Method and apparatus for driving liquid crystal display device
First Claim
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 polarity inversion signal 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 a plurality of the polarity inversion signals are different from each other.
