ABSTRACT:
An electroluminescent lamp constructed by screen printing, in succession on a rigid metal plate in the shape of a watch dial, a first of barium titanate, a second layer of phosphor particles in a polymerizable binder, a light transmissive third layer of indium tin oxide, and a conductive peripheral ring of silver epoxy. A transparent dial overlay of Mylar.TM. film with timekeeping indicia fits within the conductive ring. The conductive ring and the substrate serve as the electrodes for the lamp, which illuminates the dial overlay.
