Abstract
A source driver and a common voltage driver for a display device using a time division driving method, in which the source driver outputs an analog voltage corresponding to digital image data to a corresponding source line out of a plurality of source lines, after precharging the corresponding source line with a predetermined voltage. The common voltage driver discretely and sequentially increases or decreases the common voltage. By using the source driver and the common voltage driver, the power consumed upon driving of the display device can be reduced.
