What's the difference between a mobile phone LED screen and a normal screen?

LED screen is better than ordinary screen, and LED has advantages over ordinary screen in brightness, power consumption, viewing angle and refresh rate.

LED display screen has always been limited by the performance and color of LED itself. At present, ultra-high brightness AlGaInP, TS-AlGaAs and InGaN LED can provide bright red, yellow, green and blue colors, which can fully meet the requirements of full-color large screen display. The led display screen can be assembled into various structures according to the pixel size, and the diameter of small pixels is generally less than 5 mm One T- 1(3/4) LED lamp is used for monochrome display, and one two-color T- 1(3/4) LED lamp is used for two-color display, while three T- 1 red, green and green LEDs are needed for full-color display.

Large pixels are composed of many T- 1(3/4) red, green and blue LED lights. Using InGaN(480nm) blue, InGaN(5 15nm) green and ALGaAS(637nm) red LED lamps as the three primary colors of the LED display screen can provide realistic full-color performance with a wide range of colors, including cyan, green and red. , which basically conforms to the TV color range specified by the International Television Systems Committee (NTSC).
