Online privacy is a pretty big concern. Though most efforts to provide it concentrate on what happens to data after it leaves your computer, there's still the more human element of people sitting right next to you. If you've ever been annoyed by someone peering over at your screen from a seat over, LG has an answer for you with the introduction of notebooks that have adjustable viewing angles. The privacy-minded displays have a default 175-degree viewing angle, which can be toned down to a minimum of 60 degrees. The latter angle is much narrower, making it difficult to see what's on your screen if you aren't sitting directly in front of it. That would be ideal for people on planes or trains who don't want others snooping.
Even if you don't travel often, the benefit of such a device extends far beyond that. In just about any public setting it would be a neat feature to have, from libraries to coffee shops to the increasing number of other places with public Internet access.
Screens with adjustable viewing angles aren't new, and some companies even offer filters that are placed over the screen to adjust it. This is the first deployed attempt to offer such a feat with a simple button press, however.
