OLED (Organic Light-Emitting Diode) is a self light-emitting technology composed of a thin, multi-layered organic film placed between an anode and cathode. In contrast to LCD technology, OLED does not require a backlight.
 
OLED possesses high application potential for virtually all types of displays and is regarded as the ultimate technology for the next generation of flat-panel display
