A diffuser is basically a thin piece of plastic that takes the light source and spreads it evenly across the full width of the display (though, if you’ve ever seen a cheap or old LCD monitor, the diffuser sometimes does a pretty bad job of it). A strip of LEDs along the edge doesn’t provide very even illumination, and so a diffuser must be used. A modern LCD monitor, like the one on your laptop, usually has a backlight that consists of LED strips along the bezel. The technology behind HP Labs’ 3D display is essentially a special backlight. The prototype display produced by HP Labs, however, produces full 3D images that appear to protrude up to one centimeter in front of and behind the display. “For example, if you were to display a 3D image of planet Earth with the North Pole facing out from the screen, by turning your head around the display, you would actually be able to have a view of any country on the globe, you would be able to see all the way around,” says David Fattal, the project’s team leader. Most of these devices use horizontal parallax, which does produce a 3D image - but only in the horizontal (left/right) plane, and usually only within a viewing arc of a few degrees move your head too far to the side, or just slightly up or down, and the 3D effect is broken.

Over the last couple of years, a few portable devices with glasses-free 3D have come to market - most notably the Nintendo 3DS. The current prototype devices can produce full-parallax 3D images and videos that are viewable from up to a meter, within a 90-degree arc - and, like the Star Wars hologram, the 3D image or video varies as you move your head up and down, or around the display. Researchers at HP Labs have built a small, multi-angle, glasses-free 3D display that could allow for smartphones, tablets, and watches to produce Princess Leia-like holograms.
