A new patent awarded to Apple reveals an interesting new way to create a 3D autostereoscopic display. Rather than a parallax barrier, their display uses tiny pixel-sized domes that can effectively ‘project’ different visuals in different directions, enabling a 3D effect when viewed and then have some true multi-viewing angle effects.
It states: “An exceptional aspect of the invention is that it can produce viewing experiences that are virtually indistinguishable from viewing a true hologram.
“Such a “pseudo-holographic” image is a direct result of the ability to track and respond to observer movements.
“By tracking movements of the eye locations of the observer, the left and right 3D sub-images are adjusted in response to the tracked eye movements to produce images that mimic a real hologram.
Of course, rumors abound that the iPhone4 will boast a holographic display, and other such extravagance. This technology is probably still a few years away from being producable, and then will require some interesting software development to make it work.
