Abstract

A multi-layer projection screen includes a stray light rejection layer and a lens array. The stray light rejection layer includes an array of pillar structures, wherein each pillar structure of the array of pillar structures includes an entrance aperture, an exit aperture, a pathway extending from the entrance aperture to the exit aperture, and a side wall surrounding the pathway. The lens array is optically aligned to the array of pillar structures. The stray light rejection layer blocks display light received from the lens array having an oblique trajectory that is greater than a threshold angle from a first trajectory.
