[0049] Based on the same inventive concept, the embodiment of the present application also provides a method for preparing a touch shielding film, including the following steps:
[0050] S1. Provide a substrate;
[0051] S2, preparing a touch circuit on one side of the substrate;
[0052] S3. Coating the above-mentioned shielding liquid on the other side of the substrate to prepare a shielding layer.
[0053] It should be noted that in the embodiment of the present application, the substrate used may be a flexible substrate, specifically PET, COP, COC, PI, PMMA, PC, etc.; specifically, a touch panel is prepared on one side of the substrate. The circuit is realized by conventional existing technology. For example, a conductive liquid can be coated on one side of the substrate to form a conductive layer, and then a protective liquid can be coated on the surface of the conductive layer to form a protective layer, and then coated on the edge of one side of the substrate. The con...
