GAPLESS ELECTROLUMINESCENT DISPLAYS.

Abstract

An experimental study of the lamination of electroluminescent (EL) display control electrodes, is described. The study included selection and test of suitable voltage barrier materials, for separation of adjacent or overlapping layers of electrodes. The material finally selected, polymeric 1,4-dimethylbenzene, proved to have very high dielectric strength, coupled with continuous pin-hole free film characteristics when used in very thin film layers. Films of 2 to 2.5 microns thickness proved to be adequate for electrical isolation of adjacent or overlapping electrodes, at 250 volt 400 hertz, with a minimum of voltage drop across the insulating film. Techniques for handling this film were investigated, and gapless bargraph and numeric electroluminescent (EL) displays were fabricated to demonstrate this method's effectiveness of construction.
