1. A display apparatus comprising:
a display panel including a pixel, wherein the display panel displays 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,
wherein a width of a non-emission period of the moving image emission signal and a width of a non-emission period of the still image emission signal are controlled by adjusting an emission signal based on a driving frequency such that a luminance of the second display area is substantially the same as a luminance of the first display area.
