Description

Anti-glare glass, display module, electronic device and method for preparing anti-glare glass Technical Field

[0001] The embodiments of the present application relate to the technical field of anti-glare glass, and in particular to an anti-glare glass, a display module, an electronic device, and a method for preparing the anti-glare glass. Background Art

[0002] With the development of modern display technology, people have higher and higher requirements for the imaging of display screens, and the demand for user comfort has also begun to gradually increase. During the use of display screens, glare often occurs due to the influence of the surrounding environment. Glare refers to a visual condition. When there is an inappropriate brightness distribution in the field of view or an extreme brightness contrast in the space, the light entering the human eye will be scattered, which will not only seriously affect the visual experience, but also make people feel uncomfortable, disgusted, or even lose their vision. Anti-glare glass, referred to as AG glass, is a glass with a special surface treatment. Its principle is to process high-quality glass on one or both sides to make it have a lower reflectance than ordinary glass, thereby reducing the interference of ambient light, improving the clarity of the picture, reducing screen reflections, making the image clearer and more realistic, and allowing viewers to enjoy better visual effects.

[0003] Existing anti-glare glass is etched with regular concave and convex points on the surface. When used as cover glass for display screens, this solves the glare problem caused by reflection. However, since the pixels displayed on the display screen are also regular patterns, the overlap of two regular patterns will cause moiré patterns visually, causing dizziness and affecting the visual experience.

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0031] Anti-glare glass, also known as non-reflective or anti-reflective glass, is a glass surface treated on one or both sides to achieve a diffuse reflection effect at multiple angles. When used as a display screen cover, anti-glare glass can improve the viewing angle, reduce ambient light intrusion, and minimize screen glare.

[0032] Traditional anti-glare glass is produced by chemically etching the surface, creating irregularly shaped bumps and depressions of varying sizes and heights, thereby achieving diffuse reflection. However, due to the highly irregular nature of the bumps and depressions, the size of the resulting anti-glare glass cannot be precisely controlled. When used as a display screen cover, light from the display's pixels passing through these irregular bumps and depressions can easily cause flashes, affecting the visual quality of the display.

[0033] To prevent flash points, conventional methods involve etching regularly shaped concave and convex dots on the glass surface. This prevents flash points when used as a display screen cover. However, since the pixels on a display screen are regularly distributed, the concave and convex dots on the glass surface are also regularly distributed. When these two regularly distributed patterns overlap, they visually produce moiré patterns, which also affect the visual quality of the display. Moiré, also known as interference fringes, refers to the regular interference effect caused by two or more overlapping objects. When light passes through an object's surface, slight variations in the light's wavelength and the object's surface create intersecting ripples, known as moiré patterns. When glass with regularly shaped concave and convex points etched on the surface is used as a display cover, moiré patterns will occur. For example, when playing a video, the pixels corresponding to the image displayed during playback are regularly distributed, and each pixel is equivalent to a light point. The concave and convex points formed by etching on the glass surface of the display cover are also regularly distributed. Therefore, when the regularly distributed pixels (light points) overlap with the regularly distributed concave and convex points, an interference effect will be generated, thereby generating interference fringes. These interference fringes look like water ripples to the human eye. This visual phenomenon is called moiré.

[0034] When glass with regularly shaped concave and convex dots etched on the surface is used as a display cover, in order to reduce the moiré phenomenon, the viewing angle of the display can be adjusted to reduce the impact of the moiré. However, this method will cause a lot of inconvenience to the user during use and affect the user experience.

