For example, a polarizer includes a polarizing film layer, a moth-eye film, a first protective layer and a second protective layer, wherein the moth-eye film and the second protective layer are respectively connected to two opposite side surfaces of the polarizing film layer, and the first protective layer is connected to the side surface of the moth-eye film far away from the polarizing film layer. In another example, the polarizer is an upper polarizer.
To further illustrate the polarizer, referring to fig. 2, a polarizer 10 includes a polarizing film layer 100, a moth-eye film 200, a first protective layer 300 and a second protective layer 400, wherein the moth-eye film 200 and the second protective layer 300 are respectively connected to two opposite sides of the polarizing film layer 100, that is, two opposite sides of the polarizing film layer 100 are respectively connected to the moth-eye film 200 and the second protective layer 300, that is, one side of the polarizing film layer 100 is connected to the moth-eye film 200, and the second protective layer is connected to a side of the polarizing film layer 100 away from the moth-eye film 200. The first protective layer 300 is connected to the side of the moth-eye film 200 away from the polarizing film layer 100.
The polarizing film layer, also called pva (polyvinyl alcohol) layer, mainly plays a role of polarizing light; the first protective layer, also called a first tac (triacetyl cellulose) layer, mainly plays a role in supporting and protecting the polarizing film layer, and is used for improving the overall mechanical performance of the polarizer; the second protective layer, also called a second tac (triacetyl cellulose) layer or a second cop (cyclic Olefin polymer) layer, also plays a role in supporting and protecting the polarizing film layer, and is used for improving the overall mechanical performance of the polarizer. In another example, the polarizing film layer is a PVA layer. As another example, the first protective layer is a first TAC layer. In another example, the second protection layer is a second TAC layer or a second COP layer.
The moth eye film is manufactured mainly by using the principle of bionics according to the characteristics of moth eyes. The eyes of the moths flying at night basically do not generate reflected waves to near infrared rays, so that the moths can avoid attracting the attention of natural enemies such as birds and frogs, and the moths have camouflage and concealment performance at night. Through the research on the eyes of the moths, the moths have a layer of three-dimensional hexagonal honeycomb-shaped nano structure, the average height is about 200nm, and the interval between the structures is about 300 nm; therefore, the characteristic size of the moth-eye structure is smaller than the wavelength of most light rays, most incident light rays are absorbed by the honeycomb-shaped nano structure, and the refractive index is continuously changed from top to bottom, so that reflection does not occur or is less. It will be appreciated that the physical colour of an object, typically due to reflection of light of different wavelengths by the object, when all or most of the light is absorbed, causes the article to appear black. Through first protective layer with set up moth's eye membrane between the polarisation rete, moth's eye membrane has the effect that reduces the reflection to the light of inciding from first protective layer to make the polaroid have the effect that reduces the reflection, so, be applied to individual hand-held device and individual hand-held device when being in the screen of breathing, can eliminate or reduce the visual colour difference of the black silk screen printing on LCD display module and apron surface, thereby can improve integrative black technological effect, and then form better effect of breathing out the screen aesthetic.
