Abstract:
A projection screen with micro lenses or micro mirrors for the purpose of suppressing ambient light by means of a patterned layer stack including at least a polarizer and a quarter wave retarder. The projection screen has a surface structure where light from a projector is focussed at positions where the light can escape from the structure and is optionally diffused. The location of the focus positions depends upon the incident angle of the light coming from the projector, and therefore the screen is tailored for a certain projector configuration and projector light direction.

Claim (Index 57):
A reflective projection display screen for use with one or more projectors, the projection display screen having a screen area covered with a patterned layer stack customized to accept projector light from only one projection direction per projector, the projection display screen comprising:\n a first retarder, a micro-lens array of mirrors for focussing light from at least one projector at focus positions where the light can escape from the patterned layer stack, a layer defining the patterned layer stack that is different at the focus positions than in the remainder of the screen area, and comprising a polarizing layer at least in said remainder of the screen area, wherein the patterned layer stack accepts only light coming from one projector direction per projector, whereas reflection of any light coming from another direction is reduced or suppressed, wherein the layer defining the patterned layer stack is a photo-alignment layer.
