[0040] Please refer to image 3 and Figure 4 The first embodiment of the present invention provides an array substrate. The array substrate 10 is provided with a plurality of scanning lines 16 , a plurality of data lines 17 , a plurality of common lines 18 and a common electrode 11 .

[0041] A plurality of data lines 17 and a plurality of common lines 18 extend along the same direction, and a plurality of data lines 17 and a plurality of common lines 18 are arranged alternately in the direction of the scanning lines 16. On the array substrate 10, a plurality of scanning lines 16 and a plurality of The data lines 17 and the plurality of common lines 18 are insulated from each other and cross to define a plurality of pixel units P, and each pixel unit P is provided with a pixel electrode 13 .

[0042] The common electrode 11 includes a plurality of common electrode blocks 111 distributed in an array and insulated from each other, and each common electrode block 111 covers two...

[0070] 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.

[0071] Narrow viewing angle mode: please refer to Figure 8 In this embodiment, in the n...

Abstract

The invention discloses an array substrate and a drive method thereof, and a liquid crystal display device and a drive method thereof. The array substrate is provided multiple scanning lines, multipledata lines, multiple common lines, multiple common electrode blocks and multiple pixel units; each common public block covers two adjacent pixel units along a direction of the scanning lines; each pixel unit is provided with a pixel electrode inside; every two adjacent pixel units in the direction of the scanning lines are grouped and arranged on the array substrate; the pixel electrode of one pixel unit of each group of pixel units is connected with two scanning lines at the upper side and the lower side of the pixel unit and the data lines close to the series-connected switch elements through a first switch element and a second switch element in series connection, and the pixel electrode of the other pixel unit of the group is connected with the near scanning line and data line througha third switch element, and each common electrode block is connected with the scanning line and common line near the fourth switch element through the fourth switch 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. [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 viewi...
