Abstract: A source-driving circuit comprises a plurality of first and second data-outputting units, a first and a second charge-sharing units and a charge-sharing switch circuit. The first and second data-outputting units have corresponding first and second output terminals respectively for outputting data signals with a first polarity and a second polarity. The first and second charge-sharing units comprise a plurality of first and second switches respectively. Each first switch is electrically connected between each two first output terminals and each two second output terminals. Each second switch is electrically connected between one of the first outputting terminals and a corresponding one of the second outputting terminals. A charge-sharing switch circuit is electrically connected to the first and second charge-sharing units for outputting a switch signal to the first and second charge-sharing units according to a polarity signal, so as to determine the on/off statuses of the first and second switches.
