Zusammenfassung:A projection screen includes a transparent substrate having a front side and a backside, a dark film disposed across the front side of the transparent substrate, an array of holes disposed through the dark film, a diffusing layer disposed between the transparent substrate and the dark film, and an array of lenses disposed across the backside of the transparent substrate. The array of lenses are aligned to focus display light incident through the array of lenses towards the array of holes and the diffusing layer diffuses the display light for emission out the array of holes as diffuse display light.
