Features of various aspects of the present application and exemplary embodiments will be described in detail below. Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

The polarizer is a component frequently used in the existing display panel, the polarizer is used in the liquid crystal display device to display images, and the polarizer is used in the OLED display device to convert linearly polarized light into circularly polarized light, so that the adverse effect of ambient light on the display effect of the screen body is eliminated. Meanwhile, the structure that plays a main polarizing role in the existing polarizer is usually a three-layer laminated structure composed of a TAC (Triacetyl Cellulose) layer, a PVA (polyvinyl alcohol) layer, and a TAC layer, which are sequentially arranged, and at this time, the display luminance of the display device using the polarizer is significantly reduced due to the influence of the light transmittance and the filtering effect of the polarizer itself.

The inventors found that by providing a microlens structure in a polarizer, the transmittance of the polarizer can be effectively improved by the effect of focusing imaging by the microlenses. The conventional polarizer or display device usually has an additional layer structure disposed in the display device, which can play a role of improving transmittance to some extent, but has corresponding drawbacks, mainly manifested as a complicated structure, an increased thickness of the polarizer, and being not conducive to making the display device light and thin.

In order to solve the foregoing technical problems, embodiments of the present disclosure provide a polarizer, which can effectively improve the transmittance of the polarizer, and has the advantages of being simple and convenient to process, and not increasing the thickness of the polarizer.

Further, in order to better understand the present application, the polarizer and the display device provided in the embodiments of the present application are described in detail below with reference to fig. 1 to 8.

Referring to fig. 1 and fig. 2 together, fig. 1 is a schematic structural diagram of a polarizer provided in an embodiment of the present application, and fig. 2 is another schematic structural diagram of the polarizer provided in the embodiment of the present application. The embodiment of the application provides a polarizer 10, have income plain noodles 101 and the play plain noodles 102 of relative setting, polarizer 10 includes polarizing layer 12 and sets up in the first membrane layer group 11 and the second membrane layer group 13 of polarizing layer 12 relative both sides, and at least one of polarizing layer 12, first membrane layer group 11 and the second membrane layer group 13 is provided with microlens structure 14, and microlens structure 14 is including being a plurality of microlens unit 141 of array distribution, and microlens unit 141 is the protrusion towards income plain noodles 101.

The number of the microlens structures 14 disposed in the polarizer 10 is not limited in the embodiment of the present application, and may be specifically set according to a desired transmittance standard. As an example, the polarizer 10 includes a plurality of microlens structures 14, and the thickness of the film between two adjacent microlens structures 14 is equal. It will be appreciated that, as some alternative examples, the film thickness may be different between two adjacent layers of microlens structures 14. Similarly, as some optional examples, the diameter of the microlens unit 141 in each layer of the microlens structure 14 may be the same, and as other optional examples, the diameter of the microlens unit 141 disposed in the same layer may be different.

As an alternative example, the material of the microlens structure 14 in the polarizer 10 may be the same as the layer structure in which it is located, for example: the microlens structure 14 provided in the first module group 11 may be made of the same material as the layer structure of the first module group 11 adjacent to the microlens structure 14, and the microlens structure 14 provided in the polarizing layer 12 may be made of the same material as the polarizing layer 12.

As some optional examples, the microlens structures 14 in the polarizer 10 may be provided as a full layer; in other alternative examples, the microlens structure 14 may be disposed along different layers and separately cover a portion of the area of the layer structure.

The embodiment of the application provides a polarizer 10, which includes a first film layer group 11, a polarizing layer 12 and a third film layer group 13, which are sequentially stacked, at least one of the three film layer structures is provided with a microlens structure 14, a plurality of microlens units 141 included in the microlens structure 14 protrude toward the light incident surface 101 of the polarizer 10, that is, the microlens structure 14 includes a plurality of microlenses having convex surfaces and capable of converging light rays, and the microlenses extend along a plane perpendicular to the thickness direction, the convex surfaces of the microlens units 141 face the same direction, and the focal lengths of the microlens units 141 disposed on the same layer are the same, so that the microlens structures 14 extending along the same layer can converge and converge the light rays incident to the structure to form a focal plane, and reduce the scattering of the light rays in the internal propagation process of the polarizer 10, thereby transmitting more light rays along a preset direction, the transmittance of the polarizer 10 is effectively improved.

