I helps When you dont want anyone to see what are you doing on your system, especially if your are working on some secret projects and Offcourse porn also Lol.


I my HP Pavillion Notebook DV6000, if someone tries to see from a angle the person will just see inverted colours as you are seeing Negatives, sometimes it looks annoying as if someone is seating with me but at an angle they complain that they are not able see the contents clearly. But at other times it looks beneficial.
