[0002] LED display is a display device that uses light-emitting diodes (LEDs) as light sources. It is widely used in various occasions, including advertising, stadiums, shopping malls, traffic signs, stage performances, etc. Compared with traditional liquid crystal displays (LCDs), LED displays have many significant advantages. The brightness of LED displays is much higher than that of traditional LCD displays, and they can still be clearly seen in the sun, so they are very popular in outdoor advertising, stadiums and other occasions.
