Abstract
A source driver including a first output buffer, a second output buffer and a plurality of switches is provided. The first output buffer is connected to an output line. The second output buffer is connected to another output line. During a charge-sharing period, the first switch and the fourth switch are not conducted, and the second switch, the third switch, the fifth switch and the sixth switch are conducted. A first node, a second node and the output lines are connected together to perform a charge-sharing operation during the charge-sharing period. Based on the circuit structure of the source driver, the efficiency of the charge-sharing operation is improved and the chip area of the source driver is reduced.
