Claim 21:
22. A display device comprising: a display panel including a data line, a sensing line, and a pixel coupled to the data line and the sensing line; a scan driver which provides a scan signal and a sensing signal to the pixel; a data driver coupled to the data line; a sensing circuit coupled to the sensing line; and a controller which controls the scan driver, the data driver and the sensing circuit, wherein a vertical blank period of a frame period includes a sensing time, wherein the sensing circuit measures a first source voltage of a driving transistor of the pixel at a first time point of the sensing time, and measures a second source voltage of the driving transistor at a second time point of the sensing time, and wherein the controller corrects input image data for the pixel based on a predicted saturated source voltage of the driving transistor corresponding to the first and second source voltages.
