Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of peep-proof film, especially to a 360-degree peep-proof film. BACKGROUND

[0002] Peep-proof film is a functional film used for protecting the privacy of screens and is widely used on the screens of electronic devices such as mobile phones, computers and tablets. Traditional peep-proof films mainly achieve the peep-proof effect through micro grating structures or special coatings, but their peep-proof angles are limited, and they can only prevent others from peeping within a specific angle range, and there is still a risk of privacy leakage at other angles.

[0003] Traditional peep-proof films can only achieve peep-proof effect in a single direction (such as left and right or up and down) and cannot achieve omnidirectional privacy protection. Traditional peep-proof films are mostly designed as light films, which are not suitable for screens of different sizes, and in order to effectively enhance the peep-proof angle of the peep-proof film, a peep-proof film is usually added to the single-angle peep-proof film. When multiple peep-proof films are attached, the light films are prone to misalignment and have low attachment efficiency. SUMMARY

[0004] The utility model aims to solve at least one of the technical problems in the related art to some extent.

[0005] To this end, the utility model provides a 360-degree peep-proof film, which achieves omnidirectional peep-proof privacy and protection effect, has high light transmittance, is easy to install, has strong durability and other characteristics, and significantly improves the user experience.

The left and right peep-proof assemblies are arranged on the base layer, the attachment adhesive is attached to the left and right peep-proof assemblies, and the up and down peep-proof assembly is arranged on the attachment adhesive. The up and down peep-proof assembly comprises a bottom film, a light transmission part and a light shielding part. The bottom film is arranged on the attachment adhesive, the light transmission part is linearly arrayed on the bottom film, and the light shielding part is linearly arrayed on the light transmission part.
