Directional projection display
First Claim
1. A system comprising:
- at least one light source to provide 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 light source, the display surface including;
a first plurality of elements positioned to direct the first light received from the at least one light source toward a first side of the display surface; and
a second plurality of elements positioned to direct the second light received from the at least one light source toward a second side of the display surface that is different from the first side of the display surface.

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.

5. A display surface comprising:
-
a first plurality of elements to direct first light towards a first side of the display surface; and a second plurality of elements to direct second light toward a second side of the display surface that is different from the first side; and wherein the first plurality of elements allows the second light to substantially pass through the first plurality of elements based on at least one of a difference in wavelength range or a difference in polarization between the first light and the second light. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)

14. A method comprising:
-
providing first light corresponding to a first image onto a display surface that includes;
(i) a first plurality of elements configured to direct the first light toward a first side of the display surface and away from a second side of the display surface, and (ii) a second plurality of elements configured to direct the second light toward the second side of the display surface and away from the first side, wherein the first plurality of elements are alternated with the second plurality of elements in a pattern formed at least one of laterally or longitudinally across the display surface; andproviding the second light corresponding to the second image on the display surface, wherein the first image is viewable from the first side of the display surface and the second image is viewable from the second side of the display surface. - View Dependent Claims (15, 16, 17, 18, 19)
