Abstract— A new front‐projection system for large screens by diffusing only projected light to wards the viewing‐angle range and reflecting ambient light towards the other angle ranges is proposed. With this system, a high‐quality and large‐sized front‐projection display with a high contrast ratio even in a bright room has been realized.
