Abstract

The invention discloses an array substrate and a driving method thereof, and a liquid crystal display device and a driving method thereof. The array substrate is provided with a plurality of scanninglines, a plurality of data lines, and a plurality of pixel units, and further provided with a plurality of common lines and a plurality of common electrode blocks, wherein each common electrode blockcovers two adjacent pixel units at the same time. Pixel electrodes in a first pixel unit are connected to two adjacent scan lines and one data line through a first switching element and a second switching element. The first switching element has a control end connected to one scanning line, one conductive end of the first switching element is connected to the other scanning line, and another conductive end of the first switching element is connected to a control end of the second switching element. Two conductive ends of the second switching element are respectively connected to the pixel electrodes and the data lines. Pixel electrodes in a second pixel unit are connected to the adjacent scan lines and data lines through a third switching element. Each common electrode block is connected to the adjacent scan lines and the common lines through a fourth switching element.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to an array substrate and a driving method thereof, a liquid crystal display device and a driving method thereof. 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. 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,...
