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 78):
A method of producing a projection display screen having a screen area and a substrate, the projection display screen comprising: a first retarder, a micro-lens array of mirrors on the substrate for focussing light from a projector at focus positions where the light can escape from the substrate through a patterned layer structure, the method comprising the steps of:\n covering the substrate with a photosensitive layer, exposing the photosensitive layer to light from a light source, the light having an angle of incidence on the substrate identical to the angle of incidence of projector light projected from a projector onto that position on the screen, exposure of the photosensitive layer and subsequent processing steps defining a layer structure that is different at the focus positions, than in the remainder of the screen area; wherein the photosensitive layer is a photo alignment layer and subsequent processing includes the creation of a patterned polarizing layer wherein the polarization direction of the patterned polarizing layer is defined by the photo-alignment layer, or wherein the photosensitive layer is a photo alignment layer and subsequent processing includes the creation of a patterned broadband half-wave retarder wherein the retardation of the patterned half wave retarder layer for the incoming polarization direction is defined by the photo-alignment layer.
