Description
Technical field
The present invention relates to a kind of glass panels for living body finger print identification, belong to technical field of glass materials.
Background technique
With the development of the times, insecure identification and certification cause the massive losses of business, property etc..
The biological feather recognition method that password can be substituted has become one of the method that can solve very well Verify Your Identity questions, such as sound
The physical features of sound, fingerprint etc. are identified.But there are security risks for this identification device, the second people can get and mould
It imitates corresponding pattern data or dry simply cut physical characteristic part from the first and can disguise oneself as the first.In order to disappear
Except the above adverse conditions, the existing method and apparatus for also thering is research to be used for vivo identification.As transmitted by detection living body
Electromagnetic wave (terahertz waves), the intrinsic information for therefrom extracting living body are compared with the information stored to carry out the knowledge of living body identity
Not；Also the infrared microscopy image information by detecting living body finger print is identified.By using by prism, light source, lens group
The acquisition device that part, imaging sensor are constituted is identified, however, can all use in the general lens assembly using acquisition means
Optical filter (glass panel), and existing optical filter is essentially all the light by infrared band, and cannot be targeted
The infrared band only issued through living body finger print, to influence recognition performance；Meanwhile existing optical filter is using green
The optical filter of color, and be made into golden Shi Zehui and be not achieved and high saturating effect is played to infrared light.As (authorization is public for Chinese patent
Announcement number: a kind of anti-reflection filter piece CN203164459U) is disclosed, including 7 layers on transparent glass substrate and transparent glass substrate
Anti-reflection film, 7 layers of anti-reflection film repeatedly replace heap by the silica coating of low-refraction and the titanium oxide film layer of high refractive index
It is stacked, 7 layers of anti-reflection film are from the inside to the outside successively are as follows: the 1st layer, SiO2Film layer, with a thickness of 175.5-176nm；2nd layer, TiO2Film
Layer, with a thickness of 12.5-12.8nm；3rd layer, SiO2Film layer, with a thickness of 31.5-32nm；4th layer, TiO2Film layer, with a thickness of 68-
68.49nm；5th layer, SiO2Film layer, with a thickness of 4-4.3nm；6th layer, TiO2Film layer, with a thickness of 34-34.4nm；7th layer, SiO2
Film layer, with a thickness of 85.5-86nm.Although it just reaches antireflective effect by the film layer of smaller layers number, however, itself merely to
It realizes to the effective anti-reflection of visible light, and in the visible light wave range of 380nm-700nm, and phase is then not achieved for infrared band
The effect answered.
Summary of the invention
The present invention is directed to the above defect existing in the prior art, provides a kind of glass surface for living body finger print identification

Infrared light wavelength can be realized wavelength in the transmission of 850nm-920nm range wave band between 850nm-920nm, and penetrate
The high effect of rate；It meanwhile being to reflect visible light in IR ink layer by the design main purpose to each film plating layer thickness
After be capable of forming interference effect, to realize that there is golden color effect, meanwhile, to the light transmittance of the infrared light of living body finger print
Reach 98% or more.
In the above-mentioned glass panel for living body finger print identification, preferably, the IR ink layer with a thickness of
5.4nm.By controlling the thickness of ink layer, the effect of reflection is improved, and can guarantee to wavelength in 850nm-920nm range wave
The transmission of section.As a further preference, the IR ink layer is printed using HF1000 series ink or HF1400N series ink
It forms, its ability for reflecting visible light is generally improved using the ink of black, meanwhile, have printing adhesive force high, and can
Improve to wavelength 850nm-920nm range wave band transmitance.
In the above-mentioned glass panel for living body finger print identification, preferably, the living body finger print issued it is red
The outer a length of 850nm-920nm of light wave.This glass panel can realize the wavelength of the wave band and penetrate, and also have high transmittance
Effect.
In the above-mentioned glass panel for living body finger print identification, preferably, the transmitance of the infrared light wavelength
It is 98% or more.By making that there is preferable antireflective effect, so as to reality under the collective effect of cover film and IR ink layer
Now to the wavelength of living body finger print 850nm-920nm through performance；Meanwhile and the transmitance of visible light can be made to control
5% or less.
In the above-mentioned glass panel for living body finger print identification, preferably, the lower surface of the glass substrate is also
It is covered with AF film layer.Anti-fingerprint and antifouling effect can be played, the identification generated by glass panel surface contamination is reduced and misses
Difference improves the sensitive performance of identification.
In conclusion compared with prior art, the present invention having the advantage that
For the glass panel of living body finger print identification, by using TiO2Film and SiO2Film carries out alternate plating, meanwhile, knot
It closes and allows to realize that, to the long effect penetrated of the infrared waves of living body finger print, light transmittance is reached in surface printing IR ink layer
To 98% or more；Meanwhile allow to be formed interference of light effect by the reflex of cover layer and IR ink layer, and by pair
The control of the thickness of each plated film of cover layer makes to produce in golden color aesthetics.
