Claim 0:
1. A display device comprising:
a display panel including a plurality of pixels; and
an image data corrector generating corrected image data by adjusting the image data,
wherein the image data corrector divides the display panel into a plurality of unit areas, and adjust the image data for a unit area among the plurality of unit areas by using a full image load for the entire display panel, a first image load for the unit area, and a second image load for peripheral unit areas surrounding the unit area among the plurality of unit areas, and
wherein the image data corrector includes:
a full image load calculator calculating the full image load by dividing a current display panel luminance corresponding to the image data for the entire display panel by a maximum luminance corresponding to the image data for the entire display panel;
a first image load calculator calculating the first image load by dividing a current unit area luminance corresponding to an image data for the unit area by a maximum luminance corresponding to the image data for the unit area; and
a second image load calculator calculating the second image load by dividing a current peripheral unit area luminance corresponding to an image data for the peripheral unit areas by a maximum luminance corresponding to the image data for the peripheral unit.
