Claim 0:
1. A display driver for driving a display panel, the display driver comprising: a data driver coupled to a data line of the display panel; a sensing circuit coupled to a sensing line of the display panel; and a controller which controls 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 a pixel included in the display panel 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.
