Claim 9:
10. A method of operating a display device which displays an image on a display panel including a plurality of unit areas by adjusting a luminance of an image data, the method comprising:
calculating a full image load for the entire display panel, a first image load for a unit area among the plurality of unit areas, and a second image load for peripheral unit areas surrounding the unit area; and
adjusting the luminance of the image data for the unit area using the full image load, the first image load, and the second image load,
wherein the full image load is a current luminance corresponding to the image data for the entire display panel divided by a maximum luminance corresponding to the image data for the entire display panel, the first image load is a current unit area luminance corresponding to the image data for the unit area divided by a maximum luminance corresponding to the image data for the unit area, and the second image load is a current peripheral unit area luminance corresponding to the image data for the peripheral unit areas divided by a maximum luminance corresponding to the image data for the peripheral unit areas.
