Which matrix is ​​better ips or tft. Which matrix is ​​better, how do they affect vision? VA, MVA and PVA matrices

In the year 2007, buying another mobile phone, we evaluated its design, rarely paying attention to functionality and what’s more, the screen is color, not too small, and that’s great. Today, mobile devices can hardly be distinguished from each other, but the most important characteristic for many, what remains is the screen and not only its diagonal size, but also matrix type. Let's see what's behind the terms TFT, TN, IPS, PLS, and how to choose a smartphone screen with the required characteristics.

Types of matrices

Currently in modern mobile devices They use three technologies for the production of matrices based on:

• liquid crystal display (LCD): TN+film And IPS;
• on organic light-emitting diodes (OLED) – AMOLED.

Let's start with TFT(thin-film transistor), which is a thin-film transistor used to control the operation of each subpixel. This technology used in all of the above types of screens, including AMOLED, so comparing TFT and IPS is not always correct. The vast majority of TFT matrices use amorphous silicon, but TFTs on polycrystalline silicon (LTPS-TFTs) have also begun to appear, the advantage of which is reduced power consumption and higher pixel density (more than 500 ppi).

TN+film (TN)– the simplest and cheapest matrix used in mobile devices with small viewing angles, low contrast and low color accuracy. This type of matrix is ​​installed in the cheapest smartphones.

IPS (or SFT)- the most common type of matrix in modern mobile gadgets, which have wide viewing angles (up to 180 degrees), realistic color reproduction and provide the ability to create displays with high pixel density. This type of matrices has several types, let’s consider the most popular ones:

• AH-IPS– from LG;
• PLS- from Samsung.

It makes no sense to talk about advantages relative to each other, since the matrices are identical in properties and characteristics. You can distinguish a cheap IPS matrix by eye by its characteristic properties:

• fading of the picture when the screen is tilted;
• low color accuracy: an image with oversaturated or very dull colors.

Standing apart from LCD are matrices created on the basis of organic light-emitting diodes (OLED). Mobile devices use a type of OLED technology - matrix AMOLED, demonstrating the deepest blacks, low power consumption and extremely rich colors. By the way, the life of AMOLED is limited, but modern organic LEDs are designed for at least three years of continuous operation.

Conclusion

The highest quality and brightest image on this moment provide AMOLED matrices, but if you are looking at a non-Samsung smartphone, I recommend an IPS screen. Mobile devices with a TN+film matrix are simply technologically outdated. I recommend not buying a smartphone with AMOLED screen, which has a pixel density of less than 300 ppi, this is due to the problem of subpixel patterns in this type matrices

Perspective matrix type

– the most promising displays based on quantum dot technology. Quantum dot is a microscopic piece of semiconductor in which quantum effects play an important role. QLED matrices in the future will have better color rendition, contrast, more high brightness and low power consumption.

Technology does not stand still, and the production of liquid crystal screens is no exception. However, due to the constant development and release of new technologies in the manufacture of screens, as well as due to special marketing approaches to advertising, many buyers when choosing a monitor or TV may have a question, which is better IPS or TFT screen?

To answer the question posed, you need to understand what IPS technology is and what a TFT screen is. Only knowing this will you be able to understand the difference between these technologies. This in turn will help you do right choice screen that will fully meet your requirements.

1. So, what is a TFT display?

As you may have guessed, TFT is an abbreviated name for the technology. It completely looks like this - Thin Film Transistor, which translated into Russian means thin-film transistor. Essentially, a TFT display is a type of liquid crystal screen that is based on an active matrix. In other words, this is a regular active matrix LCD screen. That is, the molecules of liquid crystals are controlled using special thin-film transistors.

2. What is IPS technology

IPS is also short for In-Plane Switching. This is a type of active matrix LCD display. This means that the question of which is better TFT or IPS is erroneous, since they are essentially the same thing. More precisely, IPS is a type of FTF display matrix.

