Display device

A display device comprising:

• a display panel including a plurality of pixels;
• and
• a display panel driver which determines a number of pixels which display a grayscale value of input image data less than or equal to a first reference grayscale value, determines an operation mode based on the number of the pixels which display the grayscale value of the input image data less than or equal to the first reference grayscale value and a temperature of the display panel 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.

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 the average image load, a temperature of the display panel, and a deterioration degree of pixels 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.
