One thing that amuses me most in all audio video entertainment is the 3D. And then one day while browsing the internet I read in a blog that 3D phones were already out. The article was about sharp aquos which is a new 3D phone. I also read in a magazine that there are two kind of 3D screens for a few we need to wear the glasses. The others don’t require any glasses. So which one of these types is aquos screen. What are the advantages and disadvantages of both type of screens?
