Referring to figure 5 and figure 6, Fig. 5 be in Fig. 2 B-B ' to another sectional view, be at this time second the first shape of liquid crystal molecule
State, Fig. 6 be in Fig. 2 B-B ' to another sectional view, be at this time second the second state of liquid crystal molecule.
Light regulating course 5 include first electrode layer 52 and the second electrode lay 53 and be folded in the first electrode layer 52 with
The second liquid crystal molecule 54 between the second electrode lay 53；
When carrying out fingerprint recognition, the voltage difference between first electrode layer 52 and the second electrode lay 53 forms the second liquid of driving
The electric field that brilliant molecule 54 deflects, for adjusting the rotation angle formation lenticule 51 of the second liquid crystal molecule 54, lenticule 51 and the
One opening is correspondingly arranged.
First electrode layer 52 can be common electrode layer, and the second electrode lay 53 can be pixel electrode layer.
In Fig. 5, voltage is not provided to first electrode layer 52 and the second electrode lay 53, so electric field is not formed at this time, the
Two liquid crystal molecules 54 do not deflect, and the second liquid crystal molecule 52 is in first state at this time, do not carry out fingerprint recognition.It is right in Fig. 6
First electrode layer 52 and the second electrode lay 53 provide voltage, and the voltage difference between first electrode layer 52 and the second electrode lay 53 is formed
The electric field for driving the second liquid crystal molecule 54 to deflect, the second liquid crystal molecule 54 deflect, and form lenticule 51, at this time the second liquid crystal
Molecule 52 is in the second state, can carry out fingerprint recognition at this time.Lenticule 51 can will be from light regulating course 5 far from first substrate
The light that 11 sides enter light regulating course 5 is converged to the first opening 41.
It is appreciated of course that array substrate 2 includes the second substrate 21 in the present embodiment, the second substrate 21 is close to color film

The finger print information interfered then cannot reach light sensitive component by the blocking of black matrix 4, reduce interference and improve fingerprint recognition essence
Degree；What needs to be explained here is that production collimating aperture is not needed yet since lenticule 51 can be such that light converges to the first opening 41, and
Production collimating aperture needs to increase corresponding film layer, and the present invention reduces processing procedures.
Include multiple second electrodes 531 in the second electrode lay 53 with continued reference to Fig. 6, between adjacent second electrode 531 between
Away from the spacing being greater than between adjacent pixel electrodes 7.
Spacing in Fig. 6 between adjacent second electrode 531 is a, and the spacing between adjacent pixel electrodes 7 is b, a > b.It can be with
Understand, when not providing voltage to the second electrode lay 53 and first electrode layer 52, then the second liquid crystal molecule 54 does not occur
Deflection, so light regulating course 5 will not influence the normal display of display panel when not carrying out fingerprint recognition.Due to adjacent second
Spacing between electrode 531 is bigger, orthographic projection of the lenticule 51 that the deflection of the second liquid crystal molecule 54 generates in the second substrate 21
Also bigger, the spacing between adjacent second electrode 531 is smaller, and the lenticule 51 that the deflection of the second liquid crystal molecule 54 generates is second
Orthographic projection on substrate 21 is also just smaller.Between the spacing between adjacent second electrode 531 is greater than between adjacent pixel electrodes 7
Away from when, orthographic projection of the lenticule 51 in the second substrate 21 that the deflection of the second liquid crystal molecule 54 generates is bigger, is carrying out fingerprint
The light flux ratio that can be converged when identification is larger, that is, the fingerprint that can be identified is bigger, can recognize that complete fingerprint
Information.
With continued reference to Fig. 6.Lenticule 51 is adjacent thereto at least one in the orthographic projection of 21 place plane of the second substrate
Second opening 42 has overlapping in the orthographic projection of 21 place plane of the second substrate.
The orthographic projection that lenticule 51 is shown in Fig. 6 in 21 place plane of the second substrate is opened with multiple adjacent thereto second
Mouth 42 has overlapping in the orthographic projection of 21 place plane of the second substrate.
It is understood that voltage ought not provided to the second electrode lay 53 and first electrode layer 52, do not exist between the two
When electric field, then the second liquid crystal molecule 54 does not deflect, the second liquid crystal molecule does not form lenticule in the display stage, only into
Row fingerprint recognition deflects to form lenticule, so the lenticule 51 generated by the deflection of the second liquid crystal molecule 54 is in the second substrate
When orthographic projection on 21 is bigger, the normal display of display panel will not be influenced.Lenticule 51 is put down where the second substrate 21
The orthographic projection in face have at least one second opening 42 adjacent thereto in the orthographic projection of 21 place plane of the second substrate it is overlapping, then

For light regulating course 5 close to the distance between the side of first surface 81, n2 is side and light of the light regulating course 5 close to light sensitive component 6
The refractive index of film layer between sensing unit 6, v be light regulating course 5 between the side and light sensitive component 6 of light sensitive component 6 away from
From n is the refractive index of light regulating course 5, and r1 is radius of curvature of the light regulating course 5 close to 8 side of cover board, and r2 is that light regulating course 5 leans on
The radius of curvature of 6 side of dipped beam sensing unit, the steeper radius of curvature of the curved radian of curved surface is smaller, curved surface more smooth curvature radius more
Greatly, when tending to is plane, radius of curvature tends to infinitely great.
