Description

Technical Field

[0001] This application relates to the field of optical films and protective structures for displays, and in particular to an AB film and a display protective structure used for converting light in a display. Background Technology

[0002] As vehicles become increasingly intelligent, in-vehicle displays have become multifunctional interactive interfaces. These displays are used not only for navigation and entertainment systems but also for safety assistance systems. To enhance user experience and driving safety, various display protection technologies are constantly emerging. For example, tempered glass protective screens, anti-glare coatings, and anti-reflective films all improve screen durability and visibility to some extent. However, these issues do not completely solve the visual impairment problem encountered by drivers wearing sunglasses in strong sunlight.

[0003] Existing solutions typically involve using polarization filters, multilayer composite films, or specially treated surface coatings. Polarization filters reduce the impact of reflected light by altering the polarization state of incident light; multilayer composite films enhance overall screen performance by stacking layers with different functions, such as scratch-resistant and fingerprint-resistant layers; and specially treated surface coatings reduce reflectivity and improve the viewing experience. While these methods can alleviate visual interference under strong light to some extent, they cannot completely solve the problem of obstructed vision caused by polarizers.

[0004] Current solutions on the market have significant shortcomings, especially in dealing with strong light environments and when wearing sunglasses, where screen visibility remains poor. Specifically: while polarization filters can reduce reflected light, they can cause the screen to dim or even become unreadable at certain angles; multi-layer composite films increase costs and may affect screen transmittance; and specially treated surface coatings have limited effectiveness and cannot effectively address the viewing angle limitations caused by polarization. Therefore, a new technological solution is needed to overcome these deficiencies and ensure that drivers can clearly view screen information under any lighting conditions. Utility Model Content

[0005] The purpose of this application is to provide an AB film for use with displays to convert light.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: an AB adhesive film for converting light in a display, comprising: a first release film, a second release film, and an AB adhesive layer, wherein the AB adhesive layer comprises an optical-grade acrylic resin layer, a polycarbonate film layer, and an optical-grade silicone pressure-sensitive adhesive layer; the optical-grade acrylic resin layer is used to bond the polycarbonate film layer to the first release film, and the optical-grade silicone pressure-sensitive adhesive layer is used to bond the polycarbonate film layer to the second release film.

[0007] By employing the above technical solution, effective light conversion can be achieved. Optical-grade acrylic resin layers and optical-grade silicone pressure-sensitive adhesive layers bond the polycarbonate film layers, ensuring the stability and structural integrity of the film. As a key component, the polycarbonate film layer, through synergy with other materials, exhibits unique optical properties, positively influencing light propagation, refraction, and reflection. Simultaneously, the combination of different material choices and layered structures allows for selective light transmission or absorption, optimizing the display effect, enhancing visibility and color performance, and providing users with a better visual experience. The excellent bonding between layers improves the overall durability and reliability of the film, enabling it to better perform its functions during long-term use and maintain stable optical performance under different environmental conditions, extending its lifespan and meeting the light conversion and protection needs of displays in various usage scenarios.

[0008] Optionally, the thickness of the polycarbonate film layer is 20μm-500μm.

[0009] By adopting the above technical solution, this thickness range provides sufficient physical support for the film, ensuring good structural stability when bonded to the first and second release films via optical-grade acrylic resin and optical-grade silicone pressure-sensitive adhesive layers. This prevents tearing and deformation caused by excessive thinness, while avoiding the impact of excessive thickness on the overall flexibility and adhesion of the film. From an optical performance perspective, this thickness range allows for precise adjustment of the light propagation path and effect within the film, resulting in better controllability and accuracy in light conversion. For example, a suitable thickness helps to precisely control the polarization, scattering, and refraction properties of light, thereby achieving superior light conversion effects and providing finer adjustments for display performance, meeting the diverse needs of different users regarding display quality and viewing angles. Furthermore, the polycarbonate film layer within this thickness range ensures the optical uniformity of the entire film, reducing uneven light conversion or localized optical performance differences caused by uneven thickness, further enhancing the visual effect and display quality of the display when using this AB film.

