Claim 11:
12. A method of driving a display panel, the method comprising:
determining a boundary between a first display area of the display panel and a second display area of the display panel based on input image data;
determining a driving frequency of the first display area of the display panel to be a first driving frequency and determining a driving frequency of the 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 displays a still image;
outputting a gate signal to a gate line of the display panel;
outputting a data voltage to a data line of the display panel;
generating a moving image emission signal corresponding to the first driving frequency and a still image emission signal corresponding to the second driving frequency; and
outputting the moving image emission signal and the still image emission signal to an emission line of 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.
