Abstract
The utility model provides a transparent hardening-coating film for a capacitive touch screen. A pre-coating substrate is coated on two surfaces of base materials of the hardening-coating film. A transparent hardening-coating layer and a hardening- shadow-eliminating layer are respectively coated on the pre-coating substrate. The transparent hardening-coating film for the capacitive touch screen can resolve a problem that light ray can produce interference ripples as the light ray are reflected by different interfaces. 'Shadow' phenomenon of a capacitive screen conducting film can be lightened or eliminated. Visuality of the touch screen is improved. Requirements of the capacitive touch screen can be achieved.
Description
Technical field
The utility model belongs to the touch screen technology field, particularly a kind of capacitive touch screen transparent hardened film.
Background technology
Touch-screen mainly is divided into two kinds of resistance-type and condenser types, and the general plating tin indium oxide that adopts is as conductive layer, and its carrier is glass or optics PET film.Two-layer or the multi-layer film structure of the many employings of early stage group screen, along with the lightening requirement of screen, nowadays touch-screen adopts glass+optics PET film or optics PET film+optics PET film more, glass is because of its skin hardness high (8H), need not cure process, and optics PET film surface hardness is lower, be generally HB, consider for durability, must carry out hardening coat to its surface processes, make optics PET film surface hardness be increased to 2-3H, harveyed optics PET film, we are referred to as cured film or hardening film.
The structure of capacitive touch screen mainly is in the thin-film conductor layers of glass screen plating layer of transparent, adds the lastblock cover glass at conductor layer again.Capacitive touch screen all plates long and narrow electrode on touch-screen four limits, in electric conductor, form a low-voltage AC electric field, during user's touch screen, because people's bulk electric field, can form a coupling capacitance between finger and conductor layer, the electric current that four limit electrodes send can flow to the contact, is directly proportional with the distance of finger to electrode and electric current is strong and weak, be positioned at ratio and power that controller after the touch screen just can calculate electric current, accurately calculate the position of touch point.But in the actual use procedure, capacitance plate conducting film group screen adds and tends to etch pattern or lines man-hour, for transparent hardened film, owing to having a plurality of interfaces between the different layers, the reflected light that forms when light arrives different interface on the one hand is because existing wave path-difference to produce the interference line, the boundary reflection of different interface phases causes light transmission rate to reduce on the other hand, as seen simultaneously the multilayer interface is relevant can make the etched pattern of capacitance plate or svelteness when strengthening, be exactly " shadow " phenomenon of our the common capacitance plate conducting film of saying, it directly affects the display effect of touch screen.
The utility model content
Technical problem to be solved in the utility model is the problems referred to above that exist for prior art, and a kind of capacitive touch screen transparent hardened film is provided.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is:
A kind of capacitive touch screen transparent hardened film, it applies respectively pre-priming operation on two surfaces of base material, applies respectively transparent hard layer and the sclerosis shadow layer that disappears on the surface of pre-priming operation.
The disappear thickness of shadow layer of above-mentioned capacitive touch screen transparent hardened film, described sclerosis is 2.0 ~ 6.0 μ m.
Above-mentioned capacitive touch screen transparent hardened film, the described sclerosis shadow layer that disappears is that the pencil hardness degree is the sclerosis of the 1 ~ 2H shadow layer that disappears.
The disappear refraction coefficient of shadow layer of above-mentioned capacitive touch screen transparent hardened film, described sclerosis is 1.65 ~ 1.70 the sclerosis shadow layer that disappears.
Above-mentioned capacitive touch screen transparent hardened film, described pre-priming operation are that refraction coefficient is 1.60 ~ 1.65 polyester resin layer, urethane resin layer, polyacrylic resin layer or their mixture resin layer.
Above-mentioned capacitive touch screen transparent hardened film, the thickness of described two pre-priming operations is identical or different.
Above-mentioned capacitive touch screen transparent hardened film, the transparent hard layer that described transparent hard layer is hardness 2 ~ 3H.
Compared with prior art, the utlity model has following advantage:
1. apply the shadow layer that disappears by the surface at hardened layer, solved preferably " shadow " phenomenon of capacitance plate conducting film, improve the display effect of touch screen, prevented that simultaneously the mylar small molecular from separating out the mist degree that causes and going up, guaranteed the transparency of hardened layer.
2. disappear in the utility model refraction coefficient of shadow layer and the refraction coefficient of other each layers of cured film is close, interface phase and boundary reflection between each layer have been eliminated, solved because the reflection of light at different interfaces produces and interfered the line phenomenon, finally alleviate and eliminated " shadow " phenomenon of capacitance plate conducting film, improved the visuality of touch-screen.