[0010] Optionally, ultraviolet and blue light blocking agents are added to the optical-grade acrylic resin layer.

[0011] By employing the above technical solution, the optical-grade acrylic resin layer with added ultraviolet and blue light blockers can effectively block or reduce the transmission of these harmful rays, protecting the user's eyes and reducing the potential health risks associated with long-term monitor use. From a display performance perspective, reducing ultraviolet and blue light interference makes the monitor's color reproduction more accurate and natural, avoiding the adverse effects of these rays on color reproduction and improving the quality and realism of the displayed image. The blocking function of harmful rays adds extra protection to the display device without affecting its normal operation, improving its adaptability and reliability under different lighting conditions, extending the monitor's lifespan, and creating a more comfortable and healthy viewing environment for users, meeting higher usage demands and health standards for monitors.

[0012] Optionally, the optical-grade silicone pressure-sensitive adhesive layer contains ultraviolet and blue light blocking agents.

[0013] By adopting the above technical solution, since the silicone pressure-sensitive adhesive plays an important role in bonding and sealing in the AB film structure, adding these barrier agents can further enhance the entire film system's ability to block ultraviolet and blue light. It can effectively intercept potentially transmitted ultraviolet and blue light at the adhesive layer level, working synergistically with other possible barrier layers or agents to provide a more comprehensive harmful light protection system for the entire film system, preventing these rays from passing through the film and causing potential harm to the user's eyes. The silicone pressure-sensitive adhesive with added barrier agents, while ensuring good adhesion, also gives the film better optical properties. By reducing interference from ultraviolet and blue light, the quality of the displayed image can be improved, reducing problems such as color cast and distortion caused by harmful light, making the image displayed on the monitor clearer and the colors more realistic. It also improves the stability and reliability of the monitor in different usage environments, providing users with a more comfortable and high-quality user experience, thereby improving the overall performance and quality of the monitor and demonstrating better comprehensive optical and protective performance advantages.

[0014] Optionally, the thickness of the optical grade acrylic resin layer is 15μm-1000μm.

[0015] By adopting the above technical solution, from the perspective of structural stability, this thickness range can provide suitable structural support for the entire AB film, ensuring that it can maintain good shape and structural integrity under different usage conditions. This avoids the structural fragility caused by excessive thinness and the heaviness and potential impact on the function of other layers caused by excessive thickness. In terms of optical performance, a suitable thickness helps optimize the propagation and conversion of light within the film. Different thicknesses affect the transmission and interaction of light within the acrylic resin layer. This thickness range allows for better modulation of light; for example, the transmittance, reflectivity, or scattering properties can be adjusted according to actual needs to achieve better display effects, such as improving the contrast and brightness uniformity of the displayed image. Simultaneously, this thickness range allows the optical-grade acrylic resin layer to better utilize its own characteristics when combined with other layers, such as polycarbonate film layers and release films, enhancing the optical synergy between layers. This results in higher quality and more stable light conversion and display performance for the display, meeting diverse usage scenarios and users' different needs for display effects.

[0016] The second objective of this application is to provide a display protection structure, comprising a protective layer and an AB adhesive layer bonded to the protective layer. The AB adhesive layer includes an optical-grade acrylic resin layer, a polycarbonate film layer, and an optical-grade silicone pressure-sensitive adhesive layer. The optical-grade acrylic resin layer is used to bond the polycarbonate film layer to the protective layer, and the optical-grade silicone pressure-sensitive adhesive layer is used to bond the polycarbonate film layer to the display.

