Abstract: A display device includes a display unit, a scan driver, and a data driver. The display unit includes pixels coupled to scan lines, sensing scan lines, data lines, and sensing lines. The scan driver supplies a scan signal to the scan lines, and supplies a sensing scan signal to the sensing scan lines. The data driver supplies an image data voltage to the data lines, and detects sensing values of the pixels on a pixel column basis through the sensing lines during a sensing period. The data driver includes an analog-to-digital converter which converts the detected sensing values into digital data during the sensing period and outputs sensing data. The analog-to-digital converter pauses the detection of the sensing values during a first period of the sensing period.
