[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0024] Anti-glare glass is a glass surface that has been specially treated to make the surface rough, thereby changing the mirror reflection into diffuse reflection, creating a clear visual effect, thereby improving the user's viewing experience when using display devices.

[0025] Commonly used anti-glare glass processing techniques in the industry include frosting and etching, spray coating, and yellow light processing. Some electronic products require specific areas that cannot undergo microstructuring and require airtightness, such as camera holes and infrared sensor holes. The yellow light processing requires the use of a mask plate, where camera holes and infrared sensor holes are placed according to the product's form and dimensions. However, a separate mask plate must be made for each product, reducing its versatility.

[0026] In order to reduce the occurrence of the above situation, the embodiment of the present application improves the preparation method of anti-glare glass, which will be described below with reference to the accompanying drawings.

[0027] Please refer to FIG1 , which is a schematic diagram of a first process of a method for preparing anti-glare glass provided in an embodiment of the present application. The present application provides a method for preparing anti-glare glass, comprising:

[0028] 101. A protective portion is provided corresponding to a preset area of ​​a glass substrate, wherein the glass substrate has a patterned area and a preset area, and the patterned area surrounds the preset area.

[0029] Since the mask plates in the related art cannot be shared, or have poor versatility, in order to improve the versatility of the mask plates and thus reduce development costs, the embodiments of the present application separate the avoidance spaces originally made on the mask plates and make them into protective parts, so that different display devices can share the mask plates when making anti-glare glass.

[0030] Exemplarily, it is first necessary to provide a glass substrate, and the two opposite sides of the glass substrate are both flat surfaces. The glass substrate has a patterned area and a preset area. The patterned area is that the surface of the glass substrate is processed so that the surface of the glass substrate corresponding to the patterned area becomes rough, and changes from mirror reflection to diffuse reflection, creating a clear and transparent visual effect. The glass substrate is not processed in the preset area, so that the surface of the glass substrate in the preset area is flat or approximately flat, reducing the impact on the functional components of the display device. Among them, the patterned area can be set around the preset area. For example, the preset area corresponds to the camera or infrared sensor of the display device. If the camera and the infrared sensor are roughened at the glass substrate, it will affect the accuracy of the data collected by the camera and the infrared sensor. Therefore, in the embodiment of the present application, a protective portion is set in the preset area of ​​the glass substrate corresponding to the camera and the infrared sensor of the display device to avoid roughening the preset area.

[0031] In the embodiment of the present application, the glass substrate is artificially divided into a patterned area and a preset area to facilitate the description of the process performed on the two parts, and it should not be understood as a limitation on the glass substrate.

[0032] Exemplarily, a protective portion is provided at a predetermined region corresponding to the glass substrate to prevent the predetermined region from being roughened.

[0033] 102. Dispose photoresist on the glass substrate.

[0034] The present invention uses the yellow light process or yellow light process as an example to illustrate the roughening of glass substrates. This should not be construed as limiting the type of photolithography process used for roughening glass substrates. The yellow light process is a photolithography process in which a photosensitive material (also known as photoresist) coated on the glass surface is exposed and developed, leaving a portion that protects the underlying layer. The film is then etched and removed to ultimately obtain a permanent pattern.

[0035] Therefore, it is necessary to coat a photoresist on the glass substrate so that the glass substrate can be patterned or roughened in subsequent processes.

[0036] 103. A mask plate is arranged above the photoresist, wherein the mask plate has a plurality of light-transmitting holes, and the plurality of light-transmitting holes are evenly arranged.

[0037] Correspondingly, the yellow light process requires setting a mask and performing exposure to expose a specific pattern in the photoresist. This allows for roughening of the patterned area of ​​the glass substrate during photoresist removal, resulting in a concave-convex surface. A concave-convex surface can be understood as a rough, uneven surface that diffusely reflects light rather than specularly, achieving an anti-glare, soft-light, and eye-protecting effect.

[0038] For example, a mask is positioned above the photoresist, such as directly above it. The mask has multiple light-transmitting holes that are evenly arranged, such as in a multi-row, multi-column array, and evenly distributed across the entire mask. The multiple light-transmitting holes are of the same size, such as circular holes of the same size; or square holes of the same size. Of course, the light-transmitting holes can have other shapes, which are not listed here.