[0035] The embodiment of the present application arranges the first areas evenly at preset intervals on the surface of the glass body of the anti-glare glass, and the diagonal length of the shape of the first areas passing through the center point is the same as the diagonal length of the pixel points of the corresponding display screen. When the anti-glare glass is used as a cover for the display screen, the diffuse reflection phenomenon can be reduced, the anti-glare effect can be achieved, and the visual experience can be improved. In addition, by randomly distributing noise areas on the surface of the glass body and controlling the total area of ​​the noise areas to be 0.1% to 1% of the total area of ​​the glass body, the shape of the noise areas is circular or the shape of the noise areas is a regular polygon different from the shape of the first areas, which destroys the regular distribution of the first areas to a certain extent. When the anti-glare glass is used as a cover for the display screen, the moiré phenomenon caused by the interaction between the regularly distributed first areas and the regular pixel points of the display screen is avoided, thereby improving the anti-glare effect and enhancing the visual experience. Compared to traditional anti-glare glass, which is typically etched with regular concave and convex dots on its surface, when used as cover glass for display screens, while this solves the glare problem caused by reflections, because the pixels displayed on the display screen are also regularly distributed, the overlap of two regularly distributed patterns can cause a visual moiré phenomenon, resulting in a feeling of dizziness and a poor visual experience. Based on this, the anti-glare glass of the present application is provided to address the poor anti-glare effect of existing anti-glare glass.

[0036] FIG1 is a first schematic diagram of an anti-glare glass provided by an embodiment of the present application. Referring to FIG1 , the anti-glare glass comprises a glass body, the surface of which includes a plurality of first regions 10. The first regions 10 are regularly shaped. The shapes of the first regions 10 can be regular polygons, such as squares, rhombuses, regular hexagons, or regular octagons. FIG1 uses a square as an example for illustration. On the surface of the glass body, the first regions 10 are evenly spaced at predetermined intervals in a first direction and a second direction, wherein the first and second directions are perpendicular to each other. For example, as shown in FIG1 , the first and second directions are perpendicular to each other, and the first regions 10 are evenly spaced at predetermined intervals in both the first and second directions. The diagonal length of the shape of the first regions passing through their center points is the same as the diagonal length of the corresponding pixels on the display screen. By evenly arranging the first regions 10 at predetermined intervals in the first and second directions, and ensuring that the diagonal length of the shape of the first regions passing through their center points is the same as the diagonal length of the corresponding pixels on the display screen, the anti-glare glass can reduce diffuse reflection when used as a cover plate for a display screen, thereby providing an anti-glare effect and enhancing the visual experience.

[0037] In one embodiment, the length of the preset intervals is the same as the length of the shape of the first region 10. In one exemplary embodiment, when the shape of the first region 10 is a square, the length of the square is the length of the side of the square. When the shape of the first region 10 is a regular polygon such as a rhombus, a regular hexagon, or a regular octagon, the length of the regular polygon is its maximum width in the first direction. By setting the length of the preset intervals to be the same as the length of the shape of the first region 10, the first regions 10 are distributed more evenly and regularly on the surface of the glass body, thereby improving the anti-glare effect.

[0038] Based on the uniform distribution of the first regions 10 on the surface of the glass body, this embodiment also includes randomly distributed noise regions 20 on the surface of the glass body to prevent the appearance of moiré patterns when the anti-glare glass is used as a display cover. The size of the noise regions 20 is within a predetermined first range, and the total area of ​​the noise regions 20 is within a predetermined second range. This allows the noise regions 20 to disrupt the regular distribution of the first regions 10 while maintaining the anti-glare effect of the regular distribution of the first regions 10.

[0039] On the surface of the glass body, the first region 10 and the noise region 20 form a composite region. The area outside the composite region on the glass body surface is a second region 30. The composite region and the second region have different surface heights, resulting in a cross-section showing the composite region and the second region 30 at different heights, creating two relatively concave and convex regions. The composite region's surface height can be higher than the second region's 30, in which case the composite region is convex relative to the second region and the second region 30 is concave relative to the composite region; or the composite region's surface height can be lower than the second region's 30, in which case the composite region is concave relative to the second region and the second region 30 is convex relative to the composite region. By randomly distributing the noise regions 20 on the glass body surface and controlling the total area of ​​the noise regions to 0.1% to 1% of the total area of ​​the glass body, the regular distribution of the first region 10 is somewhat disrupted. In the absence of noise region 20, the remaining area outside first region 10 actually has a regular distribution due to the regular distribution of first region 10. However, the random distribution of noise region 20 also diversifies the outlines of the small area units in second region 30, thereby disrupting the regular distribution of second region 30. When this anti-glare glass is used on a display screen, it avoids the moiré phenomenon caused by the interaction between the regularly distributed first region 10 and the regularly distributed pixels of the display screen, thereby improving the anti-glare effect and enhancing the visual experience.

