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.

Abstract: A display device includes a pixel and a sensing channel connected to the pixel through a sensing line. The pixel includes: a first transistor including a gate electrode connected to a first node, a first electrode connected to a first power line, and a second electrode connected to a second node; a second transistor including a gate electrode connected to a first scan line, a first electrode connected to a data line, and a second electrode connected to the first node; a third transistor including a gate electrode connected to a second scan line, a first electrode connected to the second node, and a second electrode connected to a third node; and a fourth transistor including a first electrode connected to the first power line and a second electrode connected to the third node. The sensing line is connected to the third node.
