Embodiment

[0028] This example will provide the preparation method.

[0029] (1) Preparation of AG film layer:

[0030] 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 method for preparing a high-gain laser anti-light screen that can avoid moiré fringes, comprising: (1) preparing an AG film layer; (2) preparing a contrast film, and laminating the contrast film and the AG film; (3) Prepare the light-diffusing Fresnel lens layer, and bond the Fresnel lens layer and the contrast film; (4) coat the metal reflective layer on the Fresnel lens layer; (5) prepare a protective film, and bond the metal reflective layer A protective film layer; (6) preparing an adhesive film, and attaching the adhesive film to the protective film layer; (7) attaching the honeycomb aluminum plate to the adhesive film. The screen of the present invention has a gain of 1.2, a left and right viewing angle of 25 degrees, a visual viewing angle of 170 degrees, a contrast ratio of 20,000:1, excellent imaging depth, clear display effect, and no moiré.

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 which can avoid moiré fringes. Background technique [0002] Due to the limitations of the existing laser light-resistant screen preparation process, the existing laser light-resistant screen generally has poor imaging depth of field and inevitably produces moiré fringes. Contents of the invention [0003] The object of the present invention is to provide a method for preparing a high-gain laser anti-light screen that can avoid moiré fringes, improve imaging depth of field, and avoid moiré fringes. [0004] A preparation method of a high-gain laser anti-light screen capable of avoiding moiré fringes of the present invention comprises: [0005] (1) Prepare the AG film slurry, apply the AG film layer slurry on the surface of the PET optical pre-coating film, and then dry and ultraviolet light curing ...
