Abstract

The present invention relates to the technical field of touch screens, in particular to an improved manufacturing process of touch screens with PG structure. In the present invention, the process of silk screen conductive silver paste is placed in front of the process of printing insulating glue, and only one layer of insulating glue is used. Compared with the existing There is a traditional technology that uses two layers of insulating glue, which reduces a yellow light process, simplifies the process of touching the screen, and reduces the production cost; The selection of pulp is controlled in several aspects, so that the product yield of the present invention is high and the performance is also greatly improved compared with similar products.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to an improved manufacturing process of a touch screen with a PG 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] The PG structure touch screen is composed of sensor glass + PET plastic cover structure. The PG structure touch screen is widely used due to the advantage of low production cost. However, the existing PG structure touch screen has many uncontrollable factors, resulting in low product yield. Poor performance. Contents of the invention [0004] The object of the present invention is to provide an improved manufacturing process of a touch screen with a PG structu...
