ABSTRACT:
A liquid crystal display includes a timing controller to activate a dynamic charge share control signal to indicate a time at which the gray level of the 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 activate a dot inversion control signal for widening a horizontal polarity inversion period of data voltages to be supplied to the data lines when a weakness patterns are input, and a data driving circuit supplying one of a common voltage and a charge share voltage to data lines only when the gray level of data is changed from the white gray level to the black gray level and when the polarity of the data voltage in response to the dynamic charge share control signal.
