In Tokyo today, Sony unveiled a 3D display that can be viewed from any direction. No glasses required, and several users can see the 3D images simultaneously from various angles. Snip:
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's keeping details under wraps, and hasn't explained how it works. We do know that it uses an LED light source, and that Sony claims it took about three years to develop the two demo models shown off today. The company has no immediate plans to commercialize the device, but a rep says they will develop versions with larger displays within the coming year.
