Abstract: A source driver includes a plurality of output terminals and a plurality of driving channels. Each of the plurality of driving channels is coupled to an output terminal among the plurality of output terminals and includes an output buffer, an output enable switch and a charge sharing circuit. The output enable switch is coupled between the output buffer and the corresponding output terminal. The charge sharing circuit is coupled to the corresponding output terminal. Wherein, the charge sharing circuits of at least two of the plurality of driving channels are commonly coupled to a charge sharing bus.
