[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example 1

[0027] This utility model discloses a novel glass-coated cover plate. (Refer to...) Figure 1 and Figure 2 The display includes: a glass substrate 1, which covers the surface of the display device to protect it; an oxide layer 2, which covers the glass substrate 1, including a titanium oxide layer 21, which has high transparency and UV resistance; an ink layer 3, which covers the surface of the oxide layer 2, and is a water-sensitive color-changing ink layer, with a silicon dioxide layer 32 disposed on the surface of the ink layer 3; the ink layer 3 is disposed at the edge of the oxide layer 2, and both the ink layer 3 and the silicon dioxide layer 32 have diamond-shaped hollow areas 31.

[0028] Based on the above structure, the glass substrate 1 serves as the foundation, providing mechanical protection to safeguard the display device from damage. The titanium oxide in the oxide layer 2 may act as a UV shield and provide high light transmittance, protecting the display device from UV damage while maintaining transparency for a clearer view of the displayed content. The ink layer 3 changes color when exposed to water, serving as an indicator of air humidity and as an external decoration for the display screen. Silica may enhance the ink's abrasion resistance, and the diamond-shaped perforations can be used for light transmission or decorative patterns.

[0029] Optionally, a water-sensitive color-changing ink layer 3 is used. When the surface of the display device is wetted, it can produce a color change, and the color depth changes according to the degree of wetness. If the display device is completely dropped into water and left to stand in the water for a period of time, the water-sensitive color-changing ink will turn close to white, thus reminding the user that there is a risk of water damage to the display device and that the display device needs to be placed in the sun to dry. The color of the water-sensitive color-changing ink will gradually darken during the drying process, thus reminding the user that the moisture on the surface of the display device is gradually decreasing.

[0030] In addition, water-sensitive color-changing inks can also change color based on air humidity. When the air humidity is high, the color of the water-sensitive color-changing ink becomes lighter, indicating to the user that the air humidity is high that day.

[0031] Optionally, the water-sensitive color-changing ink uses a microencapsulated cobalt salt complex containing 15 to 20 wt% silica nanoparticles (with a particle size of 20-50 nm), 5 to 8 wt% acrylate prepolymer, 40 to 50 wt% photoinitiator (TPO), and 3 to 5 wt% solvent (a mixture of ethyl acetate and isopropanol).

[0032] Optionally, the border width of ink layer 3 is set to 1.5mm, and the size of the diamond-shaped cutout unit is 0.3×0.3mm. Since ink layer 3 is located on the outermost side of the display device and is susceptible to wear, its wear resistance can be increased by adding silica material to ink layer 3 or by setting a silica layer 32 on the surface of ink layer 3. The area of ​​silica layer 32 is the same as that of ink layer 3. At the locations of the diamond-shaped cutout areas 31 in ink layer 3, the silica layer 32 also has corresponding diamond-shaped cutout areas 31. This effectively protects the ink layer 3 exposed to the external environment.

[0033] Optionally, a silica layer 32 is provided on the surface of the ink layer 3, which to some extent prevents the water-sensitive ink layer 3 from contacting water. Therefore, a diamond-shaped perforation structure is provided on both the silica layer 32 and the ink layer 3. At the diamond-shaped perforation structure, the ink layer 3 comes into contact with the external environment, thus changing color when exposed to water or air humidity. In addition, the diamond-shaped perforation structure is more aesthetically pleasing, increasing the appearance of the display device's outer surface and improving the user experience.

[0034] Reference Figure 3 In this preferred embodiment, the glass substrate 1 includes a visible area 11 and a non-visible area 12; the non-visible area 12 is disposed along the edge of the visible area 11 and is located outside the visible area 11; the ink layer 3 is disposed in the non-visible area 12 and does not enter the visible area 11.

[0035] Based on the above structure, the visible area 11 is the core area of ​​the display device, corresponding to the position of the effective pixel array of the LCD or OLED, and is used to display image content. The non-visible area 12 extends outward from the edge of the visible area 11 by 1.5-2.0mm, forming a ring-shaped area. A metal trace groove (50-80μm deep) is provided below the non-visible area 12. Various traces exist at the corresponding position of the non-visible area 12. The ink layer 3 is applied to the non-visible area 12 to effectively cover the traces corresponding to the non-visible area 12, thereby ensuring the aesthetic appearance of the display device.

