[0031] Example: such as figure 1 , figure 2 Shown, the preparation technology of a kind of capacitive touch screen of the present invention, it comprises the following steps:
[0032] (1) Lay the transparent conductive layer 3 on the substrate 4, and coat the acid-resistant film 2 on the transparent conductive layer 3 according to the set conductive pattern. The acid-resistant film 2 is used to protect the part of the transparent conductive layer 3 that does not need to be etched ;
[0033] (2) if figure 2 As shown, the target is set on the acid-resistant film 2, and the transparent acid and alkali resistant material 1 is coated on the target; figure 1 Among them, the diagram is a structural diagram after etching, and the acid-resistant film 2 is the target;
[0034] (3) Etching and removing the film, the part of the transparent conductive layer 3 that is not coated with the acid-resistant film 2 is acid-etched, thereby forming a conductive pattern on the substrate 4, an...
