[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 preparation methods.
[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 amount of sanding agent and dispersing agent is 5% to 8% and 0.5% to 0.5% of the weight of UV hardening liquid, respectively. 1%. The sanding agent is a silica sanding agent with a particle size of 4-8 μm. As the dispersant, methyl amyl alcohol dispersant was used. Its preferred formula is: including UV hardening liquid, sanding agent, dispersant and black nano-color paste; wherein, the dosage of sand-finishing agent, dispersing agent and black nano-color paste is 5% to 8% of the weight of UV hardening liquid, respectively. 0.5% to 1%, 6% to 9%. The addition of black nano-color paste makes the surface color of the AG film layer to be transparent black. Black light absorption can improve the anti-interference light function of the scre...

Abstract
The invention discloses a method for preparing a high-gain laser anti-light screen based on a Fresnel lens, comprising steps: (1) preparing an AG film layer; (2) preparing a contrast film, and laminating the contrast film and the AG film; 3) Prepare a Fresnel lens; (4) Make a cylindrical mirror layer on the Fresnel lens layer by using a water coating transfer method; (5) Plating a metal reflective layer on the cylindrical mirror layer; (6) Prepare a protective (7) attaching a protective film layer on the metal reflective layer; (8) preparing an adhesive film and attaching it to the metal reflective layer; (9) attaching the honeycomb aluminum plate to the adhesive film. The screen display effect of the present invention is better, and has high gain, wide viewing angle and high contrast. The display effect of this screen with a commercially available laser machine of 2,000 yuan is equivalent to the effect of other screens with a laser machine of more than 20,000 yuan, which can save users 70% of the cost. At the same time, it brings huge development space to the laser screen market.
Description
technical field [0001] The invention belongs to the technical field of optical display, in particular 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 anti-light screen is not good. For example, (1) in the existing laser anti-light screen, the AG film layer is obtained by UV glue through the mold photo-curing and imprinting, resulting in dense crystal dots in the image during display. ; (2) The contrast film layer mixes the light diffusing agent with the color, resulting in an impure color and affecting the contrast; and the viewing angle is not large, and the light is scattered forward; (3) The surface of the Fresnel lens cannot be a cylindrical mirror , the gain of the laser anti-light screen is not high. SUMMARY OF THE INVENTION [0003] In order to solve the problems raised in the background art, the present invention provides a preparation method of a high-ga...
