[0021] Please see Figures 1 to 5 This utility model provides three technical solutions:

[0022] Example 1: An anti-glare and privacy film, comprising a first substrate layer 1, a second substrate layer 11, and an anti-glare and privacy component;

[0023] A second substrate layer 11 is disposed below the first substrate layer 1, and both the first substrate layer 1 and the second substrate layer 11 are provided with anti-glare and anti-peeping components.

[0024] Example 2: Based on Example 1, the anti-glare and privacy component includes a first privacy structure layer 2 and a first privacy structure 3; the first privacy structure layer 2 is disposed on the upper surface of the first substrate layer 1, and a plurality of first privacy structures 3 are disposed in the first privacy structure layer 2. The top of the first privacy structure 3 is a prism or a plane or has an arc protrusion, and the height of the protrusion is 2-3 μm; this technical solution improves the light transmittance.

[0025] The angle between the sidewall of the first privacy structure 3 and the vertical plane of the substrate layer is 1° to 5°. That is, the angle between the sidewall of the privacy structure or prism structure and the substrate layer is 85° to 89°. Using this technical solution, the resulting privacy film has a better privacy effect of up to 26 degrees and high light transmittance.

[0026] The main material of the first privacy structure 3 is acrylic resin, polyurethane resin, or polyester resin; the resin of the first privacy structure 3 is a low refractive index resin with a refractive index of 1.48-1.50.

[0027] The upper surface of the first privacy structure 3 is provided with a black adhesive layer 4, and the graphite particles in the black adhesive layer 4 are PMMA or PBMA. This technical solution provides a better 180-degree privacy effect and high brightness. Furthermore, an anti-glare layer 5 is provided above the black adhesive layer 4, and multiple anti-glare structures 6 are provided on the anti-glare layer 5.

[0028] The anti-glare structure 6 is a concentric circle structure or a concentric hexagonal structure, with a concentric circle diameter of 1-3mm, a peak-valley depth of 20-25um, a peak-to-peak spacing of 80-90um, and a valley-to-valley spacing of 80-90um; the resin used has a refractive index of 1.50-1.55.

[0029] Implementation 3: Based on Embodiment 2, the lower surface of the first substrate layer 1 is provided with first connecting grooves 10 at equal intervals, and the first connecting grooves 10 are provided with second connecting grooves 11. The first connecting grooves 10 and the second connecting grooves 11 are used to position and connect the first substrate layer 1 and the adhesive layer 7.

[0030] The second connecting groove 11 is adapted to and connected to the second connecting block 9, and the first connecting groove 10 is adapted to and connected to the first connecting block 8, and the first connecting block 8 and the second connecting block 9 are disposed on the upper surface of the adhesive layer 7.

[0031] A second privacy structure 14 is provided below the adhesive layer 7, and a second privacy black adhesive 13 is provided in the second privacy structure 14, and a second substrate layer 12 is provided below the second privacy structure 14.

[0032] Preparation method: First, prepare a base film, PET or PC. Then, laser-engrave a stainless steel roller blank to create a micro-concave roller with an anti-spy structure, and then chrome-plat the surface to a 0.1µm chromium layer. Next, laser-engrave a stainless steel roller blank to create a micro-concave roller with an anti-glare structure 6, either 1. a concentric hexagonal structure or 2. a square pyramidal structure, and then chrome-plat the surface to a 0.1µm chromium layer. Then, apply the anti-spy acrylic coating to the upper surface of the base film 1 using a hard-press transfer method and cure it under ultraviolet light to obtain the first anti-spy structure 3. Then, apply black glue... Acrylic coating is applied to the surface of the privacy structure using a metal roller with an anti-glare structure and cured under ultraviolet light to obtain a privacy film. The curing method is carried out under ultraviolet light with a curing energy of 1000-1500 mj / cm2 to obtain a prism black adhesive structure layer. Then, under the first substrate layer 1, an adhesive is applied to the surface using a micro-concave oven coating process to a thickness of 10-20 μm. The second substrate layer 12 is coated in the same way as above. Finally, the upper and lower layers are bonded together to obtain this anti-glare multilayer privacy film, which can provide 360° privacy protection.

[0033] By utilizing the refractive index and thickness of the thin film to control the interference of reflected and transmitted light, when incident light is reflected from the AR film surface, the anti-glare structure design causes a phase difference in the reflected light, resulting in destructive interference between the reflected lights, thus greatly reducing the intensity of the reflected light. Simultaneously, the transmitted light is enhanced due to constructive interference, increasing light transmittance. The screen reflectivity is reduced from 4.5% to 1.5%, improving screen visibility. Even in bright outdoor environments, the screen content remains clearly visible, while reducing the stimulation of strong light reflection on the eyes, alleviating visual fatigue, and protecting the eyes. The privacy viewing angle is within 26 degrees, with good brightness and a glare value UGR < 12.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
