<p>An electroluminescent lamp or display comprises a first electrode (11) on a substrate (12) interdigitated with a second electrode (10) on the same substrate (12). A layer of electroluminescent material (9) is provided over the electrodes (10, 11). The arrangement has the advantage that light (8) from the electroluminescent material does not need to pass through either of the electrodes (10, 11). The substrate (12) may be a printed circuit board. In an alternative embodiment the second electrode is provided over the layer (9) 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.</p> |
