Driving device, display apparatus having the same and method of driving the display apparatus

In the driving apparatus, a drive method of a display apparatus and a display apparatus having the same, the signal controller outputs the impulsive data having different gray levels in the frame period in which the display frame period and the video displayed is a still image. Data driver converts the data into the impulsive impulsive voltage. According to the driving method of the driving device, a display device and a display device having the same, the gray level of the impulsive data is applied differentially depending on the image type. Thus, while improving the luminance can be improved dragging phenomenon of the video.
