What is OLED?
(SM) OLED Small Molecule Organic Light Emitting Diode.
The original technology developed to exploit the light emitting property of
some organic chemicals. Has been the basis of most commercial products to
date.
What is Hybrid LED?

2.2.1 기본구조
모든 OLED 장치의 emission은 같은 원리로 설명된다. Electron-hole 재결합에의한 고에너지 분자상태가 형성된다. 이러한 상태를 exciton이라고 하며, 이것은 고에너지를 가진 한 개의 분자처럼 행동한다. Exciton은 exciton lifetime period이후에 빛을 방출하게된다.(그림.1). 그림2는 구조를 개략적으
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
WHY OLED ?
Recent everyday machinery
Multifunctional
Portable
Convenient
E-book and reader
Not so common yet
Lots of text & multimedia
Easy to upgrade & update
Portable, but small screen
WHY OLED ?
Easily portable and
