High-brightness micro-bead projection screen

Abstract

The invention discloses a high-brightness micro-bead projection screen. The high-brightness micro-bead projection screen comprises a curtain base, a PVC black layer formed on one side of the curtain base, and a PVC white layer formed on the other side of the curtain base, wherein micro-beads are embedded in the PVC white layer; the micro-beads protrude out of the surface of the PVC white layer; and a white anti-halation agent layer covers the surfaces of the micro-beads. The projection screen of the scheme is suitable for screens of an outdoor automobile cinema and an outdoor mobile movie projection system; compared with a conventional outdoor matte white curtain, the brightness is at least improved by 80%, the gain reaches 1.8, and an outdoor active 3D system can be perfectly matched; enough brightness can be achieved by the projection screen, and the projection screen also can be used for controlling rainy and wind-blowing environments for outdoor use, so that an audience can enjoy an indoor movie hall watching effect with high contrast and high color rendition when watching the movie outdoors.

Description

Technical field [0001] This application relates to a projection equipment, in particular to a high-brightness bead projection screen. Background technique [0002] The screen is produced with the development and needs of film technology and projection technology. The first recognized screen is the big screen of the movie theater. With the improvement of projection technology, and the popularization of projectors in education and engineering homes, the screen is also more and more. The more familiar it is. Projection screens have gone from the early ordinary screens that can only reflect images, and have gradually developed into screens that pursue high-level requirements such as perfect lifelike images, super-large images, higher resolution, higher contrast, and better visual protection. [0003] Traditional screens use high-pressure air spraying to make the functional layer. This method will change with the instability of the air pressure. In addition, a considerable part of the ...

AI Technical Summary

Problems solved by technology

[0003] The traditional screen uses high-pressure air spraying to make the functional layer. This method will change with the instability of the air pressure. In addition, a considerable part of the paint will be lost with the diffusion of the air. The film is thin and needs to be processed many times. Meet specific film thickness requirements

[0004] In addition, the coating used in traditional curtains is difficult to meet the actual needs in terms of gain, visual angle and sound attenuation