Referring to fig. 3, fig. 3 is another structural schematic diagram of a polarizer provided in an embodiment of the present disclosure. In some alternative embodiments, the first film layer group 11 includes a first protection layer 111 disposed adjacent to the polarizing layer 12, the second film layer group 13 includes a second protection layer 131 disposed adjacent to the polarizing layer 12, the microlens structure 14 is disposed at an interface of the first protection layer 111 and the polarizing layer 12 and/or the microlens structure 14 is disposed on a side surface of the second protection layer 131 away from the polarizing layer 12.

As some optional examples, the polarizing layer 12 may be a PVA layer dyed by iodine, and the first protective layer 111 and the second protective layer 131 may be TAC layers, so as to form a core portion of a relatively complete iodine-based polarizer, and meanwhile, the polarizer 10 may also use another dye-based polarizer, or use a resin-based material instead of the TAC layer, and the like, which is not limited in this application.

The polarizer 10 in the embodiment of the present application may include a first protective layer 111, a polarizing layer 12, and a second protective layer 131 that are sequentially disposed adjacent to each other, and the three-layer structure stacked in this way has two interfaces, and the microlens structure 14 may be disposed at these interfaces, and the microlens structure 14 may be disposed at one of the interfaces, or both of the interfaces are disposed with the microlens structure 14. The micro-lens structure 14 is arranged on the surface of one side of the film layer structure, so that the micro-lens structure 14 can be processed more conveniently, can be formed by adopting various methods such as bonding, etching, integrated forming and the like, can be prepared simultaneously when the film layer structure is prepared, and is convenient for improving the production efficiency.

When the first mode group 11, the polarizer 12, and the second mode group 13 are bonded, a bonding agent commonly used in the conventional polarizer may be used, and this is not specifically limited in the present application. Further, taking the structure in which the microlens structure 14 is disposed on the surface of the first protection layer 111 close to the polarizing layer 12 as an example, when the convex surface of the microlens structure 14 is bonded to the polarizing layer 12, an adhesive may be first coated on the surface of the microlens structure 14, and the adhesive is leveled, so that the gaps and the depressions between the adjacent microlens units 141 are fully filled before curing, thereby preventing the surface of the microlens structure 14 with the unevenness from affecting the polarizing layer 12, or preventing the surface of the microlens structure 14 from being damaged due to bonding and pressing.

Referring to fig. 4 to 6 together, fig. 4 to 6 are various structural schematic diagrams of the polarizer provided in the embodiment of the present application. In some alternative embodiments, the microlens structure 14 is disposed on the first protective layer 111 and the second protective layer 131; the light entering the polarizer 12 from the light incident surface 101 is focused to the first focal plane 15 on the light emitting surface 102 side through a part of the microlens structures 14 of the second protective layer 131, and the other part is focused to the first focal plane 15 through the microlens structures 14 of the first protective layer 111; and/or, all the light entering polarizer 12 from light incident surface 101 passes through microlens structure 14 of second protective layer 131 and is further focused to second focal plane 16 on light emitting surface 102 side again through microlens structure 14 of first protective layer 111, where first focal plane 15 and second focal plane 16 are parallel.

Referring to fig. 4, when the polarizer 10 provided in the embodiment of the present application has two or more microlens structures 14, each microlens structure 14 may be disposed in a whole layer, and all incident light is focused to the first focal plane 15 through the first microlens structure 14, and then focused to the second focal plane 16 through the second microlens structure 14. Alternatively, the microlens structures 14 of one or some of the layers may be arranged in a whole layer, while the rest of the microlens structures 14 are alternately and complementarily arranged according to the method, and finally, the microlens structures 14 covering the polarizing layer 12 may also be formed and the light converging effect is achieved.

