. They were bulky, heavy and had a low flicker frequency, which negatively affected our health. But today, users can choose between Amoled or IPS, as well as other types of matrices that allow them to make screens as flat and light as possible.

In addition, modern types of matrices are distinguished by the highest image accuracy, high resolution and quality. In this article we will talk specifically about two modern technologies - Amoled (S-Amoled) and IPS. This knowledge will help you make the right choice to suit your requirements. But in order to understand which display is better in a particular situation, it is necessary to analyze both technologies separately.

Color saturation

Compared to other matrices on the market, IPS has a number of clear advantages. Unlike the TN-TFT technology previously used in TVs and monitors, IPS have the ability to transmit more saturated colors in the RGB gamut with 8-bit channels. The TN matrix commonly used in LCD monitors actually outputs 6 bits per channel, which does not provide enough depth to the image. IPS TVs provide deeper blacks and stronger whites.

These displays are ideal for watching videos and working with photos.

IPS LCD

In the other corner of the ring we have an IPS LCD, which stands for In-Plane Switching Liquid Crystal Display. If Super AMOLED is an upgrade from AMOLED, then IPS LCD is an improvement on the first types of liquid crystal displays. The mighty Apple has become fixated on these types of displays, releasing all iPhones with the same technology over the years. It's cheaper to produce, which is a bonus. But iPhones have never been cheap. So?

Essentially, LCD uses polarized light, which is then passed through a color filter. No separate elements. Horizontal and vertical filters on either side of the liquid crystals control brightness and operate regardless of whether each pixel is on or off. We add backlighting here and we see that usually phones with similar technology have a rather thick body. iPhones from Apple

this is rather an exception.

Since all the pixels are backlit, the black balance turns out backlit, “gray”. This is where the contrast suffers. But the white color doesn’t care - it loves many colors, so white looks more beautiful than all other tones on this technology and sometimes even better than an oleophobic display, since there it becomes a little yellowish. The most interesting thing is that Apple calls one of its colors offered for phones dark gray. It's black though. Just overexposed. Because it cannot be otherwise. But against the background of the same color of the case it is not so noticeable. Mimicry tricks the eyes. We think we see black because the brain matches it with the color of the body. A cunning commercial move.

The first thing that's bad about this technology is that the viewing angles are often not very good. This is again the fault of the backlight. Photographers tend to choose IPS LCDs because they display colors more accurately. After all, photographs are often taken in excellent artificial or natural lighting, hence the predominance of white over black. And when we see black and gray night photos, we can blame the bad flash. Only the flash has nothing to do with it. This is the same “dark gray” black color.

Expert opinions

On some sites you can find information about an independent study of PLS ​​and IPS.

Experts compared these technologies under a microscope. It is written that in the end they did not find any differences.

Other experts write that it is still better to buy PLS, but do not really explain why.

Among all the statements of experts, there are several main points that can be observed in almost all opinions.

These points are as follows:

• Monitors with PLS matrices are the most expensive on the market. The cheapest option is TN, but such monitors are inferior in all respects to both IPS and PLS. So, most experts agree that this is very justified, because the picture is better displayed on PLS;
• Monitors with a PLS matrix are best suited for performing all kinds of design and engineering tasks. This technique will also cope perfectly with the work of professional photographers. Again, from this we can conclude that PLS does a better job of rendering colors and providing sufficient image clarity;
• According to experts, PLS monitors are virtually free from problems such as glare and flicker. They came to this conclusion during testing;
• Ophthalmologists say that PLS will be much better perceived by the eyes. Moreover, your eyes will find it much easier to look at PLS all day than IPS.

In general, from all this we again draw the same conclusion that we already made earlier. PLS is a little better than IPS. And this opinion is confirmed by most experts.

Additional screen

If one display is not enough for you, then a number of companies offer smartphones with additional screens. They are usually small and serve to display notifications. And YotaPhone 2, known to many, offers a second E-link display that occupies the entire back side, which is convenient to read. LG's lineup includes solutions with a small screen that displays notifications. Meizu recently launched a similar smartphone with an additional screen with its flagship Pro 7.

The second screen is a rather unique feature that not everyone needs. Nevertheless, such smartphones find their user, and more than one.

What is an LED monitor?

LED, on the other hand, refers to a type of backlight used to illuminate the liquid crystals on an LCD monitor. LED stands for light-emitting diode and in the context of LCD monitors is distinguished from other lighting standards by cold cathode fluorescent backlighting, or CCFL.

There are two types of LED arrangements. Edge-lit LEDs that sit on the edge of the screen, distributing light evenly across the screen, and guide the entire LED array, where the LEDs are located directly behind the screen.

