主权项

1. A 3D projector comprising:
a rotatable hollow cylinder having more than one differently polarizing sections; three digital micromirror devices; and a prism configured to split a light beam into three primary color components and to direct each of the primary color components separately to the three digital micromirror devices; wherein a light beam is capable of being passed generally orthogonally through a wall of the hollow cylinder and wherein the 3D projector projects images that are perceived as 3D images; and wherein the 3D projector has two modes, a 2D mode and a 3D mode, and the projector presents twice the number of frames per second in the 3D mode compared to the 2D mode.
