Texture structure, optical thin film, mould and electronic device cover plate

Abstract

The present invention discloses a texture structure, an optical thin film, a mould and an electronic device cover plate. The texture structure comprises a plurality of distributed short lines, the plurality of short lines are arranged to be protruded and/or depressed, a gap is provided between adjacent short lines, and the gap forms an optical structure. The present invention provides a new texture structure, of which a direction of the short lines can be changed in a certain direction randomly or according to an expected effect, a side surface of the short line being an arc-shaped surface, adjacent arc-shaped surfaces connecting with each other to form a gap, and the gap being an optical structure, and provides an optical thin film having the texture structure, the optical thin film using this texture having at least one light beam under a certain light source and reducing to a certain extent the influence of rainbow streaks on light-shadow effects, and also provides an electronic device cover plate using the texture structure or the optical thin film, by which the rotational angles of the short lines can be used flexibly to realize different light-shadow effects of the electronic device cover plate.
