Title:
ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/185179
Kind Code:
A1
Abstract:
An anti-reflection glass, comprising: a glass substrate (1), a first surface of the glass substrate (1) having a micro-nano structure (11); and a first anti-reflection film layer (2) stacked on the first surface of the glass substrate (1), the first anti-reflection film layer (2) being formed by alternately superposing high-refractive-index layers (21) and low-refractive-index layers (22). Further disclosed are an electronic device display screen and an electronic device. The micro-nano structure (11) of a micron- or nano-sized surface structure is arranged on the surface of the glass substrate (1) to ensure the dense accumulation of atoms in a film layer at a short range and increase the hardness of the film layer, such that the scratch resistance of the surface of a film-coated glass. Meanwhile, an undulating structure at a long range enables the film layer stress to be released locally at a long range, reduces the stress deformation of the glass substrate, such that the glass substrate (1) is not subjected to large stress deformation when a thick anti-reflection film layer is stacked, and can be used in large-sized structures such as electronic device display screens.
