Especially in high-end markets such as smartphones, tablets, and automotive displays, users not only expect products to have superior durability but also seek unique aesthetic experiences and interactive functions.

[0024] To address the problems existing in the prior art, this application / utility invention provides a display device that enhances coating adhesion. Figure 1 A top view of a glass cover plate provided in an embodiment of the present utility model; Figure 2 This is a side view of a coated cover plate provided according to an embodiment of the present invention. Figure 1-2 As shown, the system includes a coated cover plate, comprising: a glass cover plate 101; a tin-plated layer 102 disposed on the front side of the glass cover plate 101, the tin-plated layer 102 having certain corrosion resistance and ductility, used to enhance the adhesion of the glass cover plate 101, the tin-plated layer 102 serving as a transition layer, enhancing the adhesion of subsequent coatings, and possessing certain corrosion resistance and ductility, providing additional protection for the overall coating layer; and a titanium dioxide layer 103. On the tin-plated layer 102, the titanium dioxide layer 103 not only has excellent photocatalytic properties but also ultraviolet absorption capabilities, which enhances the UV resistance of the glass cover 101, reduces UV damage to the glass interior, and also provides a certain degree of heat insulation. The titanium carbide layer 104, disposed on the titanium dioxide layer 103, has high hardness and wear resistance, which enhances the scratch and wear resistance of the front surface of the glass cover 101, protecting the surface of the glass cover. It also possesses excellent corrosion resistance and good thermal stability; a thermochromic ink layer 105 is disposed around the back of the glass cover plate 101; a titanium nitride layer 106 is disposed on the thermochromic ink layer 105, which enhances the scratch resistance of the thermochromic ink layer 105; the titanium nitride layer 106 serves as a protective layer, ensuring that the thermochromic ink layer 105 maintains stable performance under complex environments and extends its service life; an electromagnetic layer. 108. An electromagnetic layer 108 is disposed between the titanium nitride layer 106 and the display module 107, and the display module 107 is connected to the coated cover plate through the electromagnetic layer 108; the display module 107 is disposed on the coated cover plate; the frame 109 includes an enclosure portion 1091 and a fixing portion 1092. The enclosure portion 1092 is disposed around the coated cover plate, and the fixing portion 1092 is disposed on the upper surface of the coated cover plate, for fixing the glass cover plate 101 and the display module 107.

[0025] Preferably, a tin plating layer 102, a titanium dioxide layer 103, and a titanium carbide layer 104 are sequentially plated on the front side of the glass cover 101. Utilizing the properties of these three materials, the tin plating layer, titanium dioxide layer, and titanium carbide layer together provide excellent wear resistance, effectively enhance the adhesion of the glass cover, protect the surface of the glass cover from scratches, and provide UV resistance, maintaining good performance even in harsh environments. The titanium nitride layer 106 serves as an inner protective layer, effectively preventing the thermochromic ink layer 105 from being scratched, while also providing additional chemical and thermal stability, jointly extending the service life of the glass cover 101.

[0026] By first setting a tin-plated film layer 102 on the glass cover plate 101, the adhesion of subsequent coatings can be enhanced, while also possessing certain corrosion resistance and ductility. The display module 107 is connected to the film-plated cover plate through the electromagnetic layer 108, which facilitates connection and simplifies the process. By setting a frame 109 around the glass cover plate 101, the glass cover plate 101 and the display module 107 are enclosed within the frame 109, which helps to improve production efficiency.

[0027] In some preferred embodiments, the electromagnetic layer 108 includes: a first electromagnetic layer 1081 disposed on the titanium nitride layer 106; and a second electromagnetic layer 1082 disposed between the first electromagnetic layer 1081 and the display module 107 for connecting the display module 107 to the coating cover plate.

[0028] In some preferred embodiments, the first electromagnetic layer 1081 and the second electromagnetic layer 1082 are magnetically repelled. Pressing the glass cover 101 activates the second electromagnetic layer 1082, thus unlocking the corresponding function. Releasing the pressure causes the layer to spring back to its original position due to the repulsion of like poles. Pressing the glass cover 101 is used to adjust the backlight brightness. In the prior art, a spring is used between the coated cover and the display module to adjust the backlight brightness. This embodiment uses the magnetic repulsion between the first electromagnetic layer 1081 and the second electromagnetic layer 1082 to adjust the backlight brightness, which is more convenient.

