[0035] Please refer to Figure 3 to Figure 6 The liquid crystal display device provided by the first embodiment of the present invention includes an array substrate 20 , a color filter substrate 30 disposed opposite to the array substrate 20 , and a liquid crystal layer 40 located between the array substrate 20 and the color filter substrate 30 .

[0036] A plurality of scan lines 21 and a plurality of data lines 22 are disposed on the array substrate 20 . The plurality of scan lines 21 and the plurality of data lines 22 are insulated and intersect to define a plurality of pixel units arranged in an array. Each pixel unit is provided with a pixel electrode 23 , a common electrode 24 and a thin film transistor 26 , and the pixel electrode 23 is connected to the scanning line 21 and the data line 22 adjacent to the thin film transistor 26 through the thin film transistor 26 . Specifically, the thin film transistor 26 includes a gate, a source and a drain, wherein the gate is el...

[0059] Please refer to Figure 11 and Figure 12The difference between the liquid crystal display device provided in this embodiment and the first embodiment above is that the liquid crystal layer 40 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 11 As shown, in the initial state (that is, the situation where no voltage is applied to the liquid crystal display device), the negative liquid crystal molecules in the liquid crystal layer 40 have a relatively large initial pretilt angle with respect to the substrates 20 and 30, that is, the negative liquid crystal molecules in the initial state The state is an inclined posture with respect to the substrates 20 , 30 .

[0060] Narrow viewing angle mode: please refer to Figure 11 In this embodiment, in the narrow viewing ang...

Abstract

The invention discloses 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 pixel electrodes, a plurality of common electrodes, a plurality of first conductive strips, a plurality of thin film transistors, a first voltage line and a second voltage line; a pixel electrode and a common electrode are arranged in each pixel unit; the first conductive strips extend in the scanning line direction and are located on the upper sides of the corresponding scanning lines tooverlap the scanning lines, and the common electrodes in each row of pixel units are connected to the same first conductive strip; the first conductive strips are alternately connected to the first voltage line and the second voltage line in the data line direction; the pixel electrodes in each row of pixel units are alternately connected to two scanning lines on the upper and lower sides of the row pixel units through the corresponding thin film transistors, and the pixel electrodes in each column of pixel units are alternately connected to two data lines on the left and right sides of the column pixel units through the corresponding thin film transistors.

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...
