Abstract

The invention provides a liquid crystal display device which comprises an LCD panel, an analysis unit and a public voltage circuit. The analysis unit receives display signals of two adjacent frames or display signals of two spaced frames and compares and analyzes the display signals of two frames; the public voltage circuit compensates and modulates public voltage according to analyzed results, and outputs the public voltage obtained after compensation and modulation to the LCD panel. The invention provides a method for driving the LCD 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 screen. [0003] Please refer to FIG. 1 , which is a schematic structural diagram of a liquid crystal display device in the prior art. The liquid crystal display device 100 includes a liquid crystal panel 101, a gate driver 102 and a source driver 103 for driving the liquid crystal panel 101, a timing controller for controlling the gate driver 102 and the source driver 103 104 and a common voltage circuit 105 ...
