Abstract
A display device includes a display panel which operates in a sensing mode or an emission mode, and a data driver electrically connected to the display panel. The display panel includes a first pixel, a second pixel, a third pixel, a fourth pixel, a fifth pixel, a sixth pixel, a first scan line, a second scan line, a first data line, the second pixel. The data driver includes a first switch, a second switch, and an analog front end. The sensing mode includes a first period in which a first scan signal is provided to the first scan line and the first switch is turned on, a second period in which the first scan signal is provided to the first scan line and the second switch is turned on, and a third period in which a second scan signal is provided to the second scan line.
