Abstract

A manufacturing method of a capacitive touch screen comprises steps as follows: a piece of induction glass and a piece of carrier glass are attached to form a compound glass structure, the thickness of the induction glass is smaller than that of the carrier glass, and the carrier glass can support and protect the induction glass, so that the induction glass can be prevented from being damaged in the follow-up film coating, heating and attaching processes. The induction glass can be manufactured to be light and thin as required, so that the obtained touch screen is smaller in thickness. The high-temperature resistance of glass is improved greatly when compared with that of a PET (polyethylene terephthalate) material, the induction glass can be plated with an ITO (indium tin oxide) film under the high-temperature environment of above 300 DEG C, a compact thicker conductive film can be formed in the induction glass, and the obtained touch screen has good optical and electrical properties. With the adoption of the manufacturing method of the capacitive touch screen, the lighter and thinner touch screen with good light transmittance can be manufactured.

Description

technical field

[0001] The invention relates to touch screen technology, in particular to a method for preparing a capacitive touch screen. Background technique

[0002] Intelligence is the most important development trend of the manufacturing industry in the post-industrial era. The touch screen has better solved the bottleneck problem of human-computer interaction in the process of intelligence, and changed its business model to promote the healthy development of the entire industrial chain. According to the principle of touch sensing, existing touch screens are mainly divided into resistive, capacitive, and surface infrared touch screens. Among them, the capacitive touch screen has the advantages of simple structure, high light transmittance, friction resistance, resistance to environmental humidity and temperature changes, long service life, and multi-touch, etc., and it is becoming more and more dominant.

[0003] At present, there are mainly two types of capacitive to...
