Laser-Powered Giant 3-D Display in the Works

A new glasses-free 3-D display would use lasers to create giant images outdoors for electronic billboards, stadium events, and rock shows, researchers say. The illusion of 3-D comes from how our two eyes see two slightly different views of the world because they are separated by about 6.4 centimeters. The brain fuses those images into a 3-D model of the world. Whereas a 2-D display shows only a single flat image, 3-D displays present a different image to each eye. Nowadays, 3-D movies and TVs show each eye a different image either using polarized glasses or using glasses that coordinate with the TV to shutter one eye then the other . Recently, engineers have developed glasses-free 3-D displays that use screens whose pixels send light in specific directions, as opposed to conventional 2-D display pixels, which send light in all directions. As such, these so-called autostere...
