본문내용
An organic light emitting diode (OLED) is a solid state device like the LED but composed of several layers in which the emissive electroluminescent layer is a film of organic compounds which emit light in response to an electric current.
Function of each part
Cathode : injecting electron composed of metal
Anode : injecting hole composed of transparent ITO
Emissive polymer : recombination between hole and electron
Conducting Polymer : transporting holes
For many reasons; Less weight, flexible, fast response, lower power consumption and wide viewing angle OLED is very useful device for improving quality of human being, but still there are problems…
