Display panel driving device, display device, and driving method thereof

A display panel driving device for driving a display panel including a data line, a sensing line, and pixels coupled to the data line and the sensing line, the display panel driving device comprising:

• to a timing controller which generates clock embedded data including image data and a clock training signal;
• and
• a data driver which 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,
• wherein, in the second section, the data driver recovers the clock signal while the sensing signal is being received.

A method of driving a display device including a display panel including a data line, a sensing line, and pixels coupled to the data line and the sensing line, the method comprising:

• generating, by a timing controller of the display device, clock embedded data including image data and a clock training signal;
• recovering, by a data driver of the display device, a clock signal, based on the clock training signal of the clock embedded data;
• recovering, by the data driver, the image data from the clock embedded data, based on the clock signal;
• supplying, by the data driver, a data voltage corresponding to the image data to the data line in a first section;
• and
• receiving, by the data driver, a sensing signal from a pixel of the pixels through the sensing line in a second section different from the first section,
• wherein the receiving the sensing signal includes recovering, by the data driver, the clock signal while the sensing signal is being received.