[0017] By adopting the above technical solution, the structure, composed of a protective layer and an AB adhesive layer, wherein the AB adhesive layer comprises an optical-grade acrylic resin layer, a polycarbonate film layer, and an optical-grade silicone pressure-sensitive adhesive layer, provides excellent overall performance. The optical-grade acrylic resin layer and the optical-grade silicone pressure-sensitive adhesive layer respectively serve to bond the polycarbonate film layer to the protective layer and the polycarbonate film layer to the display, ensuring a tight bond between the components. This provides reliable physical protection for the display, preventing direct damage from external factors such as scratches, dust, and moisture. The polycarbonate film layer, as an important component of this protective structure, due to its inherent properties, not only provides physical protection but also modulates light, thus affecting the display effect and improving visibility and display quality. The tight multi-layered structure effectively combines the performance advantages of each layer, not only providing physical protection but also potentially improving the display's optical performance, providing a stable working environment, extending its lifespan, and providing users with a better experience. This meets the dual needs of protection and performance enhancement for displays in complex operating environments.

[0018] Optionally, the protective layer is made of optical-grade transparent tempered glass, and the thickness of the protective layer is 0.1mm-5.0mm.

[0019] By adopting the above technical solution and using optical-grade transparent tempered glass as a protective layer, its transparency ensures that the display image remains unobstructed, allowing light to pass through efficiently without affecting the user's viewing experience. Tempered glass possesses high strength and hardness, providing excellent physical protection for the monitor, effectively resisting external mechanical impacts, scratches, and other physical damage, significantly reducing the risk of damage during daily use, transportation, or accidental collisions. The 0.1mm-5.0mm thickness range is carefully considered. A protective layer that is too thin may not provide sufficient protection, while a layer that is too thick may increase the weight and thickness of the entire protective structure, affecting the monitor's portability and aesthetics. Within this thickness range, the tempered glass protective layer fully leverages its physical protection advantages while also considering the monitor's overall appearance and user experience to a certain extent. This ensures that the monitor receives good protection without becoming bulky due to an excessively thick protective layer, or affecting its heat dissipation or other aspects. Therefore, it provides a safe, aesthetically pleasing, and practical protective barrier for the monitor, improving its overall reliability and durability.

[0020] Optionally, a blue light blocking layer is also included, disposed between the optical-grade silicone pressure-sensitive adhesive layer and the polycarbonate film layer.

[0021] By adopting the above technical solution, the addition of the blue light blocking layer can further enhance the blocking effect on blue light emitted from the monitor, effectively reducing the potential harm of blue light to users' eyes, especially during prolonged monitor use, thus better protecting users' eye health. The blue light blocking layer, in conjunction with other existing components with blue light blocking functions (such as blue light blockers added to optical-grade acrylic resin layers or optical-grade silicone pressure-sensitive adhesive layers), forms a more comprehensive blue light protection system, providing more comprehensive and efficient filtering and blocking of blue light, avoiding problems such as eye fatigue and decreased vision caused by excessive blue light. The positioning of the blue light blocking layer allows it to act precisely on the light propagation path, specifically blocking blue light without affecting the function of other layers, optimizing the monitor's optical performance, improving the quality of the displayed image and color reproduction, providing users with a more comfortable and healthier viewing experience, and further enhancing the performance and advantages of the monitor's protective structure in terms of optical protection, thus strengthening its competitiveness in the market.

[0022] In summary, this application has at least the following beneficial effect:

[0023] 1. AB film contains a variety of optical materials, such as a polycarbonate film layer, an optical-grade acrylic resin layer, and an optical-grade silicone pressure-sensitive adhesive layer. The polycarbonate film layer can be adjusted within a certain thickness range, enabling the conversion of light, such as converting linearly polarized light emitted by the display into circularly polarized light, thereby optimizing the display effect and enhancing the visibility and color performance. At the same time, the optical synergy between different layers can precisely control the propagation, refraction, reflection, polarization, and scattering characteristics of light, improving the quality of the displayed image.