[0040] In one embodiment, the surface heights of the integrated region (i.e., the region composed of the first region 10 and the noise region 20) and the second region 30 are different, which can be achieved by etching. During etching, the corresponding integrated region and second region 30 are obtained by arranging the protective shape of the mask, so that the corresponding integrated region and second region 30 exist on the surface of the glass body after etching.

[0041] In one embodiment, the first region 10 and the noise region 20 have the same surface height. It should be noted that the same surface height here means that the surface heights are substantially the same, that is, the surface height difference and the two surface heights within a preset error range are considered to be the same.

[0042] The first region 10 is a regularly shaped region. The shape of the first region 10 can be a regular polygon, such as a square, rhombus, regular hexagon, or regular octagon. To enhance the anti-glare effect, the size of the first region 10 should be within a predetermined third range. The length of the diagonal line passing through the center point of the shape of the first region 10 is the same as the length of the diagonal line passing through the center point of the pixel points on the display screen. This ensures that the area of ​​the first region 10 is approximately the same as the area of ​​the corresponding pixel points on the display screen, thereby achieving a good anti-glare effect.

[0043] In one embodiment, the first area 10 is square in shape, and the size of the square is the same as the size of the corresponding pixel of the display screen. By setting the first area 10 to be square in shape and the same size as the corresponding pixel, that is, the side length of the square is the same as the side length of the corresponding pixel, a good anti-glare effect can be achieved. It should be noted that the pixel in this embodiment is square in shape.

[0044] It should be noted that, when the shape of the pixel is a rectangle, the same size can be understood as the side length of the square (the shape of the first area 10 ) being the same as the length or width of the pixel.

[0045] In one embodiment, the shape of the noise region 20 is circular or a regular polygon that is different from the shape of the first region 10. For example, assuming that the shape of the first region 10 is square, the shape of the noise region 20 is circular or other non-square regular polygon, such as a regular hexagon or a regular octagon. It should be noted that in order to improve the anti-glare effect, the noise regions 20 are regions of the same shape, for example, the shape of the noise regions 20 is circular. Multiple noise regions 20 are randomly distributed on the surface of the glass body, the size of each noise region 20 is within a preset first range, and the total area of ​​all noise regions 20 is within a preset second range. The preset first range can be understood as a maximum threshold for the area of ​​each noise region 20. When the area of ​​each noise region 20 exceeds this maximum threshold, the regularity of the distribution of the first region 10 is affected, thereby affecting the anti-glare effect of the first region 10 based on the regular distribution. Therefore, it is necessary to control the size (i.e., area) of each noise region 20 within the preset first range to ensure that the anti-glare effect of the first region 10 based on the regular distribution is not affected. The preset second range can be understood as a maximum threshold for the total area of ​​all noise regions 20. When the total area of ​​all noise regions 20 exceeds this maximum threshold, the regularity of the distribution of the first regions 10 will be affected, thereby affecting the anti-glare effect of the first regions 10 based on the regular distribution. Therefore, it is necessary to control the total area of ​​all noise regions 20 within the preset second range to ensure that the anti-glare effect of the first regions 10 based on the regular distribution is not affected.

[0046] In one embodiment, the diameter or the length of the diagonal line passing through the center point of each noise region 20 on the surface of the glass body is the same as the length of the diagonal line passing through the center of the shape of the first region 10, so that the size of each noise region 20 is within a predetermined first range. This ensures that each noise region 20 is approximately the same size as each first region 10. This prevents the randomly distributed noise regions 20 on the surface of the glass body from being too large, thereby avoiding affecting the regular distribution of the first regions 10 and, in other words, preventing the noise regions 20 from affecting the anti-glare function of the first regions 10. Furthermore, the addition of the randomly distributed noise regions 20 disrupts the regular distribution of the first regions 10 to a certain extent, thereby preventing the occurrence of moiré patterns generated by the interaction between the anti-glare glass and the pixels of the display screen during display, thereby improving the anti-glare effect.

