Patent ID: 8179351

Claim:
A liquid crystal display comprising: a liquid crystal display panel including a plurality of data lines, a plurality of gate lines crossing the data lines, and a plurality of liquid crystal cells; a data drive circuit that inverts a polarity of a data voltage supplied to the data lines in response to a polarity control signal; a gate drive circuit that supplies a gate pulse to the gate lines; and a timing controller that generates the polarity control signal and controls the data drive circuit and the gate drive circuit, wherein the timing controller allows the polarity control signal to have a different phase in each frame and allows the liquid crystal cells to be divided into a first liquid crystal cell group charged to the data voltage of a same polarity during two frame periods and a second liquid crystal cell group charged during a current frame period to the data voltage with a polarity opposite a polarity of the data voltage charged during a previous frame period, wherein the liquid crystal cells belonging to the first liquid crystal cell group and the liquid crystal cells belonging to the second liquid crystal cell group are arranged on one screen of the liquid crystal display panel, and wherein the liquid crystal cells belonging to the first liquid crystal cell group are successively charged to the data voltage of the same polarity during three or more frame periods at intervals of a predetermined time equal to or longer than two frame periods.
