It was not about a month ago that the Optical Systems Division of 3M announced the release of a new 3D film targeted at mobile devices. Now, they were at FPD International 2009 and demoed two devices with the new technology.

Oh, did I mention you don’t need funny glasses to see the 3D image? The technique utilizes multiple LED backlights in tandem with the special film that uses apertures and lenses to direct a picture to the left and right eyes. Further, the film can switch from 3D and 2D mode by changing the operation of the backlights.

They had two devices with the film installed: a 2.8-inch mobile sized screen and a 9-inch picture frame screen. Obviously, the 3D image doesn’t carry over in the pictures, so you will have to use your imagination.

The film is already being put into production for use in smaller devices. 3M also reports that some devices have already adopted the new technology.
