Directional projection display
First Claim
1. A system comprising:
- at least one projector to project first light corresponding to a first image and second light corresponding to a second image, wherein the first light is within a first wavelength range and the second light is within a second wavelength range that is different from the first wavelength range; and
a display surface to receive the first light and the second light from the at least one projector, the display surface including;
a first plurality of reflectors positioned to reflect the first light received from the at least one projector toward a first side of the display surface, the first plurality of reflectors including a first treatment configured to reflect the first light and not reflect the second light; and
a second plurality of reflectors positioned to reflect the second light received from the at least one projector toward a second side of the display surface, different from the first side of the display surface, the second plurality of reflectors including a second treatment configured to reflect the second light and not reflect the first light.

Abstract
In some examples, a projection display surface is configured to reflect a first image or image portion in a first direction and a second image or image portion in a second direction. In some cases, first light corresponding to the first image is projected onto a display surface that includes a first plurality of reflectors configured to reflect the first light in a first direction, but not reflect second light corresponding to the second image. The display surface may further include a second plurality of reflectors to reflect the second light in a second direction, but not reflect the first light. In some examples, the first light is within a first wavelength range and the second light is within a second, different wavelength range. In other examples, the first light has a first polarization and the second light has a second, different polarization.

4. A display surface comprising:
-
a first plurality of reflectors oriented to reflect first light in a first direction; and a second plurality of reflectors oriented to reflect second light in a second direction that is different from the first direction, wherein; based on at least one of a difference in wavelength range or a difference in polarization between the first light and the second light, the first plurality of reflectors do not substantially reflect the second light and the second plurality of reflectors do not substantially reflect the first light. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12)

13. A device comprising:
-
a substrate having a surface, a first side and a second side; a first plurality of reflectors on the surface and positioned to reflect light in a first direction toward the first side, but not toward the second side; and a second plurality of reflectors on the surface and positioned to reflect light in a second direction toward the second side, but not toward the first side, wherein a first portion of an image projected onto the substrate is reflected substantially toward the first side and a second portion of the image is reflected substantially toward the second side. - View Dependent Claims (14, 15, 16, 17)

projecting first light corresponding to a first image onto a display surface that includes a first plurality of reflectors configured to reflect the first light in a first direction, but not reflect second light corresponding to a second image, and a second plurality of reflectors configured to reflect the second light in a second direction, but not reflect the first light; and projecting the second light corresponding to the second image onto the display surface, wherein the first image is reflected in the first direction and the second image is reflected in the second direction. - View Dependent Claims (19, 20, 21, 22)
