Blackout privacy filters are designed for use in open, high-traffic environments where on-screen data needs to be kept private. The technology makes on-screen information visible only to persons directly in front of the screen without blurring or distorting the image.With mobile devices being used more in public, privacy protection has become an increasingly important issue. Shoulder surfing as it has become labelled, is a growing form of identity theft in which private on-screen information is either viewed or photographed over the shoulders of anyone using a mobile device. Whether you use a smartphone, laptop or tablet, you can protect your privacy in public with PrivaScreen™ Filters. PrivaScreen™ Filters blackout the screen image when viewed from 30º side angles to prevent prying eyes from reading your screen. Yet on-screen data is clearly visible from a straight-on view, allowing you to work worry-free, even on the go.To find the perfect privacy screen for your computer click here.DimensionsAspect Ratio - 16:09Diagonal (inch) - 13.3Width (inch) - 11.5Width (mm) - 292Height (inch) - 6.5Height (mm) - 165Privacy filter fits widescreen laptops with a diagonal screen measurement of 13.3 inch (viewable area only), 16:9 aspect ratio, easy to attach and remove, reduces screen glare to help prevent eye strain, blackout side view when viewed from a 30º side angle, protects screen from scratches and fingerprints, 100% recyclable
