Problems solved by technology

But in this case, the entire pixel cannot play a normal display role, so this "repair" cannot completely repair point defects
In addition to the MVA LCDs described here, other types of LCDs in which pixels are composed of multiple sub-pixels suffer from similar deficiencies

Embodiment Construction

[0026] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. In the drawings, the same components are denoted by the same reference numerals.

[0027] image 3 A schematic diagram of a pixel structure on an array substrate of a liquid crystal display device is shown according to an embodiment of the present invention. The array substrate includes multiple scan lines and data lines, for example image 3 Scanning lines 21a, 21b and data lines 22a, 22b are exemplarily shown in FIG. The scanning lines 21a, 21b and the data lines 22a, 22b are intersected (for example, vertically intersected) and define an area called "pixel" on the array substrate. Each pixel is further divided into a first sub-pixel and a second sub-pixel, the first sub-pixel electrode 26a is formed in a region called "first sub-pixel", and the second sub-pixel electrode 26b is formed in a region called "second sub-pixel". pixels" area....

Abstract

The invention provides a liquid crystal display (LCD) device and an array substrate thereof. According to the invention, the array substrate comprises a plurality of scan lines, a plurality of data lines and pixels which are restricted by crosswise arranging the scan lines and the data lines. The pixels comprise a first sub-pixel electrode, a second sub-pixel electrode which is electrically separated from the first sub-pixel electrode, a first switch element used for controlling the first sub-pixel electrode, and a second switch element used for controlling the second sub-pixel electrode. Thearray substrate is characterized in that the second switch element can replace the first switch element to control at least a part of the first sub-pixel electrode when the control of the first switchelement on the first sub-pixel electrode can not be normally operated. The liquid crystal display (LCD) device and the array substrate thereof can completely repair the point defects of the pixels, and greatly improve the yield of the LCD device and the array substrate, without increasing the production cost nearly.

Description

technical field [0001] The invention relates to a liquid crystal display device and an array substrate of the liquid crystal display device. Background technique [0002] Liquid crystal display (LCD) has the advantages of lightness, thinness, and low power consumption, and is widely used in modern information equipment such as computers, mobile phones, and personal digital assistants. In order to realize wide viewing angles in liquid crystal display devices, various technologies have been developed, such as twisted nematic liquid crystal (TN) display with wide viewing film (wideviewing film), in-plane switching (IPS) liquid crystal display, Fringe Field Switching (FFS) LCDs and Multi-Domain Vertical Alignment (MVA) LCDs. [0003] The multi-domain vertical alignment liquid crystal display is provided with alignment protrusions or slits on the color filter substrate or the thin film transistor array substrate, which can make the liquid crystal molecules arrange in multiple di...
