3M 4-way - notebook privacy filter

The four-way privacy filter for ThinkPad Helix utilizes the 3M microlouvre privacy technology to dim the screen and block the vision of wandering eyes from four directions: above and below the tablet, and from both sides. It also guards your screen from scratches and smears. The two-way filter provides privacy from left-right while the tablet is being used in landscape mode. Unlike other generic filters in the marketplace, the Lenovo privacy filter is made specifically for Lenovo products with unique cut-outs specific to the ThinkPad Helix, making it the only product in the marketplace suitable for this tablet.