Referring again to fig. 5, it can be understood that the microlens units 141 disposed in the plurality of different microlens structures 14 may have different radial dimensions, i.e., the patterns of the plurality of microlens structures 14 may be arranged differently. When light passes through one layer of microlens structure 14, a small part of light irradiated on each microlens unit 141 is gathered to the focal point of the microlens unit 141, and finally gathered on the same focal plane, and the microlens structures 14 with different sizes are arranged to scatter and rearrange the partition and the propagation direction of the light focused by the first layer of microlens structure 14, that is, the light which is once converged is converged again according to the partition of the areas with different sizes and different positions, so that the light-emitting uniformity of the polarizer 10 can be improved on the basis of further improving the transmittance.

In correspondence with the foregoing arrangement method, referring to fig. 6 again, fig. 6 exemplarily illustrates an embodiment in which light rays incident on the light incident surface 101 of the polarizer 10 are respectively condensed to the same focal plane by the microlens structures 14 of different layers arranged in the polarizer 10. At this time, at least two layers of microlens structures 14 are disposed in the polarizer 10, and the orthographic projection of the microlens structures 14 on the polarizing layer 12 can completely cover the polarizing layer 12, that is, it can be understood that the microlens structures 14 continuously extending on the same layer are split into a plurality of blocks, and a part of the blocks is moved to a position of a layer different from the original microlens structures 14 along the thickness direction of the polarizer 10, so that the microlens structures 14 are distributed at positions of a plurality of different layers.

Based on the foregoing arrangement, taking the example that two layers of microlens structures 14 are simultaneously disposed in the polarizer 10, the two layers of microlens structures 14 may be alternately disposed in a plurality of regions, that is, the set of orthographic projections of the two layers of microlens structures 14 on the polarizing layer 12 completely covers the polarizer 12, and the orthographic projections of the two layers of microlens structures 14 on the polarizing layer 12 are not overlapped/only slightly overlapped. Meanwhile, the size and the focal length of the microlens units 141 in the two microlens structures 14 can be adjusted, so that the two microlens structures 14 focus the incident light on the same focal plane, i.e., focus and image on the same plane alternately in a regional manner. By focusing and projecting the incident light to the same focal plane through the microlens structures 14 arranged in different layers, the definition and uniformity of the light passing through the polarizer 10 can be further improved.

Referring to fig. 7, fig. 7 is a schematic structural diagram of a polarizer according to an embodiment of the present disclosure. In some optional embodiments, the second film layer group 13 further includes a pressure sensitive adhesive layer 132 and a release film layer 133, and the pressure sensitive adhesive layer 132 is disposed between the polarizing layer 12 and the release film layer 133.

In the polarizer 10, the second module group 13 is closer to the light incident surface 101, that is, in the use state of the polarizer 10, the second module group 13 is closer to the display panel that needs to be connected to the polarizer 10, so the second module group 13 may further include a pressure sensitive adhesive layer 132 and a release film layer 133 that are sequentially disposed, in addition to the second protective layer 131 that is closest to the polarizing layer 12, and a protective film may be further disposed on the outer surface of the release film layer 133 that is away from the pressure sensitive adhesive layer 132. Wherein, the pressure-sensitive adhesive layer 132 should be made of a material with good adhesiveness, good transparency and less residual adhesive, and is used for adhering and fixing the polarizer 10; the release film layer 133 should be made of a material with high strength, good transparency and good deformation resistance, so as to protect the pressure-sensitive adhesive layer 132 from being damaged before the attachment and the removal.

Further, according to a scenario that the polarizer 10 needs to be applied and a function that needs to be implemented, the second mold layer group 13 may further include film layer structures such as a reflective film and a phase difference film, and the second mold layer group 13 includes the second protective layer 131, the pressure sensitive adhesive layer 132 and the release film layer 133 in this application as an example for description, but it should be understood that the application is not limited thereto.

Referring to fig. 8 and 9 together, fig. 8 is a schematic top view of the polarizer 10 provided in the embodiment of the present application, and fig. 9 is a schematic structural diagram of the polarizer 10 provided in the embodiment of the present application. In some alternative embodiments, the microlens structures 14 are disposed on the polarizing layer 12; the polarizing layer 12 is a whole-layer plane structure, and a plurality of microlens units 14 are distributed in a connected manner in the whole plane of the polarizing layer 12; alternatively, the polarizing layer 12 is a patterned structure including a plurality of grooves 121, and each microlens unit 141 is disposed corresponding to each groove 121.

