Organic Light

Organic light emitting diodes is a new display technology, which uses organic thin materials that are placed between conductors. When an electric current is applied, a bright light is emitted. OLEDs are thin, transparent, flexible, foldable displays. In 1987 researchers of Eastman Kodak company invented OLED diode technology. The principal inventors were Chemists Ching W. Tang and Steven Van Slyke. In 2001 they received an Industrial Innovation Award from the American Chemical Society for their contribution in organic light emitting diodes. In 2003, Kodak realised its first OLED display had 512 by 218 pixels, 2.2 inch. Two technologies necessary to make flexible OLEDs were invented by Researchers at Pacific Northwest National Laboratory and the Department of Energy. Many researchers are contributing to improve the OLED technology. In this paper we give a brief of what is OLED, types of OLED, different fabrication methods of OLED, advantages and disadvantages of OLED.
