Description

Technical Field

[0001] This utility model relates to the field of display technology, and in particular to a glass film layer with a smooth layer and a coated cover plate. Background Technology

[0002] In recent years, electronic products have become increasingly popular and their functions have become more diversified, leading to a greater demand for glass substrates. While traditional glass substrates possess basic transparency and protection, they still have shortcomings in terms of abrasion resistance, light transmittance, stain resistance, and functionality. Especially in the field of consumer electronics such as smartphones and tablets, users have increasingly higher requirements for the appearance, feel, and functional experience of devices, placing higher demands on glass substrates. Currently, the coatings prepared from existing glass substrates are insufficient to meet user needs in terms of hardness, abrasion resistance, and light transmittance.

[0003] For example, Chinese utility model patent (CN208136093U) discloses a multi-layer coated glass, including a glass substrate. The key technical points are: an anti-reflective film layer and a hydrophobic self-cleaning film layer are respectively provided on both sides of the glass substrate. The anti-reflective film layer includes a first anti-reflective film layer and a second anti-reflective film layer stacked together, with the first anti-reflective film layer disposed on the side closest to the glass substrate. 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.

[0004] However, when the inventors implemented this device, they found the following defects: it is still difficult to meet the requirements in terms of hardness, wear resistance, and light transmittance. Utility Model Content

[0005] Therefore, it is necessary to address the aforementioned technical problems by providing a glass film layer with a smoothing layer. This is achieved by sequentially stacking a titanium nitride layer, an acrylic resin layer, and a samarium fluoride film layer on the upper surface of the glass substrate from top to bottom. The titanium nitride and acrylic resin layers together provide high hardness and wear resistance, protecting the glass surface from scratches and abrasions. Then, the samarium fluoride coating layer reduces light reflection and increases light transmittance, making the image clearer and brighter. This multi-layer structure design not only enhances physical protection but also adds temperature indication functionality and better aesthetics to the glass substrate, meeting the demand for high-quality cover materials for electronic products.

[0031] For details, please refer to Figure 1-3 The glass film layer with a smooth layer specifically includes:

[0032] The glass substrate 100 and the wear-resistant smooth film layer 200; wherein the wear-resistant smooth film layer 200 covers one side of the surface of the glass substrate 100, and the wear-resistant smooth film layer 200 includes a samarium fluoride film layer 210 for reducing light reflection, and the samarium fluoride film layer 210 covers the upper surface of the glass substrate 100.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] Example 1

[0039] Please refer to Figure 1-3A glass film layer with a smoothing layer includes a glass substrate 100 and a wear-resistant smoothing film layer 200; wherein the wear-resistant smoothing film layer 200 covers one side surface of the glass substrate 100, and the wear-resistant smoothing film layer 200 includes a samarium fluoride film layer 210 for reducing light reflection, and the samarium fluoride film layer 210 covers the upper surface of the glass substrate 100.

[0040] The wear-resistant smooth film layer 200 also includes an acrylic resin layer 220 for improving the adhesion quality of subsequent coatings and a titanium nitride layer 230 for reducing wear from hard objects. The acrylic resin layer 220 covers the upper surface of the samarium fluoride film layer 210, and the titanium nitride layer 230 covers the upper surface of the acrylic resin layer 220.

[0041] Through the above structural design, the titanium nitride layer 230 is disposed on the outermost layer of the glass substrate 100, providing high hardness and excellent wear resistance, effectively preventing scratches and wear during daily use. Simultaneously, titanium nitride also has good corrosion resistance and optical transmittance, without affecting the visual effect of the glass. The acrylic resin layer 220 is located immediately below the titanium nitride layer 230. Acrylic resin has good adhesion and weather resistance, further enhancing the overall stability and durability of the coating. It also serves as a smoothing layer, improving the adhesion quality of subsequent coatings. The samarium fluoride coating layer is located below the acrylic resin layer 220, directly attached to the glass substrate. The samarium fluoride coating has excellent anti-reflection properties, reducing light reflection on the glass surface and improving light transmittance.

[0042] By sequentially stacking a titanium nitride layer 230, an acrylic resin layer 220, and a samarium fluoride film layer 210 on the upper surface of the glass substrate 100 from top to bottom, the titanium nitride layer 230 and the acrylic resin layer 220 together provide high hardness and wear resistance, protecting the glass surface from scratches and abrasions. Then, the samarium fluoride coating layer can reduce light reflection and improve light transmittance, making the picture clearer and brighter. This multi-layer structure design not only enhances physical protection capabilities but also adds temperature indication function and better aesthetics to the glass substrate 100, meeting the demand for high-quality electronic product cover materials.

The ink region 300 is a thermochromic ink layer. Specifically, a base layer 400 is provided at the bottom of the ink region 300. The thickness of the ink region 300 is 8~10µm.

[0044] Through the above structural design, the ink area 300 has a thickness of 8~10nm and is located on the outer periphery of the bottom surface of the glass substrate 100. The thermochromic ink layer can change color according to temperature changes, providing an intuitive temperature indication function, which is particularly suitable for electronic products that need to monitor temperature changes. On the upper surface of the glass substrate 100, a titanium nitride layer 230, an acrylic resin layer 220, and a samarium fluoride film layer 210 are stacked sequentially from top to bottom. The titanium nitride layer 230 and the acrylic resin layer 220 together provide high hardness and wear resistance, protecting the glass surface from scratches and wear. Then, the samarium fluoride coating layer can reduce light reflection and improve light transmittance, making the picture clearer and brighter. This multi-layer structure design not only enhances the physical protection capability, but also adds temperature indication function and better aesthetics to the glass substrate 100, meeting the demand for high-quality electronic product cover materials.

[0047] Through the above structural design, the tin layer is located right below the thermochromic ink layer, with a thickness of 20-30nm. As a protective layer, the tin layer can effectively prevent the thermochromic ink from being scratched or damaged during manufacturing, transportation and use, thereby maintaining its good color-changing performance and appearance. It not only enhances the physical protection capability, but also adds temperature indication function and better aesthetics to the glass substrate 100, meeting the demand for high-quality electronic product cover materials.

[0052] Specifically, the length and width dimensions of the samarium fluoride film layer 210, the titanium nitride layer 230, and the acrylic resin layer 220 are all the same.

[0053] Through the above structural design, a titanium nitride layer 230, an acrylic resin layer 220, and a samarium fluoride film layer 210 are sequentially stacked from top to bottom on the upper surface of the glass substrate 100. The titanium nitride layer 230 and the acrylic resin layer 220 together provide high hardness and wear resistance, protecting the glass surface from scratches and abrasions.
