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 public lines, a plurality of pixel electrodes, a plurality of public electrodes, a plurality of first thin film transistors, a plurality of second thin film transistors and a plurality of conductive strips. The public lines and the data lines extend in the same direction. Every two adjacent data lines form a group, so multiple groups are formed. The public lines and the data lines are arrayed in the direction of the scanning lines alternately. Two lines of pixel units are arranged between every two adjacent data lines, and one public line is arranged between the two lines of pixel units. Each pixel electrode is connected with the corresponding scanning line and the corresponding data line through the corresponding thin film transistor. Each public electrode is connected with the corresponding scanning line and the corresponding public line through the corresponding second thin film transistor. The conductive strips and the data lines extend in the same direction, and the publicelectrodes of one of the two lines of pixel units which cover the data lines and are located on the two sides of the conductive strips are connected to the conductive strips.

Description

technical field [0001] The 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 (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 occupies a dominant position in the field of flat panel display. [0003] With the continuous advancement of liquid crystal display technology, the viewing angle of the display has been expanded from about 120° to more than 160°. While enjoying the visual experience brought by the large viewing angle, people also hope to effectively protect commercial secrets and personal privacy. Avoid commercial loss or embarrassment caused by information leakage on the screen. Therefore, in addition to a wide viewing angle, it is also required that the displa...
