Claim 8:
9. A driving method of a display device which includes a pixel part including a plurality of pixels and is partitioned into a plurality of blocks, the driving method comprising:
calculating a first load value of input image data corresponding to all of the blocks of the pixel part;
calculating second load values of the input image data for each of the blocks;
generating a scale factor based on the first load value and the second load values;
generating image data by scaling gray values of the input image data by using the scale factor, and
generating a data signal corresponding to the image data to supply the data signal to the pixels,
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.
