ABSTRACT:
A molded plastic faceplate and/or a molded plastic backplate are used to form a flat panel display. A faceplate mold is formed by laser etching pixel recesses in the mold. The detail of such pixel recesses is copied onto a plastic faceplate by injection molding or compression molding a clear plastic. Such molding achieves pixel detail and depth detail to a microscopic precision. The borders of the pixel areas serve as spacers which separate the faceplate and backplate while containing liquid crystal or phosphor material. Electrical circuits are formed on the faceplate and/or backplate to define control circuitry for display pixels.