IPS technology received its name due to the unique arrangement of electrodes, which are located on the same plane with the liquid crystal molecules. In turn, the liquid crystals are located parallel to the screen plane. This solution made it possible to significantly increase viewing angles, as well as increase the brightness and contrast of the image.

Today there are three most common types of active TFT matrices displays:

• TN+Film;
• PVA/MVA.

Thus, it becomes obvious that the difference between TFT and IPS is only that TFT is a type of LCD screen with an active matrix, and IPS is the same active matrix in a TFT display, or rather one of the types of matrix. It is worth noting that this matrix is ​​the most common among users around the world.

3. What is the difference between TFT and IPS displays: Video

The common misconception that there is any difference between TFT and IPS arose due to the marketing gimmicks of sales managers. In an attempt to attract new customers, marketers do not distribute complete information about technology, which allows you to create the illusion that a completely new development is coming into the world. Of course IPS is more new development, rather than TN, but choose which one better display TFT or IPS is not possible for the reasons stated above.

As is usually the case with abbreviations used to denote specifics and technical characteristics, there is confusion and substitution of concepts in relation to TFT and IPS. Largely thanks to unqualified descriptions electronic devices In catalogues, consumers pose the question of choice initially incorrectly. So, the IPS matrix is ​​a type of TFT matrix, so it is impossible to compare these two categories with each other. However, for Russian consumers, the abbreviation TFT often means TN-TFT technology, and in this case a choice can already be made. So, when talking about the differences between TFT and IPS screens, we will mean TFT screens made using TN and IPS technologies.
TN-TFT– technology for making a matrix of a liquid crystal (thin-film transistor) screen, when the crystals, in the absence of voltage, are rotated to each other at an angle of 90 degrees in the horizontal plane between two plates. The crystals are arranged in a spiral, and as a result, when fed maximum voltage The crystals rotate in such a way that when light passes through them, black pixels are formed. Without tension - white.
IPS– technology for making a matrix of a liquid crystal (thin-film transistor) screen, when the crystals are located parallel to each other along a single plane of the screen, and not spirally. In the absence of voltage, the liquid crystal molecules do not rotate.
In practice the most important difference IPS matrix from TN-TFT matrix consists of elevated level contrast due to almost perfect black color display. The picture is clearer.
The color rendering quality of TN-TFT matrices leaves much to be desired. Each pixel in this case may have its own shade, different from the others, resulting in distorted colors. IPS already treats images much more carefully.
The response speed of TN-TFT is slightly higher than that of other matrices. IPS takes time to rotate the entire array of parallel crystals. Thus, when performing tasks where drawing speed is important, it is much more profitable to use TN matrices. On the other hand, in everyday use a person does not notice the difference in response time.
Monitors and displays based on IPS matrices are much more energy-intensive. This is due high level voltage required to rotate the crystal array. Therefore, the tasks of energy saving in mobile and portable devices TN-TFT technology is more responsible.
IPS-based screens have wide viewing angles, meaning they do not distort or invert colors when viewed at an angle. Unlike TN, angles IPS review are 178 degrees both vertically and horizontally.
Another difference that is important for the end consumer is the price. TN-TFT today is the cheapest and most widespread version of the matrix, so it is used in budget models electronics.

TheDifference.ru determined that the difference between TFT (TN-TFT) and IPS screens is as follows:

IPS screens are less responsive and have longer response times.
IPS screens provide better color reproduction and contrast.
The viewing angles of IPS screens are significantly greater.
IPS screens require more power.
IPS screens are more expensive.

Oddly enough, choose high quality display computer monitor or laptop can only be done experimentally. This article will help you understand the parameters that you should pay attention to when choosing a monitor or laptop.

How to choose a laptop monitor or display with ideal characteristics?