[0039] It should be noted that in the related art, in addition to light-transmitting holes, air-avoidance holes are provided on the mask plate corresponding to the functional components of each display device, such as cameras and infrared sensors. The air-avoidance holes are provided for functional components such as cameras and infrared sensors. The glass substrate corresponding to the air-avoidance holes does not need to be made into a concave or convex shape to avoid affecting the functional performance of the functional components. For different display devices, the location of functional components such as cameras or infrared sensors varies. Therefore, a mask plate needs to be developed for the anti-glare glass of each display device, which increases development costs.

[0040] Therefore, the embodiment of the present application separates the avoidance positions corresponding to the camera and infrared sensor from the mask plate. The mask plate has evenly arranged light-transmitting holes and eliminates the avoidance holes. Therefore, different display devices can share the same mask plate, which improves the versatility of the mask plate and reduces development costs.

[0041] 104. A light source is exposed from above the mask plate to develop the photoresist and form a concave-convex surface in the patterned area and a flat surface in the preset area to form an anti-glare glass.

[0042] A yellow light source is exposed from above the mask. The yellow light shines through the light-transmitting holes onto the photoresist, developing it and forming a specific pattern. The photoresist on the glass substrate is then removed, leaving the patterned areas of the glass substrate with a concave-convex surface. The protective portion protects the pre-set areas, leaving them flat or nearly flat, thus creating anti-glare glass.

[0043] In the method for preparing anti-glare glass provided in the embodiment of the present application, the existing mask plate is designed to include a avoidance position for the functional parts of the corresponding product, and is changed to a protective portion that is independent of the mask plate and arranged in a preset area corresponding to the glass substrate. There is no need to design a mask plate for each product, that is, different products can share the mask plate, which improves the versatility of the mask plate and can reduce development costs.

[0044] There are at least two ways to arrange the position of the protection portion.

[0045] Please refer to Figures 2 and 3. Figure 2 is a schematic diagram of the second process flow of the method for preparing anti-glare glass provided in an embodiment of the present application, and Figure 3 is a schematic diagram of the first process flow of the method for preparing anti-glare glass provided in an embodiment of the present application. In the first arrangement, the protective portion is arranged on the glass substrate. This embodiment of the present application also provides a method for preparing anti-glare glass, comprising:

[0046] 201. A printing screen is arranged on a glass substrate, wherein the printing screen is provided with through holes corresponding to preset areas.

[0047] First, a glass substrate 110 is required, and both opposite sides of the glass substrate 110 are flat surfaces. The glass substrate 110 has a patterned area 101 and a preset area 102. The patterned area 101 is a process treatment on the surface of the glass substrate 110, so that the surface of the glass substrate 110 corresponding to the patterned area 101 becomes rough, and changes from mirror reflection to diffuse reflection, creating a clear and transparent visual effect. The glass substrate 110 is not treated in the preset area 102, so that the surface of the glass substrate 110 in the preset area 102 is flat or approximately flat, reducing the impact on the functional components of the display device. Among them, the patterned area 101 can be set around the preset area 102. For example, the preset area 102 corresponds to the camera or infrared sensor of the display device. If the camera and the infrared sensor are roughened at the glass substrate 110, the accuracy of the data collected by the camera and the infrared sensor will be affected. Therefore, in the embodiment of the present application, a protection portion 130 is disposed in the predetermined area 102 of the glass substrate 110 corresponding to the camera and the infrared sensor of the display device to prevent the predetermined area 102 from being roughened.

[0048] In the embodiment of the present application, the glass substrate 110 is artificially divided into a patterned area 101 and a preset area 102 to facilitate explanation of the process performed on the two parts, but it should not be understood as a limitation on the glass substrate 110 .

[0049] Exemplarily, the protection portion 130 is disposed in the predetermined region 102 corresponding to the glass substrate 110 to prevent the predetermined region 102 from being roughened.

