Embodiment Construction

[0024] The present invention will be described in detail below with reference to the drawings and embodiments.

[0025] Before introducing the present invention, the liquid crystal panel suitable for the array substrate of the present invention will be described. The array substrate and the color filter substrate are attached relatively, and then liquid crystal is added between the array substrate and the color filter substrate to obtain a liquid crystal panel. Among them, the parallel plate capacitance formed by the pixel electrode on the array substrate and the common electrode on the color filter substrate is liquid crystal capacitance, and the parallel plate capacitance formed by the pixel electrode on the array substrate and the common electrode on the array substrate is storage capacitance.

[0026] refer to image 3 , In one embodiment of the array substrate of the present invention, the array substrate includes a pixel electrode layer 31, a first touch electrode laye...

Abstract

The invention discloses an array substrate and a touch screen. The array substrate includes a pixel electrode layer, a first touch electrode layer, an insulating layer and a second touch electrode layer stacked on the first touch electrode layer in sequence. ; wherein the pixel electrode layer does not overlap with at least one of the first touch electrode layer and the second touch electrode layer, and there is no insulating layer at least in the vertical projection area of ​​the pixel electrode layer. Through the above method, the present invention can reduce the parasitic capacitance between the touch electrodes without affecting the size of the liquid crystal capacitance and the storage capacitance.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to an array substrate and a touch screen. Background technique [0002] With the continuous development of electronic technology, touch screens have gradually become popular in people's lives. The touch screen has the advantages of ruggedness, fast response, space saving, and easy communication. Using the touch screen, users only need to touch the graphic characters on the screen with their fingers to realize the operation of the host, thus making the human-computer interaction more straightforward. . [0003] The touch screen includes a surface-covered touch screen (On-cell Touch Panel) and an embedded touch screen (In-cell Touch Panel). Among them, the embedded touch screen is to embed the touch sensing function into the metallurgical pixels, which can better realize the thinning and lightening of the panel, and is favored by manufacturers. [0004] Such as figure 1 as ...
