Patent ID: 8493318

Claim:
An apparatus for driving an Electrophoretic Display (EPD), the apparatus comprising: a controller for controlling an overall operation of the apparatus for driving the EPD, determining data to be displayed on the EPD, and outputting a drive signal; a driver for generating a driving voltage pulse for moving black particles and white particles to display the data on the EPD according to the drive signal output from the controller, thereby controlling the EPD; and the EPD for displaying a representation of the data in white or black according to the driving voltage pulse, wherein the driver generates the driving voltage pulse for moving the black particles or the white particles in such a manner that the driving pulse is divided into a predetermined number of subpulses, and an idle period during which a voltage is not applied intervenes between the respective divided subpulses, and wherein the driver generates the driving voltage pulse in such a manner that the driving voltage pulse for moving the white particles to display the data in white is divided into two subpulses with the same duration which is equal to a half of a duration of the driving voltage pulse for moving the black particles to display the data in black, and an idle period intervenes between the divided subpulses.
