콜로이드란?
콜로이드는 혼합물의 일종으로, 나노미터에서 마이크로미터 사이의 크기를 갖는 입자들로 구성된 것을 가리킨다. 콜로이드는 입자가 균일하게 퍼져 용매 속에 떠다니는 양상을 띤다.

organic light emitting diode(OLED)
LED's emissive electroluminescent layer is composed of a film of organic compounds.
This layer of organic semi-conductor material is formed between two electrodes, where at least one of the electrodes is transparent.
OLED can be used in many display devices.
Active matrix OLED has an integrated electronic backplane made from thin film transistor

Each pixel addressed independently
Release the color using not the RGB illuminant but the filter after emitting the light using white illuminant.
Advantage of WOLED
Unpatterned emitting layer(no masks)
Aperture ration not affected by RGB patterning Higher contrast ratio
Enabled by high efficiency white with less power
Reduced differential aging
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.
