Title:
SCRATCH-RESISTANT ANTI-REFLECTION GLASS, DISPLAY SCREEN OF ELECTRONIC DEVICE, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/202163
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application is a scratch-resistant anti-reflection glass product, comprising: a glass substrate; an optical coating, which is superimposed on at least one surface of the glass substrate and comprises anti-reflection film layers, wherein the anti-reflection film layers are formed by means of alternately superimposing high-refractive-index layers and low-refractive-index layers. The optical coating further comprises a first scratch-resistant layer and a second scratch-resistant layer, wherein the first scratch-resistant layer and the second scratch-resistant layer are separately superimposed between the anti-reflection film layers or on surfaces of anti-reflection films; and the first scratch-resistant layer and the second scratch-resistant layer are not adjacent to each other. Further provided in the embodiments of the present application are a display screen of an electronic device, and an electronic device. According to the embodiments of the present application, a first scratch-resistant layer and a second scratch-resistant layer are arranged between anti-reflection film layers in a superimposed manner, and the second scratch-resistant layer serves as a buffer layer to provide a buffer function for the first scratch-resistant layer, such that a short, thick and hard scratch cannot be formed on a product. Therefore, the product can maintain a good appearance and a good impact resistance capability when serving as a display screen of an electronic device.
