OLED 
organic light-emitting diode 
A display device that operates by sandwiching carbon-based films between two charged electrodes. OLED displays, originally developed by Kodak, are unlike LCDs in that they don't require backlighting; instead, they emit light themselves. OLED displays offer many advantages over LCDs, including less power consumption and brighter output, and are increasingly showing up in MP3 players and other portable devices, although TV-size displays are still in the prototype stage.
