Abstract
A system can include a projection layer. The projection layer can include a plurality of pixels. The plurality of pixels can be electronically controllable to vary appearance of at least one of the plurality of pixels in coordination with an image projected onto the projection layer.
Claims34
A system, comprising:
- a projection layer comprising an inner layer and an external layer, wherein the external layer is between the inner layer and a projector, wherein the projector is external to the projection layer and the projection layer is in front of the projector, the external layer including a plurality of pixels that is electronically controllable to vary appearance of at least one of the plurality of pixels in coordination with an image projected onto the projection layer from the projector;
- wherein the inner layer is configured to display as a solid white surface and each pixel of the plurality of pixels of the external layer is individually addressable to be transparent, black, or grayscale;
- or
- wherein the inner layer is configured to display as a solid black surface and each pixel of the plurality of pixels of the external layer is individually addressable to be transparent, white, or grayscale.

A method, comprising:
- providing a projection layer comprising an inner layer and an external layer between the inner layer and a projector, wherein the projector is external to the projection layer and the projection layer is in front of the projector, the external layer including a plurality of pixels that is electronically controllable to vary appearance of at least one of the plurality of pixels in coordination with an image projected onto the projection layer from the projector;
- wherein the inner layer is configured to display as a solid white surface and each pixel of the plurality of pixels of the external layer is individually addressable to be transparent, black, or grayscale;
- or
- wherein the inner layer is configured to display as a solid black surface and each pixel of the plurality of pixels of the external layer is individually addressable to be transparent, white, or grayscale.
1 more element
A method, comprising:
- controlling a plurality of pixels of a projection layer to vary appearance of at least one of the plurality of pixels in coordination with an image projected onto the projection layer from a projector, wherein the projector is external to the projection layer and the projection layer is in front of the projector;
- wherein the projection layer includes an inner layer configured to display as a solid white surface and an external layer between the inner layer and the projector and having individually addressable pixels of the plurality of pixels, wherein the controlling includes controlling each of the individually addressable pixels of the plurality of pixels to be transparent, black, or grayscale;
- or
- wherein the projection layer includes an inner layer that is configured to display as a solid black surface and an external layer between the inner layer and the projector and having individually addressable pixels of the plurality of pixels, wherein the controlling includes controlling each of the individually addressable pixels of the plurality of pixels to be transparent, white, or grayscale.
