8.4 Organic LED

OLED is an abbreviation for Organic Light-Emitting Diode, device that sandwiches carbon-based films between two charged electrodes: a metallic cathode and a transparent anode (usually thin film of metal evaporated on a glass substrate).

OLEDs are commonly shaped as thin transparent sheets made from flexibile polymer, emitting bright light when biased.

OLEDs are already used as an screen in many portable electronic devices (cell phones, MP3 players, cameras, etc.). Several lighting companies are engaged in OLED research and development - including Philips, OSRAM, GE, Lumiotec, NovaLed, and others.
