Abstract

The invention relates to a liquid crystal display and a common voltage driving method thereof. The liquid crystal display includes a liquid crystal display panel, a common voltage generator and a common voltage compensator. The liquid crystal display panel includes a common electrode, a first common voltage line and a second common voltage line. The common voltage compensator includes an input terminal and an output terminal. The common voltage generator is connected to the common electrode through the first common voltage line. The input end of the common voltage compensator is connected to the common electrode through the first common voltage line, and the output end is connected to the common electrode through the second common voltage line. The common voltage generator is used to provide a common voltage for the liquid crystal display panel, and the common voltage compensator is used to provide a compensated common voltage to the liquid crystal display panel according to the actual common voltage on the first common voltage line.

Description

technical field [0001] The invention relates to a liquid crystal display and a common voltage driving method thereof. Background technique [0002] Liquid crystal displays are widely used because of their low radiation, light, thin and small size, and low power consumption. With the maturity and innovation of related technologies, there are more and more types. [0003] see figure 1 , is a schematic diagram of a prior art liquid crystal display. The liquid crystal display 10 includes a liquid crystal display panel 11 , a timing controller 12 , a scan driver 13 , a data driver 14 and a common voltage generator 15 . The scan driver 13 and the data driver 14 are used to drive the LCD panel 11 , and the timing controller 12 is used to control the scan driver 13 and the data driver 14 . The common voltage generator 15 is used to provide the common voltage for the liquid crystal display panel 11 . [0004] The liquid crystal display panel 11 includes a plurality of parallel sc...
