[0035] Please refer to image 3 and Figure 4 The first embodiment of the present invention provides a liquid crystal display device, including an array substrate 10 , a color filter substrate 20 opposite to the array substrate 10 , and a liquid crystal layer 30 located between the array substrate 10 and the color filter substrate 20 .

[0036] The array substrate 10 is provided with a plurality of scanning lines 16 and a plurality of data lines 17, and the plurality of scanning lines 16 and the plurality of data lines 17 are insulated from each other to define a plurality of pixel units P arranged in an array, and each pixel A pixel electrode 13 is disposed in the unit P, and each pixel electrode 13 is connected to a scan line 16 and a data line 17 adjacent to the first switch element 1 through the first switch element 1 .

[0037]A plurality of common lines 18 (marked by C1, C2, C3...) and a plurality of common electrode blocks 111 are also provided on the array substrate 1...

[0064] Please refer to Figure 8 and Figure 9 The difference between the liquid crystal display device provided by the second embodiment of the present invention and the first embodiment above is that the liquid crystal layer 30 in this embodiment uses negative liquid crystal molecules. With the advancement of technology, the performance of negative liquid crystal has been significantly improved, and its application has become more and more extensive. In this example, if Figure 8 As shown, in the initial state (that is, under the condition that no voltage is applied to the liquid crystal display device), the negative liquid crystal molecules in the liquid crystal layer 30 have a relatively large initial pretilt angle with respect to the substrate, that is, the negative liquid crystal molecules in the initial state are relative to the substrate. The substrate is in a tilted posture.

[0065] Narrow viewing angle mode: please refer to Figure 8 In this embodiment, in the n...

Abstract

An array substrate and its driving method, a liquid crystal display device and its driving method, wherein the array substrate is provided with a plurality of common lines and a plurality of common electrode blocks, the plurality of common lines and the plurality of data lines extend in the same direction, Each common line is correspondingly located directly above a data line and overlaps the data line up and down, and each common electrode block covers two adjacent pixel units along the direction of the scanning line, and each common electrode block communicates with the scanning line through the second switching element. and the common line connection, the common electrode blocks of each adjacent upper and lower rows are staggered in a manner of staggering one pixel unit, each pixel unit of each row is alternately connected to the two scanning lines located on the upper and lower sides of the row of pixel units, each Each pixel unit in a row is alternately connected to two data lines located on the left and right sides of the row of pixel units. The present invention can improve the problem of display unevenness (mura) in the display device and improve the image display quality.

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, and also relates to 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. [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 addi...
