Scientific Image - Organic Light-Emitting Diode

This is a photograph of an organic light-emitting diode (OLED). OLEDs are being used in the newest generation of television screens. An OLED is comprised of a thin organic film held between conductors. When electrical current is applied to the conductors, the film emits a bright light. Because OLEDs emit light, OLED-based displays do not require backlighting. That's why these displays are both thinner and more efficient than today’s common LCD screens, which require an additional internal light source. Several major electronics companies have recently introduced OLED-based television...
