Patent ID: 8031153

Claim:
A liquid crystal display, comprising: a liquid crystal display panel that has a plurality of data lines and a plurality of gate lines, which are crossed each other, and pixels, which are defined by the lines; a gate driver that supplies scanning pulses to the gate lines, and changes a supply sequence of the scanning pulses for each frame; a data driver that converts digital video data into data voltages and periodically inverts a polarity of the data voltages to supply the data voltages in accordance with a supply sequence of the scanning pulses; and a timing controller that supplies the digital video data to the data driver, and controls the data driver and the gate driver, and wherein a polarity of data voltages, which are supplied to the liquid crystal display panel, is inverted for each liquid crystal cell and a polarity of a data voltage which is outputted from the data driver, is inverted for every two to four horizontal periods, wherein the liquid crystal display panel is divided into k line blocks (k is a positive integer less than n/2) having n gate lines (n is an even number), and each of the line block is divided into a first and second sub-blocks having i gate lines (i is an even number less than n), wherein the gate driver shifts the scanning pulse toward an up-scanning direction and a down-scanning direction in accordance with a scanning direction signal from the timing controller.
