Gate driver, display apparatus having the same and method of driving display panel using the same

Gate drive section includes a pre-charging signal generator and the signal summation. The precharge signal generation unit generates the precharge signal which changes according to the current data signal corresponding to the previous data signal and the current gate lines corresponding to the previous gate line. The signal summation unit generates a gate signal by summing the pre-charge signals and the pre-charging signal. Accordingly, to prevent occurrence of ghost due to the pre-charge driving is possible to improve the display quality of the display panel.
