Abstract:
A light absorbing configuration for a venue in which images are projected to a display screen located at or near a front of the venue, may comprise a light absorbing structure deployed on one or more front portions on one or more of a ceiling, side walls, or a floor of the venue. The light absorbing structure comprises grooves formed at least in part by a first type of light reflective surfaces configured to receive a portion of light rays directly reflected off the display screen and a second type of light reflective surfaces configured to receive light rays reflected off the first type of light reflective surfaces.
