Source driving circuit and operating method thereof

A source driving circuit, adapted to a display panel, the source driving circuit comprising:

• a data channel, configured to be coupled to a data line of the display panel and drive the data line of the display panel sequentially according to a first display data and a second display data, wherein the first display data corresponds to a first scan line of the display panel, and the second display data corresponds to a second scan line of the display panel next to the first scan line of the display panel,
• wherein the data channel comprises:
• an amplifier, configured to sequentially output a first driving voltage indicated by the first display data and a second driving voltage indicated by the second display data;
• and
• a switch, configured to be coupled between the amplifier and the output terminal of the data channel to be turned on or off according to a switch control signal;
• and
• a control circuit, coupled to the data channel,
• wherein the control circuit comprises:
• a multiplexer, configured to select one of a first data output control signal and a second data output control signal as the switch control signal according to the similarity between the second display data and the first display data and delay a time point that the data channel outputs the second display data by using the switch control signal to delay a starting point of an on-state of the switch for a delay time.
