1. A display device comprising:
a display panel including a plurality of pixels; and
a display panel driver which determines an average image load of input image data, determines an operation mode based on a grayscale value of the input image data and the average image load as a first operation mode or a second operation mode, applies a first scale factor to the input image data in the first operation mode, applies a second scale factor different from the first scale factor to the input image data in the second operation mode, and drives the display panel,
wherein the display panel driver operates as the first operation mode when a number of pixels which display the grayscale value less than or equal to a first reference grayscale value, among the plurality of pixels, is greater than a first reference number and the average image load is less than or equal to a first reference load.
