Illumination system for nonemissive electronic displays

Abstract

An illumination system for selectively illuminating a nonemissive electronic display comprises display elements in communication with at least one light source. The system comprises an nonemissive electronic display comprising a substrate having a first and a second surface, nonemissive display media having electrically responsive optical properties disposed on the first surface of the substrate, and a light transmissive element adjacent the second surface of the substrate. Light transmitted through the light transmissive element illuminates the display media. The invention also provides a tiled display comprising a plurality of substrates which can be selectively illuminated. The display elements can be tiled to create complex, selectively illuminated, three-dimensional display structures.
