[0030] 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.

[0031] 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.

[0032] 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.

[0033] Example 1

[0034] Please refer to Figure 1 A photosensitive color-changing coated cover is provided, comprising a substrate 1 having a front and a back. The substrate 1 is a transparent glass plate or a transparent acrylic plate. An anti-corrosion coating is provided on the front of the substrate 1. A photosensitive color-changing ink layer 2 and a protective layer 3 are provided on one edge of the substrate 1. The protective layer 3 covers the photosensitive color-changing ink layer 2. The photosensitive color-changing ink layer 2 can change color under different light intensities. The thickness of the photosensitive color-changing ink layer 2 is 6-8 micrometers. The photosensitive color-changing ink is a special functional ink whose color changes with changes in light conditions. Dynamic color effects are achieved mainly by adding materials with photosensitive color-changing properties, such as photochromic dyes or pigments. The photosensitive color-changing ink layer 2 gives the cover the unique function of changing color with changes in light. When used as an indicator, it can serve as an indicator of light intensity or specific light.

[0035] The anti-corrosion coating consists of three layers: a copper-nickel alloy coating layer 4, a nickel coating layer 5, and a nickel fluoride coating layer 6. The copper-nickel alloy coating layer 4 is deposited on the front side of the substrate 1, the nickel coating layer 5 is deposited on the surface of the copper-nickel alloy coating layer 4, and the nickel fluoride coating layer 6 is deposited on the surface of the nickel coating layer 5. The thickness of the copper-nickel alloy coating layer 4 is 20-50 nanometers, the thickness of the nickel coating layer 5 is 200-250 nanometers, and the thickness of the nickel fluoride coating layer 6 is 50-100 nanometers. The copper-nickel alloy coating layer 4, as the bottom layer, provides excellent corrosion resistance and good mechanical strength, while also possessing a certain degree of conductivity. Its excellent corrosion resistance and mechanical strength provide a solid foundation for the entire coating layer. The nickel coating layer 5, as the main coating layer, not only enhances conductivity but also further improves corrosion resistance and mechanical strength. The nickel fluoride coating layer 6, covering the nickel coating layer 5, significantly improves the surface hardness and wear resistance of the cover plate, effectively resisting the erosion of the external environment. The copper-nickel alloy coating layer 4 and the nickel coating layer 5 together provide the cover plate with excellent corrosion resistance and mechanical strength, enhance the product's durability, and extend the cover plate's service life. The nickel coating layer 5 provides good conductivity, making it suitable for electronic and optical applications that require conductivity, such as products that require electromagnetic shielding and antistatic properties.

[0036] The protective layer 3 is a polyurethane resin layer with a thickness of 16-18 micrometers. As a protective layer beneath the photosensitive color-changing ink layer 2, the polyurethane resin layer 3 effectively prevents the photosensitive color-changing ink layer 2 from being scratched or worn, ensuring the long-lasting aesthetics and functional integrity of the photosensitive color-changing ink layer 2, and extending the product's service life and appearance. At the same time, the flexibility of the polyurethane resin also helps to mitigate the impact of external impacts on the photosensitive color-changing ink layer 2 and the cover plate.

[0037] Example 2

[0038] The photosensitive color-changing coated cover plate provided in Example 1 has been further optimized, specifically, as follows: Figure 2-5 As shown, substrate 1 includes a visible area 101 and a non-visible area 102 surrounding the visible area 101. A photosensitive color-changing ink layer 2 is disposed in the non-visible area 102, which is located at the edge of substrate 1, forming a rectangular frame structure. The width of the photosensitive color-changing ink layer 2 is not greater than the width of the non-visible area 102. The photosensitive color-changing ink layer 2 is formed by screen printing with photosensitive color-changing ink and is located on the reverse side of substrate 1. A cutout area 7 is provided on the photosensitive color-changing ink layer 2, and a thermosensitive color-changing ink layer 8 is disposed at the cutout area 7. The thermosensitive color-changing ink layer 8 can change color at different temperatures. Thermosensitive ink is an ink with a special color-changing function; it can change color according to temperature changes. When the temperature rises or falls to a certain level, the color of the ink will change significantly, and this color-changing effect is reversible. At room temperature, the thermochromic ink is transparent. As the temperature rises, the color of the thermochromic ink gradually deepens. Users can judge the temperature of the substrate 1 based on the color, thereby determining the operating temperature of the display device and the display product using the substrate 1, allowing users to use electronic products reasonably and healthily. The use of both photochromic ink layer 2 and thermochromic ink layer 8 enables the product to produce different visual effects under different temperatures and light intensities, further enhancing the product's visual appeal and providing dual protection to ensure the product is used in a suitable environment. The thermochromic ink layer 8 is located on either the front or back of the substrate 1. In this example, the thermochromic ink layer 8 is located on the back of the substrate 1 and its thickness is the same as that of the photochromic ink layer 2.

[0039] Example 3

[0040] The photosensitive color-changing coated cover plate provided in Example 2 has been further optimized, specifically, as follows: Figure 6 As shown, the photosensitive color-changing ink layer 2 is located on the reverse side of the substrate 1, and the side of the photosensitive color-changing ink layer 2 facing away from the substrate 1 is screen-printed with a thermosensitive color-changing ink layer 8. The side of the thermosensitive color-changing ink layer 8 facing away from the photosensitive color-changing ink layer 2 is provided with a protective layer 3. There is no cutout area 7 on the photosensitive color-changing ink layer 2. The thermosensitive color-changing ink layer 8 directly covers the photosensitive color-changing ink layer 2. By using the photosensitive color-changing ink and the thermosensitive color-changing ink to generate different color layers under different light intensities and temperatures, a new color is formed, which further enhances the edge color change of the cover plate and improves the visual effect of the product.

[0041] The working principle of the photosensitive color-changing coated cover provided by this utility model is as follows: A multifunctional protective and decorative layer is constructed on the substrate 1 through a layer-by-layer coating technology. First, a copper-nickel alloy coating layer 4 serves as the bottom layer, providing a solid foundation for the entire coating layer with its excellent corrosion resistance and mechanical strength. Subsequently, the addition of a nickel coating layer 5 not only enhances conductivity but also further improves corrosion resistance and mechanical strength. Following this, the covering of a nickel fluoride coating layer 6 significantly improves surface hardness and wear resistance, effectively resisting the erosion of the external environment. The photosensitive color-changing ink screen printing layer on the reverse side of the substrate 1 displays different colors according to changes in light, giving the product a unique visual appeal. Finally, a polyurethane resin layer serves as the protective layer 3, ensuring the long-lasting aesthetics and functional integrity of the ink layer. Its excellent wear resistance, chemical resistance, and flexibility also provide additional protection for the overall structure. This layered structural design not only improves the overall performance of the glass cover but also meets the modern electronic product's pursuit of both aesthetics and functionality.
