What type of screen is best for a laptop
3 popular types of matrices: IPS, PLS and TN. which monitor is better
A good monitor is the pleasure of movies, web surfing, work and gameplay. To find one, you need to look not only at the classic parameters such as size and resolution, but also at what type of matrix is installed. This article explains what types of LCD monitors and matrices are.
How LCD panels differ from each other, what are their advantages, as well as what disadvantages they have. All this will help you understand which panel is better to choose a display for specific tasks.
This type of matrix is used in budget devices, as well as in gaming displays. There are practically no TNs left in their pure form today, but manufacturers often tend to ignore “Film” when describing characteristics, since it has already become a standard for modern models. Such panels are not without drawbacks, but TNFilm also has attractive features.
Tip: If you are looking for a super fast monitor, the KG271 is the right solution. The matrix of this widescreen display responds in 1 millisecond.
As a result, we can say that this version of the screen is almost the best for the gamer, as well as for undemanding movie lovers and users working with documents. But a monitor with such a matrix is hardly suitable for designers.

Disclosure of concepts
Before moving on to the concepts of matrices, it is worth talking about the notation of the displays themselves. The descriptions include options such as LCD, LCD and TFT screens. What is their difference?
LCD is a generic designation for the category of screens that TFT belongs to, however, the designation TFT LCD on the box often causes confusion. It’s actually quite SIMple.
LCD is a flat panel display based on liquid crystals: this is what is called LCD in its purest form. TFT is an LCD-based panel. But in the manufacture of such a panel, transistors are used, which are of the thin-film type. And this is its only difference from other LCD versions.
Interesting: Many manufacturers make displays curved. The C27F591F is just that. And it also has decent speakers with a total power of 10 watts, so it is not necessary to connect acoustics to it.
What are the types of LCD matrices
There are only four main types of panels on the basis of which monitors of computers and laptops are made:
- TN is almost the oldest development;
- IPS is perfection itself;
- PLS. not inferior to its predecessor;
- VA is a good development that web designers and photographers have already appreciated.
All others are just variants of the above. Below. about common modifications.
TN and TN Film are the easiest options. The full name is Twisted Nematic. Versions supplemented by “Film” are a variation. It differs from its ancestor by an additional layer. As you might guess from the name, the models in this category have been improved for a more comfortable movie viewing.
IPS (In-Plane Switching) matrices were created by HITACHI. The goal of the creators is to develop something better than the aforementioned panels.
In such matrices, crystals, when an electric field is applied, rotate together, rather than create a spiral. It is due to this that the creators succeeded in a 178-degree viewing angle from all sides. At the moment, such an indicator is the maximum possible.
MVA and VA. were created as an alternative to expensive IPS. We have developed such a panel in Fujitsu offices. These options have become more affordable, while the color rendering, response speed and viewing angles are very attractive.
In the case of VA, when creating an electric field, the crystals are aligned horizontally, and the layers of the panel do not let the backlight light through. MVA has subpixels divided into several zones. In modern multi-domain models, one cell can contain 4 zones. Each filter has a ledge on the inside, all elements are zoned so that the crystal orientation in each zone is most suitable for viewing the panel from a certain angle. over, crystals move independently in different zones. The result is decent viewing angles without color distortion.
WVA (Wide Viewing Angle) is another modification of VA technology, which has a solid view, just like IPS. up to 178 degrees. However, according to other characteristics, WVA is still inferior to her. However, these differences are so insignificant that it is not always easy even for professionals to notice them.
PLS-matrix (Plane to Line Switching) is an alternative version of IPS models, which was presented by Samsung. Classical IPS is superior in pixel density (image quality is not lost), in a wide range of shades. An ordinary user may not notice such differences, but professional designers have already appreciated PLS.
PVA (Patterned Vertical Alignment) is one of the variations of TFT MVA, from Samsung, the only difference of which is the deep black color.
But which matrix is still better? The answer depends on why. For games. one option, but for design and cinema it may be completely different. Below is a description of the most common.

Here the crystals are distributed evenly across the entire screen, parallel to each other. Thanks to this solution, these matrices are distinguished by the ability to convey natural shades and a gorgeous view from different angles. IPS screens have many advantages, and devices with panels in this category are very popular. They are almost universal as they are great for gaming, watching movies, and many professional tasks. In addition, recently, IPS monitors are not as expensive as they used to be.
What are the advantages of an IPS display:
- When viewing photos or working with graphic images, matrices of this category pleasantly surprise with color reproduction. Even the black color will not differ in any way from the original. It will not become overly saturated or greyish. When processing a photo / video, you do not have to worry that the final result will differ from the author’s idea when demonstrating. This makes the matrix much better than the TN panel.
