Claim Text:
1. A method for driving a liquid crystal display panel, the liquid crystal display panel including a plurality of rows of basic pixels, a plurality of rows of gate lines, a plurality of data lines arranged in columns, and a 3D black screen data control module, wherein each row of basic pixels is divided into a row consisting of black matrix sub-pixels and a row consisting of color sub-pixels, both the black matrix sub-pixels and the color sub-pixels are connected with corresponding column of data lines and corresponding gate lines, each 3D black screen data control module is connected between two data lines which are supplied with voltages with opposite polarities, and each data line is only connected with one 3D black screen data control module, wherein, when displaying a 3D image, the method includes steps of: determining that it is needed to input data to the black matrix sub-pixels; and inputting a control signal to the 3D black screen data control module, the 3D black screen data control module, based on the received control signal, making the two data lines, which are connected with the 3D black screen data control module, be electrically conducted to each other while the two data lines are supplied with voltages with opposite polarities during a whole time period for displaying the 3D image, so that sharing charges on the two data lines are neutralized to obtain a lower level, which is inputted as black screen data to corresponding black matrix sub-pixels, and data lines connected with different 3D black screen data control modules are not electrically conducted to one another.
