Holographic 3D for mobile could become a reality

Boffins at Hewlett-Packard Laboratories claim to have created a new type of multidirectional backlit screen that creates the holographic 3D effect.

Current 3D display technology has a lot of limitations. You need to view it wearing special glasses, which can be costly or ill-fitting. With glasses-free 3D, the viewing angle can be small, meaning that if you move slightly too far to either side, the 3D image disappears.

Now, however, a team of scientists, led by David Fattal at Hewlett-Packard Laboratories in Palo Alto, Calif., claim to have created a new kind of 3D display for small screens that is both glasses-free and has a very wide viewing angle.

"None of the leading multiview 3D solutions is particularly well suited to mobile devices (watches, mobile phones, or tablets), which require the combination of a thin, portable form factor, a high spatial resolution and a wide full-parallax view zone (for short viewing distance from potentially steep angles)," says the research abstract in Nature.

"Here we introduce a multidirectional, diffractive backlight technology that permits the rendering of high-resolution, full-parallax 3D images in a very wide view zone (up to 180 degrees in principle) at an observation distance of up to a meter."
