Problems solved by technology

However, when the moth-eye microstructure is processed on the surface of a hard glass cover, the processing is difficult due to the hardness of the glass cover. Selecting a relatively small size cannot ensure that the microstructure has a large aspect ratio, which will lead to poor microstructure processing effect

Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] Since the preparation of moth-eye structures on the surface of glass substrates (such as convex cone-shaped anti-reflection microstructures with gradient refractive index) can achieve better anti-reflection effects, moth-eye structures are usually prepared on the cover plate to reduce the reflectivity of the surface of mobile phones . Such as figure 1 As shown, in the preparation method of the existing cover plate, specifically include the steps: first provide a glass substrate (such as figure 1 shown in a), followed by preparing a layer of transparent silicone soft film layer with the same or similar refractive index as the glass on the surface of the cleaned glass substrate (such as figure 1 shown in b), and then spin-coat a layer of nanoimprint adhesiv...

Abstract

The invention provides a preparation method of a cover plate. The preparation method comprises the steps: providing a glass substrate; and forming an etching mask formed from metal particles on at least one of the upper and lower surfaces of the glass substrate, and etching the surface, formed with the etching mask, of the glass substrate to form a convex conical antireflection microstructure witha gradually-varied refractive index on the corresponding etched surface of the glass substrate. By applying the preparation method, an imprinting rubber material in a traditional nanometer imprintingprocess is replaced with metal ions, so that the etching selection ratio in an imprinting and etching process is increased, the microstructure is guaranteed to have a relatively large depth-to-widthratio, and it is realized that a moth-eye microstructure is processed on the surface of a glass cover plate with higher hardness.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for preparing a cover plate and the cover plate. Background technique [0002] People are often troubled by ambient light when using mobile phones. Strong ambient light will not only reduce the contrast of the mobile phone, but also affect the chromaticity of the panel display, causing great troubles for people's reading. Anti-reflective coating is usually applied on the surface of the cover plate to reduce the reflectivity of the surface of the mobile phone, which has become a common means for people. [0003] However, the cost of anti-reflective coating is relatively high, and the design and processing technology of the film system are relatively complicated. For this reason, an effective anti-reflection effect can also be achieved by preparing a moth-eye-like microstructure on the surface of the cover plate. However, when the moth-eye microstructure is processed on...
