Claim Text:
1. A source driver, comprising: a data register unit configured to receive an image data signal and provide a plurality of display data; a plurality of data channels coupled to the data register unit and configured to receive the display data and provide a plurality of pixel voltages according to the display data, the data channels being grouped into a plurality of data groups and each data group corresponding to at least two of the data channels; and a plurality of polarity determining units coupled to the data channels, each of the polarity determining units being configured to: determine preset charging directions of pixel voltages provided by the coupled data channels of a corresponding one of the data groups, according to the received display data of the coupled data channels and the previous display data corresponding to the received display data; determine whether to invert polarities of a part of the pixel voltages provided by the coupled data channels of the corresponding data group, according to the preset charging directions of the pixel voltages of the corresponding data group; and determine whether to enable a charge sharing function according to the preset charging directions of the pixel voltages of the corresponding data groups.
