# Calculation method of several main parameters of LED electronic screen

When purchasing any LED electronic screen, we are not an aimless choice, but order it according to our needs and environment to achieve the ideal effect, which is inseparable from the calculation of point spacing and sight distance of LED electronic screen, so as to give full play to the maximum role of LED electronic screen.

First, the calculation method of point spacing: the center distance from each pixel to each adjacent pixel; Each pixel can be one LED lamp (such as PH10 (1R)), two LED lamps (such as PH16 (2R)), three LED lamps (such as PH16 (2R1G1B)), and the point spacing of P10 is 10mm; Point spacing of p16: 16mm; The point spacing of P18 is 18mm.
Second, length and height calculation method: point spacing × Points = length / height
For example: PH16 length = 16 points × 1.6 cm = 25.6 cm, height = 8 points × 1.6㎝=12.8㎝
PH10 length = 32 points × 1.0 cm = 32 cm, height = 16 points × 1.0㎝=16㎝
Third, the calculation method of the number of modules used in the screen: total area ÷ module length ÷ module height = the number of modules used
For example, the number of modules used for 10 square PH16 outdoor monochrome LED electronic screens is equal to:
10 M2 ÷ 0.256 m ÷ 0.128 M = 305.17678 ≈ 305 PCs
More accurate calculation method: the length uses the number of modules × Height: number of modules used = total number of modules used
For example, the number of modules used for PH16 monochrome LED electronic screen with length of 5m and height of 2m:
Number of long use modules = 5m ÷ 0.256 M = 19.53125 ≈ 20
Number of high use modules = 2m ÷ 0.128m = 15.625 ≈ 16
Total number of modules used = 20 × 16 = 320
Fourth, calculation method of visual distance of LED electronic screen:
RGB color mixing distance the distance that three colors are mixed into a single color: LED full-color screen viewing distance = pixel spacing (mm) × 500/1000
The minimum viewing distance is the distance that can display smooth images: visual distance of LED electronic screen = pixel spacing (mm) × 1000/1000
The most suitable viewing distance is the distance that the viewer can see a highly clear picture: the best viewing distance of LED electronic screen = pixel spacing (mm) × 3000/1000
Furthest viewing distance: furthest viewing distance of LED electronic screen = screen height (m) × 30 (Times).
