Title:
ANTIREFLECTION FILM, COVER PLATE STRUCTURE, AND MANUFACTURING METHOD FOR ANTIREFLECTION FILM
Document Type and Number:
WIPO Patent Application WO/2023/024544
Kind Code:
A1
Abstract:
The present application discloses an antireflection film, a cover plate structure, and a manufacturing method for an antireflection film. The antireflection film comprises one or more antireflection units; a plurality of antireflection units are sequentially stacked along a first direction, and the first direction is a light exit direction of the antireflection film; the one or more antireflection units comprise a first antireflection unit; the first antireflection unit comprise a first thin film layer and a second thin film layer; the second thin film layer and the first thin film layer are sequentially stacked along the first direction, and the surface of the first thin film layer distant from the second thin film layer is a light exit surface of the antireflection film; and the first thin film layer is of a porous structure, the porous structure is used for reducing the refractive index of the first thin film layer, and the refractive index of the first thin film layer is lower than the refractive index of the second thin film layer. The antireflection film has a better antireflection effect on incident light at different angles.
