"Holographic" displays for smartphones can appear in a couple of years

Most of us have tried to strain your eyes, considering "three-dimensional" picture adjust to the red-blue glasses or polarization in theaters, some used the 3d-TV, some even master-3d-glasses of the smartphone.
But it would be great to see the three-dimensional image without any effort and additional devices!
Company Ostendo Technologies in July 2014 showed the fruits of nine years of work - three-dimensional "holographic" microprojector .



It is alleged that one projector on a chip (small, suitable for installation in a smartphone) can project an image on the surface of a diagonal of 120 cm. Several chips can create more and more complex images.



In a recent test, the company demonstrated Ostendo image of a die using six microprojector. Eyewitnesses claim that the image was clearly visible regardless of the position of the observer.
The effect of the hologram is achieved through a projector's ability to issue different images depending on the viewing angle.
The chip is located about one million pixels 5x10 microns which have layers R, G and B, and blue mikrosvetodiod, each with its own microprocessor. This "multi-core" allows you to process images in real time, as Pictures must be rendered for each of the 2,500 announced perspectives (viewpoints).
Each pixel emits a narrow beam of light. The resulting effect of the creators call "light field".



Company and Leia (yes, apparently in honor of the very princess) went the other way - they try to arrange a special way made многогранное glass before LCD-display, so that it redirects the light rays from different diodes in opposite directions. However, this method only provides 64 different viewpoint. In my opinion, a similar effect, we have all seen on the "live" calendar cards.
