The protection film has automatic bubble-free lamination and anti-scratching functions, and is convenient to operate; the definition is further improved.
Description
Technical field
The utility model relates to a kind of capacitance plate sticking film for mobile phone, relates in particular to a kind of diaphragm for capacitive touch screen.
Background technology
Along with the high speed development of touch technology, the capacitive touch screen with multi-point touch function and stronger sensitivity is replacing traditional resistive touch screen gradually, obtains more and more application widely.The capacitive touch screen of prior art all adopts between finger and the electrode of inductive layer and realizes Capacitance Coupled, when finger touch is on metal level, due to people's bulk electric field, user and touch screen surface form with a coupling capacitance, for high frequency electric, electric capacity is direct conductor, so finger siphons away a very little electric current from contact point.This electric current divides electrode on from touch-screen four jiaos and flows out, and the electric current of these four electrodes of flowing through is directly proportional to the distance of finger to four jiaos, and controller draws the position of touch point by the accurate Calculation to these four current ratios.Higher just because of its sense of touch remolding sensitivity, when being vulnerable to external object at not use state, it disturbs, for example: mobile phone is placed in pocket, encounter because of carelessness touch-screen, may cause faulty operation, bring puzzlement to the user of service, perhaps display is not using state, does not wish that other people touch arbitrarily situations such as producing interference.
Summary of the invention
The utility model provides a kind of diaphragm for capacitive touch screen; this diaphragm that is used for capacitive touch screen has been avoided extraneous its interference; realize the effect that shielding is disturbed, and had Automatic-exhausting pickle applying and anti-scratch function, both facilitated operation also further to improve definition.
For achieving the above object; The technical solution adopted in the utility model is: a kind of diaphragm for capacitive touch screen; Comprise laminated polyester film and a separating film layer as base material; Described laminated polyester film upper surface scribbles wearing layer; Described laminated polyester film lower surface is coated with a conductive layer; Be coated with the organic pressure-sensitive gel layer between this conductive layer and separating film layer; Described organic pressure-sensitive gel layer thickness is 10 ~ 35 μ m; The surface that this organic pressure-sensitive gel layer contacts with separating film layer has several juts; Thereby forming surface roughness is the contact-making surface of 2.821 ~ 3.894 μ m; Described conductive layer is 1:10 ~ 35 with organic pressure-sensitive gel layer thickness ratio.
In technique scheme, further improved technical scheme is as follows:
1. in such scheme, described laminated polyester film is PET film, polypropylene film, polyethylene film or polyvinyl chloride film.
2. in such scheme, the thickness of described laminated polyester film is 50 ~ 125 μ m.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1. the utility model is used for the diaphragm of capacitive touch screen; it comprises laminated polyester film and a separating film layer as base material; described laminated polyester film upper surface scribbles wearing layer; wearing layer has higher pencil hardness and wearability; function with the scratch of preventing; and the surface that the organic pressure-sensitive gel layer contacts with separating film layer has several juts; thereby forming surface roughness is the contact-making surface of 2.821 ~ 3.894 μ m; exhaust bubble effect is good; attaching process is easy; workable, also further improved definition.
2. the utility model is used for the diaphragm of capacitive touch screen; It comprises laminated polyester film and a separating film layer as base material; Described laminated polyester film upper surface scribbles wearing layer; Described laminated polyester film lower surface is coated with a conductive layer; Be coated with the organic pressure-sensitive gel layer between this conductive layer and separating film layer; Described organic pressure-sensitive gel layer thickness is 10 ~ 35 μ m; After fitting in capacitive touch screen by the anti-interference diaphragm of said structure; Thereby having between the electrode that shields external object and inductive layer, conductive layer can not realize Capacitance Coupled; Therefore external object acts on touch screen and can not have influence on its use; When staff is encountered induction electrode accidentally; Applying due to shielding interference protection film; Intercept the capacitance variations between electrode and ground; Thereby can not have influence on circuit integral capacitor characteristic; Touch-screen can not use.Thereby avoided the interference of external substance to it, realized the effect that shielding is disturbed.
