[0035] Zirconium nitride has extremely high hardness and wear resistance, can effectively resist scratches and wear, and protect the film-coated layer below from damage. The atomic bonding force in the crystal structure of zirconium nitride is very strong, which makes it have high hardness. This high hardness enables zirconium nitride to effectively resist deformation and wear when it is subjected to external friction and scratching. At the same time, the internal microstructure of zirconium nitride also makes it have good wear resistance, which enables it to maintain its performance stability during a long period of friction.

[0036] Polysulfonated fluorinated ethylene has excellent chemical stability and wear resistance, which can further enhance the durability of the film-coated layer and at the same time provide certain anti-fouling and anti-fingerprint effects. The molecular structure of polysulfonated fluorinated ethylene contains stable chemical bonds, which makes it have excellent chemical stability and is not prone to reaction with external chemical substances. The arrangement of its molecular chains and surface properties determine that it has certain hydrophobicity and oleophobicity. When stains and fingerprints come into contact with the surface of the polysulfonated fluorinated ethylene layer 3, they are not easy to adhere to it due to the surface tension, thereby achieving the effects of anti-fouling and anti-fingerprint. At the same time, the flexibility and strength of its molecular structure also make it have good wear resistance, which enables it to maintain its integrity during the friction process.

[0037] Aluminum oxynitride has good optical performance and thermal stability, can maintain high light transmittance and clarity of the glass cover plate, and prevent the coating layer from being damaged due to temperature changes, the crystal structure and optical properties of aluminum oxynitride determine that it has good optical performance, the atomic arrangement mode enables light to maintain high propagation efficiency when propagating in it, reduces light absorption and scattering, thereby realizing high light transmittance and clarity, in terms of thermal stability, aluminum oxynitride has high chemical bond energy and strong atomic binding force, so that it can maintain a relatively stable structure when the temperature changes, and is not easy to deform or damage;

[0038] In daily use, the cover plate of the electronic device will inevitably come into contact with various objects, and is prone to scratches and wear, and the high-wear-resistant protective layer composed of the zirconium nitride coating layer 4, the polysulfonated polyvinyl fluoride layer 3 and the aluminum oxynitride layer 2 can effectively resist external friction and scratching, thereby significantly prolonging the service life of the cover plate body 1 and reducing the frequency of replacing the device due to damage to the cover plate, thereby saving the cost of the user.

[0039] In today's electronic device use scenarios, clear visual effects are crucial, and the good optical performance of the aluminum oxynitride layer 2 and the zirconium nitride coating layer 4 enables light to smoothly pass through the cover plate body 1, maintaining high light transmittance and clarity, whether watching videos, browsing pictures or reading text, users can enjoy clear and realistic pictures, reducing visual blur or distortion problems caused by poor light transmittance of the cover plate body 1, and improving user satisfaction with the electronic device;

[0040] Further, the thickness of the zirconium nitride coating layer 4 is 5-10 nanometers, the thickness of the polysulfonated polyvinyl fluoride layer 3 is 10-20 nanometers, and the thickness of the aluminum oxynitride layer 2 is 15-25 nanometers.

[0041] Further, the cover plate body 1 is a glass cover plate; glass has the characteristics of high light transmittance and low refractive index, and can enable light to pass through almost unobstructed, thereby ensuring clear display of the screen of the electronic device, and compared with other materials, the glass cover plate can provide more realistic and vivid color performance, enabling users to enjoy high-quality visual experience.

[0043] Further, as shown in Figure 1 , Figure 2 and Figure 4 , the back surface of the cover plate body 1 is provided with a photosensitive color-changing ink layer 5, the cover plate body 1 has a viewing area and a non-viewing area, and the photosensitive color-changing ink layer 5 is located at the non-viewing area.

[0044] Further, the thickness of the photosensitive color-changing ink layer 5 is 4-5 microns, and the photosensitive color-changing ink layer 5 changes color according to the light intensity, adding unique visual effects and interest to the cover plate body 1, and at the same time, the photosensitive color-changing ink layer 5 can also be used as an identification or decoration element to improve the aesthetics and market competitiveness of the application.

[0045] Under different light intensities, the photosensitive color-changing ink layer 5 will exhibit different color changes, and this dynamic visual effect adds unique charm to the electronic device. During use, the user can see the wonderful color change of the cover plate as the ambient light changes, increasing the interest and freshness of use. Among many electronic devices, the cover plate with the photosensitive color-changing function can make the product stand out and attract the attention of consumers. This unique design can become an important selling point of the product, meeting the needs of consumers for personalization and differentiation. Consumers can display their personality and taste through the photosensitive color-changing cover plate, making the electronic device more unique. The photosensitive color-changing ink layer 5 can be printed with patterns, characters, etc. according to design requirements, forming unique identification or decoration elements. These identification or decorations will exhibit different effects under different lighting conditions, increasing the aesthetics and artistic sense of the product.

[0046] The photosensitive color-changing ink contains special photosensitive molecules. These molecules change their molecular structure after absorbing light of different wavelengths and intensities, causing a change in color. When the intensity of the light changes, the state of the photosensitive molecules also changes, causing the ink layer to exhibit different colors.

[0047] Further, the side of the photosensitive color-changing ink layer 5 away from the cover plate body 1 is provided with a protective layer. The protective layer is used for the protection of the photosensitive color-changing ink layer 5.

Nickel oxide has excellent hardness and wear resistance, which can prevent the photosensitive color-changing ink layer 5 from being scratched.

[0052] Further, as Figure 1 As shown, the thickness of the titanium layer 7 is 5-10 nanometers.

[0053] The application forms a protective layer with high hardness, wear resistance and excellent optical performance by sequentially depositing the zirconium nitride plating film layer 4, the polysulfonated polyvinyl fluoride layer 3 and the aluminum oxide-nitride layer 2 on the surface of the cover plate body 1, and at the same time, the photosensitive color-changing ink layer 5 is screen printed on the back frame area of the cover plate body 1, realizing the unique visual effect that the color changes with the light intensity, the bottom layer uses the nickel oxide layer 6 and the titanium layer 7, further enhancing the wear resistance and corrosion resistance, and this multi-layer structure design not only improves the comprehensive performance of the cover plate, but also meets the dual pursuit of users for beauty and durability;