A high-quality display has a huge advantage in multimedia tasks on a PC, and in relation to a laptop it’s half the difference. Take a look at this short list of display issues to watch out for when purchasing a new mobile computer or PC monitor:

• low brightness and contrast characteristics
• small viewing angles
• glare

Replacing a laptop screen is more difficult than buying one new monitor For desktop computer, not to mention installing a new LCD matrix into a mobile computer, which cannot be done in all cases, so selecting a laptop screen should be approached with full responsibility.

Let me remind you once again that you should believe the promises of advertising materials. retail chains and computer manufacturers cannot. Having finished reading mobile computer monitor and display selection guide, you can find difference between TN matrix and IPS matrix, evaluate the contrast, determine the required brightness level and other important parameters of the liquid crystal screen. You'll save time and money searching for a PC monitor and laptop display by choosing a quality LCD screen instead of a mediocre one.

Which is better: IPS or TN matrix?

The screens of laptops, ultrabooks, tablets and other portable computers typically use two types of LCD panels:

• IPS (In-Plane Switching)
• TN (Twisted Nematic)

Each type has its own advantages and disadvantages, but it is worth considering that they are intended for different groups consumers. Let's find out which type of matrix is ​​right for you.

IPS displays: excellent color reproduction

Displays based on IPS matrices have the following advantages:

• large viewing angles - regardless of the side and angle of human gaze, the image will not fade and will not lose color saturation
• excellent color reproduction - IPS displays reproduce RGB colors without distortion
• have a fairly high contrast.

If you are going to do pre-production or video editing, you will need a device with this type of screen.

Disadvantages of IPS technology compared to TN:

• long pixel response time (for this reason, displays of this type are less suitable for dynamic 3D games).
• monitors and mobile computers with IPS panels tend to be more expensive than models with screens based on TN matrices.

TN displays: inexpensive and fast

Liquid crystal displays are currently the most widely used matrices made using TN technology. Their advantages include:

• low cost
• low power consumption
• response time.

TN screens perform well in dynamic games - for example, first-person shooters (FPS) with fast scene changes. For similar applications a screen with a response time of no more than 5 ms is required (for IPS matrices it is usually longer). Otherwise, various kinds of visual artifacts may be observed on the display, such as trails from fast-moving objects.

If you want to use it on a monitor or laptop with a stereo screen, it is also better for you to give preference to a TN matrix. Some displays this standard capable of updating the image at a speed of 120 Hz, which is a necessary condition for operation of active stereo glasses.

From disadvantages of TN displays It is worth highlighting the following:

• TN panels have limited viewing angles
• mediocre contrast
• are not capable of displaying all colors of the RGB space, so they are not suitable for professional editing images and videos.

Very expensive TN panels, however, do not have some characteristic disadvantages and are close in quality to good IPS screens. For example, in Apple MacBook Pro with Retina uses a TN matrix, almost as good as IPS displays in terms of color rendering, viewing angles and contrast.

How to distinguish IPS from TN

If you liked the monitor or laptop, and specifications display are not known, you should look at its screen from different angles. If the image becomes dull and its colors are greatly distorted, you have a monitor or mobile computer with a mediocre TN display. If, despite all your efforts, the picture has not lost its colors - this monitor with a matrix made using IPS technology, or with high quality TN.

Attention: avoid laptops and monitors with matrices, which show strong color distortion at high angles. For games choose computer monitor with an expensive TN display, for other tasks it is better to give preference to an IPS matrix.

Important parameters: monitor brightness and contrast

Let's look at two more important parameters display:

• maximum level brightness
• contrast.

There's no such thing as too much brightness

For indoor work artificial lighting a display with a maximum brightness level of 200–220 cd/m2 (candelas per square meter). The lower the value of this setting, the darker and dimmer the image on the display will be. I do not recommend buying a mobile computer with a screen whose maximum brightness level does not exceed 160 cd/m2. For comfortable work Outdoors on a sunny day you will need a screen with a brightness of at least 300 cd/m2. IN general case The higher the brightness of the display, the better.