In order to further improve the reflection reduction effect of the moth-eye film in the polarizer, in an embodiment, referring to fig. 2 and fig. 3, the moth-eye film 200 has a nano moth-eye structure 210 on a side surface close to the polarizing film layer 100. In this way, by providing the nano moth-eye structure 210 on the side of the moth-eye film 200 close to the polarizing film layer 100, the reflection reduction effect of the moth-eye film in the polarizer can be further improved. It should be noted that, when the conventional polarizer is applied to a personal handheld device, the LCD display module has a visual color difference from the black silk screen on the surface of the cover plate, and mainly because when the handheld device is used for screen saving, light with partial wavelength in the light incident from the cover plate is reflected by the LCD liquid crystal in the LCD display module, so that a specific color such as dark brown appears, thereby causing the visual color difference from the black silk screen on the surface of the LCD display module and the cover plate. Through have nanometer moth-eye structure 210 on the side that moth-eye membrane 200 is close to polarisation rete 100, can further absorb from the apron incident light, by the light of the LCD liquid crystal reflection part wavelength in the LCD display module, from the incident light by the LCD liquid crystal reflection part wavelength in the LCD display module of second protective layer one deck promptly to further eliminate or reduce the visual colour difference of the black silk screen printing on LCD display module and apron surface, thereby can improve integrative black technical effect, and then form better information screen aesthetic effect. For another example, the nano moth-eye structure can also be directly understood as a nano moth-eye structure. For another example, referring to fig. 2 and 3, the nano moth-eye structure includes a plurality of protrusions 211, and a maximum distance between the plurality of protrusions is smaller than a visible light wavelength. In another example, the maximum distance between the plurality of projections is 300nm or less (including 300 nm). It should be further noted that the dotted line in fig. 3 is a designation line for convenience of illustrating the overall nano moth-eye structure. For another example, the maximum lateral diameter of the convex portion is equal to or smaller than the wavelength of visible light. For another example, the lateral direction of the convex portion is the lateral direction of the moth-eye film shown in fig. 3. For another example, the maximum lateral diameter of the projection is 300nm or less (including 300 nm). For another example, the height of the convex portion is equal to or less than the wavelength of visible light. For another example, the height of the convex portion is the height of the convex portion along the longitudinal direction, and for another example, the height of the convex portion along the longitudinal direction is the longitudinal direction of the moth-eye film shown in fig. 3. Preferably, the height of the projection is 200nm or less (including 200 nm). Thus, the effect of reducing reflection of the moth-eye film in the polarizer can be further improved. For another example, the convex portion gradually widens in a direction approaching the first protective film layer. For another example, the maximum distance between the plurality of convex portions is the distance between two adjacent convex portions.
It can be understood that after the moth-eye film has the nano moth-eye structure on the side surface close to the polarizing film layer, when the moth-eye film is connected to the polarizing film layer, due to the existence of the nano moth-eye structure, a gap is formed between the nano moth-eye structure and the polarizing film layer, air in the gap may reduce the anti-reflection effect of the moth-eye film in the polarizing film layer to a certain extent, and the anti-reflection effect is the effect of reducing radiation. In order to further improve the antireflection effect of the moth-eye film in the polarizer, in an embodiment, referring to fig. 2, the gap 212 between the nano moth-eye structure 211 and the polarizer layer 100 is further filled with an optical glue (not shown). As described above, by filling the optical adhesive in the gap between the nano moth-eye structure and the polarizing film layer, the optical adhesive has a higher refractive index than air, so that more light can be applied to the nano moth-eye structure, and the antireflection effect of the moth-eye film in the polarizer can be further improved.
In one embodiment, the thickness of the moth-eye film is 10 to 110 micrometers. Thus, the effect of reducing reflection of the moth-eye film in the polarizer can be further improved. For another example, the thickness of the moth-eye film is 50 micrometers to 100 micrometers. As another example, the thickness of the moth-eye film is 75 microns. Thus, the effect of reducing reflection of the moth-eye film in the polarizer can be further improved.
In an embodiment, referring to fig. 4, the polarizer further includes an adhesive layer 500, and the adhesive layer 500 is connected to a side of the second protection layer 400 away from the polarizing film layer 100. It should be noted that the adhesive layer is also called psa (pressure Sensitive adhesive) layer, and is mainly used for adhering the polarizer to the LCD liquid crystal, so as to facilitate the adhesion of the polarizer to the LCD liquid crystal.
