Description

technical field [0001] The invention relates to a touch screen manufacturing system, in particular to a mask plate system in the manufacturing process of a monolithic integrated capacitive touch screen. Background technique [0002] The traditional capacitive touch screen is a multi-layer composite glass screen. The inner surface and the interlayer of the glass screen are each coated with a conductive layer, and the outermost layer is a thin layer of glass protective layer. The structure of this touch screen is relatively complicated and the production cost is high. [0003] The touch screen based on OGS technology integrates the touch sensor (Touch Sensor) and the cover glass (Cover Glass), that is, the ITO conductive layer is coated on the inside of the general cover glass, so that the single piece of glass not only has the strength of the cover glass, Security, as well as touch function, is considered to be the development trend of touch screen technology for consumer ele...

Problems solved by technology

The large-scale process mode in which small pieces are collaged on a large-scale carrier can achieve industrialized mass production due to its high output and scale benefits. The collage method to make capacitive screens has become the first choice among various solutions. However, there are key positioning design problems in the collage method to make capacitive screens.

[0005] At present, touch screen manufacturers mainly use the parallel light exposure mode: small pieces of collage need to use glue to bond the two layers of glass together, because the use of glue in the bonding process will cause the problem of drifting of the small piece of glass after positioning The position deviation between them is more than 20um, and the angle will also deviate. However, the mask plate used to block light for parallel light exposure is a fixed pattern. After exposure, there are angle and position deviations between the pattern formed on the glass and the positioning of the small piece. , resulting in the failure of mass production of the product

[0006] Obviously, due to the above positioning problems, the mass production of integrated capacitive touch screens produced by the splicing method is seriously hindered, and it cannot meet the needs of industrial production.