The benefits of TFT LED monitors include lower power consumption compared to CCFL displays, as well as improved quality when it comes to display brightness, and the contrast ratio is higher, producing better true blacks as well as a wider color gamut than CCFL. Likewise, the sum monitor can be extremely thin and light when using LED backlighting with improved reliability compared to CCFL.

The presence of LED displays further complicates the situation. An nLED display uses LEDs instead of liquid crystals as the core screen or monitor technology. LED displays were popular in the 1970s but fell out of favor as monochrome displays, and when full color displays were introduced in the late 1980s, LCD technology entered the market. However, in the last decade they have resumed thanks to Sony OLED technology and Crystal LED Integrated Structure. They remain significantly more expensive than LED-backlit LCDs.

Comparison of IPS and PLS matrices

If you display an identical image on two different IPS and PLS screens, you can immediately see, albeit small, but still existing differences. The PLS matrix benefits not only due to increased brightness, but also more vibrant colors. The image on this screen is very rich and beautiful. PLS screens are almost completely free of harmful flicker that tires the eyes. Moreover, such a matrix has less impact on the user’s vision. This is evidenced by tests and analyzes by leading ophthalmologists.

As for viewing angles, there is practically no difference between PLS and IPS. Both matrices demonstrate excellent performance, so you can admire the image from any angle. The response speed of these displays is the same. It all depends on the specific manufacturer and model. Typically, the response time is between 5 and 10 ms. This is a good indicator, but still inferior to TN.

It is worth noting that the quality of the picture largely depends not only on the matrix itself, but also on other parameters of the monitor or TV. An important role is played by the backlight, the processor, the presence of additional functions and other aspects. But we can certainly state that IPS matrices consume more electricity than their competitor PLS. The difference may not be so significant, but it is still present.

To summarize our comparison, the PLS matrix wins in many respects. The gap from IPS is not so great as to speak of an unconditional victory for the younger technology. And in some moments there is parity, because both technologies are very similar in structure. But the palm still lies in the hands of PLS ​​screens produced by the legendary South Korean brand.

Features pls:

• Accurate and high-quality color rendition
• Increased brightness
• No unnecessary flicker
• Low energy consumption

IPS Features:

• High sensitivity
• Relatively low cost
• A universal solution for any task

Which matrix to choose: PLS, IPS, VA or still TN?

The issue of choosing a new monitor or TV is always acute, because such equipment is purchased for more than one year. Of course, a lot will depend on personal preferences and individual needs. At the same time, it should immediately be noted that of the three different matrix options there is no ideal choice. All displays have weaknesses that cannot be avoided. If you do not experience any special financial problems, then it is recommended to choose PLS technology, as it is the most balanced.

Do you want to install a TV in a compact room, and also prefer to save your personal budget? Then VA matrices, which stand out for their most correct display of black, would be a good choice. VA displays have no competitors in terms of contrast levels.

You shouldn’t write off IPS matrices, which have long been in high demand among the population. Moreover, their cost is constantly decreasing, which makes IPS screens in demand among the population. Their strongest points are traditionally very wide viewing angles without harsh color conversion, lack of glare (if the monitor is matte) and decent color rendition. But the high sensitivity made it possible to use them in smartphones and tablets. The user just needs to touch the touch screen to perform some action. IPS touch displays will be especially appreciated by artists and designers who use advanced technologies to achieve the best results.

avid gamers to opt for TN monitors, because only they can provide a truly low response. In this case, you will not observe trails and blurring of the picture in especially dynamic moments of the game.

professional photographers, videographers and designers pay attention to PLS matrices, because they stand out from competitors with more accurate colors, increased brightness and pixel density. The image here looks very juicy and beautiful. PLS will be the best solution in terms of vision safety, as it does not create unnecessary strain on the eyes.

As we have already noted, each matrix has its own characteristics and some shortcomings. Therefore, you must initially understand the purpose of buying a TV or monitor. Once the objectives are defined, making the right choice will not be difficult. And our article will make your life even easier, so as not to doubt the advisability of the purchase.

Conclusion

It’s difficult to say clearly which screen is better. It all depends on your needs, budget and preferences. The IPS display is suitable for those who love natural color reproduction and are looking for a budget, durable phone. OLED screens provide brighter colors and better picture quality, high contrast and the fastest possible response. The quality of phone screens also depends on the company that uses these technologies in production and the price segment to which the smartphone belongs.

In the SKAY.UA online store you will find phones and TVs for every taste and budget. We have the most honest prices and good delivery conditions throughout Ukraine. Our consultants will answer all questions and help you choose the right product.

