The thin film layer 32 is provided on the first surface 31 a. That is, the thin film layer 32 may be disposed on either the upper surface of the polarizer 31 or the lower surface of the polarizer 31.
When the thin film layer 32 is disposed on the upper surface of the polarizer 31, the backlight firstly passes through the polarizer 31, the polarization degree of the blue light is low, when the light passes through the thin film layer 32 again, the short-wave polarized light parallel to the length direction of the one-dimensional material is absorbed again, and the normal light of the long-wave band is directly transmitted, so that the polarized light with high polarization degree of the visible light full-band is finally obtained.
When the thin film layer 32 is disposed on the lower surface of the polarizer 31, the backlight passes through the thin film layer 32, the polarized light of the blue light part parallel to the length direction of the one-dimensional nano monomer 321 is absorbed, so that the transmitted blue light part is the polarized light perpendicular to the length direction of the one-dimensional nano monomer 321 and the unpolarized light of the long wavelength band, when the light passes through the polarizer 31 again, the polarized light of the blue wavelength band directly passes through the polarizer 31 because the polarization direction is parallel to the polarization axis 311 of the polarizer 31, and the light of the long wavelength band is screened as the polarized light, so that the polarized light of the visible light with higher full-wavelength band polarization degree is obtained.

It is understood that the film layer 32 may be 15 microns, 20 microns, 25 microns, and the like.

Specifically, the one-dimensional nano-monomer 321 may be a nanorod, a nanowire, or the like. In the embodiment of the present application, the structural form of the one-dimensional nano-monomer 321 is not described in detail. More specifically, the nanorods, nanowires, etc., have a length between 20 nanometers and 200 nanometers.

Referring to fig. 5, fig. 5 is a flowchart illustrating a method for manufacturing a polarizer assembly according to an embodiment of the present disclosure. The embodiment of the application provides a method for manufacturing a polarizer assembly, which comprises the following steps:
101. and attaching the one-dimensional nano monomer to the polyvinyl alcohol film to form the film layer.
The one-dimensional nano-monomer can be formed by mixing any one or more of CdSe, CdS, ZnSe, InP, CsPbCl3, CsPbBr3 and halogen-doped perovskite structures, and the CdSe, the CdS, the ZnSe and the InP all comprise cladding structures. In the embodiment of the present application, which component is specifically used for the one-dimensional nano-monomer is not specifically limited. Specifically, the length of the one-dimensional nano-monomer is between 20 nanometers and 200 nanometers.
Before the one-dimensional nano monomer is attached to the polyvinyl alcohol film to form the film layer, the one-dimensional nano monomer is subjected to quenching treatment. The luminescent one-dimensional nano monomer material can be quenched so that the luminescent one-dimensional nano monomer material does not emit light any more. Therefore, the polarization degree of the whole visible light wave band of the polarizer is further improved.
Specifically, the step of mixing the one-dimensional nano monomer with the polyvinyl alcohol film to form the film layer further comprises the following steps:
1011. and mixing the normal hexane solution of the one-dimensional nano monomer with the pressure-sensitive adhesive to obtain a mixed solution.
The mass concentration of the one-dimensional nano monomer is between 2.5 and 5 percent, so that the one-dimensional nano monomer can not agglomerate and can be smoothly bonded with the polyvinyl alcohol film. And the method is simple and convenient to operate and low in cost.
1012. And coating the mixed solution on a polyvinyl alcohol film to obtain the one-dimensional nano film.
In this way, the one-dimensional nano-monomer can be formed into a film adhered to the polarizer. The one-dimensional nano monomer is conveniently arranged on the polaroid, and the length direction of the one-dimensional nano monomer and the polarization axis direction of the polaroid keep a stable angle. The extinction ratio can be improved after light penetrates through the thin film layer with the one-dimensional nano monomer, and therefore the polarization degree of the whole visible wave band of the polarizer is improved.
1013. And drying the one-dimensional nano film.
And drying the one-dimensional nano film by using drying equipment so that the one-dimensional nano film can be stretched and the one-dimensional nano monomers are arranged at the same angle.
102. And stretching the film layer to enable the length direction of the one-dimensional nano monomer to extend towards the same direction, wherein the one-dimensional nano monomer is used for absorbing the polarized blue light in the same length direction as the one-dimensional nano monomer.
The one-dimensional nano film is stretched by the stretching tool at a stretch ratio of 6 to 8 times, so that the one-dimensional nano film becomes a film layer, specifically, the film layer may be 15 micrometers, 20 micrometers, 25 micrometers, and the like. The thickness of the thin film layer in the embodiment of the application is related to the concentration of the one-dimensional nano monomer.
The thickness of the thin film layer is set to be between 15 micrometers and 25 micrometers in the embodiment of the present application. Therefore, the contrast of the polarizer can be improved, and the whole thickness of the polarizer assembly is not increased too much.
Specifically, in the stretching process, the length direction of the one-dimensional nano monomer is perpendicular to the length direction of the polarizing axis of the polarizer. Because the polarized light of the blue light part parallel to the length direction of the one-dimensional nano monomer is absorbed, the transmitted blue light part is the polarized light vertical to the length direction of the one-dimensional nano monomer and the unpolarized light of the long wave band, when the light transmits through the polarizer, the polarized light of the blue light wave band directly passes through the polarizer because the polarization direction is parallel to the polarization axis of the polarizer, and the light of the long wave band is screened into the polarized light, thereby obtaining the polarized light with higher polarization degree of the visible light full wave band.
In this application embodiment, the thin layer includes a plurality of one-dimensional nanometer monomers, and the free length direction of one-dimensional nanometer extends towards same direction, and the thin layer setting is in the one side of polaroid, and one-dimensional nanometer monomer is used for absorbing the blue light, and this application embodiment adopts this kind of structure can improve the extinction ratio of polaroid blue light wave band, reaches the lower purpose of improvement polaroid blue light wave band polarization degree.