[0024] 2. It adopts a multi-layered AB film and monitor protection structure, providing physical protection for the monitor and effectively preventing damage from external factors such as scratches, dust, and moisture. It adds ultraviolet and blue light blocking agents to different layers, and even sets up a special anti-blue light layer to form a complete protection system. This can reduce the damage of harmful light (such as ultraviolet and blue light) to the user's eyes, extend the life of the monitor, and protect the user's eye health. Attached Figure Description

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] In this embodiment, refer to Figure 1 An AB adhesive film for converting light in a display includes a first release film 1, a second release film 2, and an AB adhesive layer 3. The AB adhesive layer 3 is composed of an optical-grade acrylic resin layer 31, a polycarbonate film layer 32, and an optical-grade silicone pressure-sensitive adhesive layer 33. The optical-grade acrylic resin layer 31 bonds the polycarbonate film layer 32 to the first release film 1, and the optical-grade silicone pressure-sensitive adhesive layer 33 bonds the polycarbonate film layer 32 to the second release film 2. This structural design effectively solves the problem of obstructed vision caused by polarizers, allowing drivers to clearly see screen information even when wearing sunglasses.

[0032] Specifically, the first release film 1 can be made of PET (polyethylene terephthalate) or PE (polyethylene). Both materials have good release properties and heat resistance, and can maintain stable peel force at high temperatures. The main function of the first release film 1 is to protect the AB adhesive layer 3 during the production process, preventing contamination and damage.

[0033] The second release film 2 can also be made of PET or PE material. The function of the second release film 2 is similar to that of the first release film 1, mainly used to protect the other side of the AB adhesive layer 3, ensuring that the AB adhesive layer 3 is not affected by the external environment before use.

[0034] The AB adhesive layer 3 is the core of the entire structure, consisting of three main components: an optical-grade acrylic resin layer 31, a polycarbonate film layer 32, and an optical-grade silicone pressure-sensitive adhesive layer 33. These components each perform different functions and work together to achieve the light conversion effect.

[0035] The optical-grade acrylic resin layer 31 is mainly used to bond the polycarbonate film layer 32 to the first release film 1. Acrylic resin has high transparency and excellent adhesion, effectively fixing the polycarbonate film layer 32 onto the first release film 1. Furthermore, acrylic resin also exhibits excellent weather resistance and chemical stability, making it suitable for long-term outdoor use.

[0036] The polycarbonate film layer 32 is a key component of the AB adhesive layer 3, with a thickness ranging from 20μm to 500μm. The polycarbonate film layer 32 possesses high birefringence and phase retardation, enabling it to convert the linearly polarized light emitted by the display 5 into more eye-friendly circularly polarized light. This conversion not only improves viewing comfort but also effectively solves the problem of blackening of the display 5 when viewed with polarized sunglasses, achieving a 360-degree viewing angle. The polycarbonate film layer 32 is stretched and oriented using a biaxial stretching device. This device can apply uniform tension to the film in either the transverse or longitudinal direction, ensuring uniform stretching in a specific direction to achieve the desired orientation effect.

[0037] Before stretching, the molecular arrangement of the polycarbonate film layer 32 is relatively disordered. After stretching, the microstructure of the polycarbonate film layer 32 becomes ordered, changing the material's refraction and propagation properties of light and creating favorable optical conditions for polarization conversion. This ordered arrangement causes the molecular chains to orient along the stretching direction, resulting in an increase in birefringence and phase retardation. Higher birefringence means a greater difference in the propagation speed of light in different directions, which is crucial for converting linearly polarized light into circularly polarized light. The increase in phase retardation helps to precisely control the change in the polarization state of light, enabling better conversion from linearly polarized to circularly polarized light when passing through the film.

[0038] Unstretched and unaligned polycarbonate film layer 32 cannot effectively convert linearly polarized light emitted by display 5 into circularly polarized light. When viewed with polarized sunglasses, because polarized sunglasses only allow polarized light in a specific direction to pass through, a large amount of light is blocked at certain angles, making display 5 appear dark. After stretching and alignment, polycarbonate film layer 32 can convert linearly polarized light into circularly polarized light. The characteristic of circularly polarized light is that its electric field vector rotates during propagation and no longer has a specific polarization direction. Therefore, when it passes through polarized sunglasses, it will not be completely blocked at certain angles like linearly polarized light. Regardless of the viewing angle, light can be guaranteed to pass through polarized sunglasses, thus enabling display 5 to achieve a 360-degree viewing angle.

