A processor including: an interface circuit to receive first image data and convert the first image data into second image data; a pattern detecting circuit to detect a pattern in the first or second image data; a brightness detecting circuit to detect a panel brightness value, and to detect a ratio of pixels emitting light; and a real-time sensing circuit, wherein when the pattern is not detected, the real-time sensing circuit performs/stops real-time sensing of the pixels based on whether the panel brightness value is within a range and the ratio of pixels emitting light is greater than or equal to a first threshold; and when the pattern is detected, the real-time sensing circuit performs/stops the real-time sensing of the pixels based on whether the panel brightness value is within the range and the ratio of pixels emitting light is greater than or equal to a second threshold.

Processor, display device including the same, and method for driving the same

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.
