ABSTRACT:
A cinema screen may include a housing including at least one of wood and polymer and configured to hold the cinema screen by at least one of gluing and pinching. The screen may include a metalloplastic multi-layer film coupled to the housing and have a relatively small thickness. The multi-layer film may also have a bottom layer that may be translucent and other layers of multi-layer film may be transparent. The screen may also include a plurality of lamps to provide light. The multi-layer film may be configured to diffuse the light, which may be softly filtered thereby to reduce contrasts, and increase a quantity of light information in front of and behind the cinema screen. The light information may vary with a greater softness. The multi-layer film may also be configured to provide relief image playback accuracy.
