Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
A kind of antireflective flexible cover plate, comprising: flexible base board, antireflection layer and luminous ink layer, the antireflection layer are set
It sets on the flexible base board surface, side of the antireflection layer far from the flexible base board is arranged in the luminous ink layer.
In order to further increase the transmitance of flexible cover plate, to reduce the reflection on flexible cover plate surface.Currently, people are most
The reflectivity on flexible base board surface is reduced using the method for being coated with antireflection layer on flexible substrates.But at present in flexible base board
The maximum reflectivity for for example, antireflection layer of titanium oxide and silica membrane alternating deposit that surface plating is set can only achieve down
Drop to 2%, it is difficult to be preferably minimized the reflectivity of flexible cover plate.For this purpose, inventor largely grinds the structure of antireflection layer
Study carefully test, it is final to determine along the direction of the flexible base board, the antireflection layer by stack gradually zirconium oxide film layer,
First membranous layer of silicon oxide, the first niobium pentaoxide film layer, the second membranous layer of silicon oxide, the second niobium pentaoxide film layer, third oxidation
Silicon film, third niobium pentaoxide film layer and the 4th membranous layer of silicon oxide composition；The zirconium oxide film layer, the first membranous layer of silicon oxide,
First niobium pentaoxide film layer, the second membranous layer of silicon oxide, the second niobium pentaoxide film layer, third membranous layer of silicon oxide, the three or five oxygen
Change two niobium film layers and the 4th membranous layer of silicon oxide thickness be respectively 2-20nm, 10-30nm, 5-20nm, 10-30nm, 30-60nm,
5-20nm、20-40nm、80-120nm。
By this set, transmissivity of the flexible cover plate in visible-range is greater than 99%, in visible-range
Interior reflectivity is less than 1%, even if user uses electronic product under strong light, screen is still clear, and will not influence normally makes
With.
The antireflection layer can be by the method for vacuum deposition, especially electron beam evaporation plating or magnetron sputtering, in flexibility
Plated film forms on substrate, but not limited to this.
In the utility model, what is contacted in antireflection layer with flexible base board is zirconium oxide film layer, compared to other materials
The toughness of inorganic thin film, zirconium oxide film layer is good, while refractive index can achieve 2.0 or more, with membranous layer of silicon oxide and five oxygen
Good anti-reflection effect can be obtained by changing in the case that two niobium film layers are suitably arranged in pairs or groups.
The luminous ink layer hollow out forms LOGO.The flexible cover plate of the utility model includes luminous ink layer, the night
Gloss oil layer of ink hollow out forms LOGO, can reinforce user in night self-luminescence to the memory of LOGO, make it have new
Clever, unique, eye-catching, beautiful visual impact, increases the brand effect of LOGO.
It should be noted that the surface of the flexible base board have visible area and be surrounded on the non-of the visible area can
Viewed area, the luminous ink layer are located at the non-visible area domain.
The utility model is not particularly limited the material of luminous ink layer, can use the conventional material in this field,
Preferably, the material of the luminous ink layer is SrAl2O4:Eu2+, Dy3+.
The flexible base board can be traditional clarity plastic layer.The clarity plastic layer can be poly terephthalic acid second
Diol ester (Polyethylene terephthalate, PET) layer, polyimides (Polyimide, PI) layer, polycarbonate
(Polycarbonate, PC) layer, polymethyl methacrylate (PolymethylMethacrylate, PMMA) layer, optics modeling
Expect (Cyclo-olefin polymer, COP) layer or cyclic olefine copolymer (copolymers of cycloolefin, COC)
Layer.
But flexible base board use traditional clarity plastic layer when, cannot be to electronics since the hardness of transparent plastic is inadequate
Product plays a very good protection, and the scratch resistance of transparent plastic is bad, is easy to be scratched.
For this purpose, the utility model is further improved, the flexible base board include the flexible glass layer being stacked and
Clarity plastic layer.
Wherein, the flexible glass layer and the clarity plastic layer are linked together by bonding, it is preferable that described soft
Property glassy layer and the clarity plastic layer are linked together by optical clear bonding agent.It should be appreciated that the utility model can
To choose the different-thickness of bonding agent according to different application scenarios, as long as selected bonding agent thickness can guarantee flexibility
The adhesive strength of glassy layer and clarity plastic layer, the utility model for bonding agent thickness without limitation.
The flexible glass layer can be ultra-thin glass, ultra-thin glass with a thickness of 10-50 microns.Ultra-thin glass has glass
The rigidity characteristics of glass material, and also take into account certain bendable folding endurance.
In the utility model, is designed by the composite laminate of flexible glass layer and clarity plastic layer, utilize glass material
Rigidity characteristics can guarantee the hardness of flexible cover plate, and flexible cover plate can play the work of the protection to electronic product under external impacts
With so that flexible cover plate has preferable scratch resistance performance.The bent of flexible cover plate can be improved using the flexible characteristic of plastics
Property, so that electronic product realizes better bendable folding endurance, and plastics can also discharge part by deformation under external impacts
External force improves the bendable folding endurance of flexible cover plate to reduce impact of the external force to flexible cover plate, at the same flexible glass layer because by
Powerful external force and after breakage, the fragment of flexible glass layer can be adhered on clarity plastic layer, prevent being scattered for fragment.
Good bendable folding endurance, the transparency, enough intensity and strong bendable can be provided simultaneously with using the flexible base board
Folding endurance etc..
As a further improvement, further including anti-peeping layer, the anti-peeping layer is set to the antireflection layer and luminous ink
Between.The anti-peeping layer makes the content that only just can see that display screen in the certain angle in display device front, for protecting
The content of shield display device is peeped from other people.It should be noted that anti-peeping layer uses ultra tiny shutter optical principle skill
The anti-peeping film of art production, user can read from 30 degree of front visual angle, and can only see pitch-dark picture from two sides, and then reach
The purpose for preventing people from side from peeping protects privacy of user and secret.Ultra tiny shutter optical principle technology is prior art,
This is no longer described in detail.
The above-mentioned embodiments merely express the embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
Therefore it cannot be interpreted as that a limitation on the scope of the patent of the present invention, as long as using the form institute of equivalent substitution or equivalent transformation
The technical solution of acquisition, shall fall within the scope of the present invention.