In one embodiment, the polarizer further includes a release film layer, and the release film layer is connected to the side surface of the adhesive layer away from the second protective layer. The Release Film layer, also called a Release Film (Release Film) layer, is mainly used for protecting the adhesive layer, and is torn off to expose the adhesive layer thereunder when in use. So, through setting up from the type rete, can protect bonding glue film better. For another example, the release film layer includes a PET sub-layer for providing an integral supporting and mounting function to the release film layer and a silicon release material (Silicone) sub-layer for providing a certain release force to integrally tear the release film layer when the polarizer is used, so as to expose the adhesive layer below. In another example, the average particle size of the silicon release material is 0.2 to 0.9 micrometers, so that the release film layer can be easily torn off. Preferably, the average particle size of the silicon release material is 0.22 to 0.58 micrometers, and more preferably, the average particle size of the silicon release material is 0.28 to 0.36 micrometers, so that the release force is moderate and the adhesive layer can be protected with a reduced amount.
In an embodiment, the polarizer further includes a surface protection film layer, and the surface protection film layer is connected to the side face of the first protection layer away from the polarizing film layer, so that by arranging the surface protection film layer, a certain protection effect can be exerted on the first protection layer, and the polarizer can be further protected. As another example, the Protective Film layer is also called a Protective Film, which consists essentially of PET.
In one embodiment, the polarizer is particularly suitable for an upper polarizer of a display device. In another example, the polarizer is an upper polarizer. For another example, the display device is a display device of a personal handheld device, and certainly, the display device is not limited to the display device of the personal handheld device, and may also be other display devices.
Above-mentioned polaroid, through first protective layer with set up moth's eye membrane between the polarisation rete, moth's eye membrane has the effect that reduces the reflection to the light of inciding from first protective layer to make the polaroid have the effect that reduces the reflection, so, be applied to individual hand-held equipment and individual hand-held equipment when being in the screen of breathing out, can eliminate or reduce the visual colour difference of the black silk screen printing on LCD display module and apron surface, thereby can improve integrative black technological effect, and then form better effect of breathing out the screen aesthetics.

In one embodiment, the forming a nano moth eye structure on one side of the silicon substrate layer specifically includes:
and stamping the side surface of the silicon substrate layer by adopting a mould to form the nano moth-eye structure, wherein a counter body of the nano moth-eye structure is formed on the mould through micro carving. For example, the inverse of the nano-moth-eye structure is the inverted nano-moth-eye structure, and the nano-moth-eye structure is formed on one side of the silicon substrate layer when the silicon substrate layer is imprinted by forming the inverse of the nano-moth-eye structure on a mold.
Therefore, the moth eye film prepared by the method is easier to apply to the production process of the traditional polaroid by a mould stamping technology. The moth-eye film prepared by the die stamping technology has relatively simple process.

C6Hl2O6+2Ag(NH3)2OH→RCOONH4+Ag↓+H2O+3NH3
it should be noted how to use silver mirror reaction to plate silver on one side of the silicon substrate layer to form a silver layer, please refer to the prior art. As another example, the thickness of the silver layer is below the wavelength of visible light.
Therefore, the nanometer moth-eye structure is formed through silver mirror reaction, annealing treatment and etching treatment, the generated nanometer moth-eye structure can be more accurate, and the reflection reduction effect of the moth-eye film in the polaroid can be further improved.
For another example, the etching process sequentially includes the following steps: reactive ion etching, cleaning residual silver particles and plasma processing. It should be noted that, please refer to the prior art for further details of the silver mirror reaction, the annealing process and the etching process, which are not described herein again.

And secondly, the nano moth-eye film and the upper polarizer are adhered together, so that the nano moth-eye film not only has a polarizing function, but also has a reflection reducing function of the moth-eye film, and the effect of breath-holding aesthetics is realized. According to the second scheme, the moth eye structure with the anti-reflection effect is formed by adopting a mold imprinting technology of forming a bionic moth eye through a mold micro-carving on the film material of the silicon-based substrate, and the film with the anti-reflection effect is added into a PVA layer and a TAC layer of the polaroid, so that the polaroid has the effect of reducing reflection, and the effect of achieving the screen-touching aesthetics is further formed.
