Japanese NICT and the Kobe University developed a thin-panel type device, which generates auto 3D images in the air.
Unlike holographic displays this one does not need a special optical system.
The current system just needs an object placed under it and it will display a floating 3D image of it above the panel.
This sounds similar to theses mirage 3D bowls, where the object placed inside the bowl appears to be floating above it. I am not sure though if this system could be used with a computer display or video feed.
