[0026] Among them, the glass cover plate includes a substrate, and a surface of one side of the substrate has a plurality of disorderly arranged first microstructures.

As for the problem of screen clarity and local brightness of the screen, a second microstructure is further formed on the first microstructure, and the particle size of any second microstructure is controlled to be 1μm to 5μm. Among them, since the second microstructure is formed on the first microstructure, the second microstructure is a structural modification of the first microstructure, that is, the second microstructure can be obtained by secondary processing of the first microstructure. The existence of the second microstructure does not affect the disordered arrangement of the first microstructure, and by controlling the particle size of the second microstructure within the above range, the second microstructure can be evenly arranged on the first microstructure, that is, the particles of the second microstructure are smaller, and the arrangement uniformity on the first microstructure is good, indicating that the density of the microstructure per unit area is increased. In addition, due to the increase in the density of the microstructure, the disorder of the microstructure is higher, thereby further enhancing the anti-glare effect of the glass cover plate. In addition, since the second microstructure is smaller and has a high uniformity of arrangement, the second microstructure can not only reflect but also achieve a diffraction effect, so the transmission of light is more uniform. Moreover, since the microstructure density per unit area is relatively large and there are two different microstructures, there are more light transmission directions, further ensuring the uniformity of transmission, which is beneficial to reduce the flash point, effectively solve the problem of screen brightness, and also help to improve the clarity of the screen, which is beneficial to improving the comfort of the user's eyes.

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] In the present invention, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside", "outside", "middle", "vertical", "horizontal", "lateral", "longitudinal" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings. These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0041] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in this utility model can be understood according to specific circumstances.

[0042] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0043] The technical solution provided by the utility model will be further described below in conjunction with embodiments and drawings.

[0044] Glare refers to the phenomenon that when light shines on the screen surface, it will cause strong specular reflection light on the screen surface, which will interfere with the user, causing the user to be unable to see the screen clearly, affecting vision and even damaging the eyes. In order to solve this problem, a layer of anti-glare glass cover is usually prepared on the screen of the electronic device. This is because the anti-glare glass cover has a disordered microstructure. The disordered microstructure can be used to diverge the light of the screen, converting specular reflection into diffuse reflection, making the light transmission direction diverse, thereby achieving an anti-glare effect.

[0045] However, although the disordered arrangement of microstructures can effectively solve the anti-glare problem, it will also cause the transmission direction of the screen's light to be spatially disordered, which may cause some areas to receive more light, resulting in local brightness on the screen, thus affecting the user's experience.

[0046] Based on the above problems, an embodiment of the present application provides a glass cover plate, which has a good anti-glare effect and can effectively solve the problem of partial brightness of the screen.

[0047] In the first aspect, an embodiment of the present application provides a glass cover plate, which includes a substrate, a surface of one side of the substrate is provided with a plurality of disorderly arranged first microstructures, a plurality of second microstructures are provided on the plurality of first microstructures, and a particle size of any second microstructure is 1 μm to 5 μm.

[0048] Among them, the main function of the first microstructure is to achieve an anti-glare effect, so it is arranged in a disordered manner. However, different processing methods or structural designs have obvious differences in the disorder of the first microstructure in the arrangement of the first microstructure. For example: the traditional frosting process and other chemical etching methods, due to the non-structural design, mainly rely on the random attachment of the crystal product to the glass to produce a masking effect, which causes the arrangement of the first microstructure to be extremely disordered; however, there are methods that can adjust the disorder of the first microstructure by adjusting the structural periodic distribution. For example, photolithography, laser etching, nanoimprinting, printing, etc. can all be customized for the arrangement of the first microstructure, so that a certain degree of disorder can be reduced, so that part of the first microstructure presents a disordered arrangement, and another part presents a regular arrangement; but such processes are complex and expensive.

[0049] Among them, Figure 1 As shown, the first microstructure 2 is a groove structure, the second microstructure 1 has both a groove structure and a protrusion structure, and any first microstructure 2 is provided with a second microstructure 1, such as Figure 2 As shown, only part of the first microstructure 2 has the second microstructure 1. Since the second microstructure 1 is arranged on the first microstructure 2 and is a modification of the first microstructure 2, the existence of the second microstructure 1 will not affect the disordered arrangement of the first microstructure 2, thereby effectively ensuring the anti-glare effect of the glass cover plate, and since the density of the microstructure per unit area is increased, the light transmission direction is more, and the light reflection clarity is reduced to less than 10%, further improving the anti-glare effect of the glass cover plate. Preferably, when the second microstructure 1 is provided on any first microstructure 2, the density of the microstructure per unit area is more, which helps to provide the anti-glare effect of the glass cover plate and reduce the flash point. In addition, since the structure of the second microstructure 1 is relatively small, it not only has a reflective property but also a diffraction property, so that the uniformity of light transmission is better, and due to the existence of the two microstructures and the high density of the microstructure per unit area, the uniformity of light transmission is further ensured, which helps to reduce the flash point of the glass cover plate to 20%, effectively solving the problem of local brightness of the screen, improving the clarity of the screen, and thus improving the user's use effect.

