Abstract
Description
Technical Field
[0001] This utility model relates to the field of cover plate technology, and in particular to a weather-resistant coated cover plate and display module. Background Technology
[0002] With the increasing prevalence of technological products and consumers' ever-increasing demands for product durability, functionality, and aesthetics, traditional glass covers can no longer meet the diversified needs of the market. Especially in the field of electronic products such as smartphones, tablets, and wearable devices, glass covers not only need to withstand the wear and scratches of daily use, but also need to have other specific functional indicators.
[0003] Although various glass surface treatment technologies exist in the current market, their ability to resist the influence of various climatic factors in the natural environment is still relatively low. Therefore, a weather-resistant coated cover plate and display module are proposed. Utility Model Content
[0004] Therefore, it is necessary to provide a weather-resistant coated cover plate and display module to address the above-mentioned technical problems. By coating the surface of a conventional cover plate with a polysulfonated fluoride layer, the overall weather resistance of the cover plate can be improved.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A weather-resistant coated cover plate includes a glass cover plate, a coated surface on the top of the glass cover plate, a mounting surface on the bottom of the glass cover plate, a protective coating layer coated on the coated surface, and a mounting boss extending downward from the edge of the mounting surface of the glass cover plate.
[0007] The protective coating includes a polysulfonated fluorinated ethylene layer coated on the surface of the coating. An intermediate coating layer and a top coating layer are also coated on the polysulfonated fluorinated ethylene layer. The top coating layer, the intermediate coating layer and the polysulfonated fluorinated ethylene layer are coated sequentially from top to bottom to form the protective coating.
[0008] Furthermore, the intermediate coating layer is a titanium dioxide layer.
[0009] Furthermore, the top coating layer is a titanium nitride layer.
[0010] Furthermore, the thickness of the polysulfonated fluorinated ethylene layer is between 100 nanometers and 150 nanometers.
[0011] Furthermore, the thickness of the titanium dioxide layer is between 20 nanometers and 30 nanometers, and the coating thickness of the titanium nitride layer is between 10 nanometers and 20 nanometers.
[0012] Furthermore, the bottom of the mounting boss has a mounting groove.
[0013] Furthermore, the central area of the glass cover has a visible area, and the area outside the visible area is a non-visible area;
[0014] The bottom of the glass cover plate, corresponding to the non-visible area, and the surface of the mounting boss are both provided with a photosensitive color-changing ink layer.
[0015] Furthermore, the surface of the photosensitive color-changing ink layer is also provided with a tin layer.
[0016] A display module includes a weather-resistant coated cover plate, a middle frame, and a mounting boss having a mounting groove at its bottom.
[0017] Furthermore, the top of the middle frame has an embedding groove corresponding to the position of the mounting boss, and the bottom wall of the embedding groove is fixed with an embedding block that is adapted to the mounting groove. The mounting boss and the embedding groove together form a labyrinth groove, and the labyrinth groove is filled with optical adhesive.
[0018] Furthermore, the middle part of the middle frame has a partition platform, which divides the middle frame into a TFT assembly cavity and a backlight assembly cavity.
[0019] A TFT display module is installed in the TFT assembly cavity, and a backlight module is installed in the backlight assembly cavity.
[0020] Compared with the prior art, the present invention has the following beneficial effects:
[0021] This utility model provides a weather-resistant coated cover plate and display module. A polysulfonated fluoride layer is coated on the surface of a conventional cover plate. The material properties of the polysulfonated fluoride layer itself can give the glass surface excellent weather resistance and chemical stability, thereby improving the cover plate's ability to resist the influence of various climatic factors in the natural environment.
[0022] Meanwhile, through the combination of the intermediate coating layer and the top coating layer, excellent photocatalytic and ultraviolet absorption capabilities are achieved, reducing the damage of ultraviolet rays to internal components. At the same time, the high hardness and wear resistance of the titanium nitride layer can be used to effectively resist external physical impacts and scratches, protecting the glass substrate.
[0023] The design of the mounting boss allows for external clamping equipment to hold the mounting boss during the coating process on the glass cover. This completely exposes the top and surrounding area of the glass cover, making the coating operation more convenient. At the same time, vacuum adsorption can be used to fix the bottom of the glass cover, making the fixing method flexible and diverse to meet the application needs of different production scenarios.
[0024] By combining the mounting boss and the embedding groove, the glass cover can be fixed after being embedded in the surface of the middle frame. This allows the glass cover and the middle frame to form a maze, which more effectively blocks external dust and other contaminants, preventing them from falling into the middle frame and affecting the overall display effect of the module.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0038] As described in the background section, although various glass surface treatment technologies exist on the market, their ability to resist the influence of various climatic factors in the natural environment is still relatively limited.
[0039] To solve this technical problem, this utility model provides a weather-resistant coated cover plate and a display module, which are applied to coated cover plates.

[0041] The protective coating 2 includes a polysulfonated fluorinated ethylene layer 21 coated on the surface of the coating surface 11. An intermediate coating layer 22 and a top coating layer 23 are also coated on the polysulfonated fluorinated ethylene layer 21. The top coating layer 23, the intermediate coating layer 22 and the polysulfonated fluorinated ethylene layer 21 are coated sequentially from top to bottom to form the protective coating 2.
