Abstract: A display driving circuit in accordance with the inventive concepts may include a source amplifier. The source amplifier may include an output transistor configured to amplify an input signal to generate an output signal, and charge a source line of a display panel using the output signal. The source amplifier may include an output transistor switch configured to control the output transistor, and a switch control block configured to receive configuration bits including on/off time information of the output transistor switch to generate a switch control signal. The on/off time information includes information for turning on the output transistor switch in synchronization with a horizontal synchronous signal associated with the display panel, and information for turning off the output transistor switch at a time when the source line of the display panel is charged to a desired charge level.

Abstract: A display device includes a display panel having pixels arranged at intersections of source lines and gate lines, a plurality of source drivers configured to dispersedly output image data signals to the source lines in response to source control signals and a data packet, a plurality of gate drivers configured to drive gate lines in response to gate control signals so as to be connected with pixels corresponding to the source lines, and a timing controller configured to output the data packet, the source control signals, and the gate control signals. At least one of the plurality of source drivers is configured to output carry information associated with an output of the image data signals, and at least another of the plurality of source drivers is configured to output the image data signals in response to the carry information.
