Abstract:
A liquid crystal display includes a liquid crystal display panel, a timing controller to generate a dynamic charge share control signal to indicate a time at which the gray level of a data voltage is changed from a white gray level to a black gray level and a time at which the polarity of the data voltage is inverted, and to detect weakness patterns and generate a dot inversion control signal for widening a horizontal polarity inversion time of data voltages when the weakness patterns are input, wherein the liquid crystal display panel includes first and second liquid crystal cell groups whose polarity is inverted every 2 frame periods, and a polarity inversion time of the first liquid crystal cell group and a polarity inversion time of the second liquid crystal cell group overlap.