When purchasing, you should also check the uniformity of the screen backlight. To do this, you should reproduce white or dark blue color on the screen (this can be done in any graphic editor) and make sure there are no light or dark spots across the entire surface of the screen.

Static and staggered contrast

Maximum level static contrast screen is the ratio of the brightness of successively displayed black and white colors. For example, a contrast ratio of 700:1 means that when outputting white, the display will be 700 times brighter than when outputting black.

However, in practice, the picture is almost never completely white or black, so for a more realistic assessment, the concept of checkerboard contrast is used.

Instead of sequentially filling the screen with black and white colors, a test pattern is displayed on it in the form of a black and white chessboard. This is a much more difficult test for displays because due to technical limitations you cannot turn off the backlight under the black rectangles and simultaneously illuminate with maximum brightness white. A good checkerboard contrast for LCD displays is considered to be 150:1, and an excellent contrast is 170:1.

The higher the contrast, the better. To evaluate it, display a chess table on your laptop display and check the depth of black and brightness of white.

Matte or glossy screen

Probably many people paid attention to the difference in matrix coverage:

• matte
• glossy

The choice depends on where and for what purposes you plan to use the monitor or laptop. Matte LCD displays have a rough matrix coating that does not reflect external light well, so they do not glare in the sun. Obvious disadvantages include the so-called crystalline effect, which manifests itself in a slight haze of the image.

The glossy finish is smooth and better reflects the light emitted external sources. Glossy displays, as a rule, are brighter and more contrasting than matte ones, and the colors on them seem more saturated. However, such screens produce glare, which leads to premature fatigue when long work, especially if the display has insufficient brightness.

Screens with a glossy matrix coating and having insufficient brightness reserves reflect the surrounding environment, which leads to premature fatigue of the user.

Touch screen and resolution

Windows 8 became the first operating system Microsoft system, which had a huge impact on the development of screens mobile computers, in which optimization is clearly visible graphical shell under touch screens. Leading developers produce laptops (ultrabooks and hybrids) and all-in-one PCs with touchscreens. The cost of such devices is usually higher, but they are also more convenient to manage. However, you will have to accept that the screen will quickly lose its presentability appearance due to greasy fingerprint marks, and wipe it regularly.

The smaller the screen and the higher its resolution, the large quantity The number of points forming the image is per unit area, and the higher its density. For example, a 15.6-inch display with a resolution of 1366x768 pixels has a density of 100 ppi.

Attention! Do not buy monitors with screens with a dot density of less than 100 dpi, as they will show visible grain in the image.

Before Windows release 8 high density pixels did more harm than good. Small fonts on small screen With high resolution it was very difficult to see. Windows 8 has new system adaptation to screens with different densities, so the user can now choose laptop with such diagonal and display resolution as it deems necessary. The exception is for video game fans, as running games at ultra-high resolutions will require a powerful graphics card.

IPS or TFT - which is better to choose? More recently, I was faced with the need to give a person a reasonable answer to this question when buying a tablet. Knowing for sure what was already on everyone’s lips, I was ready to immediately give an answer. But still, I decided to study this topic a little in order to reinforce what was said compelling reasons. I had to dig through the information a little and even... To understand the situation, I’ll say right away that we were talking about buying a reliable used tablet. As it turned out, this also contributes to the final decision regarding what is better - an IPS or TFT matrix. Even if you need to buy new tablet or smartphone, the information below will also be relevant and useful. So, let's begin our short review.

A little about the technologies used to produce IPS screens

Although most modern displays have liquid crystals, each case can use a little various technologies leading to differences in the characteristics of the final product. Terminology used throughout may vary. Therefore, in order not to be misled regarding TFT or IPS monitors, the following should be noted.

First and most importantly, we separate the weeds from the chaff: IPS technology is not anything different compared to TFT. It is TFT – or rather, one of its implementations. On the other hand, "our" person called TFT understands TFT-TN.

