  • Patent number: 8269230
    Abstract: A multilayer-doped OLED structure comprises a substrate, an anode layer, a hole transport layer, a multilayer-doped organic light emitting layer, an electron transport layer, an electron injection layer and a metallic cathode layer. The multilayer-doped organic light emitting layer functions as a lighting source. The multilayer-doped organic light emitting layer is fabricated by a plurality of film deposition and doping processes. Thereby, the multilayer-doped organic light emitting layer has better quantum effect to improve luminous efficiency and illumination of OLED.