[0047] For example, when the noise region 20 is circular, the diameter of each noise region 20 on the surface of the glass body is equal to the length of a diagonal line passing through the center of the first region 10, so that the size of each noise region 20 is within the preset first range. When the noise region 20 is a regular polygon different from the first region 10, the length of a diagonal line passing through the center of each noise region 20 on the surface of the glass body is equal to the length of a diagonal line passing through the center of the first region 10, so that the size of each noise region 20 is within the preset first range.

[0048] Figure 2 is a second schematic diagram of an anti-glare glass provided in an embodiment of the present application. This embodiment is described by taking the first area 10 as a regular octagon as an example. The first areas 10 are evenly arranged in the first and second directions according to preset intervals. The gray regular octagon in the figure is the first area 10, and the length of the preset interval is the length of the blank regular octagon, that is, the interval length of the preset interval is the same as the length of the shape of the first area 10. The length of the shape of the first area 10 can be understood as the maximum width of the first area 10 in the first direction, such as the length a in Figure 2. It should be noted that the length of the preset interval can be understood as the minimum distance between two adjacent first areas in the first direction, for example, the length b in Figure 2 is the length of the preset interval. The gray circle is the noise area 20. Figure 3 is a third schematic diagram of an anti-glare glass provided in an embodiment of the present application. Referring to Figure 3, the first area 10 and the noise area 20 are combined into a comprehensive area. In Figure 3, all gray areas are comprehensive areas. The second area 30 is the area other than the comprehensive area, that is, in Figure 3, the blank area is the second area 30.

[0049] In one embodiment, the total area of ​​the randomly distributed noise regions 20 on the surface of the glass body is 0.1% to 1% of the total area of ​​the glass body. By controlling the total area of ​​the noise regions 20 to 0.1% to 1% of the total area of ​​the glass body, the distribution of the noise regions 20 does not affect the anti-glare effect of the regularly distributed first regions 10. At the same time, the arrangement of the noise regions 20 can reduce the moiré pattern generated by the interaction between the anti-glare glass and the pixels of the display screen during display, thereby improving the anti-glare effect.

[0050] In one embodiment, as can be seen from the above, the surface height of the integrated area of ​​the surface of the glass body is different from the surface height of the second area, and the difference in surface height between the two can be achieved by etching. During etching, the etching depth needs to be well controlled to obtain a glass body with a suitable degree of roughness. Therefore, the surface height of the etched glass body can be calculated and processed to obtain the arithmetic mean deviation of the contour of the glass body. The arithmetic mean deviation of the contour can be understood as the arithmetic mean of the absolute value of the contour deviation within the sampling length. The etching process can be used to control the arithmetic mean deviation of the contour of the etched glass body to be within a certain range. In this embodiment, a glass body including an integrated area and a second area with different surface heights is obtained by etching, and the arithmetic mean deviation of the contour of the glass body is 0.1 to 0.6 μm. The width of the contour unit can be understood as the distance between each etching position, and the average width of the contour unit can be understood as the average value of the distance between each etching position. Since the glass body in this embodiment is obtained by etching, the average width of the contour unit of the etched glass body can be controlled by controlling the distance between each etching position during etching. Therefore, by calculating the size of the first area, the noise area or the second area in the etched glass body, the average width of the contour unit corresponding to the glass body can be obtained. In this embodiment, a glass body including a comprehensive area and a second area with different surface heights is obtained by etching, and the average width of the contour unit of the glass body is less than 60um. The haze of the glass body is 20% to 40%, the transmittance is more than 90%, and the reflectivity is less than 7%. By controlling the arithmetic mean deviation of the contour to 0.1 to 0.6um and the average width of the contour unit to less than 60um, the glass body has a certain roughness, which improves the touch experience. In addition, by controlling the haze to 20% to 40%, the transmittance to more than 90%, and the reflectivity to less than 7%, a good display effect can be achieved, and combined with the distribution setting of the comprehensive area and the second area on the surface of the aforementioned glass body, when the anti-glare glass is used as a cover plate for a display screen, it can achieve a good display function while avoiding flash points and glare phenomena, and at the same time avoiding the occurrence of moiré patterns, thereby improving the anti-glare effect and thus improving the user's visual experience.

