Classification: CPC G | IPC G

Claim 0:
1. A source driver, comprising:
a plurality of output terminals; and
a plurality of driving channels, each coupled to an output terminal among the plurality of output terminals and comprising:
an output buffer;
an output enable switch, coupled between the output buffer and the corresponding output terminal;
a charge sharing circuit, coupled to the corresponding output terminal; and
a charge sharing switch, coupled to the charge sharing circuit, configured to enable or disable the charge sharing circuit;

wherein the charge sharing circuits of at least two of the plurality of driving channels are commonly coupled to a charge sharing bus; and
wherein each of the plurality of driving channels further comprises:
a data calibration circuit, coupled to the charge sharing circuit, configured to generate a first voltage greater than a data voltage with a first voltage shift according to the data voltage and output the first voltage to the charge sharing circuit, or generate a second voltage smaller than the data voltage with a second voltage shift according to the data voltage and output the second voltage to the charge sharing circuit,
wherein the data voltage is a voltage to be output to the corresponding output terminal.