[0036] Reference Figure 1 In this preferred embodiment, the oxide layer 2 further includes a molybdenum oxide layer 22, which is disposed between the titanium oxide layer 21 and the glass substrate 1, and has high light transmittance and wear resistance.

[0037] Based on the above structure, molybdenum oxide (MoO) x There are two forms: MoO2 and MoO3. Using MoO3 as the molybdenum oxide layer 22, MoO3 has a high refractive index (approximately 2.3-2.7) and good light transmittance, especially in the visible light region, where its transmittance can reach 92%. Simultaneously, MoO3 has a higher hardness than the glass substrate 1, providing wear resistance and protecting the glass substrate 1.

[0038] Optionally, the titanium oxide layer 21 has antibacterial properties, so the titanium oxide layer 21 is disposed on the outer surface of the molybdenum oxide layer 22 to inhibit bacteria spread from the external environment, effectively ensuring the effect of the titanium oxide layer 21. At the same time, the light transmittance is improved based on the molybdenum oxide layer 22, effectively improving the user experience.

[0039] In this preferred embodiment, the oxide layer 2 further includes a tungsten oxide layer 23, which is disposed on the surface of the titanium oxide layer 21 and located on the side away from the glass substrate 1, and has electrochromic properties.

[0040] Based on the above structure, titanium metal is disposed within the titanium oxide layer 21. The titanium ions within the titanium metal are conductive ions, exhibiting conductive transport properties. To enhance the user experience of the display device, a tungsten oxide layer 23 can be disposed on the surface of the titanium oxide layer 21. Based on the conductivity of the titanium ions in the titanium oxide layer 21, coloring is achieved at the cathode of the tungsten oxide layer 23; that is, the tungsten metal in the tungsten oxide layer 23 will form a color under a negative voltage. When a finger touches the display device, the sensing components inside the device generate a voltage change. This, combined with the conductivity of the titanium ions in the titanium oxide layer 21, causes the tungsten metal in the tungsten oxide layer 23 to color at the cathode, resulting in a color-changing phenomenon on the display device surface. This enhances the visual appeal of the display device and improves the user experience.

[0041] Optionally, the electrochromic principle of the tungsten oxide layer 23 is based on the insertion and extraction of ions or protons in tungsten metal, which causes a color change on the surface of the tungsten oxide layer 23, from transparent to blue.

[0042] In this preferred embodiment, the oxide layer 2 further includes an indium tin oxide layer 24, which is disposed between the tungsten oxide layer 23 and the ink layer 3, and has high light transmittance and high conductivity.

[0043] Based on the above structure, ITO stands for Indium Tin Oxide, a transparent conductive material composed of indium oxide (In₂O₃) and tin oxide (SnO₂). The indium tin oxide layer 24, with its high conductivity, is disposed on the outermost side of the oxide layer 2. When a finger touches the surface of the indium tin oxide layer 24, electrons are generated at the finger contact point and move towards the sensing components within the display device, thereby accurately identifying the finger's touch position and ensuring the normal operation of the touch function.

[0044] Optionally, the indium tin oxide layer 24 has high light transmittance, with a light transmittance of over 92% in the visible light region and an infrared light interception rate of over 80%, effectively avoiding dizziness caused by reflected light when users view the display device, thereby improving the user experience.

[0045] Optionally, the thickness of the indium tin oxide layer 24 is between 50 nanometers and 200 nanometers. The indium tin oxide layer 24 has high light transmittance. When the thickness is higher, the light transmittance decreases. The indium tin oxide layer 24 also has high conductivity. As the thickness increases, the conductivity increases. In order to balance the conductivity and high light transmittance of the indium tin oxide layer 24, the indium tin oxide layer 24 is set to be between 50 nanometers and 200 nanometers.

[0046] In this preferred embodiment, the thickness of the molybdenum oxide layer 22 is between 50 nanometers and 100 nanometers.

