Abstract
A source driver includes a plurality of first data channel pairs, a plurality of second data channel pairs, a first switch group, a second switch group, a third switch group, and a fourth switch group. Each of the first data channel pairs includes a first odd channel and a first even channel. The channels outputting voltages having the same polarity are short circuited together through the switch groups during a charge sharing period. As a result, the swings of the voltages of data lines coupled the corresponding channel are reduced, and further power consumption in the source driver could be reduced as compared with the related art.
