Abstract

The invention relates to a production process of a touch screen. The production process includes the following steps that a substrate used for the touch screen is subjected to quenching and tempering;after quenching and tempering, the substrate used for the touch screen is subjected to ultraviolet irradiation; the processed substrate used for the touch screen is cleaned, and the surface of the substrate which is used for the touch screen and qualified in detection is printed with metal ink and baked; the baked metal ink forms a metal mesh pattern through laser sintering; the substrate used for the touch screen is coated with a conductive film layer through plating, a connector of a flexible printed circuit is in press fit with the substrate used for the touch screen, and glue sealing anddefoaming are conducted at the position of the connector of the flexible printed circuit. The invention provides the production process of the touch screen, the metal mesh pattern is formed through laser sintering, by controlling the laser output power, the laser scanning speed and the range of spacing between lines of the pattern formed after etching, the precision of the process pattern is improved, through the combination of the conductive film layer, the problem that the crystallinity of the substrate used for the touch screen is not enough and the light transmittance is thus low is solved, and the quality of products is effectively improved.

Description

Technical field [0001] The present invention relates to the technical field of touch screens, in particular to a production process of touch screens. Background technique [0002] Touch screen, also known as "touch screen" or "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts. As a newest computer input device, touch screen is currently the simplest and most convenient , A natural human-computer interaction method, mainly used in public information query, leadership office, industrial control, military command, video games, ordering songs, multimedia teaching, real estate pre-sales, etc. At present, in the manufacturing process of touch screens, there is poor process pattern accuracy. The substrate for touch screens has insufficient crystallinity, resulting in low light transmittance, thereby affecting product quality. Summary of the invention [0003] The present invention aims to solve the shortcomings of the prior art a...
