Patent ID: 8411028

Claim:
An electrophoretic display device driving circuit that drives an electrophoretic display device that includes a display unit having a plurality of pixels, each of the plurality of pixels including: an electrophoretic element, containing electrophoretic particles, that is provided between a pixel electrode and a common electrode that face each other; a pixel switching element; a memory circuit to which an image signal may be written through the pixel switching element; and a switch circuit that controls switching of the pixel electrode in accordance with an output based on the image signal in the memory circuit, the electrophoretic display device driving circuit comprising: a low-speed clock supply unit that supplies a low-speed clock; a high-speed clock supply unit that supplies a high-speed clock having a frequency higher than that of the low-speed clock; and a control unit, the control unit controlling writing of the image signal to the memory circuit on the basis of the high-speed clock when changing images, and controlling supply of a predetermined pixel potential to the pixel electrode through the switching control on the basis of the low-speed clock during a stand-by mode when images are not being changed.
