It extracts useful optical signalling and has very high degree of difficulty, technical difficulty grade reaches the degree of intimate single photon image, it is necessary to borrow
Raw video can be parsed according to wave theory of light operation reconstruction by related algorithm.In order to avoid this technological difficulties, it is known can
Light-exposed colorimetric sensor films configuration may require that additional optical enhancement device in former display screen structure, or only that optical sensor is thin
Film configures in display screen side, carries out optical image reconstruction using the light that non-perpendicular reflection reaches side, such as: the Chinese people
Described in republic patent CN101359369B.However although such technology can avoid the technological difficulties of dim light imaging, it is additional
Optical device increases the thickness of light detecting significant screen, and the configuration mode in significant screen side is then unable to satisfy the full frame body of user
It tests.
In short, be limited to the structure of existing display screen, user on terminal display screen touch control component (such as picture,
Video etc.) when being operated, terminal can not synchronous acquisition to the fingerprint of user, it is even more impossible to carry out fingerprint recognition operation.Work as needs
When using finger print identifying, it is still desirable to be acquired again to user fingerprints, complex steps, bring bad experience to user.

As shown in Figure 1, touch display screen includes cover-plate glass, touch screen, self-luminous diode display pixels from top to bottom
Combination can be placed in light detecting array film (i.e. sensing unit) in the lower section of touch display screen, to realize the life to user
Reason feature (such as fingerprint or palm print information) carries out detecting identification.By taking fingerprint recognition as an example, structure shown in FIG. 1 is realizing fingerprint letter
At least there is following problems when breath acquisition: (1) after the display pixel immediately below finger is irradiated to finger, in cover-plate glass
Upper surface can occur light penetrate, the different optical phenomenas such as light reflection and light scattering, the whether burr or dimpled grain of fingerprint,
Really can form that bright, dark effective reflected light signal is very faint, the burr or dimpled grain that distinguish fingerprint are even more to add on difficult
It is difficult；(2) it is limited to the isostructural material of cover-plate glass, touch screen, display screen and relevant thickness, even if reflected light signal is enough strong,
When have passed through cover-plate glass, touch screen, display screen, after reaching light detecting array film, luminous intensity intensity has seriously weakened (logical
Often reduce 95% or more), while in the TFT opening by display screen optical distortion phenomenon, shadow can also occur for reflected light signal
The acquisition of finger print information is rung；(3) its collimation that shines of each display pixel of self-luminous diode (OLED) display screen is low, i.e. light emitting anger
Degree is very wide, these wide-angles, which shine, to be easy to interfere with adjacent or interval the pixel light source fingerprint to be irradiated, and causes to adopt
The finger print information inaccuracy collected.
In order to solve above-mentioned smooth detecting structure when detecting physiological characteristic information, due to entering the anti-of light detecting array film
It is serious to penetrate light signal strength reduction, causing the physiological characteristic information lines captured to be distinguished, unobvious, information collection is inaccurate asks
Topic, the present invention provides it is a kind of it is synchronous verifying finger print information touch control component operating device, described device can be applied to detecting,
Identify physiological characteristic information, such as fingerprint, palmmprint.
As shown in fig. 7, described device includes cover-plate glass, touch screen, self-luminous diode (OLED) display screen 2, light from top to bottom
It learns glue 4, optical device 5, light and detects array film 3；The touch screen fits in the lower surface of cover-plate glass, the optical cement 4
Fit in the lower surface of self-luminous diode (OLED) display screen 2；The refractive index of the optical cement 4 is less than the refractive index of cover-plate glass, institute
Stating self-luminous diode (OLED) display screen includes multiple display pixels.For ease of description, all attached drawings of the invention are by cover-plate glass
It is integrated with touch screen simplification, cover-plate glass/touch screen 1 is denoted as, when describing optical path change, by optical path in cover-plate glass/touching
It touches the variation that 1 surface of screen occurs and is reduced to the variation that optical path is occurred in cover-plate glass surface.
