Sequential full color display and photocell device

摘要

A full color display and photocell device ( 100 ) includes a fast response liquid crystal display ( 105 ) that has a rate of at least 75 monochrome frames per second, a transparent panel light ( 140 ) behind the fast response LCD that can emit a monochromatic light beam having a selected one of three colors, and a photovoltaic cell ( 150 ) behind the transparent panel light that converts light energy emanating from the transparent panel light into electrical energy. The full color display and photocell device ( 100 ) may also include a controller ( 160 ) that synchronizes information coupled to the fast response LCD and controls the transparent panel light to emit a sequence of monochromatic light beams of three colors.
