Abstract

The invention relates to the technical field of touch screen conductive films, in particular to a production technology of a touch module with a GF2 double-sided conductive film structure. The production technology includes the steps of A), applying dry films, namely applying the dry films on two sides of a conductive film; B), exposing and developing; C), performing first etching and stripping; D), performing acid-resisting printing; E), performing second etching and stripping; F), performing insulation printing; G), slitting the applied film. On the basis of dry film application, the touch module with the GF2 double-sided conductive film structure is obtained by means of the first etching and the second etching; the touch module with the GF2 double-sided conductive film structure is light and thin and can be made into a touch screen with a narrow frame, and products made by the production technology are high yield, good in performance and improved compared with similar products.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a manufacturing process of a touch module with a GF2 double-sided conductive film structure. Background technique [0002] The touch screen is an input device that significantly improves the man-machine interface, and has the advantages of intuition, simplicity and speed. Touch screens have been widely used in many electronic products, such as mobile phones, PDAs, multimedia, public information inquiry systems, and the like. [0003] Traditional touch technology uses a double-layer glass touch module, which is not only heavy, but also cannot be made into a touch screen with a narrow frame. GF2 architecture touch technology means that ITO pattern [RX] and [TX] are placed on ITO Film at the same time. GF2 is lighter and thinner than traditional double-layer glass touch module, and can be made into a touch screen with narrow borders. At the same time, the main raw materials ...