[0039] The biaxial stretching apparatus applies uniform tension simultaneously in both the transverse and longitudinal directions of the polycarbonate film layer 32, ensuring uniform stretching of the film in both directions. This is not only significant for improving optical performance but also positively impacts the structural stability and uniformity of the film. Uniform stretching results in a more uniform film thickness after stretching, avoiding localized weak or excessively thick areas caused by uneven stretching, and reducing potential fluctuations in optical performance and instability in physical properties due to thickness differences. Simultaneously, uniform stretching also makes the mechanical properties of the film more balanced in different directions, enhancing its tear and deformation resistance, helping to extend its service life during use, ensuring it maintains good performance even under long-term use and different environments, and providing continuous and stable protection and light conversion functions for the display 5.

[0040] The optical-grade silicone pressure-sensitive adhesive layer 33 is used to bond the polycarbonate film layer 32 to the second release film 2. The silicone pressure-sensitive adhesive has extremely high transparency and flexibility, enabling a strong bond without damaging the display screen surface. Furthermore, the silicone pressure-sensitive adhesive also exhibits excellent temperature resistance and aging resistance, maintaining stable performance in various extreme environments.

[0041] The optical-grade acrylic resin layer 31 firmly adheres the polycarbonate film layer 32 to the first release film 1 through intermolecular physical adsorption. Similarly, the optical-grade silicone pressure-sensitive adhesive layer 33 tightly bonds the polycarbonate film layer 32 to the second release film 2 through intermolecular forces. This multi-layered bonding method not only ensures a tight bond between the layers but also enhances the stability and reliability of the overall structure.

[0042] The first release film 1 and the second release film 2 are typically produced using a single-sided coating process, ensuring good release properties on one side and a smooth, flat surface on the other for easy subsequent processing. The polycarbonate film layer 32 is prepared using a biaxial stretching process, resulting in a uniform thickness and excellent optical properties. The optical-grade acrylic resin layer 31 and the optical-grade silicone pressure-sensitive adhesive layer 33 require precise control of their formulation and manufacturing processes to ensure the quality and performance of the final product.

[0043] UV and blue light blockers can be added to the 31-layer optical-grade acrylic resin layer to further enhance the protective performance of the AB film. Commonly used UV and blue light blockers include inorganic nanoparticles such as zinc oxide and titanium dioxide, as well as organic compounds such as UV absorber UV-9 and blue light inhibitor TINUVIN 479DW. These additives not only effectively block harmful UV and blue light but also extend the service life of the AB film.

[0044] Another optimization design involves incorporating similar UV and blue light blocking agents into the optical-grade silicone pressure-sensitive adhesive layer 33. This strengthens screen protection on multiple levels, ensuring good light transmittance and color reproduction even after prolonged use.

[0045] Another important design optimization is adjusting the thickness of the 31-layer optical-grade acrylic resin layer. Depending on the specific application, the thickness can be set between 15μm and 1000μm. Thinner acrylic resin layers are suitable for lightweight designs and portable devices, while thicker layers are better suited for large-size displays, providing better bond strength and impact resistance.

[0046] The first release film 1 and the second release film 2 serve as outer protective layers, ensuring that the AB adhesive layer 3 is not damaged during production and transportation. The optical-grade acrylic resin layer 31 and the optical-grade silicone pressure-sensitive adhesive layer 33 serve as intermediate layers, respectively responsible for bonding the polycarbonate film layer 32 to the first release film 1 and the second release film 2, forming a robust and transparent three-layer structure. The polycarbonate film layer 32, located at the center, plays a crucial role in light conversion, transforming linearly polarized light into circularly polarized light, significantly improving display quality and viewing comfort.

[0047] The implementation principle of this embodiment is as follows: through reasonable design and material selection, the AB film not only possesses excellent optical and mechanical properties, but also effectively solves the problem of obstructed vision caused by polarizers. Especially for in-vehicle displays, the application of this AB film greatly enhances driving safety, ensuring that the driver can clearly view screen information under any lighting conditions.

