Abstract
A display includes a graphic layer having indicia. A opaque mask layer beneath the graphic layer has light-transmissive areas in registration with selected indicia on the graphic layer. A circuit panel bears light emitters. A spacer layer having openings therein is disposed between the mask layer and the circuit panel, and each light emitter is disposed in an opening of the spacer layer, so that light from each emitter can reach a light-transmissive area of the mask layer overlying the opening housing that light emitter. A control circuit selectively illuminates the light emitters so as to selectively illuminate indicia on the graphic layer through the light-transmissive areas. The light emitters need not be precisely aligned with the indicia on the graphic layer, such that numerous different displays can be made using identical circuit panels.
