Flexible Organic LEDâ„¢s
Presented By: Ryan Evans
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 LEDâ„¢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 LEDâ„¢s.
The problem of the longevity of the Organic LED has been over come by adding a thin sheet of metal in with it.
