Description

Technical Field

[0001] This utility model relates to the field of polarizer design, and in particular to a polarizer structure and display module. Background Technology

[0002] A polarizer, also known as a light polarizer, is an optical material used to control the polarization direction of light. It plays a crucial role in liquid crystal displays (LCDs) and is an indispensable key component of the display panel. The core function of a polarizer is to convert natural light (vibrating in multiple directions) into polarized light in a single direction. Its core material is a polyvinyl alcohol (PVA) film. Through dyeing and stretching processes, iodine molecules are made to form uniform biaxial absorption properties on the PVA film, thereby achieving the polarization effect.

[0003] Currently, during use, polarizers suffer from light leakage or reflection due to uneven scattering or reflection of light, which can cause glare and discomfort to users, thus presenting certain defects. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The protective layer is disposed on both sides of the polarizing layer, and the protective layer is used to protect the polarizing layer and provide mechanical support for the polarizing layer;

[0008] The anti-glare layer consists of two layers, which are located on the outside of the two protective layers. The anti-glare layer reduces glare by reflecting incident light multiple times and extending the light path.

[0017] On the other hand, this utility model also discloses a display module that adopts the above-mentioned polarizer structure.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example:

[0026] like Figure 1 and Figure 2As shown in the figure, this utility model embodiment proposes a polarizer structure, including a polarizing layer 1, a protective layer 2, an anti-glare layer 3, and an adhesive layer 4.

[0027] Specifically, the protective layer 2 is disposed on both sides of the polarizing layer 1. The protective layer 2 is used to protect the polarizing layer 1 and provide mechanical support for the polarizing layer 1.

[0028] The anti-glare layer 3 has two layers, which are located on the outside of the two protective layers 2 respectively. The anti-glare layer 3 reduces glare by reflecting the incident light multiple times and extending the light path.

[0029] The adhesive layer 4 is disposed on one of the anti-glare layers 3, and the adhesive layer 4 is used to adhere and adsorb the surface to be installed.

[0030] In this embodiment, when light passes through the anti-glare layer 3, the anti-glare layer 3 can reflect the incident light multiple times and extend the light path, thereby achieving the light trapping effect, effectively reducing glare and reflection, and thus improving the user's comfort.

[0031] In one specific embodiment, the anti-glare layer 3 is a polylactic acid (PLA) film. One side of the PLA film has a micron-scale uneven structure 6. The uneven structure 6 includes at least one of the following: columnar, conical, spherical, and ridge-shaped.

[0032] The polylactic acid (PLA) film with a micron-scale uneven structure 6 can be fabricated using a template method. First, a template with the micron-scale uneven structure 6 is prepared. Then, PLA material is filled into the template. After the PLA solidifies, the template is removed, yielding a PLA film layer with the corresponding structure. The template can be fabricated using microelectromechanical systems (MEMS) technology or microimprinting technology. For example, using microimprinting technology, the PLA material is first heated to a molten state, and then the template with the uneven structure 6 is imprinted onto the PLA. After cooling, the template separates from the PLA, and the PLA film layer replicates the micron-scale uneven structure 6 of the template.

[0033] In addition, before bonding the polylactic acid film layer to the protective layer 2, the bonding surfaces of both need to be treated to improve the bonding strength. For the polylactic acid film layer, methods such as plasma treatment and chemical oxidation can be used to increase its surface roughness and active groups, making it easier for it to chemically bond or physically adsorb onto the surface of the protective layer 2.

[0034] The light trapping effect refers to the phenomenon that the light path changes due to the structural or material properties when light propagates in an optical element or system. Its core function is to enhance light absorption or reduce reflection loss through specific structural design.

[0035] Furthermore, the polarizing layer 1 is made of polyvinyl alcohol film.

[0036] Specifically, the PVA (polyvinyl alcohol) layer of the polarizer is its core functional layer, responsible for achieving polarization by selectively absorbing light waves in specific directions.

[0037] The polarizer structure consists of multiple layers. The core layer is a polyvinyl alcohol layer, which is stretched and oriented to form a grating structure. Transparent protective layers 2 cover the top and bottom, and adhesive is applied to both sides. The overall thickness is approximately 0.1 mm. This structure allows light vibrations in a specific direction to pass through, while light perpendicular to the polarizer is absorbed, achieving a light polarization effect.

[0038] Furthermore, the protective layer 2 is made of cellulose triacetate film.

[0039] Specifically, cellulose triacetate film (TAC film) primarily functions as a support and protector in polarizers. The TAC film is a crucial component of the polarizer; by supporting and protecting the core material, the PVA film, it ensures the stability and durability of the polarizer. Its specific functions are as follows:

[0040] 1. Support function: The TAC film can support and protect the extended PVA film, preventing it from shrinking back, thereby ensuring the stability of the polarizer.

[0041] 2. Protective function: TAC film has high light transmittance and low scattering rate, which can effectively reduce the damage of external factors such as water vapor, ultraviolet rays and external forces to PVA film and extend the service life of polarizer.

[0042] Furthermore, a release film layer 5 is provided on the outer side of the adhesive layer 4, and the release film layer 5 is made of PET film.

[0043] Specifically, the adhesion layer 4 uses pressure-sensitive adhesive, which is an acrylic adhesive with a thickness of about 10-25μm, to attach the polarizer to the surface of the liquid crystal panel.

[0044] In addition, the release film is made of PET film and is adhered to the surface of adhesive layer 4 to isolate the pressure-sensitive adhesive. The release film needs to be removed when the polarizer is subsequently attached to the LCD panel.

[0045] Example 2:

[0046] On the other hand, this utility model also discloses a display module that adopts the above-mentioned polarizer structure.

[0047] Compared with the prior art, the present invention has at least the following beneficial effects:

[0048] This invention achieves a light trapping effect by setting an anti-glare layer on the outside of the protective layer and using the anti-glare layer to reflect the incident light multiple times and extend the light path. This greatly reduces glare and reflection, thereby improving the optical performance of the polarizer. It features a simple structure and convenient production.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