[0050] The protective portion 130 is disposed in the predetermined region 102 of the glass substrate 110 by printing. For example, a printing screen 120 is disposed on the glass substrate 110, and the printing screen 120 is provided with through holes 122 corresponding to the predetermined region 102 of the glass substrate 110, so as to facilitate the leakage of the protective material from the through holes 122 into the predetermined region 102. It is understood that, compared to other preparation methods, the use of the printing screen 120 can simplify the positioning of the predetermined region 102. The printing screen 120 can be directly disposed in correspondence with the entire glass substrate 110, and the through holes 122 are provided at the positions of the printing screen 120 corresponding to the predetermined region 102. The through holes 122 can be positioned relative to the predetermined region 102 of the glass substrate 110 by simply aligning the printing screen 120 with the glass substrate 110.

[0051] 202. Print a protective material from a printing screen and print it onto a predetermined area of ​​the glass substrate through the through hole to form a protective portion in the predetermined area.

[0052] The protective material is printed on the printing screen 120, that is, the protective material is printed on the predetermined area 102 of the glass substrate 110 through the through hole 122 of the printing screen 120. The thickness of the printing screen 120 can be consistent with the thickness of the protective portion 130 to be set. When the through hole 122 is filled with the protective material and then cured, the printing screen 120 can be removed to obtain the protective portion 130 formed in the predetermined area 102.

[0053] The protective material can be acid-resistant and light-shielding. The light-shielding material protects the predetermined region 102 during yellow light exposure, preventing patterning of the predetermined region 102 and thereby ensuring that the predetermined region 102 maintains a flat shape. The acid-resistant material is required because etching with an etchant, which is generally acidic, is required to remove the photoresist 140 later. This allows for the protection of the predetermined region 102 during different process steps.

[0054] For example, the protective material is acid-resistant ink. Of course, the protective material is not limited to acid-resistant ink, which is only illustrated here and should not be understood as a limitation on the type of protective material.

[0055] 203. A photoresist is provided on the glass substrate to cover the protective portion, and the side of the photoresist facing away from the glass substrate is a flat surface.

[0056] The present embodiment of the present invention uses the yellow light process or yellow light process as an example to illustrate the roughening treatment of the glass substrate 110, and should not be construed as limiting the type of photolithography process used for roughening the glass substrate. The yellow light process is a photolithography process in which a photosensitive material (also known as photoresist) coated on the glass surface is exposed and developed, and the remaining portion protects the underlying layer. The film is then etched and removed to ultimately obtain a permanent pattern.

[0057] Therefore, it is necessary to coat the glass substrate 110 with a photoresist 140 so as to facilitate patterning or roughening of the glass substrate 110 in subsequent processes.

[0058] Because the protective portion 130 is provided on the predetermined area 102 of the glass substrate 110, the photoresist 140 covers the protective portion 130, facilitating the installation of the photoresist 140 without requiring any avoidance of the protective portion 130. After the photoresist 140 is installed, the side of the photoresist 140 facing away from the glass substrate 110 is a flat surface. Consequently, when yellow light is applied from above the mask 150, the photoresist can be uniformly developed, eliminating the need for concerns about uneven development caused by uneven thickness.

[0059] 204. A mask plate is arranged above the photoresist, wherein the mask plate has a plurality of light-transmitting holes, and the plurality of light-transmitting holes are evenly arranged.

[0060] Accordingly, for the yellow light process, a mask 150 needs to be set and exposed to expose a specific pattern on the photoresist 140. This allows the patterned area 101 of the glass substrate 110 to be roughened when the photoresist 140 is removed, resulting in a concave-convex surface on the patterned area 101 of the glass substrate 110. The concave-convex surface can be understood as a rough and uneven surface. The rough and uneven surface can cause light to be diffusely reflected rather than specularly reflected, thereby achieving an anti-glare and soft light eye protection effect.

[0061] For example, a mask 150 is disposed above the photoresist 140, such as directly above it. The mask 150 has a plurality of light-transmitting holes 152. The plurality of light-transmitting holes 152 are evenly arranged, for example, in a multi-row and multi-column array, and are evenly distributed throughout the mask 150. The plurality of light-transmitting holes 152 have the same size. For example, the plurality of light-transmitting holes 152 can all be circular holes of the same size. For another example, the plurality of light-transmitting holes 152 can all be square holes of the same size. Of course, the light-transmitting holes 152 can also have other shapes, which are not listed here.

