OLED is an organic light-emitting diode, which can be used for display. With OLED, there is no need for backlight. It can emit light and develop color, which can replace LCD; At present, OLED is used for mobile phone screen display (such as ultra-thin mobile phone), and large screen display OLED has not been commercialized..
