Abstract:
A method for driving an electrophoretic device that includes an electrophoretic element between a common electrode and a pixel electrode, the electrophoretic element including electrophoretic particles, the method including applying voltages on the common electrode and the pixel electrode, thereby conducting an image rewrite process, wherein the image rewrite process includes a first reset period process, during which a voltage-equivalent of a first gradation, which has a higher level of brightness than an intermediate gradation, is applied between the common electrode and the pixel electrode, thereby causing electrophoretic particles to migrate; and a second reset period process, during which a voltage-equivalent of a third gradation which is between a second gradation and the first gradation is applied between the common electrode and the pixel electrode, the second gradation being at a lower level of brightness than the intermediate gradation, thereby causing the electrophoretic particles to migrate.
