Claim 0:
1. A display apparatus comprising:
a display panel comprising a gate line, a data line and a pixel, and configure to display an image based on input image data;
a gate driver configured to output a gate signal to the gate line;
a data driver configured to output a data voltage to the data line;
a driving controller configured to drive display areas of the display panel in different driving frequencies; and
a power voltage generator configured to output a data power voltage to the data driver,
wherein the display panel includes a first display area displaying a moving image and a second display area displaying 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 comprises a driving frequency determiner determines 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.
