Abstract

This invention provides a color passive matrix bistable liquid crystal display system, in which one respective scan line corresponds to sub-pixels of same color and neighboring scan lines correspond to sub-pixels of different colors. The scan lines are grouped in accordance with the colors of the sub-pixels corresponding thereto such that different scan driving voltages can be provided to the sub-pixels of different colors when the scan lines are scanned. By way of the arrangement of the sub-pixels, different scan driving voltages are switched to the respective scan lines in accordance with the colors of the sub-pixels corresponding thereto. As a result, a demand that the sub-pixels of different colors require different scan driving voltages is satisfied. The image quality is improved.
