ABSTRACT:
Electroluminescent information display panels are disclosed suitable for uses extending from simple numeric displays to color TV panels. The new panel consists of an unpatterned layer of electroluminescent powder particles of thickness equal to that of one particle embedded in a high-dielectric resin with a transparent front electrode and a black back electrode to increase visual contrast. The operating voltage is low enough to permit use of common transistors for addressing the lighting segments of the display and a new resonant circuit is provided for this purpose. The new electrode pattern is deposited on the black back layer of the panel and the electrical circuits are placed on a second rear substrate and connected to the front plate. The electrical circuits may consist of coextensive matrices of interconnected thin-film transistors driven from the side by shift registers and line storage registers.
