DEVICE AND METHOD FOR DRIVING DISPLAY PANEL

摘要

PURPOSE: A device and method for driving a display panel are provided to reduce the area and power consumption of a device by commonly using a pulse signal generator at all channel respectively. CONSTITUTION: In a device and method for driving a display panel, a time variation signal generating unit(410) generates a time variation signal. A common pulse signal generator(430) generates a plurality of pulse signals. A selection unit(420) selects a gradation voltage corresponding video data. A buffer part(440) buffers the output of the selection unit. The selection unit and the buffer unit are arranged in the channels respectively. A time variation signal and a pulse signal are commonly inputted to the selection unit of each channel.
