Display device and a driving apparatus thereof and method driving thereof

And the liquid crystal display device having an effective impulsive driving method is disclosed a driving apparatus thereof, and a driving method. The display panel displays an image. The timing controller outputs a first control signal and second control signal based on the control signal input. Data driver and outputs the normal data signal for the first output abnormal data signal during the first interval on the basis of a control signal to the display panel, and a second region on the display panel. The gate driver outputs a gate signal having a second gate pulse corresponding to a second control signal to the expanded partial section a first gate pulse and the second interval of the first interval on the basis of the display panel. Thus, the sheave improve the filling factor of the normal data voltage when driven by impulse it is possible to further improve the display quality of the video.
