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.

Characteristics of the TV matrix [/ caption] The matrix plays an important role in ensuring image quality by implementing a certain picture display technology. The most common are liquid crystal displays. There are also quantum dot matrices, OLED and laser TVs. Liquid crystal matrix device:
Matrix for TV - types, how to find out which one is on TV, which one is betterLiquid 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:

  1. Allows you to make the screen more compact and thin.
  2. High brightness, contrast and color quality.
  3. Even with the failure of several LED backlight crystals, the display quality remains high.
  4. Power consumption is 40% less compared to LCD displays.

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.

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:

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:

  1. If the TV has a TN-film matrix , you need to consider that it is gradually becoming obsolete. Such TVs are currently only in the budget segment. A feature of the screen is that even when turned off, the pixels glow. If there are broken ones among them , then this will be immediately visible. A small viewing angle allows you to watch video only from a perpendicular direction or from close to it. If you deviate further, then the contrast of the image will deteriorate. The strength of such monitors is a short response time (up to 2 ms).Matrix for TV - types, how to find out which one is on TV, which one is better
  2. S-PVA matrices are manufactured by Samsung. They demonstrate good quality, but have a negligible viewing angle. However, when viewed from a significant angle, the distortion remains subtle. Shows high-quality black color. Such a matrix has long been used in professional monitors for those involved in photography or video editing.
  3. The UV2A matrix type has recently entered the market. In terms of quality, it is only slightly inferior to the OLED matrix. It has a high level of color rendering. The depth of black reaches 0.02-0.06 nits. The viewing angle of such displays is significant. Such products are produced mainly by Sharp. They are also rarely seen in some Philips models.
  4. IPS and VA panels are now the most popular options for LCD panels. If the screen is off, then the light will not pass through. Unlike TN, dead pixels will not stand out in this situation. VA matrices are capable of rendering blacks with higher quality. When watching video on screens with IPS, you can enjoy significant viewing angles. They have a response time of over 5 ms.

The principle of operation of TN and IPS panels:
Matrix for TV - types, how to find out which one is on TV, which one is betterA feature of devices with quantum dots, which include QLED models, is the presence of a fourth layer in the composition of 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:
Matrix for TV - types, how to find out which one is on TV, which one is betterThe 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.

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:

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.

How to determine the type of matrix in your TV

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. [caption id="attachment_2762" align="aligncenter" width="900"]

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/x4mBM9Nvgqk

What are the most common breakdowns in matrices

The following checks must be performed not only when buying a TV, but also in the future. Thus, it will be possible to find out about the presence of the most common breakdowns. When buying, you need to test for
broken pixels . This is usually done by displaying an image with a high level of brightness on the screen. Dead pixels will be visible as black dots. [caption id="attachment_9946" align="aligncenter" width="600"]

Need to check the video speed. This can be verified by showing a fast-moving video. By displaying a picture with a lot of shades of gray, you can see how high the quality of the image is. It is important to check the quality of the white display. In this case, you need to make sure that there are no, for example,

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.
