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

Embodiment Construction

[0025] The present invention is further illustrated by the following examples: According to the following examples, the present invention can be better understood. However, those skilled in the art can easily understand that the specific material ratios, process conditions and results described in the examples are only used to illustrate the present invention, and should not and will not limit the present invention described in the claims.

[0026] combine figure 1 As shown, the glass bead curtain surface includes a substrate 1, a transfer black layer 2 forming one side of the substrate 1, and a matt white layer 3 formed on the other side of the substrate 1, and the matt white layer 3 is embedded with microbeads 4. The microbeads 4 protrude from the surface of the matt white layer 3. The microbeads 4 include first microbeads with a first refractive index and second microbeads with a second refractive index. The first refractive index and the second refractive index are The tw...

Abstract

The invention discloses a projection screen. The projection screen comprises a substrate, a transfer black layer formed on one side of the substrate, and a matte white layer formed on the other side of the substrate, wherein micro-beads are embedded in the matte white layer; the micro-beads protrude out of the surface of the matte white layer; and the substrate comprises glass fibers, a polyvinylchloride matte white curtain and a surface embossing, which are overlapped in sequence. The curtain has good effects on gain, vision and sound attenuation.

Description

technical field [0001] The present application relates to a projection screen. Background technique [0002] The screen is produced with the development and needs of film technology and projection technology. The earliest known screen is the big screen of the cinema. With the improvement of projection technology and the popularization of projectors in education and engineering homes, the screen is becoming more The more people are familiar with. Projection screens have gone through an early stage of ordinary screens that only need to reflect images, and have gradually developed into screens that pursue high-level requirements such as perfect lifelike images, super-large screens, higher resolution, higher contrast, and better visual protection. [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 diffus...
