ABSTRACT:
An electroluminescent lamp has a luminescent layer placed between a rear electrode layer and a top electrode layer, which is at least partially transparent to light. The electrodes are arranged to excite the luminescent layer by applying a potential to the layer. An insulating layer is placed between the rear electrode layer and the luminescent layer, to increase the capacitance of the lamp. At least one of the layers includes a terpolymer, e.g., vinylidene fluoride-tetrafluoroethylene-hexafluoropropylene. In some applications (e.g., in wristwatches), the luminescent layer includes phosphor, the insulating layer includes barium titanate, and the rear electrode includes silver, all distributed through the terpolymer. In other applications (e.g., in cellular phones or pagers), the rear electrode includes carbon.
