Smartphone screen protector enables 3D viewing

MIT Technology Review : A Singapore company called Nanoveu is marketing a plastic screen protector for smartphones and tablets that allows users to view three-dimensional content. The EyeFly3D, based on lenticular lens technology , comprises half a million tiny lenses, each sitting above a single pixel image on the LCD display. The lenses send separate images to the left and right eyes to create the illusion of depth. Through the use of nanoimprint lithography , Nanoveu has been able to mass produce the screen protectors at relatively low cost. Selling for just $35, the EyeFly3D promises both high-quality 3D viewing and distortion-free 2D viewing, writes Mike Orcutt for MIT Technology Review.