When the lower section by light detecting array film configuration in display screen structure, by single display pixel or display pixel
Array (can be a row or column display pixel, be also possible to multiple display pictures of cyclically-varying or aperiodic variation arrangement
Element) be irradiated to the fingerprint above cover-plate glass as light source after, light will reflect.Due to being irradiated to the light of fingerprint ridge
It is most of to be absorbed by burr skin, and the air gap between dimpled grain and cover-plate glass can allow the light portion for being irradiated to dimpled grain
Reflection, therefore the light sensitive pixels of light detecting array film can receive bright, the dark feature of difference of fingerprint concave, convex line, light detecting
The bright dark feature reconstruction that array film can be shown according to reflected light signal goes out the burr and dimpled grain image of fingerprint.
Referring to Fig. 2, it is as its name suggests by self-luminous two that display screen of the invention, which is self-luminous diode (OLED) display screen,
Display screen composed by pole pipe pixel array, such as Organic Light Emitting Diode (OLED) display screen, micro- light emitting diode (micro-
LED) display screen etc..The display screen includes MxN display pixel, for the ease of issuing the light of optical signal to each display pixel
Road variation is described in detail, and the display pixel of Nth row m column on display screen is denoted as Pmn by the present invention, other display pixels
Optical path change can similarly obtain.In order to better describe the optical path change of display pixel, spontaneous optical diode of the present invention is aobvious
The thickness of display screen is less than the 1/10 of cover-plate glass thickness, and the refractive index of display screen and cover-plate glass is closer to, thus is counting
When calculating optical path change, reflected light signal can be ignored for the variation that display screen surface occurs is compared to cover-plate glass,
To simplify explanation.
Referring to Fig. 3, the optical path change signal for the single display pixel light emission reflection being related to for one embodiment of the invention
Figure.Top circle indicates that single display pixel Pmn issues the radius of cross section less than R in Fig. 3CLight beam top view, radius
For RCLight correspond to cover-plate glass upper surface incidence angle be θ c, such as the corresponding position of dotted line in Fig. 3.
Since cover-plate glass refractive index n2 is about 1.5, air refraction n1 is about 1.0, therefore when (m, n) is a aobvious
When showing that the light source of pixel is irradiated upwards with wide-angle, cover-plate glass surface incident angle θ is irradiated to greater than θ c (θ c=sin-1
(n1/n2)) light can be totally reflected.Assuming that the projected length that θ c corresponds to circle coordinates r axis is Rc, with described the (m,
N) a light emitting display pixels position Pmn is origin, using Rc as the light outside the circle of dotted line of radius, for can on cover-plate glass table
The light ray that face is totally reflected.When the optical radiation for being greater than θ c in cover-plate glass upper surface incident angle is being contacted with cover board
When the burr of the fingerprint of glass top surface, since the refractive index of burr skin has destroyed the condition of original total reflection, cause
The reflection signal of opposite burr position can not be totally reflected in cover-plate glass, so that part reflected light signal passes through cover board glass
Glass lower surface enters light detecting array film and forms bright rays.Relatively, due to there is sky between the dimpled grain of fingerprint and cover-plate glass
Gas gap, therefore can maintain to be totally reflected for the reflected light signal of dimpled grain position, and light detecting array film can not be arrived at and shape
At dark line.
In short, the incident angle of the i.e. upper surface of cover-plate glass is greater than compared to the light ray within Fig. 3 circle of dotted line
The light ray of θ c can more have the fingerprint dimpled grain region of the air gap as detecting.Therefore under an effective optical profile type display screen
Fingerprint identification technology needs to be gone to irradiate with the combination of effective irradiation or be scanned on cover-plate glass using Rc as characteristic size
Finger position can just obtain the sensitive echo area of height for fingermark image.Assuming that touch cover-plate glass with a thickness of h, then Rc=
h·tan-1(θc)。
When the light beam that the light source of (m, n) a display pixel on display screen issues is irradiated upwards with wide-angle, although
The incident angle θ for being irradiated to the upper surface of cover-plate glass is greater than the ray (θ c=sin-1 (n1/n2)) of θ c, across air between pair
The fingerprint dimpled grain in gap, which has, to be more accurately totally reflected, however is irradiated to the excessive incident angle of cover-plate glass surface, is all-trans
The light transmission path for being emitted back towards light detecting array film is also increasingly longer, this will lead to useful optical image information and also decays more
Add it is serious, when this part of reflected light signal reaches light detecting array film, it has also become without can refer to making an uproar for value
Acoustic jamming.When therefore being also required to define (m, n) a display pixel as fingerprint of the light source irradiation above cover-plate glass,
The light reconnaissance range of maximum available information.