- Sun exposure will not degrade image quality. Yes, there are glare if the screen is not matte, but the sun will not cause color distortion.
- The picture quality remains high and is not distorted no matter from which corner of the room you follow what is happening on the screen. Sharpness and contrast are maintained. Reminder: the view from any angle for such LCD monitors is maximum. 178 °.
- If we are talking about devices with a touch screen, then IPS will delight you with high sensitivity. Controlling a display with such a panel is the pinnacle of comfort: you can work with both drawings and pictures. The screen responds vividly to both the finger and the stylus. Artists, designers, architects will definitely appreciate this feature.
- IPS costs significantly higher compared to TFT.
- Not as responsive as TN models, although the Predator XZ271A with IPS panel boasts millisecond response. However, there are still few such monitors.
- Devices with IPS screens consume more power.
As mentioned above, this is a Samsung development, which was created to give the user a worthy replacement for IPS. And the company succeeded. PLS. not to say that it is much better than IPS, but such monitors have SIMilar characteristics in terms of quality and capabilities.
The first product was released back in 2010. It was not possible to reduce the price of such devices, and, in fact, an ordinary PC user did not find significant differences from the popular IPS. But professional designers still found the difference and successfully use such monitors as a “workhorse”. You shouldn’t wait for something fundamentally new when watching movies and or playing games.
Four best features of PLS-based LCD monitors:
- Glare and flickering are practically absent, and therefore, when working for many hours behind such a monitor, eyes get tired less.
- Improved color reproduction and hue accuracy make the display nearly ideal for designers and planners.
- Average response time. 4 milliseconds.
- Average brightness indicators. 1100 cd / m2, which is 100 units higher than IPS.
Interesting: the PLS-based S24E391HL has a cool feature that smooths textures at low image resolutions, so even a poor quality movie can be watched with such a monitor.
Each of the matrices has its own advantages, but not without its disadvantages. So on the basis of which panel is it better to choose a monitor? Gamers, and especially fans of shooters and racing, as well as all kinds of games of a different genre that require quick reactions, definitely need the option with the fastest possible response. Such high-speed monitors are made with TN matrices. Even in action games, shots that quickly replace each other do not leave a nasty trail. For design, it’s better to take something with a nicer image. It could be MVA or PLS. Undecided and all inclusive supporters will love the IPS monitor. He will delight both with the breadth of the soul (that is, the overview) and with natural flowers.
If we are not talking about budget models, when one of the purchase criteria is maximum savings, then talking about a screen resolution lower than FullHD, in our times, is somehow undignified. Indeed, the recently familiar 1366 x 768 screen looks like an anachronism.
Here 1920х1080 is our size. Or even more. By the way, at the same time I will also give a plate with the accepted designations of those permissions that can now be found.
|HD||1366 x 768|
|HD||1600 x 900|
|QHD / WQHD (2K)||2560 x 1440|
|QHD (3K)||3200 x 1800|
|UHD (4K)||3840 x 2160|
Should you chase screen resolutions higher than 1920 x 1080? I’m not sure if the image on a 15-inch 4K screen is significantly different from FullHD, but the price. yes, much more. And do not forget about higher power consumption (for those who often work away from the outlet, this may be relevant). Well, in gaming models, in order to reveal all the splendor of the graphic solution of this or that game in this resolution, you will need the remarkable power of the hardware used by the laptop.
So, for a 15-inch screen, the optimal (and minimum) resolution is FullHD. Do you need more? If you have the means, and you know for sure that you need just such a screen, 2K or even 4K. In some Dell XPS 15 hundreds for one and a half thousand rubles, the screen is smaller than UHD, it seems to be out of order.
Response time is a sacred monitor parameter for any gamer. Everyone knows that the lower the value, the better. And first of all, this is provided by screens made using TN technology. A value of 1-2 ms is not a problem for them. This is one of the main reasons, besides being cheap, why such matrices are still popular. For the sake of the absence of loops behind fast-moving image elements, one can forgive the disadvantages of color rendition, low contrast, etc. IPS screens are not so fast, but they are increasingly found in gaming models.
6 tips for choosing a laptop screen. Expert recommendations
What do we think about when choosing a laptop first? About the processor, RAM, availability of SSD, installed video card. What kind of screen is used in a particular model usually does not come first. But it is he who will have to look at all the time you use the computer, the convenience of work depends on him and how quickly your eyes get tired. How to choose a laptop screen, what characteristics are important, what to look for today and talk.
Unlike stationary computers, laptop owners are not spoiled for a variety of sizes of installed displays. The most popular are 15 and 17-inch. There are fewer, especially in 2-in-1 devices, sometimes there are more. And yet it is from these two values that the laptop model is selected.
