1. A method for driving a bi-stable chiral nematic liquid crystal display, by which each frame of said liquid crystal display is divided into a first sub-frame, a second sub-frame and a third sub-frame, said method comprising:

  • driving said first sub-frame to activate bi-stable chiral nematic liquid crystal to homeotropic states to eliminate memory information of pixels;

    driving said second sub-frame to write updated information in said pixels; and

    driving said third sub-frame to zero down applied voltages of said pixels such that said bi-stable chiral nematic liquid crystal stays at states corresponding to write in said updated information.
