S-shaped light-resistant curtain and preparation method thereof

Abstract

The invention discloses an S-shaped light-resistant curtain and a preparation method thereof. The S-shaped light-resistant curtain comprises a base material layer and an optical prism array arranged on the outer surface of the base material layer; the optical prism array is a plurality of prisms which are closely arranged, are bent like an S-shaped wave in a horizontal direction and have triangular cross sections; the lower side surfaces of the prisms are coated with reflective coatings; and the upper side surfaces of the prisms are coated with light absorption coatings. The optical prism array on the surface of the S-shaped light-resistant curtain is arranged like the S-shaped wave in the horizontal direction; a horizontal symmetry relation between a curtain structure and a pixel spacingcan be changed; and as projection equipment, especially a curtain of a desktop type laser television, the aesthetic feeling of appearance can be improved, and optical interference phenomena such as Moire patterns and the like can be avoided, so that the uniformity of the reflection brightness is improved, the appearance flaws are not obvious, and the visual aesthetic feeling of customers in viewing is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of anti-light curtains, and in particular relates to an S-shaped anti-light curtain and a preparation method thereof. Background technique [0002] Patent US7262911B2 discloses a reflective screen (also known as an anti-light curtain) for reflecting imaging light projected from a projector at an angle relative to the viewer to a direction substantially perpendicular to the reflective screen, i.e. viewing the front of the person. The reflective screen includes a substrate having a sawtooth appearance, and a light absorbing layer on one edge of each sawtooth of the substrate. The basic structure of the existing reflective screen is roughly the same, that is, there is a sawtooth appearance on the surface of the substrate, and the sawtooth forms a linear and equidistant prism structure. However, the shape of the prism strip (sawtooth strip) of this prism structure is single, and the film is transparent. If the...

AI Technical Summary

Problems solved by technology

[0003] Therefore, in view of the technical problems in the prior art that the prism strips of the prism structure of the reflective screen have a single shape, moiré interference phenomenon is easily generated, and the visual effect is easily affected by appearance defects, the purpose of the present invention is to provide an S-shaped anti- Light curtain, the S-shaped anti-light curtain is optimized on the prism microstructure to avoid moiré interference, and the appearance defects will not be obvious. In addition to improving the uniformity, it also improves the visual beauty of customers viewing
