...HOLOGRAPHIC DISPLAY SMARTPHONES!! Light-field displays for mobile devices might be only a year away: - Looking at a stereoscopic 3-D display takes some mental gymnastics. When you look at objects in real life, your brain expects the area of focus to be the same as where your eyes need to converge. But in order to see in stereoscopic 3-D—in which a different image is presented to each eye—you focus on the screen but your eyes converge where the image appears to be. For some, this is a headache-inducing dilemma. Holograms get around that by projecting light right to the spot where your eyes would focus: The light beams travel through that point and hit your eyes just as if they’d come from an object that was actually there. Even better, holograms work from any angle and don’t require glasses. Up until now this type of display has been a weighty affair, requiring large projectors and screens or a very restricted viewing angle. But two companies, Ostendo Technologies and Hewlett-Packard spin-off Leia, promise to put such holographic displays—more properly called light-field displays—in your pocket within a year or two. It might not be Princess Leia projected from an astromech droid, but it’s close. At Display Week in June, Ostendo demonstrated the culmination of nine years of work, an array of eight Quantum Photonic Imager (QPI) chips in a grid projecting three spinning green dice—one seemingly floating behind the display, one at chip level, and the third in front of the chips. “Almost every display you see emits light that goes everywhere,” says Hussein El-Ghoroury, Ostendo’s CEO. “In contrast, the QPI collimates the light to a very narrow angle before emitting it, so you can emit different images in different directions.” Ostendo’s 3-D images are viewable from 2,500 perspectives...
