1. A display device comprising:
a display panel including pixels; and
a driver to drive the display panel based on input image data, to selectively perform a sensing operation for the pixels by comparing grayscale values of the input image data and a reference grayscale value, to selectively perform a luminance control operation for controlling luminance of the display panel in response to a luminance control signal, and to adjust the reference grayscale value when the luminance control operation is performed,
wherein the driver is configured to generate a histogram of the grayscale values of the input image data, and to compare the grayscale values of the input image data and the reference grayscale value based on the histogram.
