Claim 5:
6. The display device of claim 5, wherein the partial luminance controller determines the local scaling factor as a first constant and applies the first constant to the image data for the unit area corresponding to the first image load when the second image load is higher than a preset maximum value, the local scaling factor as a second constant smaller than the first constant, and applies the second constant to the image data for the unit area corresponding to the first image load when the second image load is lower than a preset minimum value, and the local scaling factor as a value between the first constant and the second constant, and applies the second constant to the image data for the unit area corresponding to the first image load when the second image load is between the preset minimum value and the preset maximum value.
