Classification: CPC G | IPC G

Claim 11:
12. A method of driving a display panel, the method comprising:
independently determining driving frequencies of display areas by a driving controller;
generating a data power voltage; and
outputting a data voltage to a data line of the display panel using input image data, and the data power voltage,
wherein the display panel includes a first display area representing a moving image and a second display area representing a static image,
wherein, in a first frame, the data power voltage has a high power voltage level in a first time period corresponding to the first display area and in a second time period corresponding to the second display area,
wherein, in a second frame, the data power voltage having the high power voltage level in a third time period corresponding to the first display area and a low power voltage level in at least a portion of a fourth time period corresponding to the second display area,
wherein the driving controller includes a driving frequency determiner determines the driving frequencies of the display areas based on flicker values according to grayscale values of the input image data corresponding to the display areas, and
wherein the driving frequency determiner increases a driving frequency when a flicker value increases.
