摘要:
A driving apparatus of a liquid crystal display device according to an embodiment of the present invention includes a liquid crystal display panel having a liquid crystal cell of a matrix shape to display a video signal; N (where N is a positive integer) number of data drive circuits that generate a polarity pattern of the video signal and supply it to the liquid crystal cell through a plurality of output channels; and a polarity controller that controls the polarity signal and supplies it to the N number of the data drive circuits on the basis of a first selection signal corresponding to the number of the output channels and a second selection signal corresponding to a repetition period of the polarity pattern.
