Description
Technical Field
[0001] This utility model relates to the technical field of glass cover plates, and in particular to a coated cover plate with a color-changing border and a display device. Background Technology
[0002] With the rapid development of science and technology, the widespread application of electronic devices and display technologies has placed higher demands on the performance of cover plate materials. Coated cover plates are set on the surface of display devices to protect them.
[0003] In related technologies, while traditional glass covers offer basic protective functions, their wear resistance, corrosion resistance, optical performance, and aesthetics still need improvement. In existing technologies, display devices are powered by a power source, and the glass covers covering these devices lack insulation, allowing a small current to pass through. While this poses no physical harm, it does affect the user's tactile experience of the display device. Utility Model Content
[0004] In order to solve the problems existing in the prior art, the present invention provides a coated cover plate with a color-changing border and a display device.
[0005] On one hand, the present invention provides a coated cover plate with a color-changing border, which adopts the following technical solution, including: a glass cover plate, an ink layer, and a strontium titanate layer; the strontium titanate layer is disposed on the surface of the glass cover plate, and the strontium titanate layer has insulation and optical transparency; the ink layer is disposed on the surface of the strontium titanate layer and is disposed on the side away from the glass cover plate, covering the glass cover plate and the strontium titanate layer.
[0006] By adopting the above technical solution, the glass cover provides the most basic protection for the display device. A strontium titanate layer is applied to the glass cover. Due to its high dielectric constant and good insulation properties, the strontium titanate layer effectively blocks minute charges from escaping from the display device. Display devices may experience minor static electricity, generating a small current upon touch. The strontium titanate layer effectively reduces these minute currents and improves the user experience.
[0007] Optionally, the ink layer may be made of water-sensitive ink.
[0008] Optionally, the thickness of the ink layer is 6 micrometers to 8 micrometers.
[0009] Optionally, the thickness of the strontium titanate layer is 50 nanometers to 100 nanometers.
[0010] Optionally, the glass cover includes a visible area and a non-visible area, the non-visible area being disposed outside the edge of the visible area along the edge of the visible area; the ink layer covering the corresponding non-visible area of the glass cover.
[0011] Optionally, it may also include an intermediate layer disposed between the strontium titanate layer and the ink layer, the intermediate layer having abrasion resistance and chemical stability.
[0012] Optionally, the intermediate layer includes: an aluminum nitride layer, which is closely bonded to the strontium titanate layer and has wear resistance and corrosion resistance; and a boron trioxide layer, which is disposed between the aluminum nitride layer and the ink layer and has chemical stability.
[0013] Optionally, the thickness of the aluminum nitride layer is 20 nanometers to 50 nanometers.
[0014] Optionally, the thickness of the boron trioxide layer is 20 nanometers to 50 nanometers.
[0015] On the other hand, the present invention provides a display device including a coated cover plate with a color-changing border.
[0016] Any of the above-described technical solutions of this utility model has at least some of the following beneficial effects:
[0017] 1. The glass cover provides the most basic protection for the display device. A strontium titanate layer is placed on the glass cover. Due to the high dielectric constant and good insulation properties of the strontium titanate layer, it can effectively block the tiny charges that may leak from the display device.
[0018] 2. Water-sensitive inks will change color when exposed to changes in air humidity or water content. Users can intuitively perceive changes in the water content of the display device by observing the color change of the water-sensitive ink, thereby increasing the interest and practicality of the coating cover.
[0019] 3. The ink layer thickness is set to 6 to 8 micrometers, which effectively balances the covering effect and material cost, and also improves the user experience;
[0020] 4. An intermediate layer is disposed between the strontium titanate layer and the ink layer, i.e., on the side of the glass cover that contacts the display device, to prevent damage to the strontium titanate layer when the glass cover is installed on the display device, effectively protecting the integrity of the coated cover. The strontium titanate layer is relatively thin and does not possess wear-resistant properties, thus requiring protection to prevent damage to the strontium titanate layer.

[0027] 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.
[0028] 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.
[0029] Example 1
[0030] This utility model discloses a coated cover plate with a color-changing border. (Refer to...) Figure 1 It includes: a glass cover plate 1, an ink layer 4, and a strontium titanate layer 2; the strontium titanate layer 2 is disposed on the surface of the glass cover plate 1, and the strontium titanate layer 2 has insulation and optical transparency; the ink layer 4 is disposed on the surface of the strontium titanate layer 2 and is disposed on the side away from the glass cover plate 1, covering the glass cover plate 1 and the strontium titanate layer 2.
[0031] By adopting the above technical solution, the glass cover 1 provides basic protection for the display device. A strontium titanate layer 2 (SrTiO3) is applied to the glass cover 1. Due to its high dielectric constant and good insulation properties, the strontium titanate layer 2 effectively blocks the small charges that may leak from the display device. While the display device itself has a leakage detection circuit, preventing large amounts of electrical energy from leaking out, it may still experience minor static electricity, generating a small current upon touch. The strontium titanate layer 2 (SrTiO3) effectively reduces these small currents and improves the user experience.