Here you have to find a compromise between mobility, convenience and the final cost. Naturally, you want a bigger screen, but the purchase budget is not endless. It is clear that for all equal characteristics, a screen with a larger diagonal will be more expensive.
Therefore, the dimension of the display, and, therefore, the entire laptop, depends on the tasks for which the purchased device is intended, and the final price.
In most cases, you will have to choose from two types of matrices. TNfilm (in common use. TN) and IPS. The first one is fast, cheap, but with poor color rendering and small viewing angles. over, the quality of matrices can vary within fairly large limits. Images on different laptop models with seemingly SIMilar TN displays can vary significantly.
The latter, IPS, have excellent viewing angles, good color rendering, but they are more expensive and their response time is higher, which cannot but upset gamers. But this is not so scary for those who are engaged in image editing. For them, more important is color accuracy, color gamut.
Speaking of color gamut. Traditionally, the color space visible to the eye is represented in the form of a chromatic diagram based on a reference color model proposed in 1931 by the International Commission on Illumination (CIE). The color gamut of a reproducing device (these are not only screens of monitors, smartphones, etc., but also color printers) is a contour superimposed on this diagram.
This parameter is not always present in the specifications for the device, which is a pity. It allows you to evaluate the capabilities of the matrix used and understand how it is suitable for work, or, perhaps, this laptop model with such a display can be immediately excluded from the purchase options.
Screen performance is assessed using a color gamut representation standard, most commonly sRGB. The display matrix performance is reflected as a percentage of the sRGB spectrum coverage. The closer it is to 100%, the better the color display. Adobe RGB or NTSC, which are slightly wider than sRGB, can also be used.
The same laptop model, but with different modifications, which use different display matrices, may have different characteristics. So, the MSI GE72 7RE APACHE PRO model in the version with a 4K screen has 100% Adobe RGB coverage, and in the version with a FullHD 120 Hz screen, the Adobe RGB coverage is 83%, and sRGB is 100%.
IPS-screens have a wider color gamut “by definition”. Therefore, if you have to deal with image processing, preparation of printing materials, etc., then there is only one option. a monitor with just such a matrix.
On sale you can find notebook models with IGZO matrix developed by Sharp. They are distinguished by high image quality at high resolutions, while having a high response speed. In addition, the power consumption is less than that of IPS.
There are models with OLED technology screens. Such matrices are thinner, have better color rendering, black color is really black, without flare, high response speed, but, like IGZO, it is still more expensive than IPS, and they are rare.
Here you need to understand exactly whether you really need a touch screen. If we are talking about a laptop-transformer, then there are no options, a touchscreen is needed. If “classic” is chosen, then are you ready to pay more for such a screen compared to the usual one, do you agree that such a screen consumes more electricity (and, therefore, the autonomy will be worse), are you ready to put up with a glossy coating and. respectively, with a rather strong mirror effect.
Personally, I don’t really like glare screens, although the picture quality is usually higher than on matte ones. If you have to work in bright light, you often take your laptop on trips to sit with it outdoors, under the sun, a glossy screen is not the best solution.
The typical refresh rate of modern monitors is 60 HZ, and there are also models with a frequency of 75 HZ. This parameter shows how many times per second the image on the screen can be refreshed. In powerful gaming notebook models, you can find matrices operating at 120 Hz. Typically, such screens have computers with top-end video cards that are capable of delivering a large number of FPS with high resolution in almost any games.
One unpleasant property associated with the refresh rate is the horizontal tearing of the image. In short, the essence of the problem is as follows. The frame rate is fixed by the monitor, for example, at 60 HZ, each frame is displayed every 16.7 ms. At the same time, the video card prepares each next frame for a different time, which can be less than the refresh rate, and maybe more if the complexity of the scene is high.
If the rendering time is less than the refresh rate, there are no problems, but with a larger value, an unpleasant effect occurs. Typically, a video card uses two frame buffers, the image from which is displayed on the monitor. While the image is being displayed from one buffer, a new frame is created in the second. When the image from the first buffer is displayed on the screen, the next time the screen is refreshed, it switches to the second buffer, and the next frame begins to form in the first.
The problem is that the monitor can switch to a different buffer at a time when the image formation in it is not finished yet. As a result. a picture “torn” horizontally on the monitor.
The V-Sync vertical synchronization mode partially solves the problem, when the monitor does not update the image from the buffer in which the formation of the next frame has not finished, skipping the next iteration of the update cycle. And everything would be fine, the problem seems to be solved with gaps, but another nuisance arises. “friezes”, they are “lags”, they are also delays, violation of the smoothness of the image.
