[0002] At present, when sunlight or light irradiates on the glass, the light reflected into the eyes of people is relatively strong due to the mirror reflection, which can cause a slight dizziness phenomenon, which is called "glare". The anti-glare glass is a special glass which can realize a good anti-glare effect by processing some convex points or groove microstructures on the surface of the glass to convert the reflection mode of the glass surface from mirror reflection to diffuse reflection. The anti-glare glass is often used as a cover glass in electronic products and is widely applied after being attached with a display screen. However, the anti-glare glass commonly used in the industry is made by frosting method, which has a good anti-glare effect, but the groove microstructures on the surface of the glass made by the frosting method are arranged in disorder, and the particle size and depth consistency is poor. In actual application, when the display screen is used as a cover glass by being matched with the anti-glare glass through optical glue or frame glue, the groove microstructures can cause the brightness of the display screen to be uneven, and many small flickering phenomena (referred to as "sparkle" in the industry) can be observed when visually observed, which results in a poor actual picture display clarity and affects the display effect and the visual experience of the user.

At least one of the length, width and diagonal of the glass-based product is greater than or equal to 500mm. The bending difference between the first bending value before etching the first surface and the second surface and the second bending value after etching the first surface and the second surface is less than or equal to 0.15mm, across each of one or more 500mm intervals of the length, width or diagonal of the glass-based product.

DETAILED DESCRIPTION
[0031] The specific embodiments of the present application and the shapes, structures, mutual positions and connection relationships between the parts, the functions and working principles of the parts, etc. involved in the description of the embodiments will be further described in detail below with reference to the drawings:
[0032] As shown in the drawings Figure 1 - the drawings Figure 6 The present application is an anti-glare glass, which comprises a glass substrate 1, a glass microstructure surface 2 is arranged on the surface of the glass substrate 1, the glass microstructure surface 2 comprises a plurality of groove parts 3, a groove gap part 4 is arranged between adjacent groove parts 3, and each groove part 3 comprises a slot opening 3-1, a slot side wall 3-2 and a slot bottom surface 3-3. The above structure improves the technical solution in view of the deficiencies in the prior art. The traditional anti-glare glass in the industry has no slot bottom surface and gap part on the groove of the glass microstructure surface, and the size and depth of the groove are uncontrollable, which results in low clarity and serious flash point when the anti-glare glass is used with a display screen, affecting the display effect. The anti-glare glass described in the present application mainly relies on the slot side wall 3-2 of the groove part 3 of the glass microstructure surface 2 for optical diffuse reflection to achieve the purpose of anti-glare, relies on the slot bottom surface 3-3, the groove gap part 4 and the size setting to control the clarity, and relies on the structure and size setting of the slot opening 3-1, the slot side wall 3-2 and the slot bottom surface 3-3 and the setting angle and angle range between the surface of the glass microstructure surface 2 to control the flash point, which effectively improves the clarity when the anti-glare glass is used with a display screen, reduces the flash point, improves the display effect and the visual experience of the user. The anti-glare glass described in the present application has a simple structure and can effectively solve the problems of uneven brightness, flickering phenomenon and poor clarity of the display screen, thereby forming a low-flash-point and high-definition display screen. The improvement point of the anti-glare glass of the present application mainly lies in improving the specific structure of the glass microstructure surface 2, which involves the shapes of the groove part 3 and the groove gap part 4, the sizes and size ratios of the related parts, etc. The structure is refined from different angles, thereby effectively improving the anti-glare performance of the glass. The slot opening 3-1 of the groove part 3 has a regular annular or irregular annular structure in plan view. The above structure, the glass microstructure surface 2 comprises a plurality of groove parts 3, a groove gap part 4 is arranged between adjacent groove parts 3, and the groove part 3 (i.e. located in the Figure 1 , the drawings Figure 2The groove part 3 includes a groove opening 3-1, a groove side wall 3-2, and a groove bottom surface 3-3. The top view of the groove part 3 is regular or irregular annular, wherein the outer contour of the annular is the top view contour of the groove opening, and the inner contour of the annular is the top view contour of the groove bottom surface. The shape of the groove opening 3-1 in the top view is circular or polygonal or irregular, and the size of the groove opening 3-1 needs to be within a certain range. Because the shape of the groove opening 3-1 is not specifically limited, for convenience of description, the size of the groove opening 3-1 is quantitatively represented by area, and the area of the groove opening needs to be between 4πum 2 -10000πum 2 to prevent and display the moire and serious flash point of the pixel of the display screen. The anti-glare glass described in the application has simple structure and can effectively solve the problems of uneven brightness, flicker phenomenon, and poor definition of the display screen, thereby forming a product with low flash point and high definition.
[0033] The top view structure of the groove bottom surface 3-3 of the groove part 3 is circular or polygonal or irregular. The top view contour of the groove bottom surface 3-3 can be circular or polygonal or irregular, which is not specifically limited. The size of the groove bottom surface 3-3 needs to be within a certain range. Because the shape of the groove bottom surface 3-1 is not specifically limited, for convenience of description, the size of the groove bottom surface is quantitatively represented by area, and the top view area of the groove bottom surface needs to be between 1πum 2 -400πum 2 and must be smaller than the top view area of the groove opening, so as to ensure high definition and anti-glare effect.
[0034] The top view structure area of the groove opening 3-1 of the groove part 3 is between 4πum 2 -10000πum 2 The top view structure area of the groove bottom surface 3-3 of the groove part 3 is between 1πum 2 -400πum 2 The above structure limits the respective size ranges of the top view structure of the groove opening 3-1 and the top view structure of the groove bottom surface 3-3 of the groove part 3, ensures that the area of the groove bottom surface 3-3 is smaller than the top view area of the groove opening 3-1, improves performance, and ensures high definition and anti-glare effect.
[0035] The area of all groove gap parts 4 on the glass microstructure surface 2 of the glass substrate 1 + the area of the groove bottom surface 3-3 is less than 40% of the entire area of the glass microstructure surface 2. The above structure limits the proportion of the sum of the areas of all groove gap parts and the groove bottom surface to the entire area of the glass microstructure surface 2, which can effectively ensure that the glass has sufficient anti-glare effect.
[0036] The glass substrate 1 is supported by soda or aluminum silicon or boron silicon, and the thickness of the glass substrate 1 is less than 5 mm. The above structure can ensure that the display screen product has high clarity when in use.

