  • Patent number: 11423848
    Abstract: A display device comprises a timing controller which provides data comprising a pre-emphasis value and an image data value, and a data driver which supplies to data lines a pre-emphasis voltage generated based on the pre-emphasis value during a first period of a horizontal period, and supplies to the data lines a data voltage generated based on the image data value during a second period of the horizontal period. The timing controller provides data based on which the pre-emphasis value is changed in correspondence with one screen mode selected from a plurality of screen modes having different target color coordinates.
