See-through display

摘要

In a particular embodiment, a see-through display includes a screen having transparent layer of material with a front side and a back side. At least one plurality of shaped louver members is disposed between the front side and the back side. The plurality of the louver members allow transmission of a fraction of light through the screen with minimum scattering within a range of incident angles. The plurality of the louvers also redirect image signal light from an image source into a range of angles centered about a normal to the screen. The louver members combine the image signal light with the light emitted from background objects located on the backside of the screen. The background image light is transmitted through the display screen with minimal scattering. For embodiments providing two sets of louver members, the image signal light may be redirected to observers on either side of the screen, such that the observers may see each other as well as the intended image.
