ABSTRACT:
A transparent, rear-light projection screen that has lenses on its back side facing the projectors for paralleling light from the projectors. The screen on its front side has upright, forerunning asymmetric cylinder lenses with partially reflecting projections having light-refractive surfaces, facing outwardly from the front side and opposite to the direction from which the paralleled light originates from behind. The projection screen improves the color contrast and increases the projected light when the screen is viewed from a side direction.