[0051] In one embodiment, FIG4 is a fourth schematic diagram of an anti-glare glass provided in an embodiment of the present application. Referring to FIG4 , in addition to the aforementioned glass body 1, the anti-glare glass further includes an anti-reflection film 2 to enhance display quality. The anti-reflection film 2 covers the surface of the glass body 1. Furthermore, in addition to the aforementioned glass body 1, the anti-glare glass further includes a high-transmittance anti-fingerprint film 3. The high-transmittance anti-fingerprint film 3 covers the surface of the glass body 1 or the anti-reflection film 2 to provide an anti-fingerprint effect.

[0052] As described above, by evenly arranging the first areas at preset intervals on the surface of the glass body of the anti-glare glass, and the diagonal length of the shape of the first areas passing through the center point is the same as the diagonal length of the pixel points of the corresponding display screen, when the anti-glare glass is used as a cover for the display screen, the diffuse reflection phenomenon can be reduced, the anti-glare effect can be achieved, and the visual experience can be improved; in addition, by randomly distributing the noise areas on the surface of the glass body and controlling the total area of ​​the noise areas to be 0.1% to 1% of the total area of ​​the glass body, the shape of the noise areas is circular or the shape of the noise areas is a regular polygon different from the shape of the first areas, which destroys the regular distribution of the first areas to a certain extent. When the anti-glare glass is used as a cover for the display screen, the moiré phenomenon caused by the interaction between the regularly distributed first areas and the regularly distributed pixel points of the display screen is avoided, thereby improving the anti-glare effect and further improving the visual experience.

[0053] An embodiment of the present application further provides a display module comprising the above-mentioned anti-glare glass.

[0054] An embodiment of the present application further provides an electronic device, comprising the above-mentioned anti-glare glass or the above-mentioned display module.

[0055] FIG5 is a flow chart of a method for preparing anti-glare glass provided in an embodiment of the present application. The method for preparing anti-glare glass provided in this embodiment can be performed by an anti-glare glass preparation device. The anti-glare glass preparation device can be implemented via software and / or hardware. The anti-glare glass preparation device can be composed of two or more physical entities, or a single physical entity. Generally speaking, the anti-glare glass preparation device can be an etching device, such as an etching control device.

[0056] The following description will be made by taking the etching control device as the main body of the anti-glare glass preparation method as an example. Referring to FIG5 , the anti-glare glass preparation method is configured to prepare the above-mentioned anti-glare glass, specifically comprising:

[0057] S101. Obtain a glass substrate, attach a layer of photoresist to the surface of the glass substrate, and make a protective pattern on the photoresist to obtain a first substrate, wherein the protective pattern includes a first protective pattern and a second protective pattern, the first protective pattern is evenly arranged in a first direction and a second direction according to a preset interval, the first direction and the second direction are perpendicular to each other, and the diagonal length of the first protective pattern passing through the center point is the same as the diagonal length of the pixel point of the corresponding display screen; the second protective pattern is randomly distributed, and the total area of ​​the second protective pattern is 0.1% to 1% of the total area of ​​the glass substrate; the second protective pattern is a circle, or the second protective pattern is a regular polygon different from the first protective pattern.

