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.

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. -Physorg
