High-contrast front-projection system for large-screen displays suppressing reflection and diffusion of ambient light.

The article proposes a new front-projection system for large screens by diffusing only projected light towards the viewing-angle range and reflecting ambient light towards the other angle ranges. With this new front-projection system, a high-quality and large-sized front-projection display with a high contrast ration even in a bright room has been achieved. It highlights several features of the front-projection displays.
