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.

Abstract: Filter glasses for use with a stereoscopic digital display system that displays stereoscopic images including left-eye images and right-eye images. The left-eye images are formed with light in a plurality of left-eye spectral bands, and the right-eye images are formed with light in a corresponding plurality of spectrally-adjacent right-eye spectral bands. The filter glasses include a left-eye filter and a right-eye filter, each of which includes a dichroic filter stack and one or more absorptive filter layers. Each of the filters transmits 50% or more of the light in the corresponding eye spectra bands, while providing less than 5% crosstalk. A frame is used to position the right-eye filter in front of an observer's right eye and to position the left-eye filter in front of the observer's left eye.

The other lens elements are fabricated using glasses having a negligible or a moderate susceptibility to thermal stress birefringence, at least one of the other lens elements being fabricated using a glass having a moderate susceptibility to thermal stress birefringence.

Abstract: A stereoscopic digital projection system that projects stereoscopic images including first-eye images and second-eye images onto a display surface. The first-eye images are formed using red, green and blue first-eye light emitters having corresponding spectral bands with red, green and blue first-eye central wavelengths, ?R1, ?G1 and ?B1.

An image forming system including at least one spatial light modulator is used to form first-eye and second-eye modulated images by modulating light from the first-eye and second light emitters. Projection optics are used to deliver the first-eye and second-eye modulated images to a display surface.

Abstract: A stereoscopic digital projection system that projects stereoscopic images including first-eye images and second-eye images. The system includes one or more narrow-band, solid-state, tunable light emitters, each being controllable to alternately provide emitted light in a first state in a corresponding first spectral band and emitted light in a second state in a corresponding second spectral band.