Thus, the comparison is made between two representatives of TFT matrices: IPS or TN. Regarding the technologies used:

• TFT (we understand that we are talking about TFT-TN). Liquid crystal display (thin film transistors). The crystals are arranged spirally in the matrix body between two plates. The formation of an image occurs due to the rotation of the crystal molecules. If there is no voltage, their horizontal rotation angle is 90 degrees, while they have White color. At the maximum applied voltage, the rotation is carried out at an angle at which, when light passes through the crystal, it turns black. So, depending on the voltage applied to the crystals, they change their color.
• IPS (actually TFT-IPS). The same crystals, only their location is parallel to each other. When there is no voltage, the crystal molecules are not rotated.

Now let's move on to the main question: ? Which display should you choose?

IPS or TFT - which is better? Differences between screens in image quality

The key features of any monitor, display, IPS or TFT screen are, first of all, determined by the quality of the picture display. In turn, quality can be broken down into indicators such as contrast and viewing angle.

When we're talking about about the IPS matrix, it significantly outperforms TFT in terms of image contrast. This is achieved by almost perfect reproduction of black crystals. Namely, the display of black directly affects such an indicator as contrast. In TFT displays, individual pixels (when displaying black and other colors) may have a slightly “own” tint, which leads to distortions in the color of the image.

An important factor influencing the choice of mobile device screen is the viewing angle. This indicator is especially important if the device is to be used together with others, for example, showing a photo of a recent trip to the sea. With a viewing angle of 178 degrees from any side, the IPS matrix undoubtedly wins, allowing several of your friends or colleagues to enjoy the image without distortion. This is also important to consider when purchasing a particular device.

Responsive speed of IPS and TFT display

The apparent advantage of a TFT display over an IPS screen is high speed response. Here he has no competitors. At the same time, the IPS matrix needs more time to rotate an array of crystals that are located in parallel.

This fact leads to the obvious conclusion that in devices whose purpose is critical to display speed, it is still better to use TFT. On the other hand, when it comes to everyday use (as a tool for studying, communicating via the Internet and other tasks), this difference almost invisible to the human eye, and is revealed only through the use of special technical tests. Therefore, when choosing a screen type, in most cases, preference should be given to an IPS matrix.

Which matrix needs more power - IPS or TFT?

There are other differences that we continue to list. How is the energy consumed in batteries of screens made using different technologies? There are obvious differences. The energy consumption of IPS is actually higher. Not only more time, but also more voltage is required to rotate the crystals of this type of matrix. The logical conclusion is an increased load on the battery. Therefore, when purchasing used devices, when it is obvious that the battery is no longer new, this fact must be carefully weighed. If it is purchased new phone, tablet or smartphone, and its use requires a long stay out of reach of the mains, it is better to focus on high-quality TFT matrices.

Cost of devices with different types of displays

Price IPS screens always higher. You can pay attention to this by filtering out devices with this type of matrix in any online store. It should be said that IPS is used in almost all modern devices, gradually replacing TFT. At the same time, if you only need the equipment to make a call, what's the point of paying extra for a screen whose benefits won't be used? Moreover, if this increases the overall energy consumption of a smartphone or tablet.

TFT or IPS - which is better? Which matrix should I choose?

So, if you need a modern, high-quality tablet with which you can not only work, but also comfortably show high-quality photos to friends, definitely choose only devices with an IPS matrix. When paying attention to manufacturers' markings, do not forget that TFT includes both TN and IPS matrices. But this is not all of their types. Knowing which of these two types of matrices is better - TFT or IPS, and wanting to buy a tablet, smartphone or phone, contact any of the trusted online stores (Rozetka, Eldorado, Citrus and others), which provide a full range of these products, with the ability to filter according to the most significant parameters.

By the way, a person who bought a tablet with an IPS matrix, which was delivered to him from Poland, was satisfied with it and constantly admires the comfort of using the device even on a sunny day. Facts, they say, are stubborn things.
