Claim 12:
13. A method of controlling a source driver, the source driver having a plurality of driving channels, each having a charge sharing circuit and the charge sharing circuit comprising a first control switch and a second control switch, the method comprising:
controlling each of the plurality of driving channels to be coupled to an output terminal among a plurality of output terminals, to output data voltages to the corresponding output terminal in a driving phase of a display line period; and
determining whether to couple each of the plurality of driving channels to a charge sharing bus in a charging phase of the display line period;
wherein the step of determining whether to couple each of the plurality of driving channels to the charge sharing bus comprises:
turning on the first control switch to couple the driving channel to the charge sharing bus while keeping the second control switch off when a next data voltage to be output to the corresponding output terminal is greater than a current data voltage on the corresponding output terminal; and
turning on the second control switch to couple the driving channel to the charge sharing bus while keeping the first control switch off when the next data voltage to be output to the corresponding output terminal is smaller than the current data voltage on the corresponding output terminal.
