Calculation of best and farthest viewing distance for LED display

In recent years, LED display is a relatively hot new media technology. Compared with other display technologies such as LCD screen and projection, LED display has the advantages of bright colors, stable display, long service life, and wide visual range, which makes it suitable for commercial advertising, intelligent monitoring, high-end conferences, command centers and other fields. been applied and developed. For users, the viewing distance (ie viewing distance) of the LED display is very important, which will affect the coverage of advertisements and the viewing angle of users. So, how should the best and farthest viewing distance of the LED display be calculated?

To understand the calculation method of the viewing distance of the LED display, you first need to understand the point spacing of the LED display. 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 represented by P, and the unit of calculation is mm. P10 means the LED The pixel pitch of the display is 10mm. The formula for calculating the best and farthest viewing distance of the LED display in the industry is as follows:

Best and farthest viewing distance calculation method for LED display

RGB color mixing distance The distance at which three colors are mixed into a single color: LED full-color screen viewing distance = pixel spacing (mm) × 500 ~ pixel spacing (mm) × 1000

Minimum viewing distance The distance at which a smooth image can be displayed: LED display viewing distance = pixel pitch (mm) × 1000

The most suitable viewing distance The distance at which the viewer can see a highly clear picture: the best viewing distance of the LED display = pixel pitch (mm) × 3000 ~ pixel pitch (mm) × 1000

The farthest viewing distance: the farthest viewing distance of the LED display = screen height (m) × 30 (times)
