Problems solved by technology

[0003] The GG structure touch screen is composed of sensor glass + tempered glass cover. The GG structure touch screen is widely used due to its performance advantages such as hard wear resistance, corrosion resistance, high light transmittance, smooth handling, and high reliability. The existing GG structure touch screen has high production cost, difficult manufacturing process, and many uncontrollable factors, resulting in low product yield and poor performance

Abstract

The invention relates to the technical field of touch screens, in particular to a manufacturing process of a GG-structure touch screen, which places the silk screen printing conductive silver paste process in front of the printing insulating glue process, and uses only one layer of insulating glue. Compared with the existing traditional technology The use of two layers of insulating glue reduces the process of a yellow light, simplifies the process of touching the screen, and reduces the production cost. The present invention adds a process of pasting a protective film in the manufacturing process to prevent the product from being polluted or scratched during the production process, which affects the yield rate of the product. To sum up, through the above-mentioned manufacturing process, the yield rate of the manufactured product is high and the performance is better than that of similar products.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a manufacturing process of a GG structure touch screen. 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 GG structure touch screen is composed of sensor glass + tempered glass cover. The GG structure touch screen is widely used due to its performance advantages such as hard wear resistance, corrosion resistance, high light transmittance, smooth handling, and high reliability. The existing GG-structure touch screen has high production cost, difficult manufacturing process, and many uncontrollable factors, resulting in low product yield and poor performance.
