  • Electroluminescent devices
    Patent number: 6777884
    Abstract: An electroluminescent lamp or display comprises a first electrode on a substrate interdigitated with a second electrode on the same substrate. A layer of electroluminescent material is provided over the electrodes. The arrangement has the advantage that light from the electroluminescent material does not need to pass through either of the electrodes. The substrate may be a printed circuit board. In an alternative embodiment the second electrode is provided over the layer of electroluminescent material and gaps are provided in the electrode for the emission for light. The electroluminescent lamps may be used to form a seven-segment display.
