Problems solved by technology

[0005] In the process of adhesion pressing, the temperature is too high or too low. If the temperature is too high, the fluidity of the glue will be good, which will affect the adhesion thickness of the glue. If the temperature is too low, the glue will solidify prematurely and affect the adhesion strength; and when the adhesion process When the temperature difference is too large, it is easy to cause damage to the glass and conductive layer, and the thickness of the adhesion is uneven, which affects the production quality

Abstract

The invention discloses a production method for a capacitive touch screen. The method includes the following steps: step 100. preparing a transparent electric level layer, and etching a capacitive sensing circuit on a transparent circuit board by using an integrated circuit manufacturing process; step 200. installing the transparent electric level layer, and pressing the transparent electric levellayer and a glass substrate into one body; and step 300. producing a touch screen to form into a shape, and adhering protective glass to the transparent electric level layer after the transparent electric layer is integrated. Through adoption of the scheme, optical cement is prevented from prematurely curing by controlling the time of constant temperature and cooling, thereby improving the adhesion strength, and the curing efficiency can be improved, and the curing time is shortened through the combination of air cooling and ultraviolet light; and the flatness during adhesion can be improved,uneven thickness of the optical cement is prevented, thereby improving the production quality, and further the cooling efficiency is improved by employing a mode of cooling roller extrusion.

Description

technical field [0001] The invention relates to the technical field of capacitive touch screens, in particular to a production method of capacitive touch screens. Background technique [0002] The structure of the capacitive touch screen is mainly to coat a transparent film conductor layer on the glass screen, and then add a protective glass outside the conductor layer. The double glass design can completely protect the conductor layer and the sensor. [0003] In recent years, with the rise of smart phones and tablet computers, the capacitive touch screen market has developed rapidly. From 2008 to 2012, China's touch panel shipments showed a rapid growth trend, and the average annual growth rate in the four years exceeded 40%, the industry is developing rapidly. In 2012, China's touch panel shipments were 426.64 million pieces, a year-on-year increase of 71.53%. Regarding the future development trend of the touch screen industry, analysts believe that in 2013, the touch sc...
