Abstract
A composite multi-layered display device consists of two components: a light emitting component which can be used to generate and display images, and a generating component such as a solar cell which generates an electrical current in the presence of light. The two components are incorporated into corresponding co-extensive layers, with the light emitting component being light transmissive to allow external light to impinge on the generating component. Preferably, the light emitting component includes a light emitting polymer material and the generating component includes a solar cell which includes amorphous silicon.