[0062] It should be noted that in the related art, in addition to light-transmitting holes, air-avoidance holes are provided on the mask plate corresponding to the functional components of each display device, such as cameras and infrared sensors. The air-avoidance holes are provided for functional components such as cameras and infrared sensors. The glass substrate corresponding to the air-avoidance holes does not need to be made into a concave or convex shape to avoid affecting the functional performance of the functional components. For different display devices, the location of functional components such as cameras or infrared sensors varies. Therefore, a mask plate needs to be developed for the anti-glare glass of each display device, which increases development costs.

[0063] Therefore, the embodiment of the present application separates the avoidance positions corresponding to the camera and infrared sensor from the mask plate 150. The mask plate 150 has evenly arranged light-transmitting holes 152, and the avoidance holes are eliminated. Therefore, different display devices can share the same mask plate 150, thereby improving the versatility of the mask plate 150 and reducing development costs.

[0064] 205. Light source is exposed from above the mask to develop the photoresist.

[0065] The light source, i.e., yellow light, is exposed from above the mask plate 150, and the yellow light is irradiated onto the photoresist 140 through the light-transmitting hole 152, thereby developing the photoresist 140, i.e., forming a specific pattern, for example, the photoresist 140 is formed with multiple evenly arranged through holes, or the photoresist 140 includes many columns.

[0066] 206. Etch the photoresist using an etching solution to form a concave-convex surface in the patterned area.

[0067] The photoresist 140 is then removed, for example, by etching away the photoresist 140 using an etching solution. Since the etching solution also has a certain impact on the glass substrate 110 , the patterned area 101 of the glass substrate 110 can be formed into a concave-convex surface, that is, the roughening of the patterned area 101 is completed.

[0068] The etching solution includes an acidic etching solution, for example, an acid solution containing fluoride ions can be used for etching.

[0069] It should be noted that since the predetermined area 102 is protected by the protection portion 130 and the material of the protection portion 130 is acid-resistant and light-shielding, the etching solution cannot etch the protection portion 130 , thereby protecting the predetermined area 102 thereunder.

[0070] 207. Remove the protective portion to form a flat surface in the predetermined area to form anti-glare glass.

[0071] The glass substrate 110 with the protective portion 130 can then be cleaned, and finally the protective portion 130 can be peeled off. Since the preset area 102 is shielded by the protective portion 130 , the preset area 102 can form a flat surface, thereby forming the anti-glare glass 100 .

[0072] In the method for preparing anti-glare glass provided in the embodiment of the present application, the existing mask plate is designed to include a avoidance position for the functional parts of the corresponding product, and is replaced by a protective portion 130 that is independent of the mask plate 150 and is provided in the preset area 102 corresponding to the glass substrate 110. There is no need to design a mask plate 150 for each product, that is, different products can share the mask plate 150, which improves the versatility of the mask plate 150 and can reduce development costs.

[0073] Please refer to Figures 4 and 5. Figure 4 is a schematic diagram of the third process of the method for preparing anti-glare glass provided in an embodiment of the present application, and Figure 5 is a schematic diagram of the second process of the method for preparing anti-glare glass provided in an embodiment of the present application. The second setting method is to set the protective portion on one side of the mask plate. The embodiment of the present application also provides a method for preparing anti-glare glass, including:

[0074] 301. Provide a glass substrate, wherein the glass substrate has a patterned area and a preset area, and the patterned area surrounds the preset area.

[0075] Since the mask plates in the related art cannot be shared, or have poor versatility, in order to improve the versatility of the mask plate 150 and thus reduce development costs, the embodiment of the present application separates the avoidance space originally made on the mask plate and makes it into a protective portion 130. As a result, different display devices can share the mask plate 150 when manufacturing the anti-glare glass 100.

