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.
