A preparation method of high-gain laser anti-light screen that can avoid moiré fringes

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 ...
