Patent abstract
A display system includes a projection screen and a projector. The projection screen includes a retarder plate between a polarizer and a transparent screen. The projector projects an image through the polarizer and the retarder plate onto the transparent screen. The image is visible from a first side of the transparent screen but invisible from a second side of the transparent screen because any light passing twice through the retarder plate is blocked by the polarizer.
