Problems solved by technology

When the short-wave light emitted by the projector is close to the wavelength of ultraviolet light, defined as 10-400nm (nanometer), the ultraviolet light will diffusely reflect on the human body, causing harm to the human body.
[0003] Most of the base color of the traditional projection screen is white, and the 3D image reflected to the human eye is formed by integrating the misplaced projected image with the help of 3D glasses to form a three-dimensional effect. Not only is it inconvenient to wear glasses, but the imaging definition is low, and the color of the signal itself cannot be obtained The restoration, contrast and image depth of field are not enough, and cannot meet the standards of advertising media and other practical industries

Abstract

The invention relates to a nanoparticle coated film type transparent anti-ultraviolet projection screen and a production method thereof. The nanoparticle coated film type transparent anti-ultraviolet projection screen comprises a transparent support layer and a nanoparticle coated film layer uniformly coated on the surface of the transparent support layer. The nanoparticle coated film layer is made by the steps of uniformly mixing nanoparticles, dispersant and solvent, being dispersed by nanoparticle dispersion liquid, uniformly coating on the upper surface of the transparent support layer, drying and conducting heat treatment. The nanoparticle distribution density of the nanoparticle coated film layer is 0.005-0.05g / mm.m2. The production method includes the steps of preparing the nanoparticle dispersion liquid, plating a nanoparticle film, drying and heat treatment. Compared with the prior art, the production method is simpler, the production efficiency is high and the cost is low. The transparency and sharpness of the product are higher, 2.5D and 3D images can be displayed directly, and the imaging effect is good. No auxiliary equipment is required for viewing. The nanoparticle coated film type transparent anti-ultraviolet projection screen is more convenient to use. Nanoparticles absorb ultraviolet rays under light transmission conditions, thereby effectively preventing diffuse reflection of ultraviolet rays onto a human body.

Description

technical field [0001] The invention relates to the field of projection screen production, in particular to a transparent anti-ultraviolet projection screen and a production method thereof. Background technique [0002] Currently, overhead projectors and slide projectors are widely used as a way for speakers to display materials at conferences and the like, and among them, video projectors and movie projectors using liquid crystals are also widely used in ordinary homes. The projection method of these projectors involves modulating light output from a light source with a projection type liquid crystal surface or the like to form image light, and emitting the image light through an optical system such as a lens to be projected onto a screen. When the short-wave light emitted by the projector is close to the wavelength of ultraviolet light, defined as 10-400nm (nanometer), the ultraviolet light will diffusely reflect on the human body, thereby causing harm to the human body. ...