[0058] A layer of photoresist is applied to the surface of the obtained substrate, and a protective pattern is formed on the photoresist to obtain a first substrate. The protective pattern includes a first protective pattern and a second protective pattern. The first and second protective patterns are also called mask patterns. The first protective pattern is a regular pattern, such as a regular polygon such as a square, a regular hexagon, or a regular octagon. The diagonal length of the first protective pattern passing through the center point is the same as the diagonal length of the corresponding pixel on the display screen. The second protective pattern is a circle or other regular polygon different from the first protective pattern. For example, when the first pattern is a square, the second protective pattern can be a circle or other regular polygon other than a square, such as a regular hexagon or a regular octagon. It should be noted that the first protective pattern corresponds to the aforementioned first area, and the second protective pattern corresponds to the aforementioned noise area. The second protective pattern is randomly distributed, with the size of the second protective pattern within a preset first range and the total area of ​​the second protective pattern within a preset second range. The preset second range is that the total area of ​​the second protective pattern is 0.1% to 1% of the total area of ​​the glass substrate. The first protective pattern is evenly arranged along the first direction and the second direction on the photoresist at preset intervals, and the first direction and the second direction are perpendicular to each other. The second protective pattern is randomly distributed, the size of the second protective pattern is within the preset first range, and the total area of ​​the second protective pattern is within the preset second range. As described above, by evenly arranging the first protective pattern in the first direction and the second direction at preset intervals, a regular first area (such as a raised area) is present after etching. Based on the effect of the regular first area on the glass body, when the anti-glare glass is configured as a display cover for display, the phenomenon of diffuse reflection can be reduced, playing an anti-glare role and improving the visual experience.

[0059] In one embodiment, the length of the preset intervals is the same as the length of the first protective pattern. By setting the length of the preset intervals to be the same as the length of the shape of the first protective pattern, the first protective pattern on the photoresist (i.e., the glass substrate) is distributed more evenly and regularly, thereby improving the anti-glare effect of the anti-glare glass obtained by etching.

[0060] In one embodiment, to enhance the anti-glare effect, the size of the first protective pattern should be within a predetermined third range. The length of a diagonal line passing through the center point of the first protective pattern is the same as the length of a diagonal line passing through the center point of a corresponding pixel on the display screen. This ensures that the size of the first protective pattern is approximately the same as the size of the corresponding pixel on the display screen, thereby achieving a good anti-glare effect.

[0061] In one embodiment, the second protective pattern can be a circle or other regular polygon that is different from the first protective pattern. In order to control the size of the second protective pattern within a preset first range, the second protective pattern can be set so that its diameter or the length of the diagonal passing through the center point is the same as the length of the diagonal passing through the center of the shape of the first area, so that the size of the second protective pattern is within the preset first range, thereby making the second protective pattern almost the same size as the first protective pattern, and thus making the randomly distributed second protective pattern not too large in size, thereby avoiding affecting the regular distribution of the first protective pattern.

[0062] For example, when the second protective pattern is circular, the diameter of the second protective pattern is equal to the length of a diagonal line passing through the center of the first protective pattern, so that the size of each second protective pattern is within the preset first range. When the second protective pattern is a regular polygon different from the first protective pattern, the length of a diagonal line passing through the center of the second protective pattern is equal to the length of a diagonal line passing through the center of the first protective pattern, so that the size of each second protective pattern is within the preset first range.

[0063] It should be noted that after etching, the areas on the surface of the glass body corresponding to the first protection pattern and the second protection pattern are raised.

[0064] S102 , performing exposure and development processing on the first substrate to obtain a second substrate.

[0065] The first substrate having the first protective pattern and the second protective pattern obtained above is first subjected to preliminary soft baking and curing, then sequentially exposed and developed, and then subjected to secondary hard baking and curing to obtain a second substrate.

[0066] S103 , performing etching and demolding processing on the second substrate to obtain a third substrate.

[0067] The second substrate obtained above is subjected to acid etching treatment, and then the residual photoresist on the surface of the substrate after the acid etching treatment is stripped off by a physical wiping method to obtain a third substrate.

[0068] S104 , performing liquid polishing on the third substrate to obtain anti-glare glass.

[0069] The third substrate obtained above is subjected to liquid polishing treatment to obtain the corresponding anti-glare glass. The surface of the glass body of the prepared anti-glare glass includes a plurality of first areas (corresponding to the first protective pattern), and the first areas are evenly arranged in the first direction and the second direction according to the preset intervals, and the first direction and the second direction are perpendicular to each other. The diagonal length of the shape of the first area passing through the center point is the same as the diagonal length of the pixel point of the corresponding display screen. Noise areas (corresponding to the second protective pattern) are randomly distributed on the surface of the glass body, and the total area of ​​the noise area is 0.1% to 1% of the total area of ​​the glass body; the shape of the noise area is circular, or the shape of the noise area is a regular polygon that is different from the shape of the first area. The first area and the noise area constitute a comprehensive area, and the surface height of the comprehensive area is different from the surface height of the second area. The second area is the area on the surface of the glass body excluding the comprehensive area. The comprehensive area obtained by the above preparation method is convex relative to the second area, and the second area is concave relative to the comprehensive area.

