Abstract
The present invention is a 3D/2D convertible color projection display system with two color LCoS panels, which enable the system to project two orthogonal polarized images. When the two images correspond to different view angles, each eye of an observer wearing a pair of polaroid glasses can only see one of the images, creating a 3D stereoscopic effect. When the two images correspond to the same view angle, then the observer, without any special glasses, can watch regular 2D images with multiple primary colors.
