OLED
Organic Light Emitting Diodes also known as Light Emitting Polymer (LEP) and Organic Electro-Luminescence (OEL).
They comprise any light-emitting diode (LED) whose emissive electroluminescent layer is comprised of a film of organic compounds.
A great benefit of OLED displays over traditional liquid crystal displays (LCDs) is that OLEDs do not require a backlight to function. Thus they draw far less power and, when powered from a battery, can operate longer on the same charge. OLED-based display devices can be more effectively manufactured than LCDs and plasma displays, but degradation of OLED materials has limited the use of these materials.
