Privacy screen protection works thanks to an advanced layer of nano-engineered micro-louver technology—also known as nano-louver film.
These microscopic vertical blinds are embedded within the film itself and are designed to control the direction of light. When viewed straight-on, light passes through normally, so you see your screen clearly. But when viewed from an angle (typically beyond 30 degrees), the blinds block the light, making the screen appear black or obscured to anyone next to you.
This ensures that only the person directly in front of the screen can see what's on it—perfect for maintaining privacy in public settings like airplanes, coffee shops, and retail environments.

Q: How does privacy screen protection work?
A: Privacy film uses nano-louver technology-microscopic vertical blinds embedded in the film to block side-angle views while maintaining clear, direct-view visibility.
Q: What viewing angle does it block?
A: Most privacy film blocks views beyond 30 degrees from center, making it hard for people beside you to see your screen. This is very helpful in crowded situations like airports, waiting rooms and other areas where you may have strangers sitting next to you so you can keep your screen private only to you.
Q: Will privacy film affect tough or screen clarity?
A: No. ProtectionPro's Privacy (dry install), Privacy Pro (wet install) and Privacy NX1 (for Nexera ONE machine) films are engineered to retain full touch sensitivity and high screen resolution when viewed head-on.
