Abstract

The invention provides a liquid crystal display device which comprises a liquid crystal panel, a data processing unit and a common voltage circuit, wherein, the data processing unit respectively receives the display signals of odd number series and the display signals of even number series, and carries out comparative analysis to the display signals of the odd number series and the display signals of the even number series; the common voltage circuit adjusts the common voltage according to analysis results, and outputs the adjusted common voltage to the liquid crystal panel. The invention also provides a driving method of the liquid crystal display device at the same time.

Description

technical field [0001] The invention relates to a liquid crystal display device and a driving method thereof. Background technique [0002] Liquid crystal display devices are widely used in modern information equipment, such as monitors, televisions, mobile phones, and digital products, due to their advantages of light weight, low power consumption, low radiation, and easy portability. Generally, a liquid crystal display device controls the passing amount of light through the rotation of liquid crystal molecules in each pixel unit, so as to realize the display of the picture. [0003] When a unidirectional voltage is applied to both ends of the liquid crystal molecules, if the unidirectional voltage lasts for a long time, that is, when the screen always displays the same gray scale, the liquid crystal molecules are prone to electrochemical reactions and the photoelectric properties of the liquid crystal molecules are damaged. Therefore, in order to ensure the life of the li...