Design features of smartphone screens

But you should not only consider the type of matrix when choosing a smartphone screen. There are a whole bunch of other features that affect the final picture quality and user experience. We will focus on the most important points.

Air gap

Until recently, the screens of all smartphones were represented by two components: the touch layer and the matrix itself. There was an air gap between them, the thickness of which depended directly on the manufacturer. Naturally, the thinner the layer, the better. Companies regularly reduced the air layer, making the picture quality higher and viewing angles wider. Relatively recently, it was possible to completely get rid of the air gap thanks to OGS technology. Now the sensor layer and matrix are connected together. Despite the significant improvement in quality, there is an obvious drawback. If the OGG screen is damaged, it will have to be completely replaced, while in displays with an air layer, only the glass takes the hit.

Be that as it may, more and more manufacturers are choosing OGS screens. And we advise you to give preference to this technology. Believe me, there is no need to worry about complex repairs for the feelings that you will experience when using such a display.

Curved screens

A relatively recent thread that Samsung brought to the market with its flagship Galaxy S6 Edge (there was also a Galaxy Note, but only one edge was bent). The South Korean manufacturer will continue to develop the idea in subsequent smartphones, but other companies did not share the idea too much. The company bends the right and left edges of the devices - the screen seems to float onto the ends. This is done not only for the sake of a spectacular appearance, but also for the convenience of the user. Additional functions are placed here, and notifications can also be displayed here. A fascinating feature, but not for everyone.

LG even went further, bending not only the screen, but the entire smartphone in the G Flex model. It looks stylish and interesting, but it didn’t catch on, so the company abandoned this design.

Samsung was the most successful in implementing a curved display, so if you are interested in such a design, we recommend considering the solutions of the South Korean brand.

Frameless smartphones

An even more recent trend is screens without frames. The progenitor is the Sharp company, which showed the first frameless smartphone back in 2014, but users were attracted by the frameless Xiaomi Mi Mix, shown in 2016. By the summer of 2022, a number of companies have announced plans to release similar gadgets. Today, the market is rapidly filling with bezel-less smartphones, with the newest models costing less than $100. To date, there are several variations of the frameless screen: elongated displays, which have reduced frames at the top and bottom; familiar displays without frames on three sides (except for the bottom). The first type includes the Samsung Galaxy S8 and a couple of smartphones from LG (G6 and ). The second includes Bluboo S1, Doogee Mix, Xiaomi Mi Mix and many others, whose ranks are constantly replenished.

Frameless smartphones look really cool, and their low cost gives everyone the opportunity to try out modern technology.

Pressure force

The well-known company Apple introduced a new technology at the time of release in the iPhone 6S - 3D Touch. With it, the screen began to respond not only to touches, but also to the force of pressing. Technology began to be used, as a rule, to perform some quick actions. Also, 3D Touch made it possible to work with text, draw with greater comfort (the brush reacts to the force of pressure) and so on. The function did not become something completely unusual, but it found its user. Later, a similar technology appeared in Meizu Pro 6, and was also announced in ZUK Edge.

Type of touch screens

Not a particularly important criterion when choosing a smartphone screen, but, nevertheless, let’s dwell on it a little. There are several types of touch screens: matrix (very, very rare), resistive and capacitive. Until recently, resistive screens were widespread everywhere, but today they are presented only in very rare and cheap smartphones. This type is different in that it responds to any touch: with a finger, a pen, or even control another phone. It only supports one touch and does not always work accurately. In general, an outdated type.

Capacitive screens are significantly superior to their predecessors. They already support more than one simultaneous touch, have better sensitivity, and work much more accurately. However, their production is more expensive.

Whatever one may say, the vast majority of companies have abandoned resistive screens in smartphones. And this is for the better. In addition, the cost of capacitive ones is constantly decreasing, which allows manufacturers to install them in the cheapest smartphones.

Number of simultaneous touches

Another important aspect when choosing a smartphone screen is the number of simultaneous touches. This parameter determines what operations you can perform on the display. The first smartphones equipped with resistive screens were limited to one simultaneous touch, which was not always enough. The screens of modern smartphones often support 2, 3, 5 or 10 simultaneous touches. What gives a large number of simultaneous touches:

• Scaling and zooming. One of the first features that appeared on the iPhone, the first smartphone to support two simultaneous touches. So, you can reduce or enlarge images by pinching or spreading your fingers on the screen.
• Gesture control. Multiple fingers make it possible to use different gestures.
• Game controls. Most modern games require the use of several fingers at the same time.

You shouldn't chase support for 10 simultaneous touches if you don't play on a smartphone. For the vast majority of users, 5 touches are enough, and even less demanding users will not experience discomfort with 2.
