Prevent people from borrowing your ideas while you're working on your laptop in a public space by using the 3M widescreen privacy filter, which uses a proprietary technology that makes your screen appear dark to anyone not directly in front of it. The plastic film is made for 27-inch flat-panel monitors and will also protect your screen from accidental scratches. It is reversible to have either a gloss finish or a matte finish that also reduces glare.
This filter is designed for widescreen netbook computers with screens that appear more rectangular than square
Utilizes 3M's microlouver privacy technology so only persons directly in front of the monitor can see the image on screen