[0042] This utility model provides a weather-resistant coated cover plate, which is coated with a polysulfonated fluoride layer 21 on the surface of a conventional glass cover plate 1. The material properties of the polysulfonated fluoride layer 21 itself can give the surface of the glass cover plate 1 excellent weather resistance and chemical stability, thereby improving the ability of the glass cover plate 1 to resist the influence of various climatic factors in the natural environment.
[0043] For details, please refer to Figures 1-7 The display module further includes a middle frame 3, and the bottom of the mounting boss 120 has a mounting groove 121.
[0044] The present invention provides a display module in which the mounting boss 120 is designed so that when coating the glass cover plate 1, the mounting boss 120 can be clamped by an external fixing device. This allows the top and surrounding area of the glass cover plate 1 to be completely exposed, which is more conducive to the coating operation. At the same time, vacuum adsorption can be used to fix the bottom of the glass cover plate, making the fixing method flexible and diverse to meet the application in different production scenarios.
[0045] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0046] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0047] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0048] Example 1
[0049] Please refer to Figures 1-3 A weather-resistant coated cover plate includes a glass cover plate 1, a coated surface 11 on the top of the glass cover plate 1, a mounting surface 12 on the bottom of the glass cover plate 1, a coating protective layer 2 coated on the coated surface 11, and a mounting boss 120 extending downward from the edge of the mounting surface 12.
[0050] The protective coating 2 includes a polysulfonated fluorine 21 (PSFE) layer coated on the surface of the coating surface 11. An intermediate coating layer 22 and a top coating layer 23 are also coated on the polysulfonated fluorine 21. The top coating layer 23, the intermediate coating layer 22 and the polysulfonated fluorine 21 are coated sequentially from top to bottom to form the protective coating 2.
[0051] In this embodiment, a polysulfonated fluoride layer 21 is coated on the surface of a conventional glass cover plate 1. The material properties of the polysulfonated fluoride layer 21 itself can give the surface of the glass cover plate 1 excellent weather resistance and chemical stability, thereby improving the ability of the glass cover plate 1 to resist the influence of various climatic factors in the natural environment.
[0052] Example 2
[0053] The weather-resistant coated cover plate provided in Embodiment 1 is further optimized, specifically, as follows: Figure 4As shown, the intermediate coating layer 22 is a titanium dioxide layer (TiO2); the above-mentioned titanium dioxide layer has excellent photocatalytic performance and ultraviolet absorption capacity. In addition, it can also provide a certain heat insulation effect and reduce the damage of ultraviolet rays to the inside of the product.
[0054] The top coating layer 23 is a titanium nitride layer (TiN). Titanium nitride is a material with high hardness and high wear resistance, which can effectively protect the glass surface from scratches and wear. At the same time, it also has excellent corrosion resistance and good optical properties. Therefore, it is designed as the top layer to provide an effective protective barrier for the middle coating layer 22, the polysulfonated fluoride layer 21 and the glass cover plate 1 below.
[0055] The thickness of the polysulfonated fluoroethylene layer 21 is between 100 nanometers and 150 nanometers.
[0056] The thickness of the titanium dioxide layer is between 20 nanometers and 30 nanometers, and the coating thickness of the titanium nitride layer is between 10 nanometers and 20 nanometers.
[0057] The actual thickness of the polysulfonated fluorine layer 21, the titanium dioxide layer, and the titanium nitride layer can be adjusted adaptively according to the specific application.
[0058] Example 3
[0059] The weather-resistant coated cover plate provided in Embodiment 1 or 2 is further optimized, such as... Figure 5 As shown, the bottom of the mounting boss 120 has a mounting groove 121;
[0060] The central area of the glass cover plate 1 has a visible area 13, and the area outside the visible area 13 is a non-visible area 14. The bottom of the glass cover plate 1, corresponding to the position of the non-visible area 14, and the surface of the mounting boss 120 are provided with a photosensitive color-changing ink layer 15. By designing the photosensitive color-changing ink layer 15 in the non-visible area 14, the normal display of the image in the visible area 13 will not be affected.
[0061] The surface of the photosensitive color-changing ink layer 15 is also provided with a tin layer 16. In this embodiment, the thermosensitive color-changing ink layer 15 serves as a special functional layer, which can change color according to changes in ambient temperature, providing intuitive temperature monitoring. Finally, the tin layer 16 serves as a protective layer, ensuring that the thermosensitive color-changing ink layer 15 can maintain stable performance in complex environments and extend its service life.

The optical adhesive can form a connection and fixation between the mounting boss 120 and the embedding groove 34, thereby realizing the fixation of the glass cover plate 1.
[0064] When the glass cover plate 1 is installed on the top of the middle frame 3, the mounting boss 120 on the glass cover plate 1 will be placed inside the embedding groove 34, and the mounting groove 121 and the embedding block 35 will be engaged. The glass cover plate 1 and the middle frame 3 will be enclosed to form a maze, which will more effectively block external dust and other objects, and prevent them from falling into the middle frame 3 and affecting the overall display effect of the module.
