Patent ID: 8075138

Claim:
A system comprising: one or more 2-D image projectors; and a display screen optically coupled to said 2-D image projectors; wherein the 2-D image projectors are configured to project individual 2-D images substantially in focus on the display screen; wherein each pixel from each of the 2-D images is projected from the display screen into a small angular slice to enable a viewer observing said display screen to see a different image with each eye, wherein the image seen by each eye varies as the viewer moves his or her head with respect to the display screen wherein the display screen is diffusive with a diffusion angle α (full-width at half-maximum, FWHM) in the horizontal plane and a diffusion angle β (FWHM) in the vertical plane; wherein the 2-D image projectors are arranged in one or more horizontal rows with a horizontal displacement angle substantially equal to α/2 between each projector and the next least horizontally displaced projector in any of the rows, wherein the horizontal displacement angle is measured from the display screen.
