Problems solved by technology

[0002] The display effect of the existing laser light-resistant screen is not good. For example, (1) in the existing laser light-resistant screen, the AG film layer is obtained by UV glue through mold photocuring and embossing, resulting in dense crystal points appearing in the image when displayed ;(2) The contrast film layer is to mix the light diffusing agent and the color together, resulting in impure color and affecting the contrast; and the viewing angle is not large, and the light is forward scattered; (3) The surface of the Fresnel lens cannot be a cylindrical mirror , causing the gain of the laser anti-light screen to be low

Embodiment

[0037] This example will provide the preparation method.

[0038] (1) Preparation of AG film layer:

[0039] In this embodiment, the formula of the AG film layer is: including UV hardening liquid, sanding agent and dispersing agent; wherein, the consumption of sanding agent and dispersing agent is respectively 5%~8%, 0.5%~of the weight of UV hardening liquid. 1%. The sand surface agent adopts a silica sand surface agent with a particle size of 4-8 μm. The dispersant is methyl amyl alcohol dispersant. Its preferred formula is: including UV hardening liquid, sand surface agent, dispersant and black nano color paste; wherein, the consumption of sand surface agent, dispersant, black nano color paste is respectively 5%~8% of the weight of UV hardening liquid, 0.5% to 1%, 6% to 9%. The addition of black nano-color paste makes the surface of the AG film layer transparent and black. Black light absorption can improve the anti-interference light function of the screen. Even in the ...

Abstract

The invention discloses a preparation method of a high-gain laser anti-light screen based on a Fresnel lens. The preparation method comprises the following steps: (1) preparing an AG film layer; (2) preparing a contrast film, and attaching the contrast film to the AG film; (3) preparing a Fresnel lens; (4) manufacturing a cylindrical mirror layer on the Fresnel lens layer by using a water coating transfer printing method; (5) plating a metal reflecting layer on the cylindrical mirror layer; (6) preparing a protective film; (7) laminating a protective film layer on the metal reflecting layer; (8) preparing an adhesive film and attaching the adhesive film to the metal reflecting layer; (9) enabling the honeycomb aluminum plate to be attached to the adhesive film. The invention has the advantages of better screen display effect, high gain, wide viewing angle and high contrast. The display effect of the screen matched with a commercially available 2000 yuan laser machine is equivalent to the effect of other screens matched with more than 20000 yuan laser machines, and 70% of cost can be saved for users. And meanwhile, huge development space is brought to the laser screen market.

Description

technical field [0001] The invention belongs to the technical field of optical display, and in particular relates to a preparation method of a high-gain laser anti-light screen based on a Fresnel lens. Background technique [0002] The display effect of the existing laser light-resistant screen is not good.
