Abstract
An auto-stereoscopic display which includes a screen substrate having a first face and a second face. A lenticular array having a plurality of lenticules extending in a first direction and a second direction is affixed to the first face. A plurality of first elongated light filters is affixed to the second face. The first elongated light filters extend parallel to the plurality of lenticules and are adapted to pass light waves having a first orientation. A plurality of second elongated light filters extending parallel to the plurality of lenticules is affixed to the second face and adapted to pass light waves having a second orientation.
Claims18
A projection display, comprising:
- a screen substrate having a first face and a second face;
- a lenticular array comprising a plurality of lenticules extending in a first direction and a second direction, the lenticular array affixed to the first face, wherein each of the plurality of lenticules has a first width;
- a plurality of first elongated light filters extending parallel to the plurality of lenticules, affixed to the second face, and adapted to pass light waves having a first orientation received from a first projector, wherein each of the plurality of first elongated light filters has a second width that is about one-half of the first width;
- and
- a plurality of second elongated light filters extending parallel to the plurality of lenticules, affixed to the second face, and adapted to pass light waves having a second orientation received from a second projector concurrently with the light waves having the first orientation, wherein the second orientation is different from the first orientation, wherein each of the plurality of second elongated light filters has the second width, and wherein each of the plurality of first elongated light filters is adjacent to at least one of the plurality of second elongated light filters.

A method of providing a stereoscopic image to a projection display, comprising:
- projecting first light waves from a first projector comprising imagery associated with a first perspective of an image at the projection display, the first light waves having a first orientation, the projection display comprising:
- a first face and a second face;
- a lenticular array comprising a plurality of lenticules extending in a first direction and a second direction, the lenticular array affixed to the first face, wherein each of the plurality of lenticules has a first width;
- a plurality of first elongated light filters extending in the first direction and the second direction and affixed to the second face and adapted to pass the first light waves having the first orientation, wherein each of the plurality of first elongated light filters has a second width that is about one-half the first width;
- a plurality of second elongated light filters extending in the first direction and the second direction and affixed to the second face and adapted to pass light waves having a second orientation, wherein each of the plurality of second elongated light filters has the second width, and wherein each of the plurality of first elongated light filters is adjacent to at least one of the plurality of second elongated light filters;
- and
- projecting second light waves from a second projector comprising imagery associated with a second perspective of the image at the projection display, the second light waves having the second orientation and being projected concurrently with the first light waves having the first orientation.

A method of making a projection display, comprising:
- providing a screen substrate having a first face and a second face;
- affixing to the first face a lenticular array comprising a plurality of lenticules extending in a first direction and a second direction, the lenticular array affixed to the first face, wherein each of the plurality of lenticules has a first width;
- affixing to the second face a plurality of first elongated light filters extending in the first direction and the second direction and adapted to pass light waves having a first orientation received from a first projector, wherein each of the plurality of first elongated light filters has a second width that is about one-half the first width;
- and
- affixing to the second face a plurality of second elongated light filters extending in the first direction and the second direction and adapted to pass light waves having a second orientation received from a second projector concurrently as the plurality of first elongated light filter pass the light waves having the first orientation, wherein each of the plurality of second elongated light filters has the second width, and wherein each of the plurality of first elongated light filters is adjacent to at least one of the plurality of second elongated light filters.
