“Holographic” displays for smartphones may appear in a couple of years

    Most of us tried to strain our eyes, looking at “three-dimensional” pictures, adapted to red-blue or polarizing glasses in movie theaters, some used 3D TVs, someone even made 3D glasses from a smartphone.
    But it would be great to see a three-dimensional picture without any efforts and additional devices!
    Company Ostendo Technologies in July 2014 demonstrated the fruits of nine years of work - three-dimensional "holographic" microprojector .

    It is claimed that a single projector on a chip (a small one suitable for embedding in a smartphone) can project an image on a surface with a diagonal of more than 120 cm. Several chips can create larger and more complex images.

    In a recent test, Ostendo demonstrated an image of a dice using six micro-projectors. Eyewitnesses claim that the image was clearly visible regardless of the position of the observer.
    The hologram effect is achieved due to the ability of the projectors to produce different images depending on the viewing angle.
    On the chip, there are about a million pixels of 5x10 microns, which have layers of R, G and B, as well as a blue micro-LED, each with its own microprocessor. This "multi-core" allows you to process images in real time, because Pictures should be rendered for each of 2500 declared perspectives (viewpoints).
    Each pixel emits a narrow beam of light. The resulting effect, the creators called the "light field".

    Company and Leia(yes, apparently in honor of that very princess) she went the other way - they are trying to place a specially made polyhedral glass in front of the LCD-display, so that it redirects the rays of light from different diodes in different directions. True, this method provides only 64 different points of view. In my opinion, we all saw a similar effect on “live” calendars.

    I think marketing and the porn industry are already biting their nails.
