Abstract: A display panel driving apparatus includes a data driving part, a comparing part, a data signal controlling part, and a gate driving part. The data driving part generates a dummy data signal in response to dummy image data, outputs the dummy data signal to a dummy data line of a display panel, generates a data signal in response to image data, and outputs the data signal to a data line of the display panel. The comparing part outputs a comparison signal in response to the dummy data signal and a delayed dummy data signal generated due to a load of the dummy data line. The comparison signal indicates how much the delayed dummy data signal is delayed with respect to the dummy data signal. The data signal controlling part controls the data signal using the comparison signal.

Abstract: 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.
