Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to an anti-glare glass and an electronic device. Background Technology

[0002] Anti-glare glass is a type of functional glass widely used in consumer electronics. Its anti-glare properties reduce specular reflection and scattering of ambient light on the display screen, resulting in a clearer display. Therefore, AG anti-glare glass is widely used in the displays of electronic devices such as automotive displays, laptops, tablets, smartphones, and televisions.

[0003] With the continuous development and popularization of the electronics market, the demand for anti-glare glass is also increasing. Traditional anti-glare glass has grooves of varying sizes on its surface. Although it basically has the function of anti-glare glass, the inconsistent size and depth of the grooves bring about technical problems related to flash point, especially the inability to achieve both high anti-glare effect and low flash point, which limits its widespread application. Although the technical solution disclosed in Chinese Patent No. CN220305509U, which has completely consistent groove shape and size, solves the above technical problems, the products of this solution still have moiré patterns at a certain viewing distance.

[0004] Solving these technical problems has become an urgent technical challenge for the industry. Summary of the Invention

[0005] In order to at least solve the above-mentioned technical problems, the purpose of this utility model is to provide an anti-glare glass that has high anti-glare performance while eliminating flash points and moiré patterns.

[0006] To achieve the above objectives, the anti-glare glass provided in this application includes:

[0007] At least one anti-glare surface;

[0008] The anti-glare surface has a groove array consisting of multiple parallel rows of grooves;

[0009] Each column of the groove array includes multiple grooves with different diameters, and adjacent grooves have the same center distance and share the same edge.

[0010] The diameter of the groove ranges from 20 to 150 μm;

[0011] The spacing between adjacent columns of the groove array is no greater than cos30° of the groove diameter.

[0012] Furthermore, the diameter difference of any groove within the groove array is 3-70 μm.

[0013] Furthermore, the diameter dimensions of the grooves within the groove array follow a normal or similar normal distribution with the average of the single maximum diameter dimension and the single minimum diameter dimension as the center value.

[0014] Furthermore, the diameter of the grooves in the groove array is divided into multiple equal parts with the maximum and minimum diameters as endpoints, and the number of grooves in each part accounts for the same proportion of the total number of grooves in the groove array.

[0015] Furthermore, the depth of the groove ranges from 0.3 to 25 μm.

[0016] Furthermore, the depth difference of any groove within the groove array is at most 0.5-15 μm.

[0017] Furthermore, the groove array also includes grooves of the same diameter.

[0018] Furthermore, the groove is U-shaped in the vertical direction.

[0019] Furthermore, the groove is polygonal in the horizontal direction.

[0020] To achieve the above objectives, this application also provides an electronic device, including: the aforementioned anti-glare glass.

[0021] The anti-glare glass of this utility model not only solves the conflict between high anti-glare effect and low flash point; while having excellent anti-glare effect, it also eliminates flash point and moiré patterns; thus enhancing the product's market competitiveness.

[0044] In one exemplary embodiment, the anti-glare surface is provided with a groove array consisting of multiple rows of parallel grooves.

[0045] In one exemplary embodiment, the groove is used because anti-glare glass typically achieves its anti-glare function by creating grooves through etching the surface of a glass substrate, thereby roughening the surface of the glass substrate.
