摘要
Techniques and mechanisms to provide for improved image display in an area of overlapping projections. In an embodiment, a multi-layer projection screen comprises light sources and collimation structures each disposed over a corresponding one of such light sources. A first collimation structure disposed over a first light source collimates first light from the first light source. The first collimation structure further receives and redirects second light from a second light source disposed under a second collimation structure that adjoins the first collimation structure. In another embodiment, the first collimation structure redirects the other light from the second light source away from the direction of collimation of the first light. A stray light rejection layer of the multi-layer projection screen passes a majority of the first light for inclusion as part of a projected image, and prevents a majority of the second light from inclusion in the projected image.
