A projection display system (100; 200; 1300) includes a first polarizer (104), a transparent screen (108), a second polarizer (106) on the transparent screen, and a projector (102) for projecting an image through the first polarizer (104) and onto the transparent screen (108). The first and the second polarizers have different polarization directions (105, 107) so that the image is visible from a first side of the transparent screen and invisible from a second side of the transparent screen. |
