Problems solved by technology

In some existing technologies, touch signal lines and data lines or gate lines are arranged on the same layer, and are formed simultaneously through a patterning process. When arranged in the same layer, it is bound to reduce the area of ​​the pixel area, thereby reducing the aperture ratio of the touch display device; in order not to affect the aperture ratio of the touch display device, s...

Abstract

The invention provides a touch display substrate which comprises a plurality of touch electrodes and a plurality of touch signal lines, wherein the touch electrodes and the touch signal lines are formed on a base substrate, each touch electrode is electrically connected with at least one of the touch signal lines, each touch signal line comprises a first part and a second part which are arranged on different layers, the first part is electrically connected with the second part by via holes, the first part and a first layer metal graph of the touch display substrate are arranged on the same layer and made from the same material, the second part and the second layer metal graph of the touch display substrate are arranged on the same layer and made from the same material, the orthographic projection of at least one part of the first part on the base substrate coincides with the orthographic projection of the second layer metal graph on the base substrate, or the orthographic projection of at least one part of the second part on the base substrate coincides with the orthographic projection of the first layer metal graph on the base substrate. According to the technical scheme, the touch signal lines can be formed on the premise that the picture composition process is not added, and the influence to the aperture opening ratio of the touch display device can be reduced.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch display substrate, a preparation method thereof, and a touch display device. Background technique [0002] The touch panel is a device for positioning by calculating the coordinates of the touch points in the screen. The touch panel detects the user's touch position, then sends the detected information to the controller, converts it into coordinates, and sends To the central processing unit, at the same time accept the signal returned by the central processing unit and execute it to realize human-computer interaction. [0003] At present, most of the touch screens used in the market are capacitive touch screens, especially the new generation of touch devices represented by Apple mobile phones, which have greatly developed capacitive touch screens. The main application of capacitive touch screens is In products such as smartphones, tablets, and laptops. Cap...
