Abstract
A liquid crystal display includes a pixel array, a gate driver, a data driver, a common voltage source, and a current duplication module. The gate driver is used to turn on a plurality of rows of pixels in the pixel array in sequence. The data driver is used to provide a plurality of data voltages to the turned-on pixels in the pixel array. The common voltage source is used to provide a common voltage. The current duplication module is coupled to a first side and a second side of the pixel array and is used to input two substantially equal currents to the first side and the second side of the pixel array respectively to provide the common voltage to the first side and the second side of the pixel array.
