ABSTRACT:
A three-dimensional rear projection screen that has substantially improved contrast by using a tinted layer disposed between the source of the projected light and the light diffusion layer. This tinted attenuation layer diminishes the back-scattered light more than it diminishes the desired forward-scattered light which makes up the image on the screen. The contrast of the image is thus improved because the reduction of the back-scattered light relative to the forward-scattered light diminishes the degradation of contrast caused by the impingement of spurious light onto opposite portions of the rear projection screen.
