Patent ID: 8085241

Claim:
A method of driving an electrophoretic display device including a plurality of scanning lines, at least one signal line that crosses the plurality of the scanning lines, an opposite electrode, and a pixel that corresponds to an intersection between one of the plurality of the scanning lines and the signal line, the pixel including: a pixel electrode facing the opposite electrode; a switching transistor connected to the signal line, the scanning line, and the pixel electrode; an electrophoretic element disposed between the pixel electrode and the opposite electrode, the electrophoretic element having a plurality of electrically charged micro-particles dispersed in dispersion media; and a condenser connected to the pixel electrode, the method comprising: forming a complete display image in an image forming period, the image forming period including L frame periods (L being an integer greater than two), wherein each of the plurality of scanning lines are selected in each of the L frame periods, wherein the L frame periods include a first frame period and a second frame period successively following the first frame period; and providing the pixel with an image signal and storing the image signal in the condenser in each of the first and second frame periods when the scanning line corresponding to the pixel is selected, wherein the image signal provided in the first frame period and the image signal provided in the second frame period are equal to each other in width and electric potential.
