3. What is an OLED ? OLED - Organic Light Emitting Diode An OLED is an electronic device made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted. A device that is 100 to 500 nanometers thick or about 200 times smaller than a human hair. .

5. Early technology would emmite a short burst of light when a voltage was applied

6. This early form applied high-voltage alternating current field to crystalline thin films of acridine orange and quinacrine.

7. 1960s - AC-driven electroluminescent cells using doped anthracene was developed.

8. In 1987 Chin Tang and Van Slyke introduced the first light emitting diodes from thin organic layers.

11. Anode (transparent) - The anode removes electrons (adds electron "holes") when a current flows through the device.

12. Organic layer:

13. Conducting layer - This layer is made of organic plastic molecules that transport "holes" from the anode. One conducting polymer used in OLEDs is polyaniline.

16. The intersections form the pixels

17. Easy to make

18. Use more power

20. Anode over lays a thin film transistor (TFT)

21. Requires less power

22. Higher refresh rates

24. Fig : power efficiency and luminance of oled as a function of current density.

26. Reducing the distance between solar cell and OLED

28. Cell Phone screens

29. Computer Screens

30. Keyboards (Optimus Maximus)

31. Lights

33. First OLED TV sold in stores.

34. 11'' screen, 3mm thin
