Optionally, the supporting element 440 includes two brackets, and the fixed structure is to prolong along described two bracket inner sidewalls
The lug boss of stretching, such as shown in Fig. 4 and Fig. 5.But the application is not limited to this, which is also possible in two branch
The step structure etc. being arranged on frame.
Wherein, the optics collimator 410 can be fixed on the upper surface or lower surface of the lug boss.Such as Fig. 4
Shown, which is pasted onto the upper surface of the lug boss；In another example the optics collimator 410 is pasted shown in Fig. 8
In the lower surface of the lug boss.Wherein, it can be opaque for pasting the adhesives of the optics collimator 410 and the lug boss
Adhesive material, such as opaque glue film or glue etc..
The height of the lug boss extended along two 440 inner sidewalls of bracket needs to consider the imaging of the optics collimator 410
Parameter.The optics collimator 410 is the image distance P of the optics collimator 410 at a distance from display screen, should be in certain range
It is interior；The optics collimator 410 is the image distance Q of the optics collimator 410 at a distance from optical fingerprint sensor 420, it should also
In a certain range.Therefore, the total height of the bracket 440 and position height of the lug boss on the bracket 440, it should so that
After optics collimator 410 is fixed on the upper surface or lower surface of the lug boss, between the optics collimator 410 and display screen
The distance between distance and the optics collimator 410 and optical fingerprint sensor 420 are in corresponding range.
Optics collimator 410 in the embodiment of the present application for example can be silicon wafer or high light transmission with through-hole array
The hybrid combining of the glass of rate and low-transmittance material, for example, shown in Fig. 6, in the hole array include it is multiple have regular aperture and
The loophole of pitch of holes, the loophole 610 can have high transmittance to the light that the finger of fingerprint collecting overlying regions reflects
It is greater than 95%, other non-transparent regions 620 then there is high-absorbility for example to meet T=I the lightt/I0≤ 5% (It
For transmitted light, I0For incident light).The loophole 610 or solid hole may be hollow through-hole.The optics collimator
410 are mainly used for that the fingerprint detection light propagated downwards is collimated, modulated and is imaged, and realization will be reflected back from finger surface
The reflected light come is directed to the sensing unit of optical fingerprint sensor 420 to carry out optical detection to obtain fingerprint image letter
Breath, and the light for being unsatisfactory for incident angle requirement is filtered, such as be greater than the light of α in Fig. 7 with aperture axial direction angle
Line.Wherein, the ratio of the thickness T of the aperture D and optics collimator 410 of single hole for example can be in 1:30 between 1:5.It should
The arrangement angle of loophole on optics collimator 410 is matched with the arragement direction of the selfluminous cell on self light emitting display panel.
Optionally, which further includes the optically filtering that 420 top of optical fingerprint sensor is arranged in
Device 430, wherein when the optics collimator 410 is fixed on the upper surface of the lug boss, it is convex which is fixed on this
The lower surface in the portion of rising, alternatively, the upper surface of the optical fingerprint sensor 420 is arranged in the optical filter 430；Alternatively,
When the optics collimator 410 is fixed on the lower surface of the lug boss, which is fixed on the lug boss
Upper surface, alternatively, the upper surface of the optical fingerprint sensor 420 is arranged in the optical filter 430.
The optical filter 430 (or being filter plate etc.) in the embodiment of the present application has height to the light of specific band
Transmitance, and do not have high transmittance then to its all band.The substrate of the optical filter 430 for example can be smalt or
The high transparency material such as blue crystal is plated respectively in the upper and lower surfaces of substrate with specific materials, the number of plies and thickness
Film is filtered to by the light of the optical filter 430 to realize, has the function that wavelength selection.
Any position between display screen and optical fingerprint sensor 420 can be set in the optical filter 430.
Such as shown in Fig. 4, optics collimator 410 is pasted onto the upper surface of lug boss, and the optical filter 430 is pasted onto
The lower surface of lug boss.In another example shown in Fig. 5, optics collimator 410 is pasted onto the upper surface of lug boss, and the optical filter
430 are pasted onto the upper surface of optical fingerprint sensor 420.At this moment, the optical signal of finger reflection first passes through optics collimator 410
It is guided to the sensing unit of optical fingerprint sensor 420 after modulation, and is passed through before light reaches optical fingerprint sensor 420
Optical filter 430 is crossed to be filtered.
Certainly, in the embodiment of the present application, optics collimator 410 and optical filter 430 are arranged at display screen and optics
Between fingerprint sensor 420, but optics collimator 410 and the distance between display screen and optical fingerprint sensor 420 should
It meets certain requirements, and any position between display screen and optical fingerprint sensor 420 can be set in optical filter 430
It sets.Therefore, in addition to the structure of Fig. 4 and fingerprint identification device shown in fig. 5, optics collimator 410 and optical filter 430 may be used also
To there is other arrangements, as long as meeting above-mentioned required distance.Such as shown in Fig. 8, optics collimator 410 is pasted onto lug boss
Lower surface, and the optical filter 430 is pasted onto the upper surface of lug boss.In another example optics collimator 410 is pasted shown in Fig. 9
In the upper surface of optical fingerprint sensor 420, and optical filter 430 is pasted onto the upper surface of lug boss.At this moment, finger reflects
Optical signal first pass through optical filter 430 and be filtered, the light positioned at specific band obtained after filtering is using optics
It is directed to after the modulation of collimator 410 on the sensing unit of optical fingerprint sensor 420.
Fig. 4 is between each optical component into Fig. 9, when the transmission region of fingerprint identification device is pasted, pastes
Material is transparent, to avoid blocking the transmission for the optical signal for carrying finger print information；And in the non-transparent of fingerprint identification device
Region is when being pasted, adhesive material be it is opaque, bring interference to avoid to the optical signal.
For example, when the optical filter 430 is fixed on the upper surface or lower surface of the lug boss, edge it is non-transparent
Region is pasted onto the upper surface or lower surface of the lug boss by the such as opaque glue of opaque adhesive material or glue film etc..
And when the optical filter 430 setting is square on the optical sensor, need using transparent adhesive material such as transparent glue or
