description A display device includes a sensing circuit and a controller which selects a pixel row in a frame period. A vertical blank period of the frame 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 a 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 calculates a threshold voltage parameter and a mobility parameter based on the first and second source voltages, predicts a saturated source voltage of the driving transistor based on the threshold voltage parameter and the mobility parameter, and calculates a threshold voltage of the driving transistor based on the saturated source voltage.
