Abstract:
A liquid crystal display comprising:a) a layer of reflective chiral nematic liquid crystal material; b) first substrate and a spaced apart second substrate, an inner surface of the first substrate and an inner surface of the second substrate bounding said liquid crystal material layer, the first substrate being closer than the second substrate to a viewer of the display, c) a first set of conductive electrodes disposed on the inner surface of the first substrate and a second set of conductive electrodes spaced apart from the first set of electrodes and disposed on the inner surface of the second substrate bounding said liquid crystal material layer; d) display driver circuitry electrically coupled to the first and the second set of conductive electrodes for generating desired voltage differentials between electrodes of the first set of conductive electrodes and electrodes of the second set of conductive electrodes; and e) a solar cell assembly including a solar cell positioned adjacent said second substrate and electrically coupled to the display driver circuitry, the solar cell receiving illumination passing through the first substrate and said liquid crystal material and converting said illumination to electrical energy to supply power to an energy storage device.
