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 the 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 manufacturing technology usually involves chemical etching or physical sandblasting followed by chemical polishing of the glass substrate surface. However, traditional anti-glare glass manufacturing technology has many drawbacks, such as high manufacturing cost, poor environmental friendliness, and difficulty in balancing anti-glare effect and flash point. In particular, when the glass has strong anti-glare performance, the flash point value of the glass surface is very high, which can easily cause eye fatigue for users. These factors limit its widespread application.

[0004] While Chinese patent CN116675439B solved the technical challenge of simultaneously achieving high anti-glare performance and low flash point, it still presents issues with moiré patterns and rainbow patterns. How to achieve both low flash point performance and resolve the moiré and rainbow pattern problems has become a pressing technical challenge for the industry. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology, the purpose of the utility model is to provide an anti-glare glass that, while having high anti-glare performance, also eliminates flash points, moiré patterns and rainbow patterns.

[0006] To achieve the above objectives, this application provides an anti-glare glass, comprising:

[0007] At least one anti-glare surface;

[0008] The anti-glare surface has an array of grooves arranged irregularly.

[0009] The diameter of any groove in the groove array is the same, the center distance between adjacent grooves is not exactly the same, and adjacent grooves share the same edge.

[0010] The diameter of the groove ranges from 15 to 150 μm, and the difference between the maximum and minimum diameter of the groove is 3 to 70 μm.

[0011] The grooves have the same depth.

[0012] The center-to-center distance between adjacent grooves is 15-120 μm.

[0013] Furthermore, the difference between the maximum and minimum center-to-center distance between adjacent grooves on the groove array is not less than 2 μm.

[0014] Furthermore, the difference between the maximum and minimum center-to-center distance between adjacent grooves on the groove array is not less than 2 μm and not greater than 20 μm.

[0015] Furthermore, the groove array also includes the following: the center distance between adjacent grooves is the same.

[0016] Furthermore, the center-to-center distance between adjacent grooves on the groove array follows a normal or similar normal distribution with the average of the single maximum center-to-center distance and the single minimum center-to-center distance as the center value.

[0017] Furthermore, the center-to-center distance between adjacent grooves on the groove array is divided into multiple equal parts with the maximum and minimum center-to-center distances as endpoints, and the number of center-to-center distances in each part accounts for the same proportion of the total number of center-to-center distances on the groove array.

[0018] Furthermore, the depth of the groove ranges from 0.3 to 25 μm.

[0019] Furthermore, the difference between the maximum and minimum diameter of the groove is 3-70 μm.

[0020] Furthermore, the groove is U-shaped in the vertical direction.

[0021] To achieve the above objectives, this application also provides an electronic device, including: the aforementioned anti-glare glass.

[0022] 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, moiré pattern and rainbow pattern; thus enhancing the product's market competitiveness.
