Dynamic electronic mask plate system used for preparing monolithic integration capacitive touch screen through collage method

Abstract

The invention discloses a dynamic electronic mask plate system used for preparing a monolithic integration capacitive touch screen through a collage method. The dynamic electronic mask plate system comprises a substrate bearing system, a visual identification system, a filling graph design system, an image data processing system, a dynamic digital mask graph adjustment system and an electronic mask plate system. An electronic mask is used to replace a fixed metal pattern photoresistance mask plate in the prior art, the position of a filling graph is adjusted according to the deviation position and the angle of inclination of a small piece of glass in the production of preparing the monolithic integration capacitive touch screen through the collage method, and the small piece of glass having position, height and angle deviations is exposed, so that the large-scale volume production of OGS touch screens is achieved, the production efficiency is improved, and the dynamic electronic mask plate system is widely applied to the manufacturing of a multilayer composite membrane layer in a touch screen, an electronic product, a photovoltaic product or a PCB (printed circuit board) or implementing of perforated locating and sleeving between layers.

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 sm
