Title:
OPTICAL SHEET, MOLD, AND ELECTRONIC DEVICE COVER PLATE
Document Type and Number:
WIPO Patent Application WO/2018/210221
Kind Code:
A1
Abstract:
Disclosed is an optical sheet, comprising: a polymer layer; and multiple small stubs, which are disposed at one side of the polymer layer, forming a micro-nano structure layer, wherein at least one of the multiple small stubs is a protruded or recessed structure and has two edges parallel with each other or intersecting with each other in the plane. The present invention provides a novel texture structure, which can change directions of the small stubs freely or according to a desired effect in a certain direction, wherein an angle between the small stubs and the horizontal direction varies from 0° to 180°. Regarding an optical sheet having this texture structure, the optical sheet using this texture at least has one light beam under a particular light source, and the influence of rainbow mura on the lighting effect can be reduced to some extent. An electronic device cover plate using this texture structure or optical sheet can flexibly utilize the rotation angle of the small stubs to achieve different lighting effects of the electronic device cover plate.
