Diagonal size and types of television signals

First you need to decide on a budget and decide what is preferable for you to a large diagonal or a high technological class of TV. If all you need is a large screen size, then choose models with the most inexpensive features. If you go so that your TV has all the modern features, and the budget is limited, it makes sense to save on the size of the diagonal.

But you can find a middle ground and purchase a TV with a good screen size and even if not with the latest developments, but still with modern technology.

TV signal at your home

Before buying a TV, check the quality of the signal source in your home. Today, there are several types of television.

  • Broadcast Television (SD) usually has a low signal quality, so if you plan to watch mostly only such television, then you don’t need a big tap. On the contrary, due to the low quality of the original signal, the large screen is only able to emphasize all the imperfections of the image.
  • High definition image (HDTV) occurs more and more often, more and more satellite and cable channels broadcast in high resolution 1920 × 1080 pixels. In this format, a large screen size can only emphasize all the advantages of the image.
  • Ultra High Definition Television (UHDTV). The Ultra HD format is the newest and so far rare. Image resolution 3840 × 2160 pixels allows you to watch TV from a very close distance without loss of quality, since even near you will not see the individual points that make up the image.

Types of TV screens

Since plasma TVs were discontinued, two main types of TVs remained: LCD TVs and with organic LEDs.


Liquid crystals are the most common technology to date. TVs with such displays are light weight and low power consumption. LCD displays are easy to manufacture, which leads to their low cost and a wide variety of models.

Organic LEDs (OLED)

A relatively new technology, which uses organic LEDs in the form of a panel, each LED is an independent light source. That is, there is no need for a backlight unit, as in LCD displays, which makes the picture better, and the cases are even thinner. Such screens are very expensive and represented by a narrow range in our market, at the moment you can find TVs only with a diagonal of 55 inches.

Due to the lack of plasma TVs on the market and the high cost of OLED technology, your choice is likely to fall on LCD displays, so we will tell you more about them.

Varieties of matrices and backlights in LCD displays

The matrix and the type of backlight are the main factors that are responsible for image quality.

Matrix TN

To date, such a matrix can only be found on TVs of the lowest class with a screen size of up to 32 inches. The picture is characterized by normal brightness and contrast, but viewing angles are very limited, especially vertically. The advantages of this matrix include its low cost.

Matrix VA

It is used both in high-end televisions, as well as in middle and lower class. In all respects, it is better than the previous matrix, has greater brightness, contrast, has wider viewing angles, which are better only with the IPS matrix. The image looks good indoors with dim light.

Matrix IPS

Of all the types of matrices intended for LCD displays, the IPS matrix has the widest viewing angle. In bright light, the image looks good. In contrast, inferior to the matrix VA.

Many modern TVs use the last two matrices, in terms of their characteristics and price category they are very similar.

The following backlight types are used on LCD screens:

  • Side lighting (EDGE LED) meets quite often. Light sources are located only on the sides of the screen, which saves electricity consumption. This type of backlight allows you to make TV cases as thin as possible. The disadvantages include the uneven distribution of light, which can lead to the formation of brighter areas in the image.
  • Direct backlight (Direct LED) rarely used. This type of backlight eliminates the uneven distribution of brightness, but the TV screen will no longer be as thin as with side illumination.
  • Dynamic local backlight is the most efficient type of backlight for LCD displays. The backlight consists of a group of LEDs that can change the degree of lighting, adjusting to the image. This improves the contrast of the image, and the backlight becomes more even. There are very few models with local illumination on the market, it can only be found in high-end models at a very high price.

3D format and Smart TV

Format 3D

The technology of forming three-dimensional images is found in televisions of different classes, moreover, there is a decrease in demand for this format for home television. Today you can find modern models where this function is already excluded.

Two technologies for forming a three-dimensional image are used:

  1. Active technology.

The main difference is that glasses for watching TV must have their own energy source, batteries or a rechargeable battery. The image is formed at a double frequent, the image is displayed for each eye in turn, and 3D glasses transform the image so that we see it three-dimensional.

The negative point is that the glasses require recharging or changing batteries, the image flickers slightly, which can tire your eyes when viewing it for a long time. The brightness of the picture decreases, but at the same time, it is characterized by high definition. This technology is well suited for home viewing in a dark room.

  1. Passive technology.

This technology is also called polarizing, because the princes of work are based on this physical phenomenon. Two images are displayed simultaneously on the screen, thereby dividing the screen into even and odd sections. Special glasses have different polarization in each lens, thereby a person sees two images at once, which are superimposed and form a three-dimensional image.

Due to the fact that the picture does not flicker, viewing does not tire the eyes so much. The brightness is better than with active technology, which allows you to watch movies in bright light. Glasses do not require any power sources. But the image decreases clarity and detail.

Smart Tv

Translated into Russian as “smart TV” - this is a technology for integrating TV and the Internet, found in most modern models. Connecting to the World Wide Web expands the capabilities of the TV, making it more like a computer. You can use the browser to find the necessary information, download and use various applications, watch online movies, without using a television signal.

When choosing a Smart TV, we recommend that you pay attention to the following points: simplicity and convenience management; speed of work; what applications are installed; is there voice control and built-in Webcam.