[0032] Specifically, strontium titanate layer 2 (SrTiO3) possesses a high dielectric constant and excellent insulation properties. A high dielectric constant refers to the material's relatively high ability to store electrostatic energy in an electric field. A higher dielectric constant indicates a higher degree of polarization of the strontium titanate layer 2 in an electric field, and a stronger ability to store charge. SrTiO3 is used for anti-static protection of coated cover plates, effectively reducing interference to display devices. Simultaneously, strontium titanate layer 2 can also form electromagnetic shielding, effectively blocking external electromagnetic wave interference and preventing electromagnetic wave leakage. Excellent insulation properties refer to the material's ability to resist the passage of current. In display devices, the excellent insulation properties of strontium titanate layer 2 can isolate parts with different potentials, preventing minute electrostatic currents from affecting the tactile feel.
[0033] In this preferred embodiment, the material of ink layer 4 is an ink that changes color when exposed to water.
[0034] By adopting the above technical solution, the water-sensitive ink will change color when the air humidity or water content changes. Users can intuitively feel the change in the water content of the display device based on the color change of the water-sensitive ink, thereby increasing the fun and practicality of the coating cover.
[0035] When the water content changes, the color of the water-sensitive ink in ink layer 4 changes accordingly, resulting in variations in color and brightness of the pattern. As the user uses the display device, the water content parameter changes over time and in different environments, causing the color or brightness of ink layer 4 to change as well. Therefore, without replacing the coating cover, users can experience a variety of different appearance colors, effectively enhancing the user experience.
[0036] It should be noted that the color of the water-sensitive ink changes with the water content, which is a component known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
[0037] Specifically, water-sensitive inks contain water-sensitive pigments that display different colors depending on the water content. For example, this is useful if a display device is accidentally dropped into water, or if the device is touched with wet hands. The water-sensitive ink can display different colors depending on the water content, increasing the user's enjoyment.
[0038] In addition, based on the setting of water-sensitive color-changing ink, it can also be used to test the sealing performance of display devices. Display devices need to seal internal electrical components. When the display device is placed in water, the presence of unqualified sealing can be observed based on whether the ink layer 4 changes color. The sealing effect of the display device can also be judged based on the time or degree of color change of the ink layer 4.
[0039] In this preferred embodiment, the thickness of ink layer 4 is 6 micrometers to 8 micrometers.
[0040] By adopting the above technical solution, the ink layer 4 is placed on the surface of the strontium titanate layer 2 by screen printing, which can effectively cover the ribbon cables in the display device. The ink layer 4 has a good covering effect. If the thickness of the ink layer 4 is too low, the covering effect is poor, that is, it cannot completely cover the ribbon cables. If the thickness of the ink layer 4 is too high, there will be more material waste, increased cost, and a thicker coating cover plate, resulting in a poor user experience. Therefore, the thickness of the ink layer 4 is set to 6 micrometers to 8 micrometers, which effectively balances the covering effect and material cost, and also improves the user experience.
[0041] It should be noted that display devices contain various display components, including but not limited to diodes, photosensitive circuits, and / or LED display elements. All of these components are connected to the terminal control unit via tiny wires. The terminal control unit then transmits the content to be displayed through these tiny wires, thus enabling the display of the content. These tiny wires are called the ribbon cables of the display device. These ribbon cables are numerous and complex, often resulting in a messy appearance. The ribbon cables are located on the outer ring of the display device and are covered with ink to effectively prevent them from being displayed to the user, while also improving the aesthetics of the display device.
[0042] In this preferred embodiment, the thickness of the strontium titanate layer 2 is 50 nanometers to 100 nanometers.
[0043] By adopting the above technical solution, the strontium titanate layer 2 has a good insulation effect and can store some static charge. If the thickness of the strontium titanate layer 2 is low, the insulation effect is poor, that is, it cannot block small electrostatic currents. If the thickness of the strontium titanate layer 2 is high, there is more material consumption, the cost increases, and the coating cover plate is thicker, resulting in a poor user experience. Therefore, the thickness of the strontium titanate layer 2 is set to 50 nanometers to 100 nanometers, which effectively balances the insulation effect and material cost, and also improves the user experience.
[0044] In addition, the strontium titanate layer 2 has excellent chemical stability, which can provide a stable substrate as the bottom layer and enhance the adhesion of subsequent coatings. At the same time, the strontium titanate layer 2 also optimizes the overall optical performance. The strontium titanate layer 2 has a high refractive index and high transparency, which can effectively refract the influence of external light sources on the user's viewing of the display device, thereby improving the user's experience.
[0045] like Figure 2As shown, in this preferred embodiment, the glass cover 1 includes a visible area 11 and a non-visible area 12. The non-visible area 12 is disposed outside the edge of the visible area 11 along the edge of the visible area 11. The ink layer 4 covers the corresponding non-visible area 12 of the glass cover 1.
