Abstract: A source driving circuit includes a first source driver and a second source driver. The first source driver is configured to convert latched first image data into a plurality of first data voltages in response to a first triggering moment of a first data transmission control signal, and output the plurality of first data voltages based on a second triggering moment of the first data transmission control signal. The second source driver is configured to convert latched second image data into a plurality of second data voltages in response to a first triggering moment of a second data transmission control signal, and output the plurality of second data voltages based on a second triggering moment of the second data transmission control signal. The second triggering moment of the first data transmission control signal and the second triggering moment of the second data transmission control signal have a time difference.
