Patent ID: 6927765

Claim:
A method for driving a liquid crystal display having a plurality of scan electrodes and a plurality of data electrodes having a memory effect, said method comprising the steps of: (a) addressing a plurality of said scan electrodes and a plurality of said data electrodes to reset an area of said liquid crystal display defined by the plurality of scan electrodes and the plurality of data electrodes; (b) addressing at least some of said plurality of scan electrodes sequentially; (c) addressing selected ones of said data electrodes synchronizing with the sequential addressing of the scan electrodes in the step (b) to form an image; and (d) improving a contrast of said image by repeating the steps (b) and (c) a plurality of times without interposing the step (a), wherein repeating the steps (b) and (c) comprises repeating the steps (b) and (c) as long as image data upon which said image is based remains unchanged and a predetermined number of repetitions have not occurred.
