Embodiments of the disclosure relate to a control circuit, a display device, and a method for driving a main processor. Specifically, there may be provided a control circuit, a display device, and a method for driving a main processor which may reduce power consumption in the transmission/reception circuit connected with the interface by powering off at least one of the source transmission/reception circuit or sink transmission/reception circuit electrically connected with the auxiliary channel AUX during at least a partial period of the vertical blank period.

Control circuit, display device, and method for driving main processor

Embodiments of the disclosure relate to a display device and a data driving circuit. The display device comprises a display panel including a plurality of subpixels and a plurality of data lines electrically connected with the plurality of subpixels and a data driving circuit outputting a data voltage to the plurality of data lines, wherein the data driving circuit outputs the data voltage for image display to the plurality of data lines during an active period and outputs a step voltage to stepwise decrease a level of the data voltage to a preset target voltage level or stepwise increase the level of the data voltage from the target voltage level during a blank period different from the active period. Specifically, there may be provided a display device and a data driving circuit capable of enhancing display quality in a dark mura area and a bright mura area by outputting a step voltage to stepwise decrease the level of a data voltage to a preset target voltage level or stepwise increase the level of the data voltage from the target voltage level during a blank period.
