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 LED’s
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 LED’s.
The problem of the longevity of the Organic LED has been over come by
adding a thin sheet of metal in with it.
Commercial Uses of the Organic LED
