Abstract: A display device includes a display panel, a scan driver, a data driver, a sensing circuit, and a controller configured to select a pixel row from a plurality of pixel rows in a vertical blank period of each frame period. The vertical blank period includes a sensing time in which the sensing circuit performs a sensing operation for the selected pixel row. The sensing circuit measures a first source voltage of a driving transistor of each pixel in the selected pixel row 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. The controller predicts a current saturated source voltage of the driving transistor based on the first and second source voltages, and determines a threshold voltage change amount of the driving transistor based on a difference between a previous saturated source voltage and the current saturated source voltage.
