Technical Field

[0001] The utility model relates to the technical field of display screen cover plates, and in particular to a sun-proof coating cover plate and a display screen comprising the same. Background Art

[0002] With technological advancements, glass cover panels are increasingly being used in electronics, outdoor display screens, and automotive displays. However, traditional glass cover panels face performance bottlenecks when dealing with complex environments (such as high temperature, humidity, and UV radiation). In particular, their optical performance, thermal management capabilities, and durability need to be improved. Therefore, an innovative glass cover coating technology is needed to enhance the optical performance, thermal protection, and long-term stability of the cover panels through coating, thereby meeting the modern industry's demand for high-performance glass cover panels. Utility Model Content

[0003] The purpose of the present invention is to provide a sun-proof coating cover and a display screen including the same, aiming to partially solve the above-mentioned technical problems.

[0004] Specifically, the specific technical solution of the utility model is: a sun-proof coated cover plate, including a cover plate body, a chromium layer, an aluminum reflective layer, and a tantalum oxide protective layer stacked in sequence on the front side of the cover plate body, wherein the thickness of the chromium layer is 10nm~18nm, the thickness of the aluminum reflective layer is 20nm~30nm, and the thickness of the tantalum oxide protective layer is 30nm~45nm.

[0005] As a preferred technical solution, the aluminum reflective layer is configured to include a multi-layer structure, and the thickness of the multi-layer aluminum reflective layer after stacking is 20 nm to 30 nm.

[0006] As a preferred technical solution, the tantalum oxide protective layer is configured to include a multi-layer structure, and the thickness of the multi-layer tantalum oxide protective layer after stacking is 30 nm to 45 nm.

[0007] As a preferred technical solution, a cover bottom layer is provided on the back of the cover body, and the cover bottom layer is a gray ink layer or a black ink layer.

[0008] As a preferred technical solution, the cover bottom layer is made by screen printing technology, and the thickness of the cover bottom layer is 10 to 30 μm.

[0009] As a preferred technical solution, a UV glue transfer layer and an ink printing layer made by screen printing technology are provided between the cover bottom layer and the back side of the cover plate body.

[0010] As a preferred technical solution, the UV glue transfer layer is arranged above the ink printing layer.

[0011] As a preferred technical solution, the cover plate body is a glass cover plate, and the thickness of the glass cover plate is 75 to 80 nm.

[0012] As a preferred technical solution, the glass cover is 2.5D or 3D glass, and the four edges are downwardly inclined or curved surfaces.

[0013] On the other hand, a display screen is also provided, comprising the above-mentioned sun-proof coated cover plate. This display screen significantly improves the optical, thermal protection and weather resistance of the glass cover plate, providing reliable protection for the application of the glass cover plate in various complex environments.

[0014] The beneficial effect of the present invention is that the present invention constructs a multi-layer coating structure on the surface of the glass cover plate. First, a thin and uniform chromium layer is deposited on the surface of the glass substrate as an adhesion layer. Its excellent mechanical strength and chemical stability provide a solid foundation for the entire coating system. Subsequently, an aluminum layer is plated on the chromium layer. This layer serves as a high-reflection layer. Through its high-reflection properties, it effectively reduces light transmission, reduces the temperature inside the cover plate, and achieves the effect of sun protection and cooling. Finally, a tantalum oxide protective layer is covered. By utilizing its excellent chemical stability and corrosion resistance, the aluminum layer is protected from oxidation erosion, thereby extending the service life of the coating layer. The design of this multi-layer coating structure not only enhances the adhesion between the coating layer and the substrate, but also significantly improves the optical, thermal protection and weather resistance of the glass cover plate, providing reliable protection for the application of the glass cover plate in a variety of complex environments.

[0024] Example

[0025] like Figure 1 Figure 1 shows a schematic diagram of the sunscreen coating cover structure proposed in this embodiment. It includes a cover body 1, with a chromium layer 2, an aluminum reflective layer 3, and a tantalum oxide protective layer 4 laminated on the front side. The chromium layer 2 has a thickness of 10 nm to 18 nm, the aluminum reflective layer 3 has a thickness of 20 nm to 30 nm, and the tantalum oxide protective layer 4 has a thickness of 30 nm to 45 nm. The chromium layer 2 acts as an adhesion layer, enhancing the adhesion of subsequent coatings to the glass substrate. Chromium has excellent mechanical strength and chemical stability, helping to ensure the stability and durability of the entire coating layer.

[0026] Preferably, the aluminum reflective layer 3 comprises a multi-layer structure, which can be deposited in multiple layers. The thickness of the stacked aluminum reflective layers 3 is 20 nm to 30 nm. The highly reflective aluminum layer can reduce light transmission through the cover plate, thereby reducing the temperature of the product surface within the cover plate, particularly from sunlight, and thus providing sun protection.

[0027] Preferably, the tantalum oxide protective layer 4 is configured to include a multi-layer structure, and the thickness of the stacked tantalum oxide protective layers 4 is 30 nm to 45 nm. As a protective layer, the tantalum oxide layer can prevent the aluminum layer from being oxidized, thereby improving the corrosion resistance and stability of the coating layer.

[0028] Further, such as Figure 2 As shown, the back of the cover body 1 is provided with a cover bottom layer 5, which is a gray ink layer or a black ink layer. The cover bottom layer 5 is made using screen printing technology and has a thickness of 10 to 30 μm, which can provide a light-shielding effect.

[0029] Furthermore, a UV glue transfer layer 6 and an ink printing layer 7 made by screen printing technology are provided between the bottom cover layer 5 and the back of the cover body 1. The UV glue transfer layer 6 is provided above the ink printing layer 7.

[0030] The cover body 1 is a glass cover with a thickness of 75 to 80 nm, and can be 2.5D or 3D glass, with four edges being downwardly inclined or curved.

[0031] Applying the above-mentioned sun-proof coated cover plate to the display screen can improve the optical performance, thermal protection capability and long-term stability of the display screen, and meet the demand of modern industry for high-performance glass cover plates.

[0032] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail.