[0047] Based on the above structure, the molybdenum oxide layer 22 has high light transmittance. However, the thicker the molybdenum oxide layer 22, the lower the light transmittance. To ensure high light transmittance, the thickness of the molybdenum oxide layer 22 needs to be reduced. Simultaneously, the molybdenum oxide layer 22 has high wear resistance. The thinner the molybdenum oxide layer 22, the worse the wear resistance. Therefore, the thickness of the molybdenum oxide layer 22 needs to be increased. By balancing high light transmittance and wear resistance, the molybdenum oxide layer 22 is set between 50 nanometers and 100 nanometers. This effectively ensures high light transmittance while improving wear resistance, effectively protecting the internal glass substrate 1 from scratches.

[0048] In this preferred embodiment, the thickness of the titanium oxide layer 21 is between 100 nanometers and 200 nanometers.

[0049] Based on the above structure, titanium metal ions are placed in the titanium oxide layer 21 to achieve the conductivity of the titanium oxide layer 21. In order to ensure the movement of titanium metal ions and achieve the high transmittance of the titanium oxide layer 21, the titanium oxide layer 21 needs to be set between 100 nanometers and 200 nanometers, thereby improving the high transmittance of the titanium oxide layer 21 and ensuring the conductivity effect of the movement of titanium metal ions in the titanium oxide layer 21.

[0050] In this preferred embodiment, the thickness of the tungsten oxide layer 23 is between 50 nanometers and 150 nanometers; the thickness of the ink layer 3 is between 6 micrometers and 8 micrometers.

[0051] Based on the above structure, ink layer 3 covers the wiring inside the display device. Simultaneously, ink layer 3 is disposed on the outer surface of the display device, preventing the wiring from being exposed due to wear. Increasing the thickness of ink layer 3 allows for multiple screen printing processes, forming multiple layers, thus preventing easy wear. Furthermore, it is necessary to ensure a small height difference between ink layer 3 and oxide layer 2 to avoid an excessively thick ink layer 3 that would result in an unsightly display surface. Therefore, the overall thickness of ink layer 3 is set to 6 to 8 micrometers, effectively achieving the effect of preventing wear and maintaining an aesthetically pleasing outer surface.

[0052] Optionally, the molybdenum oxide, titanium oxide, and tungsten trioxide layers 23 in the multi-layer coating structure all possess excellent wear resistance, corrosion resistance, and oxidation resistance, effectively extending the service life of the cover plate. Simultaneously, by precisely controlling the thickness and refractive index of each layer, the optical performance of the cover plate can be optimized, improving light transmittance and reducing reflection and scattering. The titanium oxide layer 21 further enhances UV resistance and self-cleaning capabilities.

[0053] The tungsten trioxide layer 23 endows the cover plate with a special electrochromic function, enabling it to display different colors according to changes in the applied electric field, thus increasing the intelligence and interactivity of the display device. At the same time, the water-sensitive ink layer 3 also provides waterproof marking and environmentally sensitive display functions.

[0054] In addition, the water-sensitive color-changing ink layer 3 can be set with a diamond-shaped hollow area 31, which, combined with the electrochromic properties of the tungsten trioxide layer 23, gives the cover a unique visual effect and appeal.

[0055] Example 2

[0056] The present invention provides a display device, including a novel glass-coated cover plate.

[0057] The implementation principle of the novel glass coated cover plate and display device of this utility model is as follows:

[0058] A multifunctional layered structure was constructed on the front side of the glass substrate 1.

[0059] A glass substrate 1 with high light transmittance, high mechanical strength, and good chemical stability serves as the support for the entire coating structure. Subsequently, a molybdenum oxide layer 22, a titanium oxide layer 21, and a tungsten trioxide layer 23 are deposited sequentially.

[0060] The molybdenum oxide layer 22 acts as a barrier layer, effectively protecting the underlying glass substrate 1 from the influence of the external environment. The titanium oxide layer 21, with its high refractive index and low absorptivity, enhances the light transmittance and UV resistance of the cover plate and imparts a self-cleaning function. The tungsten trioxide layer 23 is key to achieving electrochromic properties; through the application of an external electric field, the color of the cover plate can be reversibly changed, adding a smart element to the product. Finally, a water-sensitive color-changing ink layer 3 is screen-printed on the top edge area of ​​the front side of the glass substrate 1. When exposed to water or moisture, the ink color changes, providing not only a decorative effect but also an indication or anti-counterfeiting function.

[0061] This multi-layer coating combined with special ink design not only enhances the optical performance and durability of the cover plate, but also endows it with unique visual interaction and environmental perception capabilities.