[0048] Example 2

[0049] Reference Figure 2 The difference between this embodiment and the previous embodiment is that this embodiment provides a display protection structure, including a protective layer 4 and an AB adhesive layer 3 bonded to the protective layer 4. The specific structure of the AB adhesive layer 3 is the same as that of the AB adhesive layer 3 in Embodiment 1, but the protective layer 4 uses optical-grade transparent tempered glass with a thickness of 0.1mm-5.0mm. This design not only improves the screen's wear resistance and scratch resistance but also maintains high light transmittance, ensuring the quality of the screen image.

[0050] Specifically, protective layer 4 is made of optical-grade transparent tempered glass, characterized by high strength and high hardness. The tempered glass undergoes a special heat treatment process, resulting in uniform internal stress distribution, enabling it to withstand significant impact without easily breaking. Simultaneously, the surface of the tempered glass is polished, exhibiting high gloss and smoothness, effectively reducing glare and improving viewing comfort.

[0051] The structure and function of AB adhesive layer 3 are exactly the same as those of AB adhesive layer 3 in Example 1. Optical grade acrylic resin layer 31 is used to bond polycarbonate film layer 32 to protective layer 4, and optical grade silicone pressure-sensitive adhesive layer 33 is used to bond polycarbonate film layer 32 to display 5. This dual bonding method ensures the stability and reliability of the entire structure.

[0052] The protective layer 4 is connected to the polycarbonate film layer 32 of the AB adhesive layer 3 via an optical-grade acrylic resin layer 31, and then contacts the surface of the display 5 via an optical-grade silicone pressure-sensitive adhesive layer 33. This multi-layered bonding structure not only ensures a tight bond between the layers, but also enhances the overall structure's shock resistance and impact resistance.

[0053] The thickness of protective layer 4 ranges from 0.1mm to 5.0mm, allowing selection based on the specific application. A thinner protective layer 4 is suitable for lightweight designs and mobile devices, while a thicker layer is better suited for large displays, providing enhanced protection. The tempered glass surface undergoes fine grinding and polishing to eliminate minor imperfections, ensuring optimal screen visibility.

[0054] A blue light blocking layer 6 can be added inside the protective layer 4, positioned between the optical-grade silicone pressure-sensitive adhesive layer 33 and the polycarbonate film layer 32. The blue light blocking layer 6 is primarily made of polymer materials containing blue light inhibitors, effectively filtering out harmful blue light components and protecting the user's eye health. Common synthetic blue light inhibitors include xanthones and triazine compounds, while naturally extracted blue light inhibitors include plant pigments such as lutein and zeaxanthin.

[0055] Another optimized design involves adding an anti-fingerprint coating to the back of the protective layer 4. This anti-fingerprint coating is typically made of hydrophobic and oleophobic fluorocarbon resin, effectively preventing fingerprints and other smudges from leaving marks on the screen, keeping it clean and aesthetically pleasing.

[0056] Another important design optimization is adjusting the light transmittance of protective layer 4. To ensure the clarity and brightness of the screen image, the light transmittance of protective layer 4 should be greater than 85%. This can be achieved by optimizing the manufacturing process and surface treatment process of tempered glass. For example, using raw materials with low iron content to make tempered glass can reduce the appearance of yellow tones and improve light transmittance; by applying a nano-coating to the surface of tempered glass, reflectivity can be further reduced and image quality improved.

[0057] The implementation principle of this embodiment is as follows: The display protection structure not only has excellent protective performance, but the outermost protective layer 4 also protects the screen from external damage. The AB adhesive layer 3, through the optical-grade acrylic resin layer 31 and the optical-grade silicone pressure-sensitive adhesive layer 33, tightly connects the protective layer 4 to the display 5. The polycarbonate film layer 32, located in the middle, improves the screen's visibility and viewing comfort by changing the polarization state of the incident light. This multi-layered protection and optimized design makes the entire display protection structure both robust and durable, and possesses excellent optical performance. It also effectively improves the screen's viewing experience. It is particularly suitable for automotive displays and other scenarios requiring high reliability and high visibility.

