Abstract: The present disclosure relates to a display device and a method of driving the same, and more specifically, to a display device for preventing a user from recognizing a change in luminance when a frame frequency is changed, and a method of driving the same. A display device of the present disclosure includes a display panel including a plurality of pixel regions, a gate driver configured to sequentially supply light emission control signals to horizontal lines of the display panel, a data driver configured to supply a data signal corrected by a source voltage to the display panel, and a dimming controller configured to control whether to gradually change a frame frequency and gamma correction data according to a duty ratio of the light emission control signal.
