A privacy screen protector is a type of screen film designed to protect visual privacy, commonly used on devices such as smartphones, tablets, and laptops. Its primary function is to prevent onlookers from viewing the screen content from side angles. The composition of a privacy screen protector typically consists of the following layers.

In summary, the anti-peeping principle of anti-spy films relies on the internal micro-louver structure to control light propagation. This ensures that screen content can only be clearly seen within a certain front-facing angle, while it becomes blurred or invisible from the side due to light obstruction, thus protecting the screen content from being peeped at by others.

A privacy screen protector is a specially designed protective film for mobile phone screens. Its primary function is to prevent others from peeking at your screen by limiting the viewing angles. When applied to the phone screen, only the person viewing it directly from the front can see the content clearly. From side angles or wider perspectives, the screen appears darkened or blurred, thereby achieving the effect of privacy protection.

In the photo-curing formulation system, apart from UV resins and photoinitiators, UV monomers also serve as a vital component. UV monomers not only adjust the viscosity of the system but also impart or enhance different properties of the cured film, such as enhancing adhesion, improving flexibility, and increasing wear resistance. Therefore, the rational use of various monomers is also an important link in formulation design.