[0050] Furthermore, the height of any second microstructure is 0.2 μm to 1.5 μm. When the height of the second microstructure is within the above range, the whitening phenomenon of the glass cover can be effectively reduced, thereby helping to further improve the clarity of the glass cover. In other words, the present application sets a second microstructure on the first microstructure, thereby helping to reduce the flash point, improve the uniformity of light transmission, and improve the clarity of the screen, and by further controlling the height of the second microstructure, the whitening phenomenon of the glass cover is reduced, and the clarity of the screen is further improved, thereby helping to improve the user experience.

[0051] The glass cover provided in the embodiment of the present application is provided with a disorderly arranged first microstructure on a substrate, and further structurally modifying the first microstructure, and providing a second microstructure on the first microstructure. Since the particle size of the second microstructure is 1 μm to 5 μm, and the height is 0.2 μm to 1.5 μm, preferably, the particle size of the second microstructure is 3 μm to 5 μm, and the height is 0.5 μm to 1 μm, it means that the particle size of the second microstructure is small and the uniformity is high. Therefore, the density of the microstructure per unit area is high, which helps to ensure anti-glare, reduce the flash point, and further improve the clarity of the glass cover.

[0052] Furthermore, the particle size of the second microstructure refers to the average particle size Rsm of the second microstructure, and the height of the second microstructure refers to the average height Rz of the second microstructure. The second microstructure may be only a groove structure, a convex structure, or a groove structure and a convex structure at the same time. The present application does not limit the particle size of the second microstructure. Figure 3 As shown, when the second microstructures 1 are all groove structures, the particle size of the second microstructure 1 refers to the average particle size of the groove structure, and the height of the second microstructure refers to the average value of the distance from the notch of the groove to the bottom of the groove. The preparation method of this structure is simple, which helps to improve the efficiency of production and processing; Figure 4 As shown, when the second microstructures 1 are all protruding structures, the particle size of the second microstructure 1 refers to the average particle size of the protruding structure, and the height of the second microstructure 1 refers to the average value of the distance between the top and the bottom of the protruding structure; Figure 5 As shown, the second microstructure 1 has both a groove structure and a convex structure, which makes the direction of light transmission more diverse, which is beneficial to the uniformity of light, thereby reducing the flash point to a high degree. The present application does not limit the structural form of the second microstructure, as long as the particle size and height of the second microstructure meet the scope of the present application.

[0053] Furthermore, the plurality of second microstructures are arranged in a disordered manner. Since the second microstructure is small in size, it has the optical properties of refraction and diffraction, ensuring the uniformity of light transmission. By further making the second microstructure present a disordered arrangement, compared with the ordered structure, the disordered structure allows more light transmission paths, better uniformity of light transmission, and can effectively solve the flash point problem.

[0054] Among them, the second microstructures present an irregular arrangement, which includes two situations. The first situation is that multiple second microstructures are arranged irregularly as a whole, and there is no regularity in the spacing between two adjacent second microstructures; the second situation is that some of the second microstructures present an irregular arrangement, and another part of the second microstructures present a regular arrangement, that is, the spacing between the adjacent second microstructures follows a certain rule.

[0055] In addition, when the particle size of any first microstructure is 10 μm to 80 μm, and the height of any first microstructure is 0.5 μm to 3 μm, when the particle size of the first microstructure is within the above range, it is helpful to modify the first microstructure to obtain the second microstructure, thereby not only ensuring that the first microstructure has a high anti-glare effect, but also enabling the second microstructure to reduce the flash point and improve the clarity of the glass cover.

[0056] The particle size of the first microstructure and the particle size of the second microstructure have the same meaning, both referring to the average particle size Rsm of the first microstructure, and the height of the first microstructure refers to the average value Rz of the height of the first microstructure.

[0057] Furthermore, the glass cover plate further comprises: a third microstructure, which is arranged on the second microstructure and / or arranged on the first microstructure without the second microstructure. The third microstructure is arranged on the second microstructure, so that the glass cover plate has a certain anti-reflection effect.

