  • Organic electroluminescent device with improved hole injecting structure
    Patent number: 6351067
    Abstract: An organic electroluminescent device (OELD) with improved luminescent efficiency has been fabricated upon inclusion of an inorganic buffer layer in the hole injecting or electron injecting regions. The structure of the device can be as follows (from bottom to top): ITO\buffer layer\NPB\Alq\Mg:Ag. In comparison with devices without the buffer layer, the present OELD may be more efficient in a proper bias condition.
    Type: Grant
    Filed: January 21, 1999
    Date of Patent: February 26, 2002
    Assignee: City University of Hong Kong
    Inventors: Shuit-Tong Lee, Zhen-Bo Deng, William Alexander Gambling
