Figure 1-5 As shown, the light-replenishing coated cover plate includes a glass cover plate 101; a nickel borosilicate alloy layer 102, a tin bronze alloy layer 103, and a silicon dioxide layer 104 are sequentially disposed on the front side of the glass cover plate 101 from the surface outwards. The nickel borosilicate alloy layer 102 is used to enhance the corrosion resistance and hardness of the front side of the glass cover plate 101; the tin bronze alloy layer 102 is used to enhance the scratch resistance of the front side of the glass cover plate 101; the silicon dioxide layer 104 is used to enhance the scratch resistance and wear resistance of the front side of the glass cover plate 101; a thermochromic ink layer 105, an aluminum bronze alloy layer 106, and a niobium pentoxide layer 107 are sequentially disposed on the back side of the glass cover plate 101 from the surface outwards.

The first acrylic sheet 1081 is disposed on one side of the glass cover 101, and the second acrylic sheet 1082 is disposed on the other side of the glass cover 101. Both the first acrylic sheet 1081 and the second acrylic sheet 1082 are matched with the glass cover 101. A chrome-plated mirror layer 109 is disposed on the first acrylic sheet 1081 to improve the reflectivity of the first acrylic sheet 1081. Multiple LED light strips 1010 are equally spaced on the second acrylic sheet 1082 for supplementary lighting. A power supply battery 1011 is disposed on the second acrylic sheet 1082 and is electrically connected to the multiple LED light strips 1010.

[0036] Preferably, a first acrylic plate 1081 and a second acrylic plate 1082 are provided on both sides of the glass cover 101. Both the first acrylic plate 1081 and the second acrylic plate 1082 can be pulled out from the glass cover 101. When supplementary lighting is needed, the second acrylic plate 1082 is pulled out, and the power supply battery 1011 provides power to the LED light strip, thereby providing supplementary lighting to the display device. A layer of chromium is plated on the first acrylic plate 1081 to form a chromium-plated mirror layer 109, which has reflective properties and is used to reflect the light emitted by the LED light strip to the display device, thereby improving the brightness of the display device.

[0037] Preferably, by depositing a nickel borosilicate alloy layer 102, a tin bronze alloy layer 103, and a silicon dioxide layer 104 on the front side of the glass cover 101, the high hardness and high wear resistance of these three materials are utilized to effectively protect the surface of the glass cover 101 from scratches and maintain good performance even in harsh environments. A thermochromic ink layer 105 is screen-printed on the frame area on the back side of the glass cover 101. To prevent damage to the thermochromic ink layer 105, an aluminum bronze alloy layer 106 and a niobium pentoxide layer 107 are provided below the thermochromic ink area 105 as an inner protective layer, which effectively prevents the thermochromic ink layer 105 from being scratched, while providing additional chemical and thermal stability, thus extending the service life of the coated cover.

[0038] In some preferred embodiments, the device further includes: a first receiving groove 1012, which is formed on one side of the glass cover plate 101 and matches the first acrylic plate 1081; and a second receiving groove 1013, which is formed on the other side of the glass cover plate 101 and matches the second acrylic plate 1082.

[0039] Preferably, both the first acrylic plate 1081 and the second acrylic plate 1082 are U-shaped structures. The U-shaped first acrylic plate 1081 matches the first receiving groove 1012, and the first acrylic plate 1081 can be pulled out along the first receiving groove 1012. Similarly, the U-shaped second acrylic plate 1082 matches the second receiving groove 1013, and the second acrylic plate 1082 can be pulled out along the second receiving groove 1013, thereby achieving supplementary lighting for the display device to improve the brightness of the display device.

[0040] In some preferred embodiments, the thickness of the silicon dioxide layer 104 is between 50 nanometers and 100 nanometers.

[0041] Preferably, silicon dioxide is a thin film of compound (SiO2) composed of silicon and oxygen elements, which has excellent insulation, chemical stability, thermal stability and optical properties. Depositing a layer of silicon dioxide 103 on the outermost layer of the glass cover 101 can effectively protect the surface of the glass cover 101 from the corrosion of the external environment, so that the glass cover 101 has excellent wear resistance, scratch resistance and chemical stability, while providing a smooth surface texture.

[0042] In some preferred embodiments, the thickness of the tin bronze alloy layer 103 is between 20 nanometers and 30 nanometers.

[0043] Preferably, the tin bronze alloy is bronze with tin as the main alloying element, and the tin content is usually between 3% and 14%. In addition to tin, elements such as phosphorus, zinc, and lead are often added to improve performance. Phosphorus acts as a deoxidizer, improving fluidity and wear resistance, but excessive amounts can lead to hot brittleness. Zinc improves casting performance, narrows the crystallization temperature range, and reduces inverse segregation. Lead reduces the coefficient of friction, improves machinability and wear resistance, but slightly reduces mechanical properties. By plating a layer of tin bronze alloy on the glass cover plate 101, the tin bronze alloy, with its good corrosion resistance and certain hardness, can further enhance the protective performance of the glass cover plate 101, and work synergistically with the silicon dioxide layer 103 to improve overall durability.

[0044] In some preferred embodiments, the thickness of the nickel boron silicon alloy layer 102 is between 20 nanometers and 30 nanometers.

