An ultra-short throw front projection screen

By pressing a prism with a triangular sawtooth texture structure into the inner side of the substrate of the anti-glare projection screen and coating it with a light-absorbing and reflective material, the problems of easy damage and poor absorption of parallel light in anti-glare projection screens are solved, resulting in better projection effects and a longer service life.

AI Technical Summary

Technical Problem

Existing black grid and Fresnel anti-glare projection screens are easily damaged at sharp points and have poor absorption of parallel light, affecting projection quality and lifespan.

Method used

The material is made of flexible and rollable substrate. The inner side is coated with a base layer and the prism body with a triangular sawtooth texture structure is pressed out by embossing roller. The light-absorbing and reflective surfaces of the prism body are printed with color, and the light-absorbing surface has an arc-shaped extension coated with light-absorbing material, while the reflective surface is coated with reflective material.

Benefits of technology

It improves the absorption of top and parallel light, reduces screen damage, extends lifespan, and enhances projection performance.

Abstract

The utility model discloses an ultra short focus orthographic projection screen, the anti-light projection screen includes the base material body of flexible coiling base material, the base material body inside is coated with base layer through the flow cast production, and the base layer is pressed out several strip texture structure's prism body through the embossing roller, and every prism body cross section is triangular sawtooth texture structure, and this triangular sawtooth texture structure includes the light reflection surface of oblique setting and the light absorption surface of horizontal setting, and the light absorption surface is equipped with extension, and the end of extension far from the light absorption surface is jointed with the light reflection surface. The extension of well-equipped can better absorb the light from the light of parallel light in the top and house, makes the projection effect better.
