What is a privacy screen?

A privacy screen is a dual-purpose accessory that not only shields your screen from scratches, like a typical screen protector made of PET film or tempered glass but also adds an extra layer of security. This added layer, known as an anti-spy feature, effectively narrows the viewing angle of your display, preventing unauthorized individuals from peering at your screen and safeguarding your sensitive data from prying eyes.

Do you need a privacy screen protector?

The need for a privacy screen protector is relatively low, as only a minority of people use them, so the short answer is no. However, the concept of “visual hacking” is a real thing. This refers to situations where someone nearby attempts to snoop on your phone or laptop when it’s just within their line of sight. If you’ve ever found yourself tilting your phone away from someone’s eyes sitting next to you, then a privacy screen protector can be a valuable solution. It helps ensure that your on-screen content remains confidential and protected from curious glances, making it a useful accessory for those who prioritize their privacy in public settings.

How do privacy screen protectors work?

Privacy screen protectors typically employ micro louver technology, which allows light from the screen to pass through only at specific angles, similar to the operation of Venetian window blinds, but at a microscopic level. These protectors feature a filter layer with a narrow front angle, usually set at 60 or 90 degrees. When viewing the screen from outside this angle, the content becomes obscured or invisible to onlookers, ensuring that only the intended user can see the displayed information, effectively safeguarding privacy in crowded or public spaces.
