In recent years, LED display is a relatively hot new media technology. Compared with LCD screen and projection and other display technologies, LED display has bright colors, stable display, long service life, wide visual range and other advantages, and it has been applied and developed in commercial advertising, intelligent monitoring, high-end conference, command center and other fields. For users, the viewing distance (visual range) of LED display is very important, which will affect the coverage of advertising and the viewing Angle of users. So, how to calculate the best and most distant viewing range of LED display?
To understand the calculation method of the line-of-sight of the LED display, we first need to understand the point spacing of the LED display. The dot spacing of the LED display screen refers to the center distance between each pixel in the LED display screen and each adjacent pixel. The dot spacing is usually represented by P, and the unit of calculation is mm. P10 means that the pixel spacing of this LED display screen is 10mm. Generally speaking, the industry calculation formula for the best and most distant viewing distance of LED display screen is as follows: RGB color mixing distance distance from three colors to a single color: LED full color screen line-of-sight = pixel spacing (mm) x 500 ~ Pixel spacing (mm) x 1000. The minimum viewing distance can display the smooth image distance: LED display visual distance = pixel spacing (mm)×1000. The distance at which the viewer can see the highly clear picture: the best viewing distance of the LED display = pixel spacing (mm)×3000 ~ Pixel spacing (mm)×1000. Maximum viewing distance: Maximum viewing distance of LED display = screen height (m)×30(times)
