How does OLED work?
Transport layer
Injection layer
Light : Electro phosphorescence
Light Intensity (Brightness)
-Thickness of organic layer
-Amount of current
OLED
:Organic Light Emitting Diode
Organic means…
→Electroluminescent layer is
:a film of organic compound
(ex. C2, H2, O2, other polymers)
not semiconductor →used in LED
1.Self-luminescence
The biggest difference between LCD is that it is self-luminescence. It means that the diode can emit the light itself so it has the good visibility although there is ligh
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

OLED is…
A light-emitting diode
in which the emissive electroluminescent layer is a film of orgarnic compound
which emits light in response to an electric current.
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
smaller screen
OR
Wider screen and
less portable ?
POLYMER OLED DISPLAY
