3M shows new no-glasses 3D display
3M are showing new 3D displays that do not require glasses. 3M are showing two displays - one is 2.8" and the second is 9". These are based on LCD panels with LED backlighting, and 3M are using special film that can steer the light (using apertures and lenses) from the backlight unit to the left-eye and rigt-eye portion of the screen. It's called Conoscopy.
3M are ramping up the volume production of these panels, so they might actually appear in devices soon.
