Abstract:
1. A driving apparatus for a liquid crystal display device, comprising: a liquid crystal display panel having a plurality of data lines and gate lines arranged in a matrix configuration; a data driver for supplying video data to the data lines; a gate driver for supplying gate pulses to the gate lines; and a timing controller for controlling polarity of the video data by supplying a selected polarity inversion signal from at least a first and second polarity inversion signals to the data driver and controlling a timing of the data driver and the gate driver according to a number of horizontal synchronization signals supplied during a data blanking period, wherein the number of horizontal synchronization signals supplied during the data blanking period is an odd-number of times, wherein the at least first and second polarity inversion signals are different from each other, and the video data polarity is controlled by the second polarity inversion signal.
