[0044] Please refer to Figure 3 to Figure 5 , the first embodiment of the present invention provides an array substrate 20, the array substrate 20 is provided with a plurality of scanning lines 21, a plurality of data lines 22, a plurality of pixel electrodes 23, a plurality of common lines 24, a plurality of common electrode blocks 25 . A plurality of first thin film transistors 26 and a plurality of second thin film transistors 27 .

[0045] The plurality of scan lines 21 and the plurality of data lines 22 are insulated and intersect to define a plurality of pixel units P arranged in an array, and each pixel unit P is defined by two scan lines 21 and two data lines 22 .

[0046] The plurality of common lines 24 and the plurality of data lines 22 extend in the same direction and are arranged to overlap up and down. For example, the common lines 24 and the data lines 22 both extend along the vertical direction. The intervals can be completely overlapped or mostly overlapped,...

[0059] Please refer to Figure 6 to Figure 7 The second embodiment of the present invention provides an array substrate 20. The main difference between this embodiment and the above-mentioned first embodiment is that in the array substrate 20 of this embodiment, the plurality of common lines 24 are located at the plurality of data lines 22 directly below the Image 6 In order to facilitate drawing, the upper data line 22 is drawn narrower than the lower common line 24, but this should not be regarded as a limitation of the present invention. Specifically, each common line 24 and the corresponding data line 22 may completely overlap, or mostly overlap, that is, there may be a certain small misalignment between the two.

[0060] The array substrate 20 is also provided with a first conduction hole 201 that connects the pixel electrode 23 to the drain of the first thin film transistor 26, and a second conduction hole 201 that connects the common electrode block 25 to the drain of...

[0064] Please refer to Figure 8 The third embodiment of the present invention provides an array substrate 20. The main difference between this embodiment and the above-mentioned first embodiment is that in the array substrate 20 of this embodiment, the first thin film transistor 26 and the first thin film transistor 26 in each pixel unit P The second thin film transistors 27 are arranged diagonally and are respectively connected to different scanning lines 21 located on the upper and lower sides of the pixel unit P. For example, taking a pixel unit P in the first row as an example, the first thin film transistor 26 in the pixel unit P is connected to the scanning line G1 on the upper side of the pixel unit P, and the second thin film transistor 27 in the pixel unit P is connected to the scanning line G2 on the lower side of the pixel unit P; or, the first thin film transistor 26 in the pixel unit P is connected to the scanning line G2 on the lower side of the pixel unit P, an...

Abstract

Provided are an array substrate, a liquid crystal display device and a driving method. The array substrate is provided with a plurality of scanning lines, multiple USB cables, a plurality of pixel electrodes and a plurality of first thin film transistors, wherein the scanning lines cross with the USB cables in an insulation mode to define a plurality of pixel units each of which is internally provided with a first thin film transistor and a pixel electrode; the pixel electrode in each pixel unit is connected with one of the USB cables through the corresponding first thin film transistor; the array substrate is also provided with a plurality of common lines, multiple common electrode blocks and a plurality of second thin film transistors, and the common lines and the USB cables extend in a same direction and the common lines and the USB cables are arranged in a superimposed mode in the vertical direction; each pixel unit is internally provided with one second thin film transistor and one common electrode block, and the common electrode blocks are connected to the common lines adjacent to the second thin film transistors through the second thin film transistors. The array substrate, the liquid crystal display device and the driving method can switch a viewing angle from a narrow mode to a wide mode in different occasions, and solve the problem of uneven image display.

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...