[0076] Exemplarily, a glass substrate 110 is first provided, and both opposite sides of the glass substrate 110 are flat surfaces. The glass substrate 110 has a patterned area 101 and a preset area 102. The patterned area 101 is to process the surface of the glass substrate 110 so that the surface of the glass substrate 110 corresponding to the patterned area 101 becomes rough, and changes from mirror reflection to diffuse reflection, creating a clear and transparent visual effect. The glass substrate 110 is not processed in the preset area 102, so that the surface of the glass substrate 110 in the preset area 102 is flat or approximately flat, reducing the impact on the functional components of the display device. Among them, the patterned area 101 can be set around the preset area 102. For example, the preset area 102 corresponds to the camera or infrared sensor of the display device. If the camera and the infrared sensor are roughened at the glass substrate 110, the accuracy of the data collected by the camera and the infrared sensor will be affected. Therefore, in the embodiment of the present application, a protection portion 130 is disposed in the predetermined area 102 of the glass substrate 110 corresponding to the camera and the infrared sensor of the display device to prevent the predetermined area 102 from being roughened.

[0077] 302. Dispose a photoresist on a glass substrate.

[0078] The present embodiment of the present invention uses the yellow light process or yellow light process as an example to illustrate the roughening treatment of the glass substrate 110, and should not be construed as limiting the type of photolithography process used for roughening the glass substrate. The yellow light process is a photolithography process in which a photosensitive material (also known as photoresist) coated on the glass surface is exposed and developed, and the remaining portion protects the underlying layer. The film is then etched and removed to ultimately obtain a permanent pattern.

[0079] Therefore, it is necessary to coat the glass substrate 110 with a photoresist 140 so as to facilitate patterning or roughening of the glass substrate 110 in subsequent processes.

[0080] 303. A mask plate is arranged above the photoresist, wherein the mask plate has a plurality of light-transmitting holes, and the plurality of light-transmitting holes are evenly arranged.

[0081] Accordingly, for the yellow light process, a mask 150 needs to be set and exposed to expose a specific pattern on the photoresist 140. This allows the patterned area 101 of the glass substrate 110 to be roughened when the photoresist 140 is removed, resulting in a concave-convex surface on the patterned area 101 of the glass substrate 110. The concave-convex surface can be understood as a rough and uneven surface. The rough and uneven surface can cause light to be diffusely reflected rather than specularly reflected, thereby achieving an anti-glare and soft light eye protection effect.

[0082] For example, a mask 150 is disposed above the photoresist 140, such as directly above it. The mask 150 has a plurality of light-transmitting holes 152. The plurality of light-transmitting holes 152 are evenly arranged, for example, in a multi-row and multi-column array, and are evenly distributed throughout the mask 150. The plurality of light-transmitting holes 152 have the same size. For example, the plurality of light-transmitting holes 152 can all be circular holes of the same size. For another example, the plurality of light-transmitting holes 152 can all be square holes of the same size. Of course, the light-transmitting holes 152 can also have other shapes, which are not listed here.

[0083] It should be noted that in the related art, in addition to light-transmitting holes, air-avoidance holes are provided on the mask plate corresponding to the functional components of each display device, such as cameras and infrared sensors. The air-avoidance holes are provided for functional components such as cameras and infrared sensors. The glass substrate corresponding to the air-avoidance holes does not need to be made into a concave or convex shape to avoid affecting the functional performance of the functional components. For different display devices, the location of functional components such as cameras or infrared sensors varies. Therefore, a mask plate needs to be developed for the anti-glare glass of each display device, which increases development costs.

[0084] Therefore, the embodiment of the present application separates the avoidance positions corresponding to the camera and infrared sensor from the mask plate 150. The mask plate 150 has evenly arranged light-transmitting holes 152, and the avoidance holes are eliminated. Therefore, different display devices can share the same mask plate 150, thereby improving the versatility of the mask plate 150 and reducing development costs.

[0085] 304 . Dispose a protection portion on a side of the mask plate facing away from or toward the glass substrate and corresponding to a preset area of ​​the glass substrate.

[0086] The protective portion 130 is not limited to being disposed on the glass substrate 110 as described above. For example, the protective portion 130 may also be disposed on the mask plate 150. For example, the protective portion 130 may be disposed on a side of the mask plate 150 facing away from or toward the glass substrate 110, and the protective portion 130 may be disposed at a position corresponding to the predetermined area 102 of the glass substrate 110 to prevent the yellow light source from exposing the predetermined area 102.

