Abstract
A display device includes: a timing controller to provide data including a pre-emphasis value and an image data value; a gamma reference voltage supplier to selectively supply one of a first gamma reference voltage and a second gamma reference voltage different from the first gamma reference voltage; and a data driver to supply a pre-emphasis voltage, that is generated based on the pre-emphasis value and the first gamma reference voltage, to data lines during a first period of a horizontal period, and to supply a data voltage, that is generated based on the image data value and the second gamma reference voltage, to the data lines during a second period of the horizontal period. The timing controller is to control the gamma reference voltage supplier to supply the first gamma reference voltage during the first period and to supply the second gamma reference voltage during the second period.