[0046] By adopting the above technical solution, the visible area 11 is the position where the display device needs to display the content, and the non-visible area 12 is the area to be covered, that is, the area where the display device's ribbon cable exists. By covering the non-visible area 12 with the ink layer 4, the ribbon cable of the display device is covered, thereby making the display device more aesthetically pleasing when viewed by the user, and improving the user experience and visual experience.
[0047] In a preferred embodiment, the intermediate layer 3 is further provided, which is disposed between the strontium titanate layer 2 and the ink layer 4. The intermediate layer 3 has wear resistance and chemical stability.
[0048] By adopting the above technical solution, it is necessary to ensure that the glass cover 1 has high wear resistance to prevent wear during use or installation, which could lead to scratches on the glass cover 1 and affect the user's viewing experience. The intermediate layer 3 is disposed between the strontium titanate layer 2 and the ink layer 4, protecting the side of the glass cover 1 that contacts the display device. This prevents damage to the strontium titanate layer 2 when the glass cover 1 is installed onto the display device, effectively protecting the integrity of the coated cover. The strontium titanate layer 2 is thin and lacks wear resistance, requiring protection to prevent damage.
[0049] In this preferred embodiment, the intermediate layer 3 includes: an aluminum nitride layer 31, which is closely bonded to the strontium titanate layer 2 and has wear resistance and corrosion resistance; and a boron trioxide layer 32, which is disposed between the aluminum nitride layer 31 and the ink layer 4 and has chemical stability.
[0050] By adopting the above technical solution, the aluminum nitride layer 31 (AlN) possesses high hardness, high thermal conductivity, and good chemical stability, which can enhance the wear resistance and corrosion resistance of the glass cover plate 1. The atoms of the aluminum nitride layer 31 are bonded together by covalent bonds, giving it excellent chemical stability. At the same time, the aluminum nitride layer 31 has high mechanical strength, with a hardness close to that of quartz, and can be used as a wear-resistant coating to effectively protect the strontium titanate layer 2 from wear.
[0051] The boron trioxide layer 32 (B2O3) also has high hardness and good chemical stability, which further enhances the protective effect on the strontium titanate layer 2. In addition, due to the good optical properties of the boron trioxide layer 32, it can effectively block external light sources when optical refraction and reflection phenomena are present, reducing the impact of external light sources on the user's viewing of the display device, thereby improving the user's experience.
[0052] It should be noted that the boron trioxide layer 32 is hygroscopic and may hydrolyze after absorbing water. Therefore, the coating cover plate needs to be tightly attached to the display device and sealed to prevent the boron trioxide layer 32 from hydrolyzing.
[0053] The intermediate layer 3 uses an aluminum nitride layer 31 and a boron trioxide layer 32 to enhance the mechanical properties and chemical stability of the coated cover plate and protect the strontium titanate layer 2 from damage.
[0054] In this preferred embodiment, the thickness of the aluminum nitride layer 31 is 20 nanometers to 50 nanometers. The thickness of the boron trioxide layer 32 is 20 nanometers to 50 nanometers.
[0055] By adopting the above technical solution, the aluminum nitride layer 31 has good wear resistance, and the boron trioxide layer 32 has good chemical stability and corrosion resistance, meaning that both have high protective effects. If the thickness of the aluminum nitride layer 31 and the boron trioxide layer 32 is too low, the protective effect is poor, meaning that it cannot protect the strontium titanate layer 2 and the glass cover plate 1. If the thickness of the aluminum nitride layer 31 and the boron trioxide layer 32 is too high, there will be more material consumption, increased costs, and a thicker coated cover plate, resulting in a poor user experience. Therefore, the thickness of the aluminum nitride layer 31 is set to 20 nanometers to 50 nanometers, and the thickness of the boron trioxide layer 32 is set to 20 nanometers to 50 nanometers, which effectively balances the insulation effect and material cost, and also improves the user experience.
[0056] Example 2
[0057] The present invention provides a display device, including a coated cover plate with a color-changing border.
[0058] The implementation principle of the coated cover plate and display device with color-changing border in this embodiment of the utility model is as follows:
[0059] A composite coating layer consisting of a strontium titanate layer 2 (SrTiO3) as the bottom layer, an aluminum nitride layer 31 (AlN), and a boron trioxide layer 32 (B2O3) as the intermediate layer 3 is constructed on the glass cover plate 1, providing a protective surface layer. The strontium titanate layer 2, with its high dielectric constant and good insulation, provides a stable substrate and enhanced adhesion for the entire coated cover plate, while also exhibiting excellent optical properties, improving the user experience. The intermediate layer 3, through the high hardness, high thermal conductivity, and chemical stability of the aluminum nitride layer 31, and the hardness and chemical stability of the boron trioxide layer 32, jointly enhances the wear resistance and corrosion resistance of the cover plate, and effectively protects the strontium titanate layer 2. The non-visible area 12 of the uppermost border region is screen-printed on the surface of the boron trioxide layer 32 with water-sensitive color-changing ink. This ink layer 4 changes color upon contact with water, not only giving the cover plate a unique visual aesthetic but also serving as a direct indicator of moisture contact, enhancing the practicality and interactivity of the coated cover plate.
[0060] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
