Patent ID: 7701436

Claim:
A method for driving an electrophoretic device, including: an electrophoretic element, in which a dispersal system that includes electrophoretic particles is laid between a common electrode and a pixel electrode; a driving circuit for driving the electrophoretic element by applying a voltage between the common electrode and the pixel electrode; and a controller for controlling the driving circuit; the method comprising: an image rewrite period process for controlling the driving circuit by the controller, and applying a voltage on the common electrode and the pixel electrode, thereby conducting an image rewrite, the image rewrite period process including a reset period and an image signal import period that follows the reset period; wherein the reset period includes: a first reset period process, during which a first voltage is applied between the common electrode and the pixel electrode, thereby causing the electrophoretic particles to migrate; and a second reset period process, during which a second voltage is applied between the common electrode and the pixel electrode, the second voltage having an opposite polarity to the first voltage, thereby causing the electrophoretic particles to migrate, wherein an absolute value of the second voltage is less than an absolute value of the first voltage.
