What are 3D displays?
Traditionally, images are presented in 2D to the world: printed media, billboards, TV, computer or mobile phone. Since years 3D systems and technologies are used to give (moving) images more depth (e.g. 3D games, 3D virtual worlds, 3D movies in special theatres). But these systems and technologies do not have the full possibility to project real 3D in a simple manner (e.g. without headset). However, Philips introduced 3D displays that give to possibility to watch real 3D images without special headsets. See picture below. Philips 3D display (courtesy of Philips 3D Solutions) These types of 3D displays offer means to give (moving) images a very special dimension: depth! These displays are to be used as 3D narrowcasting and digital signage screens, screens to present products on events, displays for the game scene, or to support visualisation processes in e.g. medical, construction or energy sectors.
3D displays are displays that project images which appear 3-dimensional. Early models require the use of stereoscopic goggles, and will not be truly 3D, but some scientists expect full-fledged 3D displays to hit the market by around 2015. A primary limitation is that holograms are only designed to be viewed from one angle. Research towards making 3D displays possible focusing on head-tracking optics designed to follow a viewer’s gaze from around the room, or holographic projections that can be viewed from more than one angle. Holograms and other 3D display attempts have been around for decades, but it will still be a while before we see the technology on shelves. A company called IO2 technology has created a display called the M2i which can project full-color 3D display images in thin air, available today for about $20,000 US Dollars a unit. The display uses a rear projection system to create images in what they call “transformed air.” The images look somewhat ethereal. However, the te
