The keeper's note

Projection blow-by-elimination show-effect optical hardware (Joseph).

Abstract

A system may comprise a projection surface and a light source. The projection surface may comprise a first layer comprising a material that prevents reflection of light, a second layer comprising a transparent image forming material, and a third layer comprising a privacy screen filter. The second layer may be provided between the first layer and the third layer. The light source may be configured to emit light on the projection surface to create an image on the projection surface. The light source may face the first layer. The light may be emitted at a projection angle on the projection surface. The third layer may cause the projection surface to appear translucent from a viewpoint of the light source emitting the light at the projection angle.

Background

BACKGROUND

A projector is an optical device that projects light onto a surface. For example, the projector may create an image of the surface as a result of projecting the light onto the surface. In some instances, the projector may project the light through a system of lenses to create the image of the surface. SUMMARY

A system may comprise a projection surface and a light source. The projection surface may comprise a first layer comprising a material that prevents reflection of light, a second layer comprising a transparent image forming material, and a third layer comprising a privacy screen filter. The second layer may be provided between the first layer and the third layer. The light source may be configured to emit light on the projection surface to create an image on the projection surface. The light source may face the first layer. The light may be emitted at a projection angle on the projection surface. The third layer may cause the projection surface to appear translucent from a viewpoint of the light source emitting the light at the projection angle.

A transparent projection surface may comprise a first layer comprising a material that prevents reflection of light; a second layer comprising a transparent image forming material; and a third layer comprising a privacy screen filter. The second layer is provided between the first layer and the third layer, and the first layer is configured to receive light emitted by a light source.

Claims

1. A system, comprising: a projection surface comprising: a first layer comprising a material that prevents reflection of light, a second layer comprising a transparent image forming material, and a third layer comprising a privacy screen filter, wherein the second layer is provided between the first layer and the third layer; and a light source configured to emit light on the projection surface to create an image on the projection surface, wherein the light source faces the first layer, wherein the light is emitted at a projection angle on the projection surface, and wherein the third layer causes the projection surface to appear translucent from a viewpoint of the light source emitting the light at the projection angle. || 8. A transparent projection surface comprising: a first layer comprising a material that prevents reflection of light; a second layer comprising a transparent image forming material; and a third layer comprising a privacy screen filter, wherein the second layer is provided between the first layer and the third layer, and wherein the first layer is configured to receive light emitted by a light source. || 16. A method for manufacturing a projection surface, the method comprising: providing a first layer comprising a material that prevents reflection of light; providing a second layer comprising a transparent material; and providing a third layer comprising a privacy screen filter, wherein the second layer is provided between the first layer and the third layer, wherein the third layer comprises a plurality of elements, wherein the plurality of elements cause the third layer to appear translucent when viewed from a first direction that is parallel to the projection angle, and wherein the plurality of elements cause the third layer to appear transparent when viewed from a second direction that is not parallel to the projection angle.
