(PhysOrg.com) -- Today at the DC Expo in Tokyo, Sony has introduced a new 3D display that can be viewed from any direction. Unlike many 3D displays, the new display does not require glasses to view the 3D images, and several people can view the display simultaneously from multiple angles.
The cylindrical display case is 27 cm tall with a base of 13 cm in diameter, and features a 96 by 128-pixel resolution that looks better than might be expected. The screen displays 3D objects including a cartoon character, car, globe, and people. Sony created these objects either in 3D on a computer or by taking photographs of them from various angles. The result is that the objects appear to have depth, and can be viewed from any angle on the horizontal plane by walking around the display screen.
Sony is not explaining how the technology works, other than mentioning that it uses an LED light source. The company said that it took about three years to develop the two prototypes that are on display at the DC Expo, and it hopes to make versions with larger screens in the next year or so.
The 360-degree 3D display could have a variety of applications in education and entertainment, and Sony vice chairman Ryoji Chubachi said the company will listen to application ideas from visitors. There are currently no plans to market the device until applications are developed.

It just looks like a 3d image being projected onto a 2d surface. Even though this might actually be '3D' it does not look like it. Its not that impressive.
each eye views the display from slightly different angles so you would see it as 3D at least from a horizontal plane, right? Maybe a suspended sphere for full top and bottom views, but I assume that would require a lot more data to produce. Sorry to 2 you my finger slipped-
unless you were there you *are* viewing it in 2D on a 2D surface which might be one of the reasons that it looks that way.
Did you get the part where he said 'it's a prototype'?
There have been a lot of 3D display technologies developed in the past 20 years, this is just another one, probably based on a spinning disk inside that gets very precise illumination at specific points while the disk spins. If so, they are the latest in a long string of such developments.
There is another kind that uses a flexible mirror membrane that is vibrated by a loudspeaker coil which varies the focal length dynamically and laser pulses give much the same effect although with that technology you can't walk around it, the effect is directional but very effective in its angular range.
Also the part of the screen you actualy watch has to be fairly small compaired to a regular tv screen so that seems like a limiting factor.
