1. A source-driving circuit adapted to a display apparatus, the source-driving circuit comprising:

  • a plurality of first data-outputting units, having a plurality of corresponding first output terminals respectively for outputting a plurality of data signals with a first polarity;

    a plurality of second data-outputting units, having a plurality of corresponding second output terminals respectively for outputting a plurality of data signals with a second polarity;

    a first charge-sharing unit, comprising a plurality of first switches, the first switches being divided into two groups, each of the first switches in a first group being electrically connected between two first output terminals, and each of the first switches in a second group being electrically connected between two second output terminals;

    a second charge-sharing unit, comprising a plurality of second switches, each of the second switches being electrically connected between a corresponding one of the first output terminals and a corresponding one of the second output terminals; and

    a charge-sharing switch circuit, electrically connected to the first charge-sharing unit and the second charge-sharing unit, the charge-sharing switch circuit being configured for outputting a switch signal to the first charge-sharing unit and the second charge-sharing unit according to a polarity signal, so as to determine the on/off statuses of the first switches and the second switches,wherein the polarity signal is configured for indicating whether the data signals need switching the polarities thereof.
