[0035] Embodiment One

[0036] Referring to Figure 1 The coating cover plate provided in the present embodiment includes a cover plate 1, the cover plate 1 has a front surface and a back surface, the front surface of the cover plate 1 is coated with a substrate layer 2, an intermediate layer and a surface layer 5 in sequence, the intermediate layer is a composite layer and includes at least one europium titanate layer 4 and at least one reinforcing layer 3, the substrate layer 2 is used to enhance adhesion, the reinforcing layer 3 is used to enhance the mechanical properties of the cover plate 1, and the surface layer 5 is used to enhance the optical properties of the cover plate 1.

[0037] The cover plate 1 is a transparent glass plate or a transparent acrylic plate. Of course, the cover plate 1 can also be made of a flexible transparent material, so that the cover plate 1 can be folded, thereby being applicable to flexible and foldable display device accessories. The cover plate 1 can be made of transparent, soft and foldable materials such as UTG (Ultra Thin Glass), CPI (Colorless Polyimide) and PET (Polyethylene Terephthalate).

[0038] Embodiment Two

[0039] Referring to Figure 1 The coating cover plate provided in the present embodiment includes a cover plate 1, the cover plate 1 has a front surface and a back surface, the front surface of the cover plate 1 is coated with a substrate layer 2, an intermediate layer and a surface layer 5 in sequence, the intermediate layer is a composite layer and includes at least one europium titanate layer 4 and at least one reinforcing layer 3, the substrate layer 2 is used to enhance adhesion, the reinforcing layer 3 is used to enhance the mechanical properties of the cover plate 1, and the surface layer 5 is used to enhance the optical properties of the cover plate 1.

[0040] The europium titanate layer 4 is a functional oxide material with a perovskite structure, which provides a stable substrate with high dielectric constant and good insulation, optimizes light transmission and enhances the adhesion of subsequent coating layers, thereby stabilizing the substrate, enhancing adhesion and optimizing optical properties. The chromium trioxide layer 7 is an inorganic compound with excellent chemical stability, wear resistance and high hardness. The intermediate layer uses the chromium trioxide layer 7 as the main component to protect the inner layer through its excellent wear resistance and corrosion resistance. The yttrium chromium oxide is a perovskite type transition metal oxide and belongs to a composite oxide material, which is composed of rare earth element yttrium and transition metal chromium and has excellent wear resistance and corrosion resistance.

[0041] Europium titanate exhibits excellent fluorescence properties and is often used as a luminescent material. In its Eu²⁺ state, it may emit blue light or other broadband emission, which is beneficial for its application in lighting and display technologies. Therefore, the europium titanate layer 4 endows the cover plate 1 with unique luminescent or fluorescent effects, bringing rich colors and gloss effects to the cover plate 1, allowing the cover plate 1 to exhibit unique aesthetic effects under different lighting conditions, thus enhancing the aesthetics and functionality of the cover plate 1.

[0042] Please refer to Figure 3 To further improve the wear resistance, corrosion resistance and optical performance of the cover plate 1, multiple layers of chromium trioxide layer 7 and europium titanate layer 4 can be alternately deposited to form a composite layer on the front side of the cover plate 1. In this example, three layers of chromium trioxide layer 7 and three layers of europium titanate layer 4 are each deposited.

[0043] The combined use of yttrium chromium oxide layer 8 and chromium trioxide layer 7 improves the wear resistance and corrosion resistance of cover plate 1, while strontium titanate layer 6 stabilizes the substrate, jointly enhancing the overall durability of cover plate 1 and extending its service life. The luminescent or fluorescent effect of europium titanate layer 4 allows cover plate 1 to exhibit unique aesthetic effects under different lighting conditions. Furthermore, europium titanate layer 4 adds specific functionalities to cover plate 1, such as luminous indication and environmental response. The multi-layer coating structure brings rich color and gloss effects. In this example, the design of the multi-layer coating structure optimizes the transmission, reflection, and scattering of light to achieve specific visual effects, such as increasing light transmittance and reducing reflection.

[0046] The silicon resin has good adhesion and weather resistance, and serves as the base layer 2 of the coating layer, so that the coating layer can be firmly attached to the cover plate 1. The boron carbide is a material with extremely high hardness and good wear resistance, and can significantly improve the scratch resistance and wear resistance of the cover plate 1. The europium titanate has characteristic luminescence performance, especially in the red region (transition of Eu3+). The europium titanate can exhibit excellent fluorescence characteristics and is often used as a luminescent material. It may exhibit blue light or other broadband emission in the Eu2+ state, which helps its application in lighting and display technology, so that the europium titanate layer 4 endows the cover plate 1 with unique luminescence or fluorescence effect, brings rich color and luster effect to the cover plate 1, and enables the cover plate 1 to exhibit unique aesthetic effect under different illumination conditions, thereby enhancing the aesthetic property and functionality of the cover plate 1. The niobium pentoxide is a high-refractive material and can be used to form an anti-reflection layer to reduce reflection loss of light on the surface of the cover plate 1 and improve the light transmittance.

[0047] The working principle of the coated cover plate is as follows: the base layer 2 improves the adhesion of the intermediate layer, the intermediate layer adopts the combined layer containing the europium titanate layer 4, the mechanical properties of the cover plate 1 in terms of wear resistance and corrosion resistance are improved, the europium titanate layer 4 can endow the cover plate 1 with unique luminescence or fluorescence effect, the aesthetic property and functionality are enhanced, the surface layer 5 strengthens the mechanical properties of the cover plate 1 while maintaining the overall optical properties of the cover plate 1, the overall durability of the cover plate 1 is improved, the service life is prolonged, the multi-layer coating structure is adopted to accurately control the type, thickness and arrangement order of each layer of material, the perfect balance of optical properties, mechanical properties and aesthetic property is realized, the cover plate 1 brings unprecedented use experience and value, and higher quality and longer service life of the cover plate 1 are provided for the fields of electronic products, building glass and automobile windows.
