Background technology
Capacitive touch screen is four layers of compound glass screen; the inside surface of glass screen and interlayer respectively scribble one deck ITO, and outermost layer is a skim silicon soil glassivation, and interlayer ITO coating is as workplace; draw four electrodes on four angles, internal layer ITO is that screen layer is to guarantee good working environment.When finger touch was on metal level, because people's bulk electric field, user and touch screen surface formed with a coupling capacitance, and for high-frequency current, electric capacity is direct conductor, so finger siphons away a very little electric current from contact point.This electric current divides the electrode on from touch-screen four jiaos and flows out, and the electric current of these four electrodes of flowing through is directly proportional with the distance of pointing four jiaos, and controller passes through the accurate Calculation to these four current ratios, draws touch point position.Form from the capacitive touch screen structure, its glass substrate occupies very big proportion; And during practical application, capacitive touch screen panel often all need embed in the corresponding electronic product, ink lay is to be printed on the glass-based flaggy in the existing capacitive touch screen panel, the thickness of ink lay that causes being positioned at the edge is thicker, and the OCA optics glue-line that the middle section that is positioned at ink lay needs should cost an arm and a leg with bonding middle section and the OCA optics glue-line that also needs to fill ink lay of lower floor, thereby cause OCA optical cement layer thickness thicker, and be easy to generate bubble, so cost has increased greatly; Secondly, the glass-based flaggy prints and adhesion technique simultaneously, is unfavorable for the raising of production efficiency and yield.Therefore how to reduce the use amount of OCA optics glue-line, avoid the generation of bubble, simultaneously, enhance productivity and yield, become the direction that those skilled in the art make great efforts.
Summary of the invention
The utility model provides a kind of capacitive touch screen panel, and this capacitive touch screen panel has reduced the use amount of OCA optics glue-line, has avoided the generation of bubble; Simultaneously, also enhance productivity and yield.
For achieving the above object, the technical solution adopted in the utility model is: a kind of capacitive touch screen panel, comprise glass-based flaggy, LCD liquid crystal display and have the first sensing film layer, the second sensing film layer of ITO sensing electrode figure respectively, bonding between the described glass-based flaggy and the first sensing film layer by an OCA optics glue-line, bonding between the described first sensing film layer and the second sensing film layer by the 2nd OCA optics glue-line;
The upper surface of described glass-based flaggy is bonding by the 3rd an OCA optics glue-line and a plastic film layers, surface coverage one ink lay that described plastic film layers contacts with the 3rd OCA optics glue-line, this ink lay is positioned at the fringe region of plastic film layers, thereby forms the viewing area at described plastic film layers middle section.
Further improved technical scheme is as follows in the technique scheme:
1. in the such scheme, described plastic film layers is PET film, polypropylene film, polyethylene film or polyvinyl chloride film.
2. in the such scheme, the described first sensing film layer, the second sensing film layer are PET film, polypropylene film, polyethylene film or polyvinyl chloride film.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
The utility model capacitive touch screen panel, bonding between its glass-based flaggy and the first sensing film layer by an OCA optics glue-line, bonding between the first sensing film layer and the second sensing film layer by the 2nd OCA optics glue-line, the upper surface of glass-based flaggy is bonding by the 3rd an OCA optics glue-line and a plastic film layers, surface coverage one ink lay that described plastic film layers contacts with the 3rd OCA optics glue-line, this ink lay is positioned at the fringe region of plastic film layers, thereby form the viewing area at described plastic film layers middle section, thereby reduced the use amount of OCA optics glue-line, avoided the generation of bubble, simultaneously, also enhance productivity and yield.
