Novel electrode lead capacitive screen manufacturing method and its product and touch screen terminal

Abstract

The invention is applicable to the technical field of touch screen production and provides a method for manufacturing a novel electrode lead capacitive screen, the novel electrode lead capacitive screen and a touch screen terminal. The method comprises the following steps of: (1) preparing an indium tin oxide (ITO) conductive film on a polyester (PET) base film; (2) preparing a copper film on the ITO conductive film by using a magnetically-controlled splutter coating method; (3) manufacturing ITO patterns, and forming an edge copper electrode lead at one time; (4) selectively etching the copper film on the middle ITO pattern, and reserving the ITO pattern to obtain PET thin film structures; and (5) sequentially adhering two PET thin film structures which are obtained in the step (4) and a piece of panel glass by using an optical adhesive to obtain the novel electrode lead capacitive screen. In the method for manufacturing the novel electrode lead capacitive screen provided by the invention, the magnetically-controlled splutter coating method is adopted to replace a silk-screening silver paste process to manufacture an electrode lead of a capacitive screen with mature technical means; and by the method, the good rate for manufacturing the capacitive screen having a film-film structure can be greatly improved, so that the manufacturing cost of the capacitive screen is saved.
