Fig. 1 is the present invention's infrared composite transparent sheet preferred embodiment schematic diagram;
Fig. 2 is the schematic diagram of another embodiment of the infrared composite transparent sheet of the present invention.
Fig. 3 is the transmission measurement figure of the infrared composite transparent sheet shown in Fig. 2.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, a preferred embodiment of the present invention provides a kind of infrared composite transparent sheet 10, and it comprises tempered glass layer 11, infrared light transmission ink layer 13 and infrared light transmission rete 15.Described tempered glass layer 11, infrared light transmission ink layer 13 and infrared light transmission rete 15 superpose setting successively, and described infrared light transmission ink layer 13 by silk-printing and shaping on described tempered glass layer 11, described infrared light transmission rete 15 is formed on described infrared light transmission ink layer 13 by the mode of vacuum coating.Described vacuum coating mode comprises: magnetron sputtering method, electron-beam vapor deposition method etc.Wherein, about film material, the present invention is not as limit.
In this example, described tempered glass layer 11 is mainly chemically reinforced glass.Described infrared light transmission ink layer 13 is that infrared light transmission ink is formed on tempered glass 11 in the mode of silk-screen.Described infrared light transmission ink film thickness is 3-7 μm.Be preferably 4 μm, infrared light transmission ink layer 13 ink to infrared light through and better to the cut-off effect of visible ray.Described infrared light transmission rete 15 is formed by the mode alternating deposit of vacuum evaporation by titanium dioxide layer and silicon dioxide layer.When described infrared light transmission rete 15 forms on described infrared light transmission ink layer 13, the titanium dioxide layer of described infrared light transmission rete 15 contacts with described infrared light transmission ink layer 13.Described infrared light transmission rete 15 is multilayer, is chosen as 30-40 layer.Infrared composite transparent sheet 10 in this example can be used on the devices such as the less screen of size.
Infrared composite transparent sheet of the present invention directly by described infrared light transmission ink layer 13 silk-screen on described tempered glass layer 11, do not need one deck glassy layer of fitting again, bubble is avoided to produce, not only ensure the high permeability of infrared light, and reduce the thickness of infrared composite transparent sheet, coordinate with described infrared light transmission rete 15 that visible light transmissivity can be made to drop to is minimum simultaneously, and then improve the functional of described infrared composite transparent sheet.
Refer to Fig. 2, in another embodiment of the present invention, be with above-described embodiment difference, described infrared composite transparent sheet 20 also comprises optical clear glue-line 21 and transparent flexible base material 22.Described tempered glass layer 11, infrared light transmission ink layer 13, optical clear glue-line 21, infrared light transmission rete 15 transparent flexible base material 22 superpose setting successively, described infrared light transmission rete 15 is formed on described transparent flexible base material 22 by the mode of vacuum coating, and described infrared light transmission ink layer 13 by silk-printing and shaping on described tempered glass layer 11, described transparent flexible base material 22 is affixed on described infrared light transmission rete 15 by described optical clear glue-line 21.Can avoid that infrared light transmission rete 15 is naked to be exposed on the external like this, thus can prevent from, in follow-up assembly technology, causing the scraping to infrared light transmission rete 15, and transparent flexible base material 22 can play the effect of protective film.
In the present embodiment, after infrared light transmission flexible membrane material can pass through to be coated with infrared light transmission rete 15 on large stretch of transparent flexible base material 22, cut out as multiple fraction according to described infrared light transmission ink layer 13 area, and get monolithic infrared light transmission flexible membrane material and fit on described infrared light transmission ink layer 13.Described transparent flexible base material 22 is preferably polyethylene terephthalate.Described optical clear glue-line is OCA (OpticallyClearAdhesive) optical cement.Refer to Fig. 3, from curve in figure, the mean transmissivity of infrared light reaches more than 90%, and visible light part ends substantially completely, so can ensure the stability of infrared composite transparent sheet.
The present invention also provides a kind of touch-screen, and described touch-screen is the electronic device touch control screens such as panel computer, and it has body sense recognition system.Touch-screen to comprise in touch-screen module (not shown) and above-mentioned two embodiments any one infrared composite transparent sheet, and described infrared composite transparent sheet is installed on touch-screen module.Because described infrared light transmission ink layer 13 and infrared light transmission rete 15 are directly compound on described tempered glass layer 11 by described infrared composite transparent sheet, do not need one deck glassy layer of fitting again, not only ensure the high permeability of infrared light, and reduce the thickness of infrared composite transparent sheet, and then reduce the thickness of touch screen, simultaneously, appearance color due to infrared light transmission ink layer is black, is thus easy to do hiding process to the body sense recognition means of infrared light transmission sheet and inside in the dark border of cover-plate glass.
Above-described embodiment, does not form the restriction to this technical scheme protection domain.The amendment done within any spirit at above-mentioned embodiment and principle, equivalently to replace and improvement etc., within the protection domain that all should be included in this technical scheme.
