Electrophoretic device, electronic apparatus, and method for driving the electrophoretic device

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 voltage-equivalent of a first gradation, which has a lower level of brightness than an intermediate gradation, 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 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 higher level of brightness than the intermediate gradation, thereby causing the electrophoretic particles to migrate.
