Patent ID: 6924792

Claim:
A display device comprising: a first light-transmissive sheet having an outer surface and an inner surface; a second light-transmissive sheet having an outer surface and an inner surface; wherein one or both of said inner surfaces of said light-transmissive sheets are hydrophobic; one or more measures of a light-transmissive liquid; a sealed space between the inner surface of the first sheet and the inner surface of the second sheet, the liquid being enclosed within said sealed space; a plurality of multi-colored light filters comprising a plurality of differently-colored elements being associated with each measure of liquid; a plurality of electrical elements, located adjacent to, but electrically insulated from, each liquid measure associated therewith; a power supply; and a microprocessor or other suitable means coupled to the power supply and the electrical elements, capable of selectively controlling the electrical potential delivered to each of said electrical elements so as to create an electric field affecting the associated measure of liquid, thereby inducing a change in the location or shape of said affected liquid measures, and thereby refracting and modulating the direction of light passing through said liquid measures to be directed onto or through selected colored areas of said multi-colored light filters.
