  • Non-degenerate wide bandgap semiconductors as injection layers and/or contact electrodes for organic electroluminescent devices
    Patent number: 6433355
    Abstract: An organic light emitting device is provided having a substrate (60), an anode contact electrode (64), a cathode contact electrode (61), and an organic region (62, 63) in which electroluminescence takes place if a voltage is applied between the anode (64) and cathode (61). At least one of the electrodes (61, 64) comprises a non-degenerate wide bandgap semiconductor.

  • Monolithic array of light emitting diodes for the generation of light at multiple wavelengths and its use for multicolor display applications
    Patent number: 5952680
    Abstract: An array of light emitting diodes (LEDs) for the generation of light at multiple wavelengths. The LEDs are realized in a layered structure of semiconductor films grown on one substrate, said array comprising conducting portions for applying a bias to said LEDs and insulating portions, wherein at least one of the insulating or conducting portions is formed by a lateral variation of doping conditions of the top layer of the structure.
