I thoroughly enjoy 3D films when it’s done properly, but for 3D to become something more than just a novelty, there has to be a way to get rid of those polarized glasses. And that’s where innovations like 3M’s new optical film comes into play. It features small, dome-shaped lenses on the surface of the film combined with prism-like structures on the underside to create a 3D effect that is visible with the naked eye.
Now unfortunately the film can’t just be applied to any LCD giving it instant 3D capabilities. The display has to have independently controlled LED edge lighting on the left and right side which is used to distinguish the different images meant for the left and right eye. However, the film allows the LCD to be easily switched between 2D and 3D modes, and has already gone into production for small and medium sized displays.
