HIGH-CONTRAST FRONT PROJECTION VIDEO DISPLAY SYSTEM

摘要

A front projection video display system (100) achieves high contrast without darkened ambient room conditions by a specific combination and arrangement of the components of this system. These components include a front-projection video projector (10) which projects an image of particular direction of polarization; polarizing lenses (30) which polarize light radiated from room light fixtures in a direction orthogonal to that of the projected image; a polarizing filter (40) which substantially transmits light polarized parallel to the projected image and substantially blocks light orthogonal to the projected image; and a projection screen (20) which is polarization maintaining and which receives the projected image for viewing by the viewing audience.
