Detailed Description
The present invention will be described in further detail below with reference to the drawings and detailed description for the purpose of better understanding of the technical solution of the present invention to those skilled in the art.
In the present invention, the term "co-layer arrangement" means that both are formed from the same material layer, so that they are in the same layer in a stacked relationship, but do not represent that they are equidistant from the substrate, nor that they are exactly the same as the other layer structures between the substrate.
In the present invention, the "patterning process" refers to a step of forming a structure having a specific pattern, which may be a photolithography process including one or more of the steps of forming a material layer, coating photoresist, exposing, developing, etching, photoresist stripping, and the like; of course, the "patterning process" may also be an imprinting process, an inkjet printing process, or other processes.
Example 1:

at least one first bridging electrode 4, located on the substrate 1, connects the touch electrodes 2 disconnected at the junction.
In other words, the touch electrode 2 is used for realizing the touch function of the display substrate, and the signal electrode 3 is used for realizing the network signal receiving function of the display substrate.
Because the distribution of the touch electrode 2 and the signal electrode 3 has a cross region where the signal electrode 3 and the touch electrode 2 cross each other, and the signal electrode 3 and the touch electrode 2 are arranged on the same layer, the signal electrode 3 and the touch electrode 2 interfere each other in the cross region.
In the display substrate of this embodiment, the touch electrode 2 located in the intersection area is disconnected, so that the signal electrode 3 is not disconnected in the intersection area, and meanwhile, the touch electrode 2 disconnected in the intersection area is connected through the first bridging electrode 4, that is, the touch electrode 2 is bridged, so that the respective performances of the touch electrode 2 and the signal electrode 3 can be realized.
In addition, the same layer arrangement of the signal electrode 3 and the touch electrode 2 can simplify the manufacturing process of the display substrate of the present embodiment, that is, only one patterning is needed to form the touch electrode 2 and the signal electrode 3.
