Abstract:
1. A colorful passive matrix bistable liquid crystal display system, comprising: a plurality of data electrodes aligned in parallel; a plurality of scan electrodes aligned in parallel, wherein said scan electrodes are perpendicular to said data electrodes and both overlap each other, an intersection area of each said scan electrode and each said data electrode defines a sub-pixel, and each said scan electrode corresponds to a plurality of said sub-pixels of same color and said neighboring scan electrodes respectively correspond to said sub-pixels of different colors, said sub-pixels of different colors are constituted by red bistable liquid crystals, green bistable liquid crystals and blue bistable liquid crystals, wherein said red bistable liquid crystals, said green bistable liquid crystals and said blue bistable liquid crystals have the same cell size; a pixel scan line driver electrically connecting with said scan electrodes and providing the same scan driving voltage to the sub-pixels of same color and different scan driving voltages to the sub-pixels of different color in accordance with the illuminating colors of said sub-pixels corresponding thereto, wherein the sub-pixels of red color have a lowest scan driving voltage and the sub-pixels of blue color have a largest scan driving voltage; a data line driver electrically connecting with said data electrodes to provide data voltages to said data electrodes; and a timing controller for controlling said pixel scan line driver and said data line driver to transmit the respective scan driving voltages and data voltages.
