Claim 11:
12. 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 temperature of the display panel 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 the temperature of the display panel is lower than or equal to a first reference temperature and the average image load is less than or equal to a first reference load, and
wherein the display panel driver determines a first load scale factor according to the average image load in the first operation mode, determines a first temperature scale factor according to the temperature of the display panel in the first operation mode, determines the first scale factor based on the first load scale factor and the first temperature scale factor, determines a second load scale factor according to the average image load in the second operation mode, determines a second temperature scale factor according to the temperature of the display panel in the second operation mode, and determines the second scale factor based on the second load scale factor and the second temperature scale factor.
