Short for polymer
, or polymeric, light-emitting diode
, a backlighting, illumination and display technology. Polymers
are substances formed by a chemical reaction in which two or more molecules combine to form larger molecules. PLEDs are thin film displays that are created by sandwiching an undoped
conjugated polymer between two proper electrodes at a short distance. The polymer emits light when exposed to electricity. PLEDs enable full-spectrum color displays and are relatively inexpensive compared to other display technologies such as LCD
and require little power to emit a substantial amount of light.
