Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The embodiment of the present invention provides a kind of polaroid 100, as shown in Figure 1, comprising: the first polarisation film layer 10 and peep-proof film
Layer 20；Peep-proof film layer 20 is set to the light emission side of the first polarisation film layer 10.Peep-proof film layer 20 in certain angular field of view for dropping
The intensity of low emergent light, to reduce visual angle.
Conventional polaroid only serves to form polarised light or detection, the purpose for screening polarised light, itself does not have and receives
The peep-proof function of narrow viewing angle.Conventional polaroid is after being applied to display device, and the visual angle of display device is relative to normal direction
All at 70 ° even 80 ° or more, so that not only the people immediately ahead of display device can see that display device is aobvious in certain distance
The content shown, the content seeing display device and showing that also can be absolutely clear in the people of display device surrounding lead to important content
It is easy to be leaked.
It will be understood by those skilled in the art that since the present invention is to reach peep-proof function by reducing visual angle, such as Fig. 2
(a) shown in, if the visual angle of the display device with conventional polarizers is 0~θ1 (θ1For example, 70 °~80 °), then, such as Fig. 2 (b)
Shown, for polaroid 100 of the invention when being applied to display device, the visual angle of the display device is 0~θ2, θ2< θ1(θ2Such as
It is 30 °~40 °).

The intensity of emergent light is reduced in range, the visual angle of display device can be made to reduce when the polaroid is applied to display device, thus
Play the effect of peep-proof.
Optionally, as shown in figure 3, peep-proof film layer 20 includes that λ/4 compensates film layer 21 and the second polarisation film layer 22.
λ/4 compensates film layer 21 between the first polarisation film layer 10 and the second polarisation film layer 22, the first polarisation film layer 10
Absorption axiss are vertical with the absorption axiss of the second polarisation film layer 22, and λ/4 compensates the optical axis of film layer 21 and the absorption of the first polarisation film layer 10
Axis is in 45 °.
When the absorption axiss of the optical axis of the compensation film layer 21 of λ/4 and the first polarisation film layer 10 are in 45 °, as shown in figure 4, adding in Pang
The north and south pole of Lay ball is the circularly polarized light of standard, is all different ellipse of state in the point in addition to the pole of north and south of Poincare sphere
Circularly polarized light.Based on this, the circularly polarized light of standard can get in direct-view direction, and it is each to obtain state in other view directions
Different elliptically polarized light.
On this basis, when from λ/4 compensate film layer 21 be emitted light after the second polarisation film layer 22, vector can be obtained
Linearly polarized light of different sizes, wherein maximum in the vector for the linearly polarized light that direct-view direction obtains.As a result, due to inclined from second
There is difference in the linearly polarized light intensity that light film layer 22 is emitted, so that the light intensity of other view directions is cut in addition to looking at direction straight
It is weak, thus, it can reach the purpose of peep-proof.
Intuitively to embody polaroid 100 of the invention in direct-view direction, the light intensity of emergent light is different in other view directions,
It can refer to Fig. 5.The consistent linearly polarized light of intensity being emitted from the first polarisation film layer 10 is input to λ/4 and compensates film layer 21, and from λ/4
After compensating the outgoing of film layer 21, circularly polarized light is obtained in direct-view direction, and it is inclined to obtain the different ellipse of state in other view directions
Shake light.On this basis, after circularly polarized light is input to the second polarisation film layer 22 and is emitted from the second polarisation film layer 22, acquisition
The vector of linearly polarized light is maximum；After elliptically polarized light is input to the second polarisation film layer 22 and is emitted from the second polarisation film layer 22,
The vector of the linearly polarized light of acquisition is respectively less than the vector for the linearly polarized light that circularly polarized light obtains after the outgoing of the second polarisation film layer 22.
So that the light intensity of other view directions is weakened in addition to looking at direction straight.
Optionally, as shown in fig. 6, the polaroid 100 further includes being set to the first polarisation film layer 10 far from the second polarisation
First protective film layer 32 of 22 side of film layer, the first adhesive layer for bonding the first protective film layer 32 and the first polarisation film layer 10
31, pressure-sensitive adhesive layer 33 and release film layer 34 of first protective film layer 32 far from 10 side of the first polarisation film layer are set to.It is pressure-sensitive
Glue-line 33 is used for after release film layer 34 removes, and is bonded with display panel.In addition, the polaroid 100 further includes being set in turn in
Second adhesive layer 35 and second protective film layer 36 of the second polarisation film layer 22 far from 10 side of the first polarisation film layer.
It should be noted that if λ/4 compensate film layer 21 can not directly be bonded with the first polarisation film layer 10, can by
λ/4, which is compensated, is arranged adhesive layer bond the two between film layer 21 and the first polarisation film layer 10.Similarly, if λ/4 compensates film layer
21 can not directly bond with the second polarisation film layer 22, then can be set between film layer 21 and the second polarisation film layer 22 by compensating in λ/4
Adhesive layer is set bond the two.
The embodiment of the present invention also provides a kind of display module, as shown in fig. 7, comprises liquid crystal display panel 200 and setting
In the upper polaroid 300 of 200 light emission side of liquid crystal display panel, which is above-mentioned polaroid 100.Due to upper
It is integrated with peep-proof film layer 20 in polaroid 300, thus the visual angle of display device can be made to reduce, so that the display module has
Peep-proof function.
Optionally, as shown in fig. 7, the display module further include be set to 200 incident side of liquid crystal display panel it is lower partially
Mating plate 400；Down polaroid 400 includes third polarisation film layer, and first is inclined in the absorption axiss and upper polaroid 300 of third polarisation film layer
The absorption axiss of light film layer 10 are vertical.
Further alternative, the absorption axiss of the first polarisation film layer 10 are 135 °, and the absorption axiss of third polarisation film layer are 45 °.
On this basis, in the case where upper polaroid 300 includes that λ/4 compensates film layer 21 and the second polarisation film layer 22, λ/4 compensates film layer
21 optical axis is 0 °.
Compensating the light that film layer 21 is emitted from λ/4 can be circularly polarized light in viewing area (area AA), in AA as shown in Fig. 8 (a)
Area periphery is all the different elliptically polarized light of state.It is incident to the second polarisation film layer 22 when compensating the light that film layer 21 is emitted from λ/4,
And the view directions after the second polarisation film layer 22, as shown in Fig. 8 (b), in the vertical area AA, that is, in direct-view direction, linear polarization
The vector of light is maximum, thus looking at direction straight is the optimal direction of visual effect.The view in the left and right sides area Kan Xiang AA in the area Cong AA
The vector of angular direction, linearly polarized light is minimum, thus, the view directions at left and right sides of the area AA are can not apparent direction.The area Cong AA
The area Kan Xiang AA of two sides up and down view directions, the vector of the linearly polarized light of the relatively straight apparent direction of the vector of linearly polarized light under
Drop, thus, the view directions of two sides are the bad direction of visual effect above and below the area AA.It should be noted that dotted line side in Fig. 8 (b)
To the optical axis direction for compensating film layer 21 for λ/4.
With the absorption axiss of third polarisation film layer in down polaroid 400 for 45 °, the first polarisation film layer 10 in upper polaroid 300
Absorption axiss be 135 °, to compensate the optical axis of film layer 21 be 0 ° to λ/4, and it is aobvious to be arranged in pairs or groups by the down polaroid 400 and upper polaroid 300