As a rule, the lesser of these two evils is chosen. tears, which is not very pleasant, but at least the image on the screen does not freeze or twitch. Monitors with a refresh rate of 120 Hz can somewhat reduce this unpleasant effect, but they do not completely solve the problem.
Is there a solution at all? Yes, and calls this technology G-Sync, proposed and implemented by NVidia. By the way, AMD has a SIMilar solution, called FreeSync. SIMilar in end result, but implemented in a slightly different way. However, this is a topic for another conversation.
So, the point of G-Sync is to dynamically update the screen. The frame is rendered as it prepares, as soon as the video card has finished rendering it. The screen refresh is waiting for this process to complete. As a result, the problem of image tearing goes away, and with delays, everything becomes well too. For example, the GT72S 6QE DOMINATOR PRO G laptop has a modification with a FullHD IPS screen with support for G-Sync technology.
So, for players, the presence of G-Sync is a boon that they will surely appreciate. If this technology is not in the model, then screens with a refresh rate of 120 Hz can partially get rid of image artifacts.
How to choose a laptop screen?
So which option to choose, which screen will be the best choice? I think I will not be mistaken, or I will be mistaken, but not much, if I say that the best solution is an IPS matrix with a resolution of at least FullHD, matte, without a touchscreen. However, each monitor has other characteristics, which can be found in other material.
G-Sync support is desirable for gaming laptops. Or, as an option, a screen with a refresh rate of 120 Hz. Whether it is necessary to strive for resolution more than FullHD is a question for discussion. For 15-inch laptops, I don’t see a big need for overpayment for such an opportunity. For screens 17 inches or more, maybe. But you will have to pay at least several thousand rubles for this. True, given the cost of such models, this is an insignificant increase in price.
And I strongly advise you to “touch” the selected model “live”, especially if you plan to purchase a model with a TN matrix. It is advisable to check how comfortable the screen is, whether you are satisfied with the limitations in viewing angles, how high-quality the color rendition, whether the screen brightness is sufficient, especially if the laptop will be used often in bright light.
Happy and correct shopping!
Methods for determining the type of matrix
The first and easiest option is to find the necessary information in the documentation for the laptop, if it has been preserved. Everything about the main parameters of the screen will be indicated there: resolution, display diagonal, type of backlight, and other features. To replace, you must select a matrix of the appropriate type and size.
However, if the device has been used for a long time, it is often not possible to determine the type of laptop matrix from documents. In this case, you can use one of several additional methods:
- Download and install on your computer the Everest program, another name for this application. AIDA64. You can download it from the link below.
Run the program and go to the “Display” tab. You will see the heading “Monitor Name”, and below it will be the manufacturer of the matrix and its model. Usually this information is already enough to find the parts you need. The same application will help to correctly determine the size of the laptop matrix, the information will contain the maximum visible area, aspect ratio and maximum resolution.
How to find out what type of matrix is on a laptop?
To carry out repairs or purchase new components, you need to know which matrix is installed in the laptop, and which models are suitable for replacement. The easiest way to find out. disassemble the device, disconnect the matrix and read the marking on it. However, disassembling a laptop yourself is not an easy and dangerous task, so it is better to use one of several other methods. How to find out which matrix is in a laptop?
The main types of laptop matrices
To figure out which matrix is on a laptop, it is important to be able to read the manufacturer’s markings. It is not always necessary to change the matrix to an original part of the same manufacturer, most often you can choose a compatible analogue with the same dimensions and technical parameters.
The most common modern matrix types are designated by the following abbreviations:
- TNFilm is the most common option; these are the matrices that are installed on budget notebooks. They differ in small viewing angles, and if dead pixels appear on the screen, they look like bright dots.
- MVA matrices have a wide viewing angle and improved color reproduction, as well as increased image contrast. A characteristic feature. a broken pixel looks like a black dot.
- IPS matrices. They have a viewing angle of 180 degrees, while the image is practically not distorted. Dead pixels look like black dots, a working matrix has a high image contrast.
In all cases, the best answer to the question of how to determine the model of the laptop matrix is to contact the service center. This is one of the most expensive parts, so when choosing, you must first understand all the parameters.
But what about 16 to 9? What is the best screen resolution for a 19 “monitor? A widescreen monitor has a slightly different structure. Therefore, the resolution will be different. However, most manufacturers advise using Full HD (1920 x 1080 pixels) resolution on 19 “widescreens. It is it that is most comfortable for work. over, if the user sits at the computer for days, then at this resolution the load on the eyes will be minimal. This is important, as the wrong resolution can seriously damage the user’s eyes. Now let’s move on to more voluminous toys. Next in line are the giants with a screen diagonal of 22 inches.
