Description

Technical Field

[0001] This utility model relates to the field of display technology, and in particular to a stacked film layer and a coated cover plate that enhances durability and stain resistance. Background Technology

[0002] With increasingly fierce technological innovation and market competition, the demand for electronic display devices is constantly growing, and the performance requirements for cover plates are also becoming higher. As a key component for protecting the screen and improving user experience, the cover plate plays an important role in preventing scratches, wear, dust, and oil. Currently, commonly used cover plate materials on the market, such as ordinary glass or plastic, are prone to scratches, wear, and discoloration when facing complex and changing usage environments.

[0003] The shortcomings of these traditional materials severely impact product lifespan, aesthetics, and user experience. This is especially true for high-end electronic products, where users have higher demands for the wear resistance, optical performance, and overall aesthetics of the cover glass. Therefore, developing a novel cover glass coating that combines high hardness, wear resistance, chemical corrosion resistance, stain resistance, and high transparency has become a focus of industry attention.

[0004] For example, Chinese utility model patent (CN208136093U) discloses a multi-layer coated glass, including a cover glass. The key technical points are: an anti-reflective coating layer and a hydrophobic self-cleaning coating layer are respectively provided on both sides of the cover glass. The anti-reflective coating layer includes a first anti-reflective coating layer and a second anti-reflective coating layer stacked together, with the first anti-reflective coating layer disposed on the side closer to the cover glass. This utility model's multi-layer coated glass applies novel materials and technologies to coated glass, simultaneously possessing high light transmittance and self-cleaning function.

[0005] However, in implementing this device, the inventors discovered the following drawbacks: the shortcomings of these traditional materials severely affect the product's lifespan, aesthetics, and user experience. Especially for high-end electronic products, users have higher requirements for the cover's wear resistance, optical performance, and overall aesthetics. Utility Model Content

Simultaneously, the ink layer used in the back frame area is a combination of a photosensitive color-changing ink layer and a protective layer of aminopropyltriethoxysilane, which not only imparts dynamic color changes to the cover glass but also improves the durability of the ink layer and its adhesion to the cover glass, enhancing the cover glass's aesthetics and durability. This layered structural design fully leverages the advantages of different materials, working together to achieve comprehensive optimization of the cover glass in terms of wear resistance, optical performance, aesthetics, and corrosion resistance.

[0043] Example 1

[0044] Please refer to Figure 1-3 A stacked film layer for enhanced durability and antifouling properties, comprising:

[0045] Cover glass 100, which includes a rear frame area and a front surface area;

[0046] The stacked film layer assembly 200 is deposited on the front surface area of ​​the cover glass 100, and the stacked film layer assembly 200 includes, from top to bottom, a durable layer 210, a reinforcing layer 220 and an anti-fouling layer 230, with the anti-fouling layer 230 disposed on the front surface area of ​​the cover glass 100.

[0047] Ink layer 300 is disposed in the back frame area of ​​cover glass 100;

[0048] Protective layer 400 is disposed on the bottom surface of ink layer 300.

[0049] Through the above structural design, the stacked film layer group 200 is mainly based on a high-transmittance, high-strength substrate, ensuring structural strength and optical performance. The anti-fouling layer 230 is a wear-resistant and corrosion-resistant niobium nitride layer, reinforced by a stable and conductive aluminum layer, and the durable layer 210 is a chemically resistant and low-friction polysulfonated fluoride layer, deposited sequentially to form a three-layer coating system that jointly resists external damage and enhances stability and protective performance. Meanwhile, the ink layer 300 used in the back frame area is a combination of a photosensitive color-changing ink layer 300 and a protective layer 400 of aminopropyltriethoxysilane, which not only gives the cover glass 100 dynamic color changes but also improves the durability of the ink layer 300 and its adhesion to the cover glass 100, enhancing the aesthetics and durability of the cover glass 100. This layered structural design fully utilizes the advantages of different materials, working together to achieve comprehensive optimization of the cover glass 100 in terms of wear resistance, optical performance, aesthetics, and corrosion resistance.

[0050] Specifically, the thickness of the protective layer 400 is 10-20 nm.

[0051] Through the above structural design, in this embodiment of the utility model, the thickness of the protective layer 400 is 10nm, but it can also be other thicknesses depending on different needs.

[0052] Specifically, the protective layer 400 is an aminopropyltriethoxysilane layer.

[0053] Through the above structural design, the aminopropyltriethoxysilane layer, as the protective layer 400 of the ink layer 300, effectively prevents the ink layer 300 from being scratched due to its excellent adhesion and corrosion resistance. At the same time, it enhances the bonding force between the ink layer 300 and the cover glass 100, thereby improving the overall durability of the product.

[0054] Specifically, the thickness of ink layer 300 is 10-12 μm. Specifically, the material used to make ink layer 300 is photosensitive color-changing ink.

