Patent ID: 8848001

Claim:
A driving method adapted to a bistable display device comprising a pixel array, the pixel array comprising a plurality of first pixels and a plurality of second pixels arranged in a predetermined manner, the driving method comprising: providing the first pixels with a first pixel voltage and providing the second pixels with a second pixel voltage during a first time period, wherein the first pixel voltage is different from the second pixel voltage; providing the first pixels with the second pixel voltage and maintaining the second pixels provided with the second pixel voltage during a second time period following the first time period; initiating the first pixels to display a gray scale image and providing the second pixels with the first pixel voltage during a third time period following the second time period; and providing the first pixels and the second pixels with a common voltage, wherein the common voltage is alternately switched between the first pixel voltage and the second pixel voltage along with the switching of the first through third time periods and is substantially equal to the second pixel voltage during the first time period.
