  • Patent number: 10807016
    Abstract: Light emitting displays and sound systems can be used in cinemas for cinema presentations that integrates a sound system to achieve the same or better immersive conditions in cinema theatres with front projection cinema screens. The screen can be active with light emitters, rather than passive and reflect light projected from a projector. Spaces are formed between adjacent light emitters in the display to allow for sound waves to pass from sound wave emitters positioned behind the screen to a cinema seating area in front of the screen. Loudspeakers may be positioned in the spaces. Diffusers or other structures may be positioned proximate to a front of the screen to facilitate visual performance. In addition or in the alternative, loudspeakers can be positioned in each seat of the viewing seating area that produce sound waves that appear to be coming from a non-seating location in the theatre.