[0055] Through the above structural design, the ink layer 300300 is a photosensitive color-changing ink with a thickness of 10-12μm. It changes color according to changes in light or temperature, increasing the product's interest and aesthetics.

[0056] Example 2

[0057] The stacked film layer with enhanced durability and antifouling properties provided in Example 1 is further optimized, specifically, as follows: Figure 1-3 As shown, the thickness of the durability layer 210 is 50-80nm, the thickness of the reinforcement layer 220 is 30-60nm, and the thickness of the anti-fouling layer 230 is 20-40nm.

[0058] Through the above structural design, the stacked film layer group 200 is mainly based on a high-transmittance, high-strength substrate, ensuring structural strength and optical performance. The anti-fouling layer 230 is a wear-resistant and corrosion-resistant niobium nitride layer, reinforced by a stable and conductive aluminum layer, and the durable layer 210 is a chemically resistant and low-friction polysulfonated fluoride layer, deposited sequentially to form a three-layer coating system that jointly resists external damage and enhances stability and protective performance. Meanwhile, the ink layer 300 used in the back frame area is a combination of a photosensitive color-changing ink layer 300 and a protective layer 400 of aminopropyltriethoxysilane, which not only gives the cover glass 100 dynamic color changes but also improves the durability of the ink layer 300 and its adhesion to the cover glass 100, enhancing the aesthetics and durability of the cover glass 100. This layered structural design fully utilizes the advantages of different materials, working together to achieve comprehensive optimization of the cover glass 100 in terms of wear resistance, optical performance, aesthetics, and corrosion resistance.

[0059] Example 3

[0060] The stacked film layer with enhanced durability and antifouling properties provided in Example 1 or 2 is further optimized, such as... Figure 1-3 As shown, the antifouling layer 230 is a niobium nitride layer.

[0061] Through the above structural design, niobium nitride has high hardness, high wear resistance and good chemical stability. As a base layer, it can effectively improve the scratch resistance of the cover plate and provide a stable adhesion base for the subsequent coating layer.

[0062] Specifically, the reinforcing layer 220 is an aluminum layer.

[0063] Through the above structural design, the aluminum layer has good reflectivity and conductivity. In addition, its excellent metallic properties help to improve the overall performance stability of the coating layer.

[0064] Specifically, the durable layer 210 is a polysulfonated fluorinated ethylene layer.

[0065] Through the above structural design, as the outermost layer, polysulfonated fluoride provides excellent protection for the coating layer with its excellent chemical corrosion resistance, low coefficient of friction and waterproof performance, thereby enhancing the overall durability and stain resistance of the coating layer.

[0066] This utility model embodiment also provides a coated cover plate, which includes a stacked film layer as described above to enhance durability and stain resistance.

[0067] The combination of niobium nitride and polysulfonated fluoride significantly improves the hardness and abrasion resistance of the glass surface, effectively preventing scratches and wear, and extending the service life of the cover glass. The aluminum layer primarily plays a stabilizing role in this structure, but the high light transmittance and low refractive index of the niobium nitride and polysulfonated fluoride layers help reduce light reflection and scattering, enhancing the visual effect. The dynamic color change of the photosensitive color-changing ink layer 300 adds a unique visual effect to the product, increasing its appeal and interest. The aminopropyltriethoxysilane layer effectively prevents scratches on the ink layer 300 while strengthening the bond between the ink layer 300 and the cover glass 100, improving the overall durability of the product. By combining multiple high-performance materials, the stacked film layer assembly 200 not only achieves basic protective functions but also incorporates additional functions such as color changing and scratch resistance, meeting diverse market demands.

[0068] The process of using the stacked film layer and coated cover plate that enhances durability and stain resistance provided by this utility model is as follows:

[0069] The stacked film layer group 200 primarily uses a high-transmittance, high-strength substrate as its foundation, ensuring structural strength and optical performance. The anti-fouling layer 230 is a wear-resistant and corrosion-resistant niobium nitride layer, reinforced by a stable and conductive aluminum layer. The durable layer 210 is a chemically resistant, low-friction polysulfonated fluoride layer, deposited sequentially to form a three-layer coating system that collectively resists external damage, enhancing stability and protective performance. Simultaneously, the ink layer 300 used in the back bezel area is a combination of a photosensitive color-changing ink layer 300 and a protective layer 400 consisting of an aminopropyltriethoxysilane layer. This not only imparts dynamic color changes to the cover glass 100 but also improves the durability of the ink layer 300 and its adhesion to the cover glass 100, enhancing the cover glass 100's aesthetics and durability. This layered structural design fully leverages the advantages of different materials, working together to achieve comprehensive optimization of the cover glass 100 in terms of wear resistance, optical performance, aesthetics, and corrosion resistance.
