AI Technical Summary
The existing anti-peeping film requires an additional anti-peeping structural layer when making, which increases the cost and production process, and cannot effectively cover the edge of the curved screen, resulting in insufficient protection.
An anti-vigilance soft film design including an OCA layer, a PET substrate layer and a matte layer is adopted. One side of the PET substrate layer is coated with a matte layer, and a raised structure is provided on the other side. The outer wall of the raised structure is covered with light barrier material, and a bent portion curved to one side is provided along the extension to adapt to the shape of the curved screen.
The number of layers of the anti-peeping film is reduced, production costs and process complexity is reduced, and the curved screen is effectively covered, which enhances the protection of the mobile phone screen, and prevents fingerprint traces through a matte layer, which improves the touch texture.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field related to protective films for electronic equipment, in particular to an anti-peeping soft film. Background Art
[0002] With the development of science and technology, mobile phones and computer screens are gradually enlarged. It is inevitable to use electronic products in public places in daily life. Therefore, the content displayed on the screen can be easily seen by others. Therefore, anti-peep films are produced. Anti-peep films can effectively prevent others from observing the screen of electronic products from the side angle, because the anti-peep film will be provided with an anti-peep structure layer, which can be specifically understood as a transparent structure film of a blind. The colored ink is mainly filled into the concave position of the surface of the anti-peep structure layer, so that light can pass through the anti-peep structure layer at a preset specific angle in the anti-peep layer. However, when making the anti-peep film, an additional anti-peep structure layer is required, which will increase the cost of the anti-peep film, and the number of bonding layers will increase. In addition to the increased cost, the production process also needs to be increased. Therefore, a new anti-peep protective film is needed that can prevent peeping while reducing the number of layers.
[0003] In addition, some mobile phones are designed with curved screens. If the above-mentioned protective film is still used, the edge may not be covered. Therefore, the corresponding protective film will be made into a mobile phone film with curved edge and soft properties. Utility Model Content
[0004] The utility model aims to provide an anti-peeping soft film to overcome the deficiencies in the prior art.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A privacy-preventing soft film comprises a film body, wherein the film body comprises an OCA layer, a PET substrate layer and a frosted layer, wherein one side of the PET substrate layer is coated with the frosted layer, and the other side of the substrate is provided with a protrusion, the OCA layer is bonded to the side of the PET substrate layer coated with the frosted layer, the outer wall of the protrusion structure is coated with a light-blocking material, and a pair of extended edges of the film body are provided with a bonding portion bent toward one side.
[0007] To further explain, the light-blocking material is ink.
[0008] To further explain, a PET protective layer is bonded to one side of the frosted layer that is not bonded to the PET substrate layer.
[0009] To further explain, a silicone release film is bonded to one side of the OCA layer that is not bonded to the PET substrate layer.
[0010] To further explain, the OCA layer is coated on a side wall of the PET substrate layer having a protrusion structure and fills the concave part of the adjacent protrusion.
[0011] To further explain, the protruding structure is a trapezoidal structure.
[0012] To further explain, the protruding structure is a wave-shaped structure.
[0013] To further illustrate, the thickness of the PET layer is 15-250 μm.
[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0015] The utility model reduces the number of layers of the privacy film while ensuring that the light is transmitted only at a specific angle, that is, the purpose of privacy protection, reduces the production process and reduces the cost. The edge of the privacy film for mobile phones is provided with an inwardly concave wrapping edge, which can well wrap the curved edge of the mobile phone film to protect the mobile phone screen. One side wall of the PET layer is also frosted to effectively prevent fingerprints and enhance the touch texture. BRIEF DESCRIPTION OF THE DRAWINGS
