Background technology
Monolithic capacitive touch screen generally comprises transparent glass substrate and sensor circuit layer, sensor circuit layer is produced on the inner side of transparent glass substrate, the outside of transparent glass substrate is then exposed glass surface, in general, glass surface in use, easily grind by the ubiquitous quartz particles of nature (as the grains of sand) flower, glass surface is thickened, has influence on the use of touch-screen.
At present, although there is people to propose sapphire substrate to replace transparent glass substrate, to address this is that, but sapphire substrate too expensive, it is also unfavorable for popularizing.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of monolithic capacitive touch screen with hard coat, and the skin hardness of this monolithic capacitive touch screen with hard coat is higher, be difficult to be scratched, and price is lower.The technical scheme adopted is as follows:
With a monolithic capacitive touch screen for hard coat, comprise transparency carrier and sensor circuit layer, sensor circuit layer is arranged on transparency carrier medial surface, it is characterized in that: also comprise hard films, and hard films covers on the lateral surface of described transparency carrier; Hard films is made up of the higher first kind film of at least one deck refractive index and Equations of The Second Kind film that at least one deck refractive index is lower, and at least one of them has the Moh's scale number higher than 7 for first kind film and Equations of The Second Kind film.
Owing to covering one deck hard films on the lateral surface of transparency carrier, and its hardness number is set to higher than 7, there is higher hardness, can not grind by quartz particles flower, scratch, price is low more than sapphire substrate, and first kind film in hard films, Equations of The Second Kind film also form optics antireflective film, make hard films can not cause the increase of touch-screen reflected light.
As preferred version of the present utility model, described first kind film and Equations of The Second Kind film alternately stacked.First kind film and Equations of The Second Kind film alternately stacked, make each rete be all an antireflective film, its combination after there is better anti-reflection effect.
As the further preferred version of the utility model, the refractive index of described first kind film and Equations of The Second Kind film is greater than 0.2.The refractive index of first kind film and Equations of The Second Kind film is greater than 0.2, and the reflection between rete is increased, and strengthens its anti-reflective effect further.
As preferred version of the present utility model, the outermost layer of described hard films is Equations of The Second Kind film, and Equations of The Second Kind film is the one in pellumina, carbonization boron film, silicon carbide film, boron nitride film, silicon nitride film, phosphatization boron film, phosphatization silicon fiml or borosilicate alloy film.These retes are all better transparent and that hardness is higher film.
As the further preferred version of the utility model, described Equations of The Second Kind film is phosphatization silicon fiml.
As the further preferred version of the utility model, described Equations of The Second Kind film is silicon nitride film.
As preferred version of the present utility model, described first kind film is silicon oxide film.
As preferred version of the present utility model, the optical thickness of described first kind film, Equations of The Second Kind film is that d, d are in the interval of d1 ~ d2, wherein d1=95nm, d2=200nm.Can ensure to have and good subtract effect.
As the further preferred version of the utility model, total number of plies of described first kind film, Equations of The Second Kind film is 4 ~ 9 layers.By total number of plies is set as 4 ~ 9 layers, it not only can ensure that overall rete has good combination anti-reflective effect, and thinner thickness, overall transmitance is also larger.
As the utility model further preferred version, the optical thickness of described first kind film, each layer of Equations of The Second Kind film is evenly distributed in the interval of d1 ~ d2.Thus, every skim is all responsible for a range of wavelengths, after its entire combination, can reach the full wave anti-reflection of visible ray.
Compared with prior art, tool has the following advantages the utility model:
Owing to covering one deck hard films on the lateral surface of transparency carrier, and its hardness number is set to higher than 7, there is higher hardness, can not grind by quartz particles flower, scratch, price is low more than sapphire substrate, and first kind film in hard films, Equations of The Second Kind film also form optics antireflective film, make hard films can not cause the increase of touch-screen reflected light.
