First, Substrate is consists of a plastic or glass, a portion of the OLED is supportive.Anode is a role that make electron holes when current flows by removing electron. And the upper Conducting Layer is the place that Electron Holes is being created.Emissive Layer is the place accepting an electron from Cathode and produce light.
Emissive layer and conducting layer are called organic layer beca
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 : reco
2. OLED에 이용되는 다양한 고분자 재료
1) 정공 주입 재료(Hole Injection Materials)
OLED 소자에서 양극은 투명 전극으로 무기산화물인 ITO(Indium Tin Oxide) 글라스가 기판을 이루고 있으며 그 위에는 정공 주입층이 놓이게 된다. 정공 주입층은 정공 수송층과 ITO 사이의 계면 특성이 무기물과 유기물의 차이로
emitting property of
some organic chemicals. Has been the basis of most commercial products to
date.
What is Hybrid LED?
Hybrid LED compensate
the defect of OLED
Good color
Improved power efficiency
Low cost, large area
Flexibility
Hybrid LED made by inorganic/organic
material which has heterostructure
Usually, consisting of metal (or oxide)
and polymer