[0058] Furthermore, the third microstructure is a porous structure, a random undulating structure, a conical structure or a pyramidal structure, etc. Preferably, when the third microstructure is a conical structure or a pyramidal structure, the anti-reflection effect of the third microstructure is the best.

[0059] Furthermore, along the direction toward the substrate, the cross-sectional width of the third microstructure presents an increasing trend. Since the bottom of the third microstructure is close to one side of the substrate and the top of the third microstructure is far away from one side of the substrate, the cross-sectional width of the third microstructure has an increasing trend along the direction from the top to the bottom of the third microstructure.

[0060] In addition, when the cross-sectional width of the third microstructure presents an increasing trend, the refractive index of the third microstructure toward the substrate achieves an increasing effect, thereby effectively increasing the anti-reflection effect of the glass cover. Preferably, when the cross-sectional width of the third microstructure gradually increases and presents a regular change, the difference in refractive index is reduced, which is conducive to avoiding the reflection phenomenon caused by the sudden change of the refractive index, and can further enhance the anti-reflection effect of the glass cover.

[0061] The third microstructure is arranged in the following three ways: Figure 6 As shown, the third microstructure 3 is a triangular structure, and the third microstructure 3 is only arranged on the second microstructure 1. Since the third microstructure 3 is relatively small, it will not have an adverse effect on the arrangement of the second microstructure 1, and further promotes the uniformity of light transmission, thereby effectively reducing the flash point problem of the glass cover plate and improving the clarity of the glass cover plate. The gradual setting of the third microstructure 3 has an anti-reflection effect and improves the visual effect of the glass cover plate; Figure 7As shown, the third microstructure 3 is only arranged on the first microstructure 2. Since the structure of the third microstructure 3 is much smaller than the first microstructure 2, it will not affect the arrangement of the first microstructure 2, effectively ensuring the anti-glare effect of the glass cover, and further ensuring the uniformity of light transmission and reducing the flash point; Figure 8 As shown, the third microstructure 3 is arranged on the first microstructure 2 and the second microstructure 1 at the same time, and because the particle size of the third microstructure 3 is much smaller than that of the second microstructure 1 and the first microstructure 2, this type of structural setting has a larger number of microstructures within a unit density, thereby effectively ensuring the anti-glare and flash point reduction effects of the glass cover plate, and can also fully benefit from the anti-reflection effect of the third microstructure 3, thereby improving the visual effect of the glass cover plate.

[0062] Among them, Fig. 9 As shown, the lines forming the cross-sectional width of the third microstructure 3 may be arc-shaped lines; Fig.10 As shown, the line forming the cross-sectional width of the third microstructure 3 can be a straight line. The present application does not limit the interface shape of the third microstructure 3, as long as the cross-sectional width of the third microstructure 3 shows an increasing trend.

[0063] In order to achieve coverage of a wider range of wavelengths, it is necessary to prepare multiple layers of anti-reflection layers, which will increase the thickness of the glass cover plate and the cost of preparation. In addition, due to the limitation of the number of layers of the anti-reflection layer, the reflectivity of the short-wave band (380-450nm) and the long-wave band (650-780nm) is higher than that of other bands, which will cause a large difference in reflectivity in the entire visible light band, so the reflected screen light has a special color. However, the present application only achieves the effect of gradual change of refractive index by preparing a third microstructure with a gradual change in cross-sectional width, which not only helps to reduce the thickness of the glass cover plate and the processing cost, but also ensures the anti-reflection effect of the glass cover plate, so that the thickness of the finally prepared glass cover plate is at the nanometer level at the thinnest and at the thickest, reaching tens of micrometers.

[0064] Furthermore, the anti-reflection effect of the glass cover can be further improved by controlling the particle size and height of the third microstructure. When the particle size of any third microstructure is 10nm to 1000nm, and the height of any third microstructure is 50nm to 1000nm, preferably, the particle size is 100nm to 300nm, and the height is 500nm to 1000nm, the anti-reflection effect of the glass cover is better.

[0065] The particle size of the third microstructure has the same meaning as the particle size of the second microstructure, and both refer to the average particle size Rsm of the third microstructure. The height of the third microstructure refers to the average value Rz of the height of the third microstructure.

[0066] By controlling the particle size of the third microstructure within the above range, the mirror reflectivity of the glass cover plate is reduced from 0.5% to 0.1%, and the overall reflectivity is reduced from 5.5% to 1.5%. In addition, since the particle size of the third microstructure is small, the hydrophobic property of the glass cover plate is higher, so that it has the effect of an anti-fingerprint layer, and the preparation of the anti-fingerprint layer can be eliminated, or the effect of the anti-fingerprint layer can be significantly improved.

