What is the viewing distance of the LCD TV?

The relationship between the size of the LCD TV and the viewing distance and room size:

View straight distance within three meters, room size is less than 20 square meters, select 25-29 inches;

To see a straight line distance of about three meters, the size of the room is 20 to 30 square meters, choose 29-34 inches;

To see a straight line distance of about four meters, the room size is 30 to 40 square meters, choose 35-43 inches;

To view a straight line distance of more than four meters, the size of the room is more than 50 square meters, select the LCD TV more than 43 inches.

The ordinary CRT TV pays great attention to the viewing distance, because the early CRT TV has a large amount of radiation and the screen flickers. For flat-panel TVs: LCD TVs and plasma TVs have no flickering due to the stability of the picture, and the amount of radiation is very small. In particular, LCD TVs are often said to have no radiation. Most people do not pay attention to a reasonable viewing distance. In fact, no matter what kind of display technology TV is used, it needs a reasonable viewing distance to ensure the enjoyment of high-quality images and comfort and health.

The viewing distance and the size of the TV The larger the screen of the TV, the greater the required viewing distance. This is because the viewing angle is limited when the human eye is not rotating. A reasonable distance is required to allow people to not turn their eyes. In the case of the head and see clearly every corner of the TV picture. It is generally recommended that the viewing distance be 3-4 times the height of the TV.

The distance between the viewing distance and the distance between the TV and the TV refers to the distance between the screen pixels of the TV. It is proportional to the screen size and inversely proportional to the screen resolution. The screen with high resolution and low dot pitch has better picture detail. which performed. If you look at the distance too close and the screen is too large, the screen will be obviously meshed, and the flicker will seriously affect the screen effect. Therefore, it is hoped that TVs that are watched in close quarters will not only use small-screen TVs, but also pay attention to the style with the smallest dot pitch. On this aspect, LCD TVs have obvious advantages.

The distance between the viewing distance and the brightness of the TV The brightness of the TV differs greatly from 300-1000 nit. Higher two degrees will produce a harsh feeling, even burning eyes, too low brightness Eyes must be highly concentrated, very easy to fatigue, long-term use of low-brightness products more likely to suffer from myopia. The intensity of light in communication will decrease with distance. Generally, the energy of television is mainly spread in the range of up and down, 160 degrees, and so on. The theory requires that the light intensity transmitted to the human eye is between 85 and 110 nit. This is to ensure visual health. An ideal value. The viewing distance is usually about two-hundredths of the brightness of the TV screen.