The polarizer 10 provided in the embodiment of the present application includes the polarizing layer 12, and when the microlens structure 14 is disposed on one side surface of the polarizing layer 12, the microlens structure 14 may be disposed in a whole layer, and the microlens units 141 are distributed in a contiguous manner, that is, the edges of the plurality of microlens units 141 are adjacently disposed in a mutually contacting manner and closely arranged, so that focused imaging is formed to the maximum extent, and the transmittance of the polarizer 10 is increased.

Or, as some alternative examples, the polarizing layer 12 may have a plurality of grooves 121, and the microlens units 141 are disposed in the grooves 121, so that the thickness of the polarizer 10 can be further reduced by disposing the microlens units 141 in the grooves 121. One or more microlens units 141 may be disposed in each groove 121 corresponding to the size of the groove 121, and meanwhile, the sizes of the plurality of grooves 121 may be different, and accordingly, the number of the microlens units 141 therein may also be different.

It can be understood that there is a certain gap between the grooves 121, but the size of the gap needs to be limited, and an excessively large gap may cause uneven brightness of light passing through the polarizer 10, thereby forming regions with different brightness corresponding to the grooves 121, and further affecting the display effect. The size of the gap is in direct proportion to the diameter of each microlens unit 141, that is, the larger the size of the microlens unit 141 is, the larger the gap between the grooves 121 can be correspondingly, and the specific value of the gap needs to be designed according to the size of the microlens unit 141 and the number of the microlens units 141 in each groove 121.

In some alternative embodiments, the plurality of grooves 121 have the same size and are arranged in an equally spaced array.

Based on the design of the grooves 121, in order to increase the light transmission uniformity of the polarizer 10, the grooves 121 may have the same size and are arranged in an equally spaced array, and at this time, the microlens units 141 may also have the same size, so that the focused image has good brightness uniformity through the uniformly arranged microlens units 141, and the brightness uniformity of the light emitted by the polarizer 10 is finally improved.

In some alternative embodiments, the microlens structure 14 is an integrally formed structure with at least one of the polarizing layer 12, the first film layer set 11, and the second film layer set 13 attached thereto; alternatively, the microlens structure 14 is an independent film layer structure, and at least one of the polarizing layer 12, the first film layer group 11, and the second film layer group 13 connected to itself is bonded.

Corresponding to the foregoing method for selecting the material of the microlens structure 14, the microlens structure 14 may be integrally formed with the film structure on which it is disposed, or the microlens structure 14 may be a layer made of a corresponding material and is adhered and fixed to the film structure on which it is disposed, and at this time, the adhesion between the microlens structure 14 and the film structure may be made by using an adhesive commonly used in the conventional polarizer, such as a pressure sensitive adhesive, to ensure reliability and reduce cost.

It can be understood that, the microlens structure 14 is preferably manufactured by integrally forming a film layer on the microlens structure, the manufacturing method is simple in process and low in cost, and the obtained part has high structural strength, so that the risk of adverse conditions possibly caused by adhesion processes such as peeling, dislocation and air bubbles can be avoided, and the production yield and reliability of the microlens structure 14 can be improved. Meanwhile, the microlens structure 14 manufactured by integral molding does not need to be provided with an additional adhesive layer, so that the thickness of the polarizer 10 can be further reduced, and the thinning of the display device is facilitated.

In some alternative embodiments, the microlens unit 141 is a convex lens or a screw lens.

The polarizer 10 provided in the embodiments of the present application is provided with a microlens structure 14. The microlens structure 14 is formed of a plurality of microlens units 141, and the microlens units 141 may be formed of a plano-convex lens, a biconvex lens, a fresnel lens, or the like, and the fresnel lens has a better effect than a conventional convex lens.

The Fresnel lens is also called as a screw lens and is obtained by cutting a continuous curved surface of a common convex lens into a discontinuous curved surface with invariable curvature and arranging a plurality of independent sections on the same frame. Use fresnel lens can further improve ordinary convex lens edge luminance decline's problem, and fresnel lens can take place the curved surface of refraction with light when saving the partial route that light rectilinear propagation passed through in convex lens and remain, consequently can further reduce light through lens and the light quantity of loss to use less material to obtain the light concentration effect that luminance is higher.

