Abstract

The invention provides an array substrate, a liquid crystal display device and a driving method. The array substrate is provided with a plurality of scanning lines, a plurality of data lines, a plurality of pixel electrodes and a plurality of first thin film transistors and further provided with a plurality of public lines, a plurality of public electrode blocks and a plurality of second thin film transistors. The scanning lines, the data lines and the public lines are insulated and crossed to define and form a plurality of pixel units. Two lines of pixel units are arranged between every two adjacent data lines, one public line is arranged between the two lines of pixel units, and two scanning lines are arranged between every two adjacent lines of pixel units. Each pixel unit is internally provided with one first thin film transistor, one pixel electrode, one second thin film transistor and one public electrode block. The pixel electrodes are connected with the data lines through the first thin film transistors. The public electrode blocks are connected with the public lines through the second thin film transistors. Wide vision and narrow vision can be switched on different occasions, and the problem that image quality display is not uniform is solved.

Description

Technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to an array substrate, a liquid crystal display device and a driving method. Background technique [0002] Liquid crystal display (LCD) has the advantages of good image quality, small size, light weight, low driving voltage, low power consumption, no radiation, and relatively low manufacturing cost, and it is dominant in the flat panel display field. [0003] With the continuous advancement of liquid crystal display technology, the viewing angle of the display has been widened from about 120° to more than 160°. While enjoying the visual experience brought by the large viewing angle, people also hope to effectively protect trade secrets and personal privacy. Avoid business losses or embarrassment caused by leakage of screen information. Therefore, in addition to the wide viewing angle, the display device needs to be switchable to a narrow viewing angle. [0004] The c...
