Abstract

The invention relates to an LCD and a corresponding common voltage drive method. The LCD comprises a liquid crystal panel which comprises a first common voltage line, a second common voltage line, a common electrode line, a plurality of liquid crystal capacitances and a plurality of storing capacitances. Each liquid crystal capacitance comprises a common electrode and each storing capacitance comprises a storing capacitance electrode. A common voltage generator provides a common voltage for the storing capacitance electrode through the first common voltage line and at least one common voltage regenerator receives a feedback common voltage of the storing capacitance electrode through the second common voltage line and generates a regenerative common voltage according to the feedback common voltage which is charged to the common electrode through the common electrode 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, their types are also becoming more and more diverse. [0003] see figure 1 , is a schematic diagram of a circuit structure of a prior art liquid crystal display. The liquid crystal display 10 includes a liquid crystal panel 11 , 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 liquid crystal panel 11 . The common voltage generator 15 is used to provide the common voltage for the liquid crystal panel 11 . [0004] The liquid crystal panel 11 includes a plurality of parallel scanning lines 131 , a plurality of data lines 141 parallel to each other and perpendic...