[0067] In addition, in order to make the glass cover more widely applicable, the multiple third microstructures are arranged in a disordered manner. Compared with an ordered arrangement, the disordered arrangement enables the third microstructure to reflect more light bands, which is suitable for application scenarios in various bands and has a wider applicability.

[0068] It should be noted that there are two situations in which the third microstructures are arranged in an irregular manner as a whole, and there is no regular pattern in the spacing between two adjacent third microstructures; the second situation is that some of the third microstructures are arranged in an irregular manner, and the other part of the third microstructures are arranged in a regular manner, that is, the spacing between adjacent third microstructures follows a certain pattern.

[0069] In addition, the glass cover plate further comprises an anti-reflection layer, which is disposed on the first microstructure and the second microstructure, thereby helping to increase the anti-reflection effect of the glass cover plate. Preferably, the anti-reflection layer is disposed on the first microstructure, the second microstructure and the third microstructure, and in this case, the anti-reflection effect of the glass cover plate can be effectively improved under the joint action of the anti-reflection layer and the third microstructure.

[0070] Furthermore, the glass cover plate also includes an anti-fingerprint layer, which is arranged on the first microstructure and the second microstructure, thereby improving the anti-fingerprint effect of the glass cover plate. Preferably, the anti-fingerprint layer is located above the first microstructure, the second microstructure and the third microstructure. At this time, since the third microstructure has hydrophobic properties, it can effectively improve the performance of the anti-fingerprint layer. Compared with the structure in which the anti-fingerprint layer is directly prepared on the substrate with the first microstructure, the present application prepares the anti-fingerprint layer on the third microstructure. Since the presence of the third microstructure makes the glass substrate more hydrophobic, the water drop angle of the glass cover plate is increased from 120° to more than 130°.

[0071] In a second aspect, an embodiment of the present application discloses an electronic product, which includes: the glass cover plate of the first aspect.

[0072] The technical solution of the present application will be further explained below in conjunction with more specific embodiments and experimental test results.

[0075] Embodiment 2:

[0085] Comparative Example 2:

[0086] The only difference between this comparative example and the first embodiment is that the glass cover plate of this comparative example has only the first microstructure.

[0093] Table 1 Performance test results of glass cover

[0094] Flash point(%) Clarity (%) Glossiness(%) Overall reflectivity (%) Embodiment 1 4.0 30 20 2.3 Embodiment 2 4.5 28 20 2.3 Embodiment 3 4.0 30 20 3.5 Embodiment 4 4.0 30 20 4.5 Embodiment 5 4.0 30 20 5.9 Comparative Example 1 6.0 26 18 2.3 Comparative Example 2 8.0 25 21 5.9

[0095] Analysis of the data of the embodiments and comparative examples shows that the flash point and clarity of embodiments one to five are better than those of comparative example one. This is because the parameters of the second microstructure of the glass cover plate of the embodiments are all within the scope of the present application, so the second microstructure can give full play to the effect of reducing the flash point and improving the clarity, thereby avoiding the particle size of the second microstructure being too large, making it difficult to ensure the uniformity of light transmission, and is beneficial to improving the visual effect of the glass cover plate; the flash point, clarity and gloss of embodiments one to five are better than those of comparative example two. This is because the structures of the glass cover plates of the embodiments all include the second microstructure. Therefore, under the joint action of the first microstructure and the second microstructure, it helps to ensure that the first microstructure has a good anti-glare effect, and give full play to the flash point reduction and clarity improvement effects of the second microstructure, so that the prepared glass cover plate has a higher visual effect.

[0096] Analysis of the data of Example 1 and Example 2 shows that the flash point and clarity of Example 1 are better than those of Example 2. This is because the parameters of the second microstructure of Example 1 are within the preferred range of the present application, and the uniformity of light transmission is higher, so the prepared glass cover has a lower flash point and higher clarity.

[0097] Analysis of the data of Example 1, Example 3 to Example 5 shows that the reflectivity of Example 1 is better than that of Example 3. This is because the particle size of the third microstructure of Example 1 is within the preferred range of the present application, which helps to improve the anti-reflection effect of the glass cover plate, thereby reducing the overall reflectivity of the glass cover plate; the data of Example 1 and Example 3 are better than those of Example 4 and Example 5. This is because both Example 1 and Example 3 have the third microstructure, and the parameters of the third microstructure are within the range of the present application, so the anti-reflection effect of the third microstructure is fully utilized, thereby effectively improving the anti-reflection performance of the glass cover plate.
