[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 that prevents ink scratches. (See reference...) Figure 1 The system includes: a glass cover plate 1, a coating layer 2, an ink layer 3, and an acrylic resin layer 4; the glass cover plate 1 has two sides, one side of the glass cover plate 1 is in contact with the coating layer 2, and the coating layer 2 has wear resistance and optical transparency; the ink layer 3 is screen-printed on the other side of the glass cover plate 1, and the acrylic resin layer 4 is disposed on the side of the ink layer 3 away from the glass cover plate 1, and the acrylic resin layer 4 has wear resistance.
[0031] By adopting the above technical solution, the ink layer 3 of the glass cover plate 1 faces the display device, which can cover the screen cable in the display device, making the screen more aesthetically pleasing when the user views it. Acrylic resin has good wear resistance, which can effectively prevent ink scratches or wear. The coating layer 2 covers the glass cover plate 1 and faces the external environment, which can effectively prevent the glass cover plate 1 from being worn or corroded during use.
[0032] From the glass cover 1 towards the external environment, i.e. towards the user, a coating layer 2 is applied, effectively preventing the glass cover 1 from being scratched. From the glass cover 1 towards the display device, an ink layer 3 and an acrylic resin layer 4 are sequentially applied. The acrylic resin layer 4 provides necessary protection, preventing the ink from being scratched or worn.
[0033] Optionally, the material of the ink layer 3 is a thermochromic ink.
[0034] By adopting the above technical solution, the thermochromic ink will change color when the ambient temperature changes. Users can intuitively feel the change in ambient temperature by observing the color change of the thermochromic ink, thereby increasing the fun and practicality of the coated cover.
[0035] When temperature parameters change, the color of the thermochromic ink in ink layer 3 changes accordingly, resulting in variations in color and brightness of the pattern. As the user uses the display device, the temperature parameters change over time and in different environments, causing the color or brightness of ink layer 3 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 change of thermochromic ink with temperature parameters is a component known to those skilled in the art, and its structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
[0037] Specifically, thermochromic inks contain thermochromic pigments, which display different colors when the temperature changes. For example, display devices generate heat during use, and this temperature continues to rise as usage time increases or a malfunction occurs. Thermochromic inks can display different colors at different temperatures.
[0038] like Figure 2 As shown, optionally, the glass cover plate 1 includes a visible area 11 and a non-visible area 12, the non-visible area 12 being disposed outside the edge of the visible area 11 along the edge of the visible area 11; the ink layer 3 covering the non-visible area 12 of the glass cover plate 1.
[0039] 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 3, 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.
[0040] 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.
[0041] Optionally, the area of the acrylic resin layer 4 is the same as the area of the ink layer 3, and the acrylic resin layer 4 covers the ink layer 3.
[0042] By adopting the above technical solution, the acrylic resin layer 4 covers the surface of the ink layer 3, effectively protecting the ink layer 3 from scratches. Therefore, the acrylic resin layer 4 needs to completely cover the ink layer 3, that is, the surface area of the acrylic resin layer 4 and the ink layer 3 are the same.
[0043] In addition, the surface area of the acrylic resin layer 4 can be slightly larger than that of the ink layer 3, which can also effectively protect the ink layer 3 from scratches. However, the portion of the surface area of the acrylic resin layer 4 that exceeds the surface area of the ink layer 3 needs to be less than a predetermined surface area; that is, it cannot exceed it by too much. If it exceeds it by too much, it may result in an unsightly coating cover. By making the surface area of the acrylic resin layer 4 the same as or slightly larger than that of the ink layer 3, the ink layer 3 is effectively protected and scratches are prevented.
[0044] Optionally, the area of the visible region 11 is larger than the area of the non-visible region 12.
[0045] By adopting the above technical solution, the visible area 11 is the area used by the display device to display content, and the non-visible area 12 is the area covering the ribbon cable. The area of the non-visible area 12 can be adjusted according to the ribbon cable of the display device, but the area of the non-visible area 12 must be smaller than the area of the visible area 11. That is, if the non-visible area 12 is too large, it exceeds the area mapped by the ribbon cable, and there is a possibility of obscuring the displayed content. By reducing the area of the non-visible area 12 and making it the same as or slightly larger than the area mapped by the ribbon cable, the content that needs to be displayed in the visible area 11 can be effectively avoided.
