Abstract
A display apparatus includes a display panel including a pixel to display an image based on input image data, a driving controller which determines a driving frequency of a first display area of the display panel to be a first driving frequency and determines a driving frequency of a second display area of the display panel to be a second driving frequency less than the first driving frequency when the first display area displays a moving image and the second display area of the display panel displays a still image, and an emission driver which outputs a moving image emission signal corresponding to the first driving frequency and a still image emission signal corresponding to the second driving frequency to the display panel. A width of a non-emission period of the still image emission signal is greater than a width of a non-emission period of the moving image emission signal.
