Three-dimensional display tech is coming to all sorts of gear, from TVs to strange desktop prototypes from Sony. And now, thanks to 3M and thin-film tech, it could be making it onto the tiny LCD of your favorite cell phone.
So what’s the advantage? You’re unlikely to view 3-D movies on your phone–remaining immobile for the entire length of Disney’s Up would be tricky, if not impossible. But it’ll be useful for gaming, and for providing little visual cues to spruce up a graphical UI. And as smartphones get more complicated, this kind of technological tweak is exactly the sort of thing that could make them both easier to use and more fun.