These devices are still marketed as home screens. However, putting them on the desktop is already a little problematic. But some people do it. What is the best screen resolution for a 23 ”monitor? But it is better to look at the accompanying documentation of the device, because these displays can support both Full HD and 2K, and 4K. The optimal resolution for a screen of this size would be 2K resolution. If your device is designed for it, then feel free to expose. But with 4K, it’s better to slow down for now. Such permission. is still a fairly new “feature”. Therefore, not all operating systems and programs are yet adapted to it. But the work is in progress. Do not forget that in order to set this resolution, you need a special driver from the monitor manufacturer. It can be downloaded from the official website or installed from the disc that comes with the device.
Please be aware that monitors 23 ”and above are more hazardous to the eyes if the resolution is not set correctly. Which screen resolution is best for your monitor is up to you. But following the manufacturer’s recommendations will be useful. The specifications indicate exactly those resolutions that were tested under various operating modes. It is at these numbers that the monitor showed the best results. Therefore, you should not neglect the advice of the engineers of the manufacturing company. Sometimes they contain very useful information. In the meantime, we are moving on to an even larger diagonal. 24 inch.
If the maximum resolution is not set
This is a common problem for those who have just sat down at the computer. If in the operating system settings it is impossible to set a resolution of more than 600 x 800 pixels, then this means that there are not enough drivers in the system. And it’s not at all a fact that drivers are needed specifically for the monitor. It is much more likely that a novice user SIMply forgot to install the software for the video card. Then such tricks are possible. If the drivers for it cost 100%, then it makes sense to check their version. It also happens that the “firewood” of the old version does not want to define new monitors. Therefore, it is highly desirable to update the video card software to the current version.
Well, with that diagonal, thank Gates, there are only LCD panels. Here we will talk about them. What is the best screen resolution for a 22 ”monitor? It’s not all that SIMple here. Devices with such a diagonal have both IPS and TN matrices. But this is not the main thing. And the main thing is that there are models with both the declared Full HD-resolution and 2K. And if your monitor has a 2K resolution, then it is not a fact that it will be comfortable for work. Here you will have to select a resolution “by eye”. Play around with the settings, move the sliders. Try on different options. There are cases when the image in Full HD looked better on such a monitor than the “native” 2K. However, you should not get carried away too much. No need to lower the screen resolution “below the plinth”. The image won’t get any better.
You can also read the accompanying documentation for the device. Maybe there will be recommendations on what resolution is best for the monitor. But it is not a fact that they will match your preferences. Generally the screen resolution. rather abstract value. Each user customizes the computer for himself, including the monitor. One thing is certain: this component must be configured in such a way that the user is as comfortable as possible to work with it. Because it is through the monitor that tons of information are transmitted. And if you sit for a long time at an incorrectly configured display, then you can go blind. And you need it?
Okay, now on to the really big toys. Next in line are monitors with a diagonal of 23 inches.
What determines the choice of resolution?
It depends on many factors. When choosing the optimal resolution, you should take into account the screen diagonal, aspect ratio, matrix type and monitor “hertz”. Although the latter parameter was applicable to CRT displays. Modern LCD panels do not require fine tuning of “hertz”. However, other characteristics affect the screen resolution for the monitor. Which is better? We will understand this through trial and error. He alone is effective in this case. Also, do not forget that the screen resolution directly depends on the capabilities of the operating system. For example, Windows OS is very poor at scaling text and icons to 4K resolution. While in Linux OS (“Ubuntu”, “Mint”) there are no such problems.
If the monitor shows nothing at all
There are several options here. First, you haven’t plugged it in. Check power and connecting cord. Second: you need special drivers for this monitor. The latter problem often occurs with G-Sync enabled devices. You just need to install the software from the CD that came with the monitor. Option three: if you have a CRT monitor, then you have set an unacceptably high “hertz”. Wait a minute and the image will return.
These devices are not very different from the previous ones. And therefore, their work permit is SIMilar. So what’s the best screen resolution for a 24-inch monitor? Answer: exactly what it is designed for. Everything here is exactly the same as in the previous model. But because of the non-standard aspect ratio, you will have to adjust the resolution manually, “by eye”. In 24-inch monitors, the aspect ratio is 16 to 10. That is why you have to select a resolution that is comfortable for the eyes. By the way, 24-inch monitors are not as frequent guests on users’ tables as their 23-inch counterparts. Apparently, users are quite conservative and do not want to suffer with a non-standard aspect ratio. However, the market share of these monitors is still very high. The next monitor we look at will be a real giant. 30-inch screen.