[0046] Optionally, the coating layer 2 includes: an aluminum oxide layer 21 covering the surface of the glass cover plate 1, the aluminum oxide layer 21 having wear resistance; a molybdenum oxide layer 22 covering the surface of the aluminum oxide layer 21, the molybdenum oxide layer 22 having corrosion resistance; and a titanium oxide layer 23 covering the surface of the molybdenum oxide layer 22, the titanium oxide layer 23 having optical adjustability.
[0047] By adopting the above technical solution, the coating layer 2 is disposed on the surface of the glass cover plate 1, facing the external environment, thus protecting the glass cover plate 1 from scratches during use. The alumina layer 21 has excellent wear resistance, effectively preventing the glass cover plate 1 from being worn during use. The molybdenum oxide layer 22 has corrosion resistance and covers the surface of the alumina layer 21, effectively preventing the alumina layer 21 from being corroded, thereby protecting the glass cover plate 1. The titanium oxide layer 23 has good optical adjustability, that is, good light reflection performance, effectively achieving a high clarity effect when the displayed content passes through the coating cover plate. In addition, it improves the clarity when users view the display device and reduces the impact of external light sources reflected on the glass cover plate 1, improving the user experience.
[0048] Optionally, the thickness of the alumina layer 21 is 30 nanometers to 50 nanometers, the thickness of the molybdenum oxide layer 22 is 50 nanometers to 70 nanometers, and the thickness of the titanium oxide layer 23 is 60 nanometers to 80 nanometers.
[0049] By adopting the above technical solution, the alumina layer 21 has wear resistance and the molybdenum oxide layer 22 has corrosion resistance, both of which need to protect the glass cover 1. When the thickness of the alumina layer 21 and the molybdenum oxide layer 22 is low, the protective effect is poor. When the thickness of the alumina layer 21 and the molybdenum oxide layer 22 is high, there is more material consumption and the coating layer 2 is thicker, resulting in a poor user experience. Therefore, the thickness of the alumina layer 21 is set to 30 nanometers to 50 nanometers and the thickness of the molybdenum oxide layer 22 is 50 nanometers to 70 nanometers, which effectively balances the protective performance and material cost and improves the user experience.
[0050] In addition, the titanium oxide layer 23 has good optical adjustability, which can effectively adjust the reflection and refraction of light. When the thickness of the titanium oxide layer 23 is low, the reflection effect is poor, that is, the optical adjustability is poor. When the thickness of the titanium oxide layer 23 is high, the material consumption is high and the coating layer 2 is thick, resulting in a poor user experience. Therefore, the thickness of the titanium oxide layer 23 is set to 60 nanometers to 80 nanometers, which effectively balances the optical adjustability performance and material cost, and improves the user experience.
[0051] Example 2
[0052] The present invention provides a display device, including a coated cover plate that is resistant to ink scratches.
[0053] The implementation principle of the ink-resistant coated cover plate and display device of this utility model embodiment is as follows:
[0054] By selecting high-performance oxides such as alumina layer 21, molybdenum oxide layer 22, and titanium oxide layer 23 as materials for the coating layer 2, and combining them with thermochromic ink and acrylic resin layer 4, comprehensive protection and functional enhancement of the glass cover 1 are achieved. The coating layer 2 adopts a multi-layer structure design, with each layer, based on its unique physical and chemical properties, undertaking functions such as wear resistance, corrosion resistance, and optical performance adjustment, collectively constructing a robust and aesthetically pleasing protective barrier. On the other side of the glass cover 1, the ingenious combination of thermochromic ink and acrylic resin layer 4 gives the glass cover 1 the fun and practicality of temperature sensing, and the protection of the acrylic resin layer 4 effectively prevents damage to the ink layer 3. This effectively utilizes the advantages of multiple materials, achieving a fusion of performance and function, while effectively improving the wear resistance of the coated cover and extending its service life.
[0055] 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.
