P3.91 indoor regular full color LED


1. Select high-quality LED chip, high luminous efficiency, small brightness attenuation, good display stability and reliability;

2, the use of a full range of anti-static measures, effectively reduce the damage to the LED tube caused by static electricity, control the annual xenon lamp rate in five parts per million;

3, advanced production and processing technology to ensure quality and longevity, the brightness difference of any two LEDs is plus or minus 10%, ensuring the brightness and color uniformity of the entire screen;

4, low cost, high pixel, fine and clear picture, good uniformity, good resolution of mosaic phenomenon, with good consistency;

5, using real pixel display, whether it is text or image, have a good display effect;

6, the viewing angle is large, the horizontal viewing angle and the vertical viewing angle can reach 120 ° or more, the graphics are not deformed in any range, and no color cast;

7, easy to maintain, can achieve a single point of maintenance, low maintenance costs;