[0029] In some preferred embodiments, the thickness of the tin plating layer 102 is 10nm-15nm.

[0030] Preferably, tin has a low resistivity (approximately 1). Tin plating can replace precious metals such as silver as a conductive coating, reducing costs while meeting the performance requirements of low-voltage systems. The tin plating layer 102 is chemically stable at room temperature, and the dense oxide film (such as SnO2) formed on its surface effectively isolates air, moisture, and organic acids, delaying substrate corrosion. It is almost non-corrosive in dry environments. Therefore, a 10nm-15nm tin plating layer 102 is deposited on the glass cover plate 101. As a transition layer, the tin plating layer 102 enhances the adhesion of subsequent coatings and possesses certain corrosion resistance and ductility, providing additional protection for the overall coating layer.

[0031] In some preferred embodiments, the thickness of the titanium dioxide layer 103 is 20 nm to 30 nm.

[0032] Preferably, the titanium dioxide is a white solid or powder, odorless and tasteless, and has a high refractive index. A titanium dioxide layer 103 with a thickness of 20nm-30nm is deposited on the tin-plated film layer 102, which not only has excellent photocatalytic performance but also ultraviolet absorption capabilities, reducing ultraviolet damage to the interior of the glass. Furthermore, it also provides a certain degree of heat insulation.

[0033] In some preferred embodiments, the thickness of the titanium carbide layer 104 is 10 nm to 20 nm.

[0034] Preferably, titanium carbide is a face-centered cubic solid with a metallic luster, which is iron-gray or gray and has extremely high hardness and wear resistance. A 10nm-20nm thick titanium carbide layer 104 is then deposited on the titanium dioxide layer 103, which can effectively prevent scratches and wear on the glass cover 101 during daily use, protect the glass surface, and also has excellent corrosion resistance and good thermal stability.

[0035] In some preferred embodiments, the thickness of the thermochromic ink layer 105 is between 8 μm and 12 μm.

[0036] 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.

[0037] In some preferred embodiments, the thickness of the titanium nitride layer 106 is 10 nm to 20 nm.

[0038] Preferably, the titanium nitride layer 106 serves as a protective layer, effectively preventing scratches on the ink layer. A 10-20 nm thick titanium nitride layer 106 is deposited on the thermochromic ink layer 105 to effectively prevent scratches or damage to the thermochromic ink during manufacturing, transportation, and use, maintaining its excellent color-changing performance and appearance. Simultaneously, the high hardness and wear resistance of titanium nitride provide additional protection for the overall coating layer.

[0039] This invention achieves a comprehensive improvement in the performance of the glass cover 101 by combining materials with different properties. First, a tin plating layer 102, a titanium dioxide layer 103, and a titanium carbide layer 104 are sequentially deposited on the front side of the glass cover 101. The outermost layer on the front side of the glass cover 101 is the titanium carbide layer 104, which significantly improves the scratch resistance of the glass cover 101 surface with its high hardness, high strength, and wear resistance. Then comes the titanium dioxide layer 103, which further enhances the wear resistance and works synergistically with the titanium carbide layer 104. The tin plating layer 102 serves as a transition layer, which can enhance the adhesion of subsequent coatings and has certain corrosion resistance and ductility, providing additional protection for the overall coating layer.

[0040] On the back edge of the glass cover 101, thermochromic ink is used for screen printing, giving the product a unique sense of fun and interactivity. The screen printing process is flexible and versatile, allowing for the customization of diverse patterns and enhancing the product's aesthetics. To prevent damage to the thermochromic ink layer 105, a titanium nitride layer 106 is deposited beneath it. The titanium nitride layer 106 effectively prevents the thermochromic ink from being scratched or damaged during manufacturing, transportation, and use, maintaining its excellent color-changing performance and appearance. It also effectively prevents scratches on the thermochromic ink layer 105, ensuring the long-term stability and durability of the entire coating structure. This multi-layer coating design, through the synergistic effect between layers, improves the glass cover's performance in terms of physical protection, photocatalysis, UV protection, and temperature indication, meeting the market's comprehensive demand for high-quality, multi-functional electronic product cover materials.

[0041] 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.