It is extremely rare to see such monsters on user desktops. Unless professionals in some field will buy such a display. Or a crazy gamer. The average user will never buy anything like this. In a standard apartment there will be no place to install this monitor. It’s easier to connect your computer to your TV. The effect will be the same. But there are such boxes, and we have to put up with it. So what is the best screen resolution for a 30-inch monitor? Again, it all depends on the manufacturer’s specifications. But if you look purely at the diagonal, then you can safely set 4K. If the monitor supports this resolution. It makes no sense to put less. Icons and text will look pathetic at lower resolutions.
Some “thirty” are also sharpened for 2K-resolution. It’s okay too. But in no case try to put Full HD. Nothing good will come of it. What screen resolution is better for a monitor, in this case, manufacturers know better. Therefore, it is worth following their recommendations. However, thirty-inch models should only be used by professionals. In this case, the more, the better. This is especially true for designers and those who work with images. There is not much text, but the image display quality will noticeably increase at high resolution.
What is the best screen resolution for a monitor? What are the most important parameters?
The modern market for computer peripherals and components is ready to offer the consumer a great variety of monitor models. All of them can differ in the type of matrix, display diagonal, type of backlight or aspect ratio. Also, different monitors may have different screen resolutions. Modern models are able to easily hold even 4K resolution. But is it right for your monitor? This is a big question. As a rule, manufacturers indicate only the maximum value that the device’s display is capable of. They tactfully omit the optimal figure. So what is the best screen resolution for a monitor? This will be discussed in the material.
If we talk about which is better in operation: IPS or TFT, then it is worth noting that the former are more power-consuming. This is because it takes a lot of energy to rotate the crystals. That is why, if the manufacturer is faced with the task of making his device energy efficient, it usually uses a TN-TFT matrix.
If you choose a TFT or IPS screen, then it is worth noting the wider viewing angles of the second, namely 178 degrees in both planes, which is very convenient for the user. Other types of matrices have proven unable to provide this. And one more significant difference between these two technologies is the cost of products based on them. TFT matrices are currently the cheapest solution that is used in most budget models, and IPS belongs to a higher level, but it is not top-end either.
To determine what will be better or worse in each case, it is required to find out what functions and tasks each type of matrix is responsible for. In fact, IPS is a TFT, or rather its kind, in the manufacture of which a certain technology was used. TN-TFT. These technologies should be considered in more detail.
Which screen type should you choose: IPS or TFT? IPS or TFT display is better?
Modern devices are equipped with screens of various configurations. The main ones at the moment are displays based on liquid crystals, but different technologies can be used for them, in particular, we are talking about TFT and IPS, which differ in a number of parameters, although they are descendants of the same invention.
Now there are a huge number of terms that denote certain technologies hidden under abbreviations. For example, many may have heard or read about IPS or TFT, but few understand what the real difference between them is. This is due to the lack of information in the electronics catalogs. That is why it is worth understanding these concepts, as well as deciding whether TFT or IPS. what’s better?
TFT (TN) is one of the methods for producing arrays of liquid crystal screens, that is, screens on thin-film transistors in which the elements are arranged in a spiral between a pair of plates. In the absence of voltage supply, they will be rotated towards each other at right angles in the horizontal plane. The maximum voltage forces the crystals to rotate so that the light passing through them leads to the formation of black pixels, and in the absence of voltage. white pixels.
If we consider IPS or TFT, then the difference between the first and the second is that the matrix is made on the basis described earlier, but the crystals in it are not arranged spirally, but parallel to the single plane of the screen and to each other. Unlike TFT, the crystals in this case do not rotate in the absence of voltage.
How we see it?
If you look at an IPS or TFT screen, the visual difference between them is in contrast, which is provided by an almost perfect reproduction of black. On the first screen, the image will appear sharper. But the quality of color rendering in the case of using a TN-TFT matrix cannot be called good. In this case, each pixel has its own hue, different from the others. Because of this, colors are highly distorted. However, such a matrix also has an advantage: it is characterized by the highest response speed among all existing at the moment. The IPS screen requires a certain amount of time in which all parallel crystals will complete a full reversal. However, the human eye barely picks up the difference in response time.
IPS or TFT display to choose?
The first technology allows you to get the highest quality, sharpest image, but it takes more time to rotate the crystals used. This affects the response time and other parameters, in particular the rate of battery discharge. The color rendering level of TN-matrices is much lower, but their response time is minimal. The crystals are arranged in a spiral here.
In fact, one can easily note an incredible chasm in the quality of screens powered by these two technologies. This also applies to cost. TN technology remains on the market solely because of the price, but it is not able to provide a juicy and bright picture.
IPS is a very successful continuation of the development of TFT displays. High contrast levels and fairly wide viewing angles are additional advantages of this technology. For example, with TN monitors, sometimes the black color itself changes its shade. However, the high energy consumption of IPS-based devices is forcing many manufacturers to resort to using alternative technologies or to lower this figure. Most often, matrices of this type are found in wired monitors that do not operate on a battery, which allows the device not to be so volatile. However, there are ongoing developments in this area.