[0087] The process for preparing the protective portion 130 is as follows: a printing screen 120 is placed on one side of a mask plate 150. The printing screen 120 can be the same size as the mask plate 150, and the printing screen 120 has through holes 122 corresponding to the predetermined areas 102 of the glass substrate 110. A protective material is printed or coated on the printing screen 120 and then printed onto the mask plate 150 through the through holes 122, forming the protective portion 130 corresponding to the predetermined areas 102 of the glass substrate 110.

[0088] The thickness of the printed screen 120 can be consistent with the thickness of the protective portion 130 to be set, so that when the protective material fills the through hole 122 and then solidifies, the printed screen 120 can be removed to obtain the protective portion 130 formed on the mask plate 150.

[0089] Exemplarily, the protective material is a light-shielding material. In this case, the protective portion 130 only needs to shield the preset area 102 of the glass substrate 110 to prevent exposure from affecting the preset area 102. Therefore, the protective material can be a light-shielding material, such as ink, or of course other materials, which will not be listed one by one here.

[0090] It should be noted that when making the protective part 130, since the light-transmitting holes 152 are evenly arranged on the mask plate 150, the protective material will inevitably fill part of the light-transmitting holes 152. In order to avoid difficulty in removing the protective material in the light-transmitting holes 152 later, a shielding layer (not shown in the figure) can be set on the mask plate 150 in the preset area 102 corresponding to the glass substrate 110 to prevent the protective material from falling into the light-transmitting holes 152.

[0091] 305. A light source is exposed from above the mask plate to develop the photoresist and form a concave-convex surface in the patterned area and a flat surface in the preset area to form an anti-glare glass.

[0092] Yellow light is applied from above the mask 150. The yellow light passes through the light-transmitting holes 152 and strikes the photoresist 140, thereby developing the photoresist 140 and forming a specific pattern. The photoresist 140 in the predetermined area 102 remains undeveloped due to the presence of the protective portion 130. The photoresist 140 on the glass substrate 110 is then removed, leaving the patterned area 101 of the glass substrate 110 with a concave-convex surface and the predetermined area 102 with a flat or nearly flat surface, thus forming the anti-glare glass 100.

[0093] In the method for preparing anti-glare glass provided in the embodiment of the present application, the existing mask plate is designed to include a avoidance position for the functional parts of the corresponding product, and is replaced by a protective portion 130 that is independent of the mask plate 150 and is provided in the preset area 102 corresponding to the glass substrate 110. There is no need to design a mask plate 150 for each product, that is, different products can share the mask plate 150, which improves the versatility of the mask plate 150 and can reduce development costs.

[0094] Please refer to Figure 6, which is a schematic diagram of the structure of the anti-glare glass provided in an embodiment of the present application. The embodiment of the present application also provides an anti-glare glass 100, which is prepared by the above-mentioned preparation method. The anti-glare glass 100 has a preset area 102 and a patterned area 101. The preset area 102 has a flat surface or a nearly flat surface to accommodate functional parts of the display device such as cameras and infrared sensors to collect data. The patterned area 101 is arranged around the preset area 102, and the area of ​​the patterned area 101 is larger than the area of ​​the preset area 102. The patterned area 101 has a concave-convex surface, so that the display part of the display device can present a clear visual effect when it passes through the patterned area 101, thereby enhancing the user experience.

[0095] Please refer to Figure 7, which is a schematic diagram of the structure of the display device provided in an embodiment of the present application. The above-mentioned anti-glare glass 100 is used in the display device 1, and the display device 1 can be a computer, tablet, mobile phone, TV, or other device that can display images. Among them, a tablet is also called a tablet computer, especially a tablet computer used by children, which has a higher demand for eye protection. Therefore, it is more common for such display devices to use soft light eye protection technology. The anti-glare glass 100 can be used as a cover plate of the display device 1, that is, it is set on the display screen 200 to protect the display screen 200, and can adjust the display effect of the display device 1.

[0096] In the anti-glare glass 100, its preparation method and display device 1 provided in the embodiment of the present application, by changing the existing mask plate designed to include a avoidance position for the functional parts of the corresponding product to a protective portion 130 that is independent of the mask plate 150 and corresponding to the preset area 102 of the glass substrate 110, there is no need to design a mask plate 150 for each product, that is, different products can share the mask plate 150, thereby improving the versatility of the mask plate 150 and reducing development costs.
