Drive method for an electrophoretic display device and an electrophoretic display device

A drive method for an electrophoretic display device that has an electrophoretic device composed of a suspension fluid containing electrophoretic particles disposed between a common electrode and a plurality of pixel electrodes, a driver that drives the electrophoretic device by applying voltage between the common electrode and the plural pixel electrodes, and a controller that controls the driver. The control method has a display redrawing process that changes the displayed image by applying a common electrode drive pulse that repeats two different potentials to the common electrode, and applying either of the two different potentials to the pixel electrodes according to the updated display content. The display redrawing process includes a first pulse application step that applies a first pulse train to the common electrode as the common electrode drive pulse train, and a second pulse application step that executes after the first pulse application step to apply a second pulse train to the common electrode as the common electrode drive pulse train, the pulses of the second pulse train being wider than the pulses of the first pulse train.
