Abstract: Systems for displaying images in a cinema setting can include components to reduce screen-door effect. The systems can include an array of light emitting sources or other active sources of light. In one example, the light emitting source emit pixels of light to a projection lens to project an image represented by the projection lens and a baffle and an aperture stop can block part of the light from the sources that exceeds an allowable cone angle of acceptable of the system. In another example, a display includes the array of light emitting sources and additional elements, such as diffuser elements, positioned in front of the array of light emitting sources.

Abstract: Systems for displaying images in a cinema setting can include components to reduce screen-door effect. The systems can include an array of light emitting sources (102) or other active sources of light. In one example, the light emitting source emit pixels of light to a projection lens (124) to project an image represented by the projection lens and a baffle (150) and an aperture stop (118) can block part of the light from the sources that exceeds an allowable cone angle of acceptable of the system. In another example, a display includes the array of light emitting sources and additional elements, such as diffuser elements, positioned in front of the array of light emitting sources.

Abstract: A light emitting display can be formed from tiles mounted within a certain distance range with respect to each other and with an established blending region positioned towards the edges of the tiles. A tile can be a matrix of light emitting elements, such as LEDs, OLEDs, quantum dots, or other element that emits light. The tolerance of spacing between tiles can allow for less precision in alignment during installation in a theatre, thereby reducing display assembly cost but still maintaining a display for displaying an image at a high quality with reduced or eliminated appearance of visual artifacts between tiles.

Abstract: Light emitting displays can be used in cinemas for cinema presentations that integrate a sound system to achieve immersive conditions in cinema theatres. The cinema screen can include a matrix of light emitters and a diffuser sheet. The matrix of light emitters is configured to form a light-emitting area of the cinema screen. The diffuser sheet includes one or more perforations, and can be positioned between the matrix of light emitters and an audience area in the theatre. The diffuser sheet is positioned with respect to the matrix of light emitters such that the one or more perforations are configured to prevent light outputted by the light emitters from being viewable in the audience area.

Abstract: Light emitting displays can be used in cinemas for cinema presentations that integrate a sound system to achieve immersive conditions in cinema theatres. In an example, a theatre includes a viewer seating area, an active display, and one or more sound wave emitters. The active display includes light emitting elements configured to output, toward the viewer seating area, light representing a visual presentation. The one or more sound wave emitters can be positioned proximate to the viewer seating area. The one or more sound wave emitters are configured to output, toward the active display, sound waves corresponding to at least a portion of sound for the visual presentation. The active display can be positioned to reflect, toward the viewer seating area, the sound waves from the one or more sound wave emitters.

Abstract: A projection system includes a projection lens to project image light along an image light path towards a port window and to redirect a portion of the image light away from the image light path as result of being scattered or reflected away from the image light path. The projection system includes a port window for transmitting projected image light from the projection lens. The port window has a surface for redirecting a portion of the projected image light as result of being scattered or reflected away from the image light path. The projection system includes an enclosure positioned between the port window and the projection lens to surround the image light path between the port window and the projection lens. The enclosure absorbs the portion of the image light redirected by the projection lens and absorbs the portion of the projected image light redirected by the surface.

Abstract: A projection system can direct stereo image content to a display surface using an internally located stereo polarization modulator while avoiding intra-frame contrast degradation from using a stereo polarization modulator. In one example, the stereo polarization modulator is positioned between a spatial light modulator device and imaging optics in the projection system. The imaging optics can prevent part of the imaged light scattered by the stereo polarization modulator from being projected by the projection system, while allowing other light to be projected. Doing so can reduce or avoid intra-frame contrast degradation of the projected imaged light that may otherwise occur because of the presence of the stereo polarization modulator. In this or as a separate example, the projection system can include an enclosure between a port window and a projection lens to absorb the portion of the light scattered by the stereo polarization modulator.

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: Hybrid image projection systems and methods can superimpose image components of an input image. An input image can be divided into smaller regions and at least one parameter of each region can be determined. The input image can be decomposed based on the parameter of each region into multiple, less correlated, orthogonal or quasi-orthogonal image components. Each projector can display respective image components so that the images projected may be optically superimposed on a screen. The superposition of orthogonal or quasi-orthogonal image components can result in superposition of images in an existing multi-projector image systems being more insensitive to inter-projector image misalignment. Superimposing orthogonal or quasi-orthogonal images can be used to avoid visible image degradation, and provide more robust image quality in a multiple projector system implementation.

Abstract: A theatre system is described that includes a screen and a projection system. The projection system includes a first mirror and a second mirror that are positionable within axes for imaged light and between projection lenses of projectors and the screen. The axes include a first axis and a second axis. The first mirror and the second mirror are configured for causing the first axis and the second axis to be parallel to each other and to have a displacement between the first axis and second axis along a dimension by which the screen is curved.

Abstract: Optical systems are provided that include illumination sources, micro-mirror array optical modulators, and an optical element. The micro-mirror array optical modulators can selectively modulate light beams, redirect light by diffraction and reflection, and provide an output modulated light beam that exhibits a diffraction handedness dependent on the spectral bandwidth of the light incident thereupon. The optical element has a color dependent aperture that defines portions of output modulated light beams that are transmitted and remaining portions that are blocked. An efficiency and contrast of each the output modulated light beams acquired by the optical element can be independently determined by a narrow spectral bandwidth of each of the light beams, the spectral characteristics of the color dependent aperture, and the diffraction handedness of the micro-mirror array optical modulators for the associated spectral bandwidth.

Abstract: Embodiments of the present disclosure are directed towards a method of encoding image frames into a multiplexed frame, and a corresponding method of decoding the multiplexed frame. The encoding method includes modifying image frames to generate corresponding processed frames, and generating masking data that indicates how an output frame can be produced from one of the processed frames and another of the processed frames. The processed frames and the masking data can be combined to form a multiplexed frame. The decoding method includes receiving a multiplexed frame containing processed frames and masking data, and unpacking the multiplexed frame to identify the processed frames and the masking data. Once unpacked, an output frame can be generated from the processed frames by combining one of the processed frames with another of the processed frames according to the masking data.