[0045] Preferably, the nickel-boron-silicon alloy is a self-fluxing alloy formed by adding boron and silicon elements to nickel as the base. The addition of boron and silicon significantly strengthens the nickel-based solid solution, improves the hardness of the alloy, and has good corrosion resistance to media such as atmosphere, seawater, steam, and dilute sulfuric acid and hydrochloric acid. The nickel-boron-silicon alloy maintains red hardness in the temperature range of 500-600℃. A layer of nickel-boron-silicon alloy is plated on the front side of the glass cover 101. With its unique physical and chemical properties, it provides additional hardness, wear resistance and corrosion resistance, further protects the surface of the glass cover 101 and ensures the long-term stability of the coating layer.

[0046] In some preferred embodiments, the thickness of the thermochromic ink layer 105 is between 8 micrometers and 12 micrometers.

[0047] Preferably, thermochromic inks can change color according to temperature changes, increasing the fun and interactivity of products. Through screen printing, a variety of patterns and colors can be designed to enhance the aesthetics of products.

[0048] In some preferred embodiments, the thickness of the aluminum bronze alloy layer 106 is between 30 nanometers and 40 nanometers.

[0049] Preferably, aluminum bronze alloy is a copper-based alloy with aluminum as the main alloying element, and usually also contains elements such as iron, manganese, and nickel. It has excellent properties such as high strength, wear resistance, corrosion resistance, and high temperature resistance. The aluminum content of aluminum bronze generally does not exceed 11.5%, and elements such as iron, manganese, and nickel may be added to improve its performance. It has high strength, hardness, and wear resistance. In the atmosphere, fresh water, and seawater, aluminum bronze exhibits good corrosion resistance. Aluminum bronze can maintain stable mechanical properties below 400℃. A layer of aluminum bronze alloy 106 is plated on the surface of the thermochromic ink layer 105. With its high hardness and good corrosion resistance, it effectively prevents the thermochromic ink layer from being scratched, providing a solid protective barrier for the thermochromic ink.

[0050] In some preferred embodiments, the thickness of the niobium pentoxide layer 107 is between 15 nanometers and 25 nanometers.

[0051] Preferably, niobium pentoxide is a white powder with a density of approximately 4.47-4.6 g / cm³. 3 It has a melting point of 1485-1520℃, is insoluble in water, sparingly soluble in most acids (except sulfuric acid and hydrofluoric acid), but soluble in molten potassium bisulfate or alkali metal carbonates and hydroxides. It exhibits significant acidity; when fused with alkali at high temperatures, it can form niobium hydroxide, which, upon calcination, yields niobium pentoxide. Niobium pentoxide possesses extremely high hardness and chemical stability, further enhancing the overall wear resistance and corrosion resistance, providing additional protection for the thermochromic ink layer 105 and the aluminum bronze alloy layer 106, ensuring the long-term stability of the entire coating structure.

[0052] In some preferred embodiments, the thickness of the chrome-plated mirror layer 109 is between 200 nanometers and 300 nanometers.

[0053] Preferably, a layer of metallic chromium film with high gloss, high hardness, wear resistance, and corrosion resistance is formed on the surface of the first acrylic sheet 1081 through an electroplating process. Chromium has a reflectivity of approximately 65% ​​in the visible light range, which is between that of silver (88%) and nickel (55%). Furthermore, because chromium does not discolor, it can maintain its reflectivity for a long time during use. When the first acrylic sheet 1081 is pulled out from the glass cover 101, the chromium plating on its surface gives it reflectivity.

[0054] Secondly, this utility model provides a display device, which includes the aforementioned coated cover plate.

[0055] This invention achieves a comprehensive improvement in the performance of the glass cover 101 by combining materials with different properties. First, a nickel-boron-silicon alloy layer 102 is sequentially plated on the front side of the glass cover 101. Utilizing its excellent wear resistance and chemical stability, it effectively resists corrosion from the external environment. Subsequently, a tin bronze alloy layer 103 and a silicon dioxide layer 104 are superimposed to further enhance the cover's hardness, wear resistance, and corrosion resistance, forming a robust protective barrier. The glass cover 101 serves as the base, providing necessary transparency and structural support. On the back edge area of ​​the cover 101, a thermochromic ink screen printing layer 105 is introduced, which not only enhances the product's aesthetics and appeal but also allows for personalized customization through flexible screen printing processes. Finally, the inner protective layers of an aluminum bronze alloy layer 106 and a niobium pentoxide layer 107 effectively prevent scratches on the thermochromic ink layer 105 and enhance the overall chemical and thermal stability. This multi-layer coating structure design enables the glass cover 101 to maintain high transparency while possessing excellent wear resistance, corrosion resistance, and high temperature resistance, significantly improving the overall performance and service life of the product.

[0056] Then, when the glass cover 101 needs supplemental lighting, the second acrylic plate 1082 is pulled out from one side of the glass cover 101. Since the second acrylic plate 1082 is provided with an LED light strip 1010 and a power supply battery 1011, the LED light strip provides brightness. The first acrylic plate 1081 is pulled out from the other side of the glass cover 101, and the light is reflected to the display device through the chrome-plated mirror layer 109 on the first acrylic plate 1081 to improve the brightness of the display device.

[0057] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of the present invention.
