Abstract

A projection curtain comprises a substrate layer, a light shielding layer for shielding light, a reflective layer for reflecting light rays, and a particle layer for increasing the brightness of outgoing light rays; a particle layer, a reflective layer, a substrate layer and a light shielding layer are stacked in turn, wherein the particle layer comprises a particle matrix and a plurality of nanoparticles distributed in the particle matrix. The projection curtain provided by the invention has nanometer particles in the particle layer, and the outgoing light rays are refracted through the spherical structure of the nanometer particles, so that the brightness of the outgoing light rays is improved, and the incoming light rays are diffused to a certain extent, so that the incoming light raysare atomized, the small-angle incoming light rays are concentrated on the front surface to be emitted to ensure a wide viewing angle, and the halo phenomenon can be reduced at the same time.

Description

technical field [0001] The invention belongs to the technical field of projection display, and more specifically relates to a projection screen. Background technique [0002] Projection screens are used in conjunction with projectors to display images and videos in cinemas, office areas, home theaters, large conferences, and other occasions. Currently commonly used curtains can be divided into white curtains, gray curtains, metal curtains, etc. according to the color, and can be divided into traditional white curtains, soft curtains, glass fiber curtains, and sound-permeable curtains according to the material. Users can choose different screens according to the needs of different occasions. Types of curtains. For example, when the use environment of the curtain is good, the most traditional white curtain can meet the use requirements. [0003] White screens and gray screens are commonly used in medium and long-focus scenes, and they are cost-effective. However, the project...