Fig. 4 and Fig. 5 are please referred to, since the refractive index of the refractive index (n3) of optical cement is less than the refractive index of cover-plate glass
(n2), therefore the first total reflection (hereinafter referred to as " total reflection 1 ") occurs in the upper surface of cover-plate glass and enters optical cement surface
In light ray, on optical cement surface the second total reflection (hereinafter referred to as " total reflection can occur for ray of the incident angle φ greater than φ c
2 "), φ c=sin-1 (n3/n2).Assuming that the projected length that φ c corresponds to circle coordinates r axis is Rc '=htan-1 (φ c), In
Light outside using (m, n) a display pixel position Pmn as origin, the circle of dotted line that 2Rc ' is radius, as can be in light
Learn the light ray that total reflection 2 occurs for glue surface.And for that the light ray of total reflection 2 can occur on optical cement surface, compared to
For taking 2Rc ' as the light ray within the circle of dotted line of radius, since reflected light signal path is too long, without having
The light ray of high-precision finger print information, therefore the optical cement for being refracted rate n3 < n2 is filtered out in a manner of being totally reflected 2.
Complex chart 4 and Fig. 5 it is found that for single display pixel, can occur in the light beam that goes out total reflection 1 with it is complete
The light beam of reflection 2, is to have the corresponding optical signal of degree of precision finger print information.On this basis, it can define and realize screen
When lower fingerprint identification technology, after irradiating fingerprint using (m, n) a display pixel of self-luminous diode (OLED) display screen as light source, light
Detecting array film can collect relative sensitive and effective finger-print region, be with a display pixel position (m, n)
Pmn is origin, Rc to the dashed concentric annular shape band beam area that 2Rc ' range is radius, if projecting to the direction circle coordinates r,
It is Rc < r < 2Rc ' regional scope, as light detecting array film can be from the single display picture of self-luminous diode (OLED) display screen
The most suitable fingerprint optical information obtained in the light source that element issues, it is specific as shown in Figure 6.
For being greater than the light ray other than the region 2Rc ', as previously mentioned, can be carried out using the optical cement of respective indices of refraction
Filtering, i.e., so that the light ray being greater than other than the region 2Rc ' is totally reflected on optical cement surface, without entering light detecting
In array film, and then influence the acquisition of finger print information image.And the light ray for being less than the region Rc, the present invention is to pass through
The mode that optical device is arranged above light detecting array film is filtered.In the present embodiment, the optical device 4 wraps
Include light shading type optical device and phase change formula optical device, the light shading type optical device include periodical pinhole array or
It is aperiodicity pinhole array, the phase change formula optical device includes refractive index in periodically variable photon crystal structure
Or microlens array structure or refractive index are in the diffusing scattering structure of aperiodicity change.
Preferably, the shape of the pin hole can be circular hole or square hole, and optical device can pass through code aperture (coded
Aperture compression sampling method) obtains, and by taking fingerprint recognition as an example, finger print information identification only needs answering for bright, dark two grayscale
With requiring, (in the present embodiment, specifically needs to filter display pixel and be irradiated to cover board by designing spatial frequency filtering
Glass surface θ<the light ray of θ c and θ>φ c), the code aperture of optical device is designed as the device with light-guiding function,
It may be implemented Rc < r < 2Rc ' high-resolution region is bright, half-light signal acquisition, and make the reflected light by optical device
