    Abstract: A display device includes a display panel. The display panel includes a display panel including a data line, a sensing line, and pixels coupled to the data line and the sensing line. A timing controller generates clock embedded data including image data and a clock training signal. A data driver recovers a clock signal, based on the clock training signal of the clock embedded data, recovers the image data of the clock embedded data, based on the clock signal, supplies a data voltage corresponding to the image data to the data line in a first section, and receives a sensing signal from a pixel of the pixels through the sensing line in a second section different from the first section. In the second section, the data driver recovers the clock signal while the sensing signal is being received.
