Making a Privacy Monitor From an Old LCD

ryzvonusef writes "Instructables Member 'Dimovi' utilized a spare LCD monitor and converted it into a 'privacy' monitor. He took apart the monitor's plastic frame, cutting out the polarized film with a utility knife and removed the film adhesive from the glass panel before reassembling the monitor, which now shines a bright white regardless of what is actually being displayed on the screen. He then removed the lenses from a pair of theater 3D glasses, and replaced it with the polarized film he had just removed from the monitor. Now, he is the only one who can see what he is doing on his computer."

Sunglasses

He's the only person who can view it, apart from any clown with a pair of polarising sunglasses. What a gimp. Better off putting the effort into something worthwhile. It's easier to just use your computer in a room with a closed door.

Sunglasses have horizontal polarization. It's aimed at preserving the light reflected from horizontal surfaces, while filtering half of the light comming directly from the Sun.

Sony kind of came out with that...the Playstation Display allows for two people to play fullscreen simultaneously.

Why not just buy a 3M privacy filter?

Recycling is cool and all, but it's not like this is a new / unique / unanticipated capability:

It wasn't a scifi story. Edwin Land, Mr. Polaroid himself, did a lot of research in the area and proposed a combination of headlights and windshields. I remember reading a pretty interesting article in New Scientist about it.