[0070] FIG6 is a flow chart of another anti-glare glass manufacturing method provided in an embodiment of the present application. The anti-glare glass manufacturing method provided in this embodiment can be performed by an anti-glare glass manufacturing device. The anti-glare glass manufacturing device can be implemented through software and / or hardware. The anti-glare glass manufacturing device can be composed of two or more physical entities, or a single physical entity. Generally speaking, the anti-glare glass manufacturing device can be an etching device, such as an etching control device.

[0071] The following description will be made by taking the etching control device as an example of the main body of the anti-glare glass preparation method. Referring to FIG6 , the anti-glare glass preparation method is configured to prepare the above-mentioned anti-glare glass, specifically comprising:

[0072] S201. Obtain a glass substrate, attach a layer of photoresist to the surface of the glass substrate, and make a protective pattern on the photoresist to obtain a first sub-substrate, wherein the protective pattern includes a first protective pattern, and the first protective pattern is evenly arranged in a first direction and a second direction according to a preset interval, the first direction and the second direction are perpendicular to each other, and the diagonal length of the first protective pattern passing through the center point is the same as the diagonal length of the pixel point of the corresponding display screen.

[0073] A layer of photoresist is attached to the surface of the obtained substrate, and a protective pattern is made on the photoresist to obtain a first sub-substrate. The protective pattern includes a first protective pattern, and the diagonal length of the first protective pattern passing through the center point is the same as the diagonal length of the pixel point of the corresponding display screen. The first protective pattern is also called a mask pattern. The first protective pattern is a regular pattern, such as a regular polygon such as a square, a regular hexagon or a regular octagon. The first protective pattern is evenly arranged at preset intervals along the first direction and the second direction on the photoresist, and the first direction and the second direction are perpendicular to each other. As described above, the first protective pattern is evenly arranged at preset intervals in the first direction and the second direction, so that a regular first area (such as a raised area) exists after etching. Based on the effect of the regular first area on the glass body, when the anti-glare glass is configured as a display cover for display, the phenomenon of diffuse reflection can be reduced, thereby playing an anti-glare role and improving the visual experience.

[0074] In one embodiment, the length of the preset intervals is the same as the length of the first protective pattern. By setting the length of the preset intervals to be the same as the length of the shape of the first protective pattern, the first protective pattern on the photoresist (i.e., the glass substrate) is distributed more evenly and regularly, thereby improving the anti-glare effect of the anti-glare glass obtained by etching.

[0075] In one embodiment, to enhance the anti-glare effect, the size of the first protective pattern should be within a predetermined third range. The length of a diagonal line passing through the center point of the first protective pattern is the same as the length of a diagonal line passing through the center point of a corresponding pixel on the display screen. This ensures that the size of the first protective pattern is approximately the same as the size of the corresponding pixel on the display screen, thereby achieving a good anti-glare effect.

[0076] S202. Hollow out the first protection pattern on the first sub-substrate according to the noise area to obtain a first substrate, wherein the noise area is randomly distributed, and the total area of ​​the noise area is 0.1% to 1% of the total area of ​​the glass substrate; the shape of the noise area is a circle, or the shape of the noise area is a regular polygon different from the first protection pattern.

[0077] To improve the anti-glare effect, the first protective pattern on the first sub-substrate is hollowed out according to the noise area to obtain the first substrate. The noise area is randomly distributed, the size of the noise area is within a preset first range, and the total area of ​​the noise area is 0.1% to 1% of the total area of ​​the glass substrate. It should be noted that the hollowed-out area should be the area where the first protective pattern and the noise area overlap, that is, the first protective pattern is retained without overlapping the noise area. By hollowing out the first protective pattern according to the noise area, the noise area in the etched anti-glare glass is recessed.

