What the Flexible Organic Light Emitting Diode
Consist of
The Top Layer is the Cathode layer made of
tungsten releases electrons when current is run
through it. Emissive Layer removes electrons
from the cathode layer to make light. Conductive
layer is made from a type of organic plastic that
removes the electron wholes Then the Anode Layer
that consist of removing and adding electron
holes while the current is running through it and
is made from graphite particles Followed by the
Substrate layer is used to support the Organic
LED and is made up of glass, clear plastic

Some Advantages of Using Organic LEDs
The Flexible Organic LED is easily mass produced
because of its unique ability to be printed out
on Ink Jet printers and sometimes Screen Printing
Technologies. The enable people to see a wide
ranged of colors and sit from almost any angle
without degrading the picture quality even at 90
degree angles. It also has the unique ability to
use less energy because of how its made up and
has better response time than other LEDs. The
problem of the longevity of the Organic LED has
been over come by adding a thin sheet of metal in
with it.
