Abstract:
There is provided a method for driving an electrophoresis display device equipped with a plurality of pixel electrodes, each of the pixel electrode being provided for every pixel, a common electrode provided to oppose the plurality of pixel electrodes, and an electrophoresis element containing electrophoresis particles, the electrophoresis element being sandwiched by the plurality of pixel electrodes and the common electrode. The method includes driving the electrophoresis element and updating a display by a common voltage swing drive method in which a rectangular wave in which a first potential and a second potential are repeated is applied to the common electrode for not less than one cycle during a display update time in which the first potential or the second potential for moving the electrophoresis particles is applied to each of the pixel electrodes. A frequency of the rectangular wave is not less than 20 Hz.
