Abstract: A display panel driving apparatus is disclosed. In one aspect the apparatus includes a gate driving part and a data driving part. The gate driving part is configured to increase a gate signal applied to a gate line of a display panel from an OFF voltage to a ON voltage, in response to an activation of a gate clock signal. It is also configured to decrease the gate signal from the ON voltage to a kickback compensation voltage between the OFF voltage and the ON voltage through a plurality of steps in response to an activation of a kickback compensation signal. The data driving part is configured to apply a data signal to a data line of the display panel. Therefore, a data-charging rate may be increased, and thus a display quality of the display apparatus may be increased.

Each of the pixels is connected to a corresponding gate line of the gate lines and a corresponding data line of the data lines. The gate driver is configured to drive the gate lines. The data driver is configured to drive each data line of the data lines in response to a corresponding data signal. The timing controller is configured to, in response to an image signal and a control signal, apply the corresponding data signals to the data driver and control the gate driver. Each corresponding data signal reflects a kickback compensation value corresponding to a distance between the gate driver and the corresponding data line in the first direction.
