Problems solved by technology

In high-resolution touch screens, in order to improve the transmittance of the liquid crystal display panel, the distance between adjacent pixel electrodes in the array substrate is small. When there is an alignment deviation between the array substrate and the color filter substrate, the liquid crystal display panel is prone to color shift Phenomenon, resulting in poor quality of the LCD panel

[0048] The second embodiment of the present invention also provides an array substrate. Figure 2a A schematic partial top view of an array substrate provided in the second embodiment of the present invention. see Figure 2a , the embodiment of the present invention and the first embodiment Figure 1e The arrangement of the auxiliary wires is the same, the difference is that each pixel electrode 170 is electrically connected to at least one auxiliary wire 180 .

[0049] The storage capacitor of the array substrate is mainly composed of the pixel electrode 170 and the common electrode block 150 . In a high-resolution touch screen, the smaller area of ​​the pixel electrode 170 leads to a lower storage capacitance, which makes the existing high-resolution liquid crystal display panels prone to display defects such as flicker and crosstalk.

Abstract

The invention provides an array substrate, a liquid crystal display panel and a liquid crystal display device. The array substrate comprises: scanning lines and data lines intersecting each other to define a plurality of pixel units, each pixel unit comprising a thin film transistor and a pixel electrode connected to the thin film transistor; a plurality of common electrode blocks used for sensing the touch of users; a plurality of sensing lines each of which is electrically connected with one corresponding common electrode block; and a plurality of auxiliary conductors arranged on the same layer as the sensing lines. Each auxiliary conductor is located between two adjacent sensing lines and the auxiliary conductors are insulated from the common electrode blocks. The sensing lines and the auxiliary conductors in the array substrate together block light, so that the problems that the phenomenon of color cast occurs if contraposition bias exists between the array substrate and a colored film substrate in the liquid crystal panel with the array substrate, and the display quality of the liquid crystal display panel is improved.

Description

technical field [0001] The present invention relates to a display device, in particular to an array substrate, a liquid crystal display panel and a liquid crystal display device. Background technique [0002] Liquid crystal displays (Liquid Crystal Displays, LCDs) are widely used in various display devices such as smart phones, notebook computers, and monitors due to advantages such as good portability and low power consumption. [0003] Currently, touch screens can be classified into plug-in touch screens, surface-covered touch screens, and built-in touch screens according to the positions of touch electrodes. Among them, the plug-in touch screen directly adds touch electrodes outside the LCD. This method makes the overall thickness of the whole machine thicker and the light transmittance becomes lower. Covering the surface touch screen is to make touch electrodes outside the color film substrate of the LCD. This method reduces the thickness of the whole machine, but incre...
