3D without glasses works with a super bright LED light box which is then used to backlight a special 3D image that can be viewed without glasses for a display, where images appear to float in front of the screen. While optimum viewing distance is 3 metres head on, the infinite depth allows angled views of the display. The viewer can fully immerse themselves in the 3D image and most people side step to capture the different viewing angles, this lends well to advertising as it stops the passing shopper to witness the effect.
With the ever growing popularity of 3D televisions & movies in the last few years it was only a matter of time before 3D was used in advertising. The only obstacle was the 3D glasses. Now that this obstacle has been removed it opens up a whole new generation of advertising possibilities where the advertised image will stop customers to wonder at the 3D graphics.
