Abstract :
OLED’s are simple solid-state devices
(more of an LED) comprised of very thin films of organic compounds in the
electro-luminescent layer. These organic compounds have a special property of creating light when electricity
is applied to it. The organic compounds are designed to be in between two
electrodes. Out of these one of the electrodes should be transparent. The
result is a very bright and crispy display with power consumption lesser than the usual LCD and LED.
An organic light emitting diode (OLED)
is a light-emitting diode (LED) in which the emissive electroluminescent layer
is a film of organic compounds which emit light in response to an electric
current. This layer of organic semiconductor material is situated between two electrodes.
Generally, at least one of these electrodes is transparent.
1. Cathode (−).
2. Emissive Layer.
3. Emission of radiation.
4. Conductive Layer.
5. Anode (+).
A typical OLED is composed of a layer
of organic materials situated between two electrodes, the anode and cathode,
all deposited on a substrate. The organic molecules are electrically conductive
as a result of delocalization of pi electrons caused
by conjugation over all or part of the
molecule.
