Embodiment 1

[0032] An all-round anti-peeping film with anti-reflection function, its structure is as follows Figure 1-2 As shown, it includes a PET layer 140, a peep-proof structure layer arranged on one side surface of the PET layer 140, the peep-proof structure layer includes a resin bottom layer 120 and a UV photocurable resin layer 110, and a peep-proof structure layer arranged on the other side surface of the PET layer 140 Moth-eye AR structure layer 150 . Wherein the resin bottom layer 120 is also made of UV photocurable resin. The UV photocurable resin layer 110 is formed with a penetrating structure 130 that penetrates the upper and lower surfaces. In this embodiment, the penetrating structure 130 is a cylindrical cavity structure, and all cylindrical cavities are arranged in a rectangular array. The maximum diameter is 5-100 microns, the distance between two adjacent cavities is 5-100 microns, and the height of each cavity is 5-200 microns. In this embodiment, the cavity adopts...

Embodiment 2

[0035] An all-round anti-peeping film with anti-reflection function, its structure is as follows image 3 As shown, it is roughly the same as the embodiment 1, except that in this embodiment, the through structures 130 are distributed in the UV curable resin layer 110 in the form of a hexagonal array. The moth-eye anti-reflection structure layer is a cone arranged in an array, and the diameter of the bottom of the cone is less than one-half of the incident light wavelength. In this embodiment, the ratio of the depth of the cone to the bottom diameter is 0.5, and the distance between the center and the diameter of the bottom of the cone is 0.5. The ratio is 1.

Embodiment 3

[0037] An all-round anti-peeping film with anti-reflection function, its structure is as follows Figure 4 As shown, it is substantially the same as the embodiment 1, except that in this embodiment, the through structures 130 are distributed in the UV curable resin layer 110 in the form of a circular array. The moth-eye anti-reflection structure layer is a cone arranged in an array, and the diameter of the bottom of the cone is less than one-half of the incident light wavelength. In this embodiment, the ratio of the depth of the cone to the bottom diameter is 20, and the distance between the centers and the diameter of the bottom of the cone The ratio is 20.

Abstract

The invention relates to an omnibearing peep-proof film with an antireflection function and a manufacturing process thereof. The omnibearing peep-proof film comprises a PET layer, a peep-proof structural layer arranged on one side surface of the PET layer and a moth-eye antireflection structural layer arranged on the other side surface of the PET layer, wherein the peep-proof structural layer comprises a resin bottom layer and a UV light-cured resin layer; parameters can be changed according to the actual requirement, so that a visual angle can be freely selected, the security of a display screen in any direction is guaranteed, and the light transmittance in a visual range is high; by virtue of the bionics principle, the moth-eye antireflection structural layer adopts a moth-eye-like micro-nano structure as the antireflection layer, so that the loss of reflected light can be effectively inhibited in a relatively wide wave spectrum range; a reel-to-reel UV double-side rolling process comprises an adhesive dripping step, a filling step, a UV illuminating step and a demolding step, and different structures can be separately press-printed on two side surfaces of the PET layer, so that the manufacturing process is simple, and the commercialization requirement on rapidness, large area, high resolution and high flux can be met.

Description

technical field [0001] The invention belongs to the technical field of optical polarization, and in particular relates to an all-round anti-peeping film with an antireflection function and a manufacturing process thereof. Background technique [0002] The rapid development of electronic products has not only changed people's production and lifestyle, but also brought great convenience and fun to people's life. However, the problem of leakage caused during the use of electronic products has gradually attracted people's attention. Due to the large viewing angle of the screen of existing electronic products, for individuals, the security of personal privacy such as bank account numbers and passwords is not guaranteed. For enterprises, commercial secrets may also be peeped, and they face a great risk of leakage. . Therefore, an optical film is needed to reduce the risks of privacy leakage caused by the use of electronic products. [0003] At present, the anti-peeping films on...
