Apple Wins Patent for Glasses-Free 3D Display

Posted on December 1, 2010 by

Apple has been awarded a patent for a 3D display system which would display a 3D image to one or more people without the need for special glasses. Apple’s patent describes using a special reflective screen with a rippled texture to create an autostereoscopic projection system, meaning one in which different images are projected to each eye without the need for special glasses. The system tracks the viewer’s eyes and calculates their position in space. It then projects each pixel of the stereoscopic images to a precise spot on one of the screen’s ripples, reflecting it into one or other of the viewer’s eyes. If Apple can do this for one pair eyes, it suggests, it can project multiple images to different points on the ripples for multiple users at the same time.
