Based on the same concept as the touch module embodiment, the present embodiment further provides a method for manufacturing a touch module, as shown in fig. 4, including the following steps:
1) Forming a plurality of first bridge members 111 of a touch electrode structure on the fabricated display substrate 200; the display substrate 200 may include a plurality of sub-pixel units.

Specifically, an electrode material may be first used to deposit an electrode layer on the display substrate 200, and then a mask with a suitable opening is used to pattern the whole film layer, so as to obtain the touch electrode structure.

Specifically, referring to the manufacturing process of the green sub-color film layer 21, a whole red film layer (or a whole blue film layer) can be formed on the display substrate 200, then the red sub-color film layer 22 (or the blue sub-color film layer 23) is formed by patterning, and then the blue sub-color film layer 23 (or the red sub-color film layer 22) is formed by adopting a similar process.
The process used in each step is only one implementation mode of the present embodiment, and is not limited to this application, and any specific process may be used as long as the above manufacturing method can be implemented.
5) The black matrix 30 is formed on the touch electrode structure, and the projection of the black matrix 30 on the plane parallel to the display substrate 200 completely covers the projection of the touch electrode structure on the plane parallel to the display substrate 200, so as to enhance the shading effect on the touch electrode structure.
