Detailed Description
The core of the utility model is to provide an electronic product and transparent cover plate can avoid the bacterium to stain the surface, avoids the electronic product to propagate the bacterium to the user, avoids causing adverse effect to the user health, promotes user's standard of living.
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
An embodiment of a transparent cover plate provided by the present application is shown in fig. 1, and fig. 1 is a schematic view of a transparent cover plate provided by the present application, the transparent cover plate includes a transparent substrate 1, an optical matching layer 2 is disposed on one surface of the transparent substrate 1, and a nano-antibacterial film layer 3 is disposed on a surface of the optical matching layer 2.
It should be noted that, a high refractive index material is used for the general nano-antibacterial film layer 3, and the direct plating on the surface of the transparent substrate 1 may directly affect the chromaticity and the reflectivity of the cover plate, and affect the display effect, so the optical matching layer 2 needs to be further provided to reduce the reflectivity and change the chromaticity, so that the nano-antibacterial film layer 3 does not affect the optical effect of the transparent material or enhance the display effect (such as average transmittance or average reflectivity), and the nano-antibacterial film layer 3 used herein may be an existing material, such as titanium dioxide, which has an antibacterial effect, has a great transparency in the visible wavelength range, belongs to a hard film material, and has relatively small impact on the display effect and the surface hardness.
According to the technical scheme, the transparent cover plate has the advantages that the surface of the transparent substrate is provided with the optical matching layer, the surface of the optical matching layer is provided with the nano antibacterial film layer, so that bacteria can be prevented from being contaminated on the surface, the bacteria can be prevented from being transmitted to a user by an electronic product, adverse effects on the health of the user are avoided, and the living standard of the user is improved.
In a specific embodiment, the nano-antibacterial film layer 3 is a nano-titanium dioxide film layer, that is, nano-titanium dioxide can be used for realizing antibacterial function, and specifically, vacuum can be adoptedThe coating method comprises evaporation plating, sputtering plating and the like, wherein the evaporation plating is to melt titanium dioxide coating material by using an electron gun and then evaporate in a gas molecule mode, the sputtering plating specifically adopts reactive sputtering, Ar particles bombard a Ti target, the Ti target is bombarded and sputtered by Ti atoms, the Ti atoms fly to a substrate to be plated, and then O is introduced into the substrate to be plated2The Ti deposited on the surface of the substrate is oxidized into TiO2Further, titanium dioxide is an anatase type crystal, has a forbidden band width of 3.2eV corresponding to photon energy at a wavelength of 387.5nm, and when light (ultraviolet light) having a wavelength of 387.5nm or less is irradiated, electrons in the valence band of titanium dioxide are excited to the conduction band to form highly active electrons e having a negative charge-While simultaneously generating positively charged holes h in the valence band+H adsorbed on the surface of titanium dioxide2O may be replaced by h+Oxidation to OH, O2Quilt e-Is reduced to，And OH can cause bacterial protein and lipid breakdown, thereby killing bacteria.
Further, the thickness of the nano-antibacterial film layer may preferably be 5nm to 20 nm, and if the film layer is too thin, the current process conditions are difficult to control, and if the film layer is too thick, the optical matching layer is difficult to optimize the effect.
On the basis of the above embodiments, the optical matching layer may preferably be a silicon dioxide film layer, a magnesium fluoride film layer, a silicon dioxide/titanium dioxide film layer, a silicon dioxide/silicon film layer, or a silicon dioxide/niobium pentoxide film layer.

In order to further enhance the hand feeling of the user and improve the user experience, the surface of the nano antibacterial film layer 3 can be provided with a non-compact nano anti-fingerprint layer 4, the property of the nano anti-fingerprint layer 4 is non-compact, the relation with the nano antibacterial film layer 3 is similar to the soil under a lawn and a lawn, so that the antibacterial effect of the nano antibacterial film layer 3 cannot be influenced, and the display cover plate is more suitable for the antibacterial effect.
Further, the thickness of the nano anti-fingerprint layer 4 may preferably be 5nm to 10 nm, if the thickness is greater than 10 nm, the surplus AF material residue is caused, the antibacterial effect is affected, and if the thickness is less than 5nm, the good hydrophobic effect cannot be achieved.
Meanwhile, the nano fingerprint-proof layer 4 may preferably be a perfluorooctyl trichlorosilane layer, and of course, other fluorine-containing low surface energy polymer substances, such as triethoxy-1H, 2H-tridecafluoro-n-octylsilane, etc., may also be selected.
