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.

Abstract: A display device includes a plurality of pixels, a power supply, a voltmeter, and a timing controller. The power supply is configured to generate an initialization voltage to be supplied to a sensing pixel among the pixels. The voltmeter is configured to measure a first value of the initialization voltage supplied to the sensing pixel during an active period of a frame period and a second value of the initialization voltage supplied to the sensing pixel during a vertical blank period of the frame period. The timing controller is configured to generate rewrite image data that is supplied to the sensing pixel during the vertical blank period. The rewrite image data is generated from image data applied to the pixels during the active period and a difference between the first and second values.
