Abstract
A liquid crystal display includes: a liquid crystal display panel including data lines and gate lines crossing each other; a timing controller that maps data of an input image to polarity patterns of 1-dot inversion and 2-dot inversion, counts the number of positive data and the number of negative data, determines whether any one of the positive data and negative data becomes dominant or not based on a difference between the counted numbers, and selects either one of the 1-dot and 2-dot inversions; a data driving circuit that converts the data of the input image into data voltages to be supplied to the data lines and inverts the polarity of the data voltages by the selected dot inversion; and a gate driving circuit that sequentially supplies gate pulses synchronized with the data voltages to the gate lines.
