In recent years, LED display is a relatively hot new media technology. Compared with other display technologies such as LCD screens and projections, LED displays have the advantages of bright colors, stable display, long service life, and wide viewing range. They are used in commercial advertising, intelligent monitoring, high-end conferences, command centers and other fields. Has been applied and developed. For users, the viewing distance (ie, viewing distance) of the LED display is very important, and it will affect the coverage of advertisements and the viewing angle of users. So, how should the LED display's * and long-view distance be calculated?  

　　

To understand the calculation method of the viewing distance of the LED display screen, it is necessary to understand the point spacing of the LED display screen. The dot pitch of the LED display refers to the center distance between each pixel in the LED display and each adjacent pixel. The dot pitch is usually expressed by P, and the calculation unit is mm. P10 means the LED The pixel pitch of the display is 10mm. Generally speaking, the calculation formula for calculating LED display screen* and long-distance viewing distance in the industry is as follows:

 

RGB color mixing distance The distance between three colors mixed into a single color: LED full-color display viewing distance = pixel pitch (mm) × 500 ~ pixel pitch (mm) × 1000

 

The minimum viewing distance can display a smooth image distance: LED display visual distance = pixel pitch (mm) × 1000

 

Appropriate viewing distance The distance at which the viewer can see a highly clear picture: LED display * Viewing distance = pixel pitch (mm) × 3000 ~ pixel pitch (mm) × 1000

 

Far viewing distance: LED display far viewing distance = screen height (m) × 30 (times).
