Physical indicators
Pixel pitch
Distance between adjacent pixels’ central part.
Density
The number of pixels in unit area, (Units: Point / m2)
There is certain calculation between the number of pixels and the pixel pitch.
Calculation formula: = 1 ÷ (pixel pitch)
The best viewing distance

Level up degree
LED (light emitting diode), pixel, module, constitutes the LED display where has concavo-convex error/ deviation/declination, the worse level up degree of LED display will cause/result in the uneven color of the LED display.