[0058] Example 3

[0059] The difference between this embodiment and the previous embodiment is that this embodiment provides a temperature-adaptive display protection structure, including a protective layer 4 and an AB adhesive layer 3 bonded to the protective layer 4. The specific structure of the AB adhesive layer 3 is the same as that of the AB adhesive layer 3 in Embodiment 1, but the protective layer 4 uses a material with temperature-responsive characteristics, which can adjust its rigidity and flexibility at different temperatures to adapt to the usage requirements under different environmental conditions.

[0060] Specifically, the material of protective layer 4 is an optical-grade transparent polymer with temperature-responsive properties, such as polyurethane elastomer. This type of material exhibits high rigidity at low temperatures, resisting impacts and scratches; while at higher temperatures it becomes more flexible, facilitating adhesion to curved screens or other irregularly shaped screens. This characteristic allows protective layer 4 to maintain good protective performance and visual effects under various climatic conditions.

[0061] The implementation principle of this embodiment is as follows: through reasonable structural design and material selection, the display protection structure of this utility model not only has good protective performance, but also can adapt to the usage requirements under different temperature conditions. It is particularly suitable for vehicle-mounted displays and other scenarios that need to be used in harsh environments.

[0062] Example 4

[0063] The difference between this embodiment and the previous embodiment is that this embodiment provides a waterproof display protection structure, including a protective layer 4 and an AB adhesive layer 3 bonded to the protective layer 4. The specific structure of the AB adhesive layer 3 is the same as that of the AB adhesive layer 3 in Embodiment 1, but the protective layer 4 uses a waterproof material, such as modified epoxy resin. This design not only improves the waterproof performance of the screen but also maintains high light transmittance, ensuring the quality of the screen image.

[0064] Specifically, the protective layer 4 is made of modified epoxy resin, which has high water resistance and good light transmittance. The modified epoxy resin undergoes special treatment to maintain stable performance under different humidity conditions, preventing moisture from penetrating into the screen and causing damage. At the same time, the surface of the modified epoxy resin is polished, resulting in high gloss and smoothness, effectively reducing glare and improving viewing comfort.

[0065] The implementation principle of this embodiment is as follows: Through reasonable structural design and material selection, the display protection structure of this utility model not only has good protective performance but also effectively resists the effects of humid environments. It is particularly suitable for vehicle-mounted displays and other scenarios that need to be used in humid environments. Compared with the traditional single protective layer scheme, the display protection structure of this utility model has significantly improved its overall performance and is expected to be widely used in the future.

[0066] Example 5

[0067] The difference between this embodiment and the previous embodiment is that this embodiment provides a display protection structure with antibacterial function, including a protective layer 4 and an AB adhesive layer 3 bonded to the protective layer 4. The specific structure of the AB adhesive layer 3 is the same as that of the AB adhesive layer 3 in Embodiment 1, but the protective layer 4 uses a material with antibacterial properties, such as silver ion-doped polyurethane elastomer. This design not only improves the antibacterial performance of the screen but also maintains high light transmittance, ensuring the quality of the screen image.

[0068] Specifically, the protective layer 4 is made of silver ion-doped polyurethane elastomer, which has high antibacterial properties and good light transmittance. The silver ion-doped polyurethane elastomer undergoes special treatment to maintain stable antibacterial effects in various bacterial environments, preventing bacterial growth and infection. Simultaneously, the surface of the silver ion-doped polyurethane elastomer is polished, resulting in high gloss and smoothness, effectively reducing reflections and improving viewing comfort.

[0069] The implementation principle of this embodiment is as follows: through reasonable structural design and material selection, the display protection structure of this utility model not only has good protective performance, but also effectively prevents infection caused by bacterial growth. It is particularly suitable for medical equipment and other scenarios requiring high hygiene standards.

[0070] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
