Japanese university working on 3D display

The National Institute of Information and Communications Technology (NICT) and Kobe University have jointly developed a thin-panel type device, which forms 3D images in the air. "This device renders transparent, reflected images. Unlike holography, the device needs no special optical system other than itself and features color image production," said a spokesperson. Just by setting a display (or a subject to be shown) under a glass table and laying this device over the table, a "3D display" can be created..