The characteristics of laptop screens are few, so even an inexperienced user can independently choose a laptop, having figured out which screen in the device he needs.
Before buying a laptop, you need to ask yourself the following questions. What should be the diagonal of the laptop? What should be the aspect ratio and resolution? What technology and screen surface is needed?
The diagonal of the screen determines the size of the laptop, and the choice of this component should be approached especially carefully. The options “the more the better” or “the less the better” will not work here. Initially, you should decide what range of tasks the device will solve. For developers and users who actively use graphic tools and multimedia capabilities of the device, it is worth taking a closer look at “large” laptops with a screen diagonal of 17.3 inches. For non-resource-intensive tasks, netbooks (laptops with a small diagonal) are ideal. The diagonal of the screen is considered to be 15.6 inches. such devices are the most widespread.
It is also worth considering such a factor as mobility. Laptops are called portable computers for a reason. they are convenient to use whenever and wherever you need it. However, if you are an active person, travel often or just move a lot, you should pay attention to small netbooks, the weight of which you will not even notice in your backpack, and their battery life will pleasantly surprise you. In extreme cases, you can consider devices with a diagonal of 15.6 inches. Anything more is convenient only for replacing a desktop PC, since laptops with a diagonal of 17.1 ”and above have a screen that is familiar to many users.
Screen resolution refers to the number of horizontal and vertical dots displayed on the screen. For example 1600×1200. The most popular ones today are: 1366×768 (aspect ratio is equivalent to 16: 9), 1280×1024 (5: 4), 1280×800 (16:10), 1024×768 (4: 3). As you can see, aspect ratio and screen resolution characteristics are interrelated, and the choice here depends on personal preference.
The technology for manufacturing matrixes of liquid crystal displays today knows four main types: TNfilm (often SIMply indicated as TN), IPS (SFT), PLS and MVA. We will not go into the details of the manufacturing process and the principle of operation, we will pay attention only to the differences, advantages and disadvantages.
TN film (Twisted Nematic film) is the SIMplest technology. Has the shortest response time, as well as low cost. The payoff for this is the worst color rendering and the smallest viewing angles.
IPS (In-Plane Switching) or SFT (Super Fine TFT) are two names for one technology. In comparison with TNFilm, they have a slightly increased viewing angle, as well as high contrast and color reproduction. Disadvantage. long response time.
PLS (Plane-to-Line Switching) is an alternative to the previous technology developed by Samsung. Advantages: high brightness, good color rendering, large viewing angles, low power consumption. Disadvantages: Long response time and low contrast.
MVA (Multi-domain Vertical Alignment). represents a compromise between TN and IPS (SFT, PLS).
Glossy or matte?
You can often hear the question: which screen to choose: matte or glossy? Or how a matte screen differs from a glossy one?
The matte surfaces of the screens exclude the appearance of glare, but the image on such a screen turns out to be less bright and saturated. Glossy screens are better at transmitting brightness and contrast, but do not have anti-glare properties. It is believed that matte screens are ideal for work laptops, and glossy screens for multimedia.
What type of screen is best for a laptop
What is the most important part about a laptop? Well, of course it’s his display. And all modern laptops are equipped with LCD displays that use liquid crystals. This miracle of technology was discovered back in 1888. Then it was found that these crystals have the same properties as liquids. However, unlike liquids, crystals retain a clear molecular structure.
And first, their properties were used in the manufacture of displays for electronic clocks. Well, today they are used for the manufacture of laptop matrices. Since then, among professionals, there has been a debate about which type of matrix is better for a laptop? Let’s try to understand this issue.
MVA (types. ASV, PVA), in the absence of voltage, liquid crystals become in a perpendicular position relative to the second filter. When voltage is applied, they make a turn at a right angle, preventing a change in the vector of the light flux transmitted through these crystals. This avoids his loss.
Excellent clarity and brightness. Such matrices respond in 25 ms. And their viewing angle will be steeper than that of TN, reaching as much as 160 °.
The color reproduction quality is also much higher in comparison with the same TN. They convey black color cleanly and deeply. But not perfect. The transmitted colors are quite distorted, depending on the viewing angle. Non-professionals will hardly see the difference. But not photographers. Therefore, these matrices are not suitable for working in a graphics editor.
Matrix resolution is a key parameter indicating the number of pixels that fit on the display in the horizontal and vertical directions. The transmission quality is ensured by high rates of these characteristics.
The most popular extensions today are:
- 1280 × 1024;
- 1280 × 800;
- 1024 × 768;
- 1366 × 768.
