What is the matrix used in TVs
When choosing a TV model, indicate the type of matrix used. Sometimes buyers do not have sufficient knowledge to evaluate the pros and cons that this or that screen has. In fact, the matrix is a system of a large number of transparent electrodes. Under the action of electrical signals, transparency, color and other features change depending on the type / type. The image is formed due to the formation of each point of the image. This is done at a very high speed so that viewers can see realistic moving images. When choosing between LED and LCD television matrices, the first option is considered by many to be more preferable. In plasma screens, the image is formed by illuminating the phosphor using ultraviolet rays. This gives high depth and color saturation. Plasma gives fast response and good viewing angles. Each type of matrix has certain features that you need to know. The main ones will be listed next. Liquid crystal displays will be considered first. In liquid crystal matrices, the displayed image is formed by dots, giving them the desired color shade. Each of them in most cases consists of three parts representing the primary colors: red, blue and green. There are also matrices that use four primary colors. The principle of operation of TN and IPS panels: In order to determine the type of matrix that is used in your TV, you can specify the exact model name. For many manufacturers, this code contains information about the type of matrix used. This can be illustrated by the following example. If we consider the QN65Q900RBFXZA model from Samsung, then you need to pay attention to the first two characters. “QN” means that a QLED matrix is used. The exact name can be found on the TV or on the box it was previously packed in.

Thus, it will be possible to find out about the presence of the most common breakdowns. When buying, you need to test for
Liquid crystal displays may use either LCD or LED technology. The principle of operation is that one of the layers of the screen is a layer of viscous liquid. Molecules in it can change their position under the action of electrical signals. In this case, their optical properties will change, creating the desired image on the screen. LCD and LED differ in the way they are backlit. In the first case, it comes from the edges of the screen, which reduces the quality of color reproduction, but reduces the thickness of the screen. In the second case, the backlight is located over the entire area of the screen, which allows you to get a higher image quality. Thus, the use of LED matrices has the following advantages:Popular types of television matrices in 2022 – matrix types VA, IPS, TN and others
Each such point on the screen is called a pixel. When the user sees the resolution, the first number expresses the number of rows and the second the number of columns. The larger these numbers, the more detailed the image is provided. In liquid crystal screens, the matrix consists of three layers. The colored elements are in the outer layer. The middle one consists of liquid crystals, and the bottom one provides illumination. Liquid crystal display device:
It uses white LED backlight. The middle layer can control light transmission from the bottom layer. If it is open, then the top layer acts as a color filter, giving the pixel the desired color. Next, we will consider the features of some varieties of LCD matrices, which you need to pay attention to:
A feature of devices with quantum dots, which include QLED models, is the presence of a fourth layer in the screen. It is designed to provide a higher quality white color as a backlight. This allows you to significantly improve color reproduction and increase the number of available color shades. In particular, this allows you to show both pure white and realistic black. Since the intrinsic glow of the pixels is not intense enough, an additional backlight is applied here. QLED displays are produced by Samsung, TCL and Hisense. Display Quality Comparison:
The advantage of OLED screens is a very high contrast ratio. Viewers can use even significant viewing angles for viewing. These screens have relatively lower power consumption and are more compact in size. The operation of such devices is based on the use of organic light emitting diodes. Their design does not use backlighting, which allows for a thinner display. Along with these advantages, they also have some disadvantages. The production of these devices is more expensive than for other types of matrices. Another problem is the different lifespan of LEDs of different colors.
As an example for comparison, we can consider the duration of operation of blue and green colors. They, respectively, will be equal to 15,000 and 100,000 hours of work. Thus, after prolonged use of such screens, a burn-in effect will appear, which will degrade the image quality. In such matrices, an additional white subpixel is sometimes used to form an image. Using four colors instead of three results in a reduction in screen resolution. OLED displays are high quality and expensive. They are actively used in their technology by Samsung, LG, Sony and Apple. Image quality comparison:
The use of laser technology is based on different principles than those previously described. Here the light does not come from the screen, but is only reflected by it. This reduces eye strain, but reduces the brightness of the image. Such matrices are distinguished by high image quality and excellent color reproduction. The disadvantage of such models is their higher price.

Labeling Samsung TV [/ caption] Another way to get this information is to use the main menu. It can be opened with the corresponding button on the remote control. Usually it contains an item that contains information about the TV. By opening it, you can get the necessary information. Sometimes you can determine the type of screen empirically. For example, if you click on the screen, and the image is distorted, then you can conclude that a VA or TN matrix is \u200b\u200bused. When the image quality deteriorates greatly when viewed from the side, we are most likely talking about TN. You can get the necessary information about the model by searching the Internet. Thus, not only technical data will be available, but also user reviews. How to find out what matrix is on the TV: https://youtu.be/x4mBM9NvgqkWhat are the most common breakdowns in matrices

How to choose a matrix when buying a TV
In order to choose a suitable matrix when buying, you need to pay attention not only to the technical characteristics of the screen, but also to what image quality it demonstrates in practice. At the same time, you need to be able to evaluate the permissible viewing angles, color reproduction quality and other parameters. If the buyer has the financial capacity for this, he should pay attention to laser matrices. You can also stop your attention on ULED or OLED models. At the same time, it is not recommended to buy those that use white subpixels. High-quality matrices are suitable not only for watching videos, but also for obtaining high-quality images in the gameplay. When choosing a relatively inexpensive option, it makes sense to pay attention to screens with VA matrices. In this case, you need to pay attention to the contrast, which should be no worse than 4000: 1.
A few examples of specific TVs with different types of matrices
Here we will talk about some models that use the most popular types of matrices. These TVs offer great value for money, delivering quality video for years to come.
Matrix VA, model LG 43NANO776PA 42.5″
The VA matrix is used here. The applied FRC technology allows to show more color shades. The thin body allows you to conveniently position the TV in almost any place convenient for the owner. A room light sensor is used to adjust the intensity of the picture and the features of the black color image. The advantages of this model are:
- Application of NanoCell technology.
- Nice and impressive design.
- High performance.
- Easy and convenient speaker connection for surround sound.
The cost is from 39000 rubles.
IPS, model Sony KD-55X81J 54.6″
One of the advantages of this model is the use of a powerful processor that uses TRILUMINOS PRO technology. Viewers can enjoy true-to-life color shading and excellent contrast. Unique algorithms for analyzing the color gamut of the image allow you to achieve an impressive display quality. When showing even rapidly changing scenes, there is no feeling of blur. The light sensor allows you to optimally adjust the image parameters. The advantages of this TV model can be considered the following:
- High quality display.
- The use of a powerful processor.
- Simple and clear interface.
- Fast response.
- Long TV life.
As disadvantages, they note that there are functions that are difficult to configure, as well as higher power consumption. The cost is from 71500 rubles.
