Embodiment 1

[0032] Such as figure 2 , image 3 As shown, this embodiment provides a touch substrate, which includes a plurality of touch electrodes 1, each touch electrode 1 is connected to a corresponding touch lead 11, at least some of the touch electrodes 1 have overlapping areas, and the touch The electrodes 1 overlap with the touch leads 11 corresponding to other touch electrodes 1 in the overlapping area.

[0033] Specifically, the touch substrate refers to a substrate for realizing a touch function, which may be a separate touch substrate, or simultaneously serve as a display substrate for display.

[0034] The touch electrode 1 is an electrode for realizing a touch function, and the touch electrode 1 may also be in different forms according to different touch methods. For example, they may be scanning electrodes or sensing electrodes for realizing mutual inductive touch, and may also be electrodes for realizing self-inductive touch. Preferably, here it is taken that the touch ...

Embodiment 2

[0056] This embodiment provides a method for preparing the above-mentioned touch substrate, which includes:

[0057] The step of forming touch electrodes and the step of forming touch leads, wherein each touch electrode is connected to a corresponding touch lead, at least some touch electrodes have overlapping areas, and the touch electrodes are in the overlapping areas corresponding to other touch electrodes. The touch leads of the touch electrodes overlap;

[0058] Between the step of forming the touch electrode and the step of forming the touch lead, it further includes: forming a shielding electrode in at least a part of the overlapping area.

[0059] Wherein, "the step of forming the touch electrodes and the step of forming the touch leads" means that the touch electrodes and the touch leads need to be formed separately, but there is no certain sequence for the formation of the two.

[0060] Preferably, the touch substrate is an array substrate of a liquid crystal displa...

Abstract

The invention provides a touch control substrate and a manufacturing method and touch control display device thereof, and belongs to the technical field of touch control. The problem that crosstalk is prone to happening between all touch control electrodes of an existing touch control substrate can be solved. The touch control substrate comprises a plurality of touch control electrodes which are connected with corresponding touch control leads. At least part of the touch control electrodes comprise overlapping areas. The overlapping areas of the corresponding touch control electrodes are overlapped with the touch control leads of the rest of the touch control electrodes. Shielding electrodes located between the corresponding touch control electrodes and the touch control leads are arranged in at least part of the overlapping areas.

Description

technical field [0001] The invention belongs to the field of touch technology, and in particular relates to a touch substrate, a preparation method thereof, and a touch display device. Background technique [0002] The In Cell Touch technology refers to a technology in which various structures for touch control are formed in a display substrate, so that the structure is relatively simple. [0003] A touch substrate structure such as figure 1 As shown, it is also the array substrate of liquid crystal display. The touch substrate includes common electrodes 2, wherein at least some of the common electrodes 2 are also touch electrodes 1; that is to say, these electrodes pass touch signals during touch control, and pass common voltage during display, so that they are both touch electrodes. 1, which is also the common electrode 2; of course, the touch substrate may also include some electrodes that are only used as the common electrode 2. Wherein, if a mutual inductive touch is...