The above structure, the groove side wall 3-2 is a free curved surface, the included angle between the groove side wall 3-2 and the glass microstructure surface 2 is between 90-180 degrees (not including 90 degrees and 180 degrees), and the included angle between the groove side wall 3-2 and the groove bottom surface 3-3 is between 90-180 degrees (not including 90 degrees and 180 degrees). In this way, the specific structure of the glass is limited to ensure the anti-glare effect.
[0038] The included angle between the extension surface 3-4 of the groove bottom surface 3-3 of the groove part 3 and the glass microstructure surface 2 is greater than or equal to 0 degrees, and the included angle between the extension surface 3-4 of the groove bottom surface 3-3 of the groove part 3 and the glass microstructure surface 2 is less than or equal to 20 degrees. The above structure, the included angle between the extension surface of the groove bottom surface and the glass microstructure surface 2 is greater than or equal to 0 degrees and less than or equal to 20 degrees, which ensures that the glass has high clarity when in use.
[0039] The groove gap part 4 of the groove part 3 is the minimum distance between adjacent groove parts 3, and the size of the groove gap part 4 is within 150um (including 0um). The above structure, the groove gap 4 is the minimum distance between adjacent grooves, and the size of the groove gap part 4 needs to be within 30um (including 0um) to ensure that it has sufficient anti-glare effect. In the actual structure of the product, the larger the size of the groove gap part 4, the higher the clarity when used with the display screen.
[0040] The maximum height between the groove bottom surface 3-3 of the groove part 3 and the glass microstructure surface 2 is between 0.3um and 7um. The above structure, the maximum height between the groove bottom surface 3-3 and the glass microstructure surface 2 is between 0.3um and 7um, which is further shrunk within the range of 0.3um-7um according to the different anti-glare glass gloss and haze indexes required by the customer. To improve the performance, the structure can be further controlled to ensure that the structure has a good inhibitory effect on the "sparkle" phenomenon.