Therefore, in order to further increase the transmittance of the polarizer 10 and reduce the thickness of the polarizer 10, the microlens unit 141 in the embodiment of the present application may preferably adopt a fresnel lens. At this time, the fresnel lens may be formed by printing a material with a higher refractive index, so that the microlens structure 14 has higher precision and better light transmission effect.

In some alternative embodiments, the plurality of microlens units 141 have the same size.

The microlens structure 14 provided in the embodiment of the present application is provided with a plurality of microlens units 141, and when only one layer of microlens structure 14 is provided in the polarizer 10, the sizes of the plurality of microlens units 141 may be the same; when multiple layers of microlens structures 14 are disposed in the polarizer 10, the microlens units 141 in the same layer of microlens structures 14 may have the same size, and the sizes of the microlens units 141 in two adjacent layers of microlens structures 14 may be different, or some layers may be the same, different from other layers, or all the layers may be the same.

Providing all of the microlens units 141 as a structure having the same size can facilitate designing and processing of the microlens structure 14, and also facilitate controlling the arrangement of the microlens units 141.

In some alternative embodiments, the orthographic projection of the plurality of lenticular units 141 on the polarizing layer 12 covers the entire polarizing layer 12.

The microlens unit 141 in the embodiment of the present application can be set for the whole layer, and completely covers the polarizing layer 12, so that the light passing through the polarizer 10 can be focused and imaged through the microlens unit 141, thereby the transmittance of the whole polarizer 10 can be completely improved, and the problem of uneven display at the edge is avoided.

It is understood that the orthographic projection of the microlens units 141 on the polarizing layer 12 to cover the polarizing layer 12 can be achieved by various designs, for example, there can be multiple layers of microlens structures 14 arranged in the polarizer 10, the orthographic projection of each layer of microlens structure 14 covers part of the polarizing layer 12, and the orthographic projection of the multiple layers of microlens structures 14 can be combined to completely cover the polarizing layer 12. Alternatively, only one layer of the microlens structure 14 may be provided and the entire layer may be provided, i.e., the orthographic projection of a single layer of the microlens structure 14 completely covers the polarizing layer 12. Alternatively, when multiple layers of microlens structures 14 are provided, one of the layers may be provided in a single layer, and the rest is not limited.

In summary, the arrangement of the microlens unit 141 is enough to enable all the light rays incident from the light incident surface 101 to pass through the microlens unit 141, and the specific implementation manner of the microlens unit is not particularly limited in this application.

In a second aspect, please refer to fig. 10 and fig. 11 together, wherein fig. 10 is a schematic structural diagram of a display device 100 according to an embodiment of the present application, and fig. 11 is a cross-sectional view taken along line a-a' of fig. 10. The embodiment of the present application provides a display device 100, which includes the foregoing polarizer 10 and display panel 20, wherein the light incident surface 101 of the polarizer 10 is disposed close to the display surface of the display panel 20.

The display device 100 is provided with a polarizer 10 and a display panel 20, and the display panel 20 may be an OLED display panel or a liquid crystal display panel. When the display panel 20 is a liquid crystal display panel, the polarizer 10 may be used as an upper polarizer of the liquid crystal display device 100, and when the display panel 20 is an OLED display panel, the polarizer 10 may be used to prevent ambient light reflected by the display panel 20 from interfering with display of the display device 100. Meanwhile, the display device 100 may be any product or component having a display function, such as a mobile phone, a tablet computer, a digital photo frame, and electronic paper, which is not limited in this application.

It is understood that the polarizer 10 and the display panel 20 may be fixed by adhesion through the Adhesive layer 30, wherein the Adhesive layer 30 may use an Adhesive with high light transmittance, such as OCA (Optically Clear Adhesive) or OCR (Optically Clear Resin), to avoid affecting the overall light transmittance.

In the display device 100, the display surface of the display panel 20 is adjacent to the light incident surface 101 of the polarizer 10, and in the using process, the display panel 20 displays a corresponding picture, and the light emitted from the display surface of the panel enters the polarizer 10 through the light incident surface 101 and is focused through the microlens structure 14 therein, so as to improve the transmittance of the polarizer 10.
