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 preparation method of a high-gain laser anti-light screen capable of avoiding Moire fringes. 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 light diffusion Fresnel lens layer, and attaching the Fresnel lens layer to the contrast ratio film; (4) plating a metal reflecting layer on the Fresnel lens layer; (5) preparing a protective film, and laminating a protective film layer on the metal reflecting layer; (6) preparing an adhesive film, and attaching the adhesive film to the protective film layer; (7) enabling the honeycomb aluminum plate to be attached to the adhesive film. The gain of the screen is 1.2, the left and right visual angles are 25 degrees, the visual angle is 170 degrees, the contrast ratio is 20000: 1, the imaging scene depth sense is excellent, the display effect is clear, and Morie fringes are not generated.

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 ...
