Abstract

A cholesteric liquid crystal display comprising red, green, and blue cholesteric liquid crystal modules. It further comprises a first thin-film photovoltaic module disposed between the blue and the green cholesteric liquid crystal modules, and a second thin-film photovoltaic module disposed between the green and the first selective light reflection modules. The first thin-film photovoltaic module is partially photo-permeable in which the transmittance of blue light is lower than the transmittance of the other lights. It IS preferably a dye sensitized solar cell module which specifically responsible for harvesting blue light. The second thin-film photovoltaic module is partially photo-permeable in which the transmittance of green light is lower than the transmittance of the other lights. It is preferably a dye sensitized solar cell module which specifically responsible for harvesting green light.
