1. A display device comprising:
a display unit including pixels coupled to scan lines, sensing scan lines, data lines, and sensing lines;
a scan driver which supplies a scan signal to the scan lines, and supplies a sensing scan signal to the sensing scan lines;
a data driver which supplies an image data voltage to the data lines;
a sensing circuit which detects sensing values of the pixels on a pixel column basis through the sensing lines during a sensing period, and
a timing controller which transmits image data in which a clock is embedded to the data driver,
wherein the sensing circuit comprises:
an analog-to-digital converter which converts the detected sensing values into digital data during the sensing period and outputs sensing data;
a clock recovery circuit which extracts the clock from the image data;
a clock generator which sequentially outputs a plurality of sensing clocks by dividing the clock extracted from the image data; and
an output circuit electrically coupled to the sensing lines and providing the sensing values to the analog-to-digital converter on the pixel column basis
wherein the analog-to-digital converter pauses the detection of the sensing values during a first period of the sensing period.
