1. A display device comprising:
a pixel part including a plurality of pixels, wherein the pixel part is partitioned into a plurality of blocks;
a scale factor provider which calculates a first load value of input image data corresponding to all of the blocks of the pixel part, calculates a second load value of the input image data for each of the blocks, and generates a scale factor based on the first load value and the second load value; and
a timing controller which generates image data by scaling gray values of the input image data based on the scale factor,
wherein when the first load value is less than a reference load value, a luminance of an image displayed in a reference block which has a greatest second load value among the blocks is higher than a luminance of an image displayed in a neighboring block.
