Abstract:
The present invention provides a display device with reduced power consumption and that reduces changes in luminance, and perceptibility of flicker, and a driving method thereof. A display device according to an exemplary embodiment comprises: a display panel configured to display a still image and a motion picture; a signal controller configured to control signals for driving the display panel; and a graphics processing unit configured to transmit input image data to the signal controller, wherein the signal controller comprises a frame memory configured to store the input image data, and the display panel is driven at a first frequency when the motion picture is displayed and the display panel is driven at a second frequency that is lower than the first frequency when the still image is displayed.
