Claim 0:
1. A method of driving a display panel that includes a first display region having a first resolution and a second display region being adjacent to the first display region and having a second resolution higher than the first resolution, the method comprising:
determining a maximum luminance data among first data that are applied to the first display region;
calculating a first candidate compensation gain based on (a) a luminance gain corresponding to a first value obtained by dividing a second reference luminance of the second display region by a first reference luminance of the first display region and (b) a gamma value for the display panel;
calculating a second candidate compensation gain corresponding to a second value obtained by dividing a maximum gray-level for the display panel by a gray-level of the maximum luminance data;
determining a smaller value between the first candidate compensation gain and the second candidate compensation gain as a compensation gain;
generating first compensated data by applying the compensation gain to the first data;
displaying a first image in the first display region based on the first compensated data; and
displaying a second image in the second display region based on second data that are applied to the second display region.