[0078] In one embodiment, the shape of the noise area can be a circle or other regular polygon that is different from the first protection pattern. In order to control the size of the noise area within a preset first range, the shape of the noise area can be set to have its diameter or the length of the diagonal passing through the center point be the same as the length of the diagonal passing through the center of the shape of the first area, so that the size of the noise area is within the preset first range, thereby making the shape of the noise area similar to the size of the first protection pattern, and further ensuring that the shape of the randomly distributed noise area is not too large, thereby avoiding affecting the regular distribution of the first protection pattern.

[0079] For example, when the noise region is circular, the diameter of the noise region is equal to the length of a diagonal line passing through the center of the first protection pattern, so that the size of each noise region is within a preset first range. When the noise region is a regular polygon different from the first protection pattern, the length of a diagonal line passing through the center of the noise region is equal to the length of a diagonal line passing through the center of the first protection pattern, so that the size of each noise region is within the preset first range.

[0080] S203 , performing exposure and development processing on the first substrate to obtain a second substrate.

[0081] The first substrate having the first protective pattern and the second protective pattern obtained above is first subjected to preliminary soft baking and curing, then sequentially exposed and developed, and then subjected to secondary hard baking and curing to obtain a second substrate.

[0082] S204 , performing an etching and demolding process on the second substrate to obtain a third substrate.

[0083] The second substrate obtained above is subjected to acid etching treatment, and then the residual photoresist on the surface of the substrate after the acid etching treatment is stripped off by a physical wiping method to obtain a third substrate.

[0084] S205 , performing liquid polishing on the third substrate to obtain anti-glare glass.

[0085] The third substrate obtained above is subjected to liquid polishing treatment to obtain the corresponding anti-glare glass. The surface of the glass body of the prepared anti-glare glass includes a plurality of first areas, and the first areas are evenly arranged in the first direction and the second direction according to the preset intervals, and the first direction and the second direction are perpendicular to each other. Noise areas are randomly distributed on the surface of the glass body, and the size of the noise area is within the preset first range. The total area of ​​the noise area is 0.1% to 1% of the total area of ​​the glass body; the shape of the noise area is circular or the shape of the noise area is a regular polygon that is different from the shape of the first area. The first area and the noise area constitute a comprehensive area, and the surface height of the comprehensive area is different from the surface height of the second area. The second area (the area corresponding to all the first protective patterns after the hollowing out treatment) is the area on the surface of the glass body excluding the comprehensive area. The comprehensive area obtained by the above preparation method is concave relative to the second area, and the second area is convex relative to the comprehensive area.

[0086] As mentioned above, the surface height of the integrated area obtained after etching is different from the surface height of the second area. When the anti-glare glass is used as a display screen cover, it can match the pixel size of the display screen, thereby avoiding the occurrence of flash points. At the same time, due to the existence of the noise area, the overall pattern on the glass body is irregular, which can avoid the formation of moiré patterns between the regular display screen pixels, thereby improving the visual experience.

[0087] As described above, by evenly arranging the first areas at preset intervals on the surface of the glass body of the anti-glare glass, and the diagonal length of the shape of the first areas passing through the center point is the same as the diagonal length of the pixel points of the corresponding display screen, when the anti-glare glass is used as a cover for the display screen, the diffuse reflection phenomenon can be reduced, the anti-glare effect can be achieved, and the visual experience can be improved; in addition, by randomly distributing the noise areas on the surface of the glass body and controlling the total area of ​​the noise areas to be 0.1% to 1% of the total area of ​​the glass body, the shape of the noise areas is circular or the shape of the noise areas is a regular polygon different from the shape of the first areas, which destroys the regular distribution of the first areas to a certain extent. When the anti-glare glass is used as a cover for the display screen, the moiré phenomenon caused by the interaction between the regularly distributed first areas and the regularly distributed pixel points of the display screen is avoided, thereby improving the anti-glare effect and further improving the visual experience.