IPS (varieties. Super IPS, A-IPS, Dual Domain IPS) or Super TFT differ in the parallel arrangement of crystals and their SIMultaneous rotation moment. And all thanks to the presence of two electrodes at the bottom of each of the cells.
These matrices offer excellent contrast and color performance, delivering pure blacks from 170-180 ° viewing angles. Plus, the pictures look good when viewed from any vantage point.
Types of laptop matrices
There are three of them:
They differ from each other only in the arrangement of the matrix crystals. This is a determining factor in the degree of light transmission, and therefore the image quality.
Matrix coating type
Displays are covered with two types of materials:
Matte type of coating does not shine in bright light and almost does not stain. But it gives a dull image compared to a glossy display. However, working on such a laptop can be very productive.
On a glossy display, the picture will be seen better than on a matte one. It can be played great. The image will be saturated. However, bright light will be inconvenient due to glare.
This is also an important component. Its type for a laptop matrix can be:
CCFL. fluorescent lamp based. This technology has already outlived its usefulness, because it has a number of disadvantages, such as fragility, bulkiness, gluttony in energy consumption. Now it can only be found on inexpensive laptops.
LED. works on LEDs. Quite compact, but gives excellent display contrast. Not whiMSIcal and consumes a little energy. Used in many laptops.
Benefits of LCD displays
Of course, such displays have a number of advantages, including:
- compact size;
- lack of ripple and flicker effects;
- excellent protection against oscillations and electromagnetic interference.
In addition, crystals can be quickly reoriented by acting on them with an electric pulse. And the stronger they are, the less light the polarizer will let through. Also, the voltage level will affect the degree of brightness of the glow.
TN (types. DSTN and STN, TNFilm), made according to the most popular technology known since the distant 70s of the twentieth century. They use elongated non-rigid crystals that change their shape like twisted spirals.
But this type of matrix is guilty of the fact that the crystals in them move asynchronously. As a result, the flow of light goes in different directions, which affects the quality of the image when viewed from different angles.
The optimal viewing angle for them is straight, that is, strictly 90 °. A step to the left, a step to the right, and a couple of colors with contrast begin to float away. As a result, the image is dull, with poor color reproduction. Black tones slide to gray. And the contrast is extremely bad. But broken pixels shine like stars, bright dots.
TNFilm is a different story. A special type of film is used here. She then lines the surface of the laptop matrix. Due to this feint, it was possible to achieve a wider viewing angle of 140 ° in the horizontal plane. However, the vertical is still noticeably distorted.
Of course, its plus is that very little time is needed for the response (about 16-25 ms). And the cost of this matrix is small. Therefore, manufacturers do not hesitate to equip inexpensive models of their laptops with it. They are generally popular with students and are excellent at SIMple tasks.
What is the difference between an LCD TV and an LED TV?
In both cases, the TV is a liquid crystal matrix on which light falls. So this is the difference between LED TVs and LCDs in the light source. LCD TVs use fluorescent lamps for backlighting, and LED TVs use LEDs.
What is the Difference Between LCD and LED TVs?
The difference between LCD and LED TVs
In LCD-screens, fluorescent or fluorescent lamps provide backlighting. The LED screens are backlit by LEDs. Thus, we can say that we are talking only about the difference in the principles of screen backlighting, and not some completely new technology.
What makes monitors different?
Gaming monitors often differ from office and multimedia displays in their extended port selection. Since a high refresh rate requires a wide data channel, such displays are equipped with HDMI ports version 2.0 and / or DisplayPort 1.2 and newer.
What is lcd screen type? What is the Difference Between LED and OLED?
LED TVs are a type of LCD panel equipped with LED backlighting instead of the outdated lamp. … OLED TVs are based on organic light-emitting diodes (OLEDs) connected in a screen matrix. They do not need additional illumination, as they emit color themselves.
Which laptop is better for the eyes?
Matte screens are better for our eyes.
Perhaps the most striking characteristic of a laptop display is the type of finish, that is, matte or glossy. And this, in turn, increases eye strain and fatigue.
What is better LCD or LED monitor?
LCD vs LED: which monitor is better
So, LED screens have better contrast, so the colors on them look more colorful, expressive and colorful. … LED screens are thinner and less heavy. Another difference between these options is the service life. May 31, 2018.
What is the difference between LCD and LED?
The main difference between the two technologies is the type of liquid crystal backlighting. LCD screens are illuminated by fluorescent or fluorescent lamps. The LED models use more compact and energy efficient LEDs for this.
What is LCD TV?
Liquid crystal TV (abbreviated LCD TV; English. liquid crystal TV) is a flat panel TV with a matrix based on liquid crystals that requires backlight.
