Abstract
An exemplary liquid crystal display () includes a plurality of pixel units () each including a pixel electrode () and a common electrode (), a data driving circuit () providing a plurality of data voltages to each pixel electrode, a common voltage generating circuit () providing a common voltage to each common electrode, and a gamma voltage generating circuit () providing gamma voltages to the data driving circuit. The plurality of pixel units are arranged in a matrix. The voltage difference between the data voltage and the common voltage in each pixel unit is a sum of a main voltage and an auxiliary voltage with periodical change. An absolute value of the main voltage is constant. An absolute value of the auxiliary voltage is less than the absolute value of the main voltage. A sum of the auxiliary voltage is zero in a minimum period.
