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.
An active display can have an increased color gamut and include a group of LED packets that each form a sub-pixel and that together form a pixel for the display. Each LED packet includes at least a red primary color LED, a greed primary color LED, and a blue primary color LED. Each LED can be associated with an intensity value to control the intensity of primary light outputted by the LED. The group of LED packets can output light in a color gamut of a color space for the active display. Each LED packet of the group of LED packets, individually, is configured to output light in the color gamut of a subset of the color space. The active display can display a visual media presentation to an audience. An increased fraction of LEDs from a production batch can be used in the active display.

LIGHT EMITTING DISPLAY WITH TILES AND DATA PROCESSING
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.

An active display (102) can be used in a theatre environment (100) in which content to be displayed by the active display (102) can be delivered wirelessly using emitters (118). The active display (102) can include tiles (104a-104d) with detectors (106a-106d) that can detect the wireless signals. The active display (102) can include circuitry that can interpret instructions from the wireless signals for controlling the output (108a-108d) of pixels on the tiles.
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.

Speckle artifacts as viewed in images projected on a display surface by a projector can be reduced. At least one spatial light modulator, illuminated by one or more light sources, can be imaged to a screen by a projection lens. A deflector subsystem can be provided in image space, proximate to the lens, where the image light emerges. In this location, image light directed to any given field point on the display surface is convergent, but can appear collimated. The deflector subsystem can include a tilted optical plate that is rotated in a plane along an axis. As the deflector subsystem is temporally rotated, the image light to any given field point traverses different optical paths, varying the angular diversity to reduce perceivable speckle by changing at least the angle of incidence to the screen.

A screen can be vibrated by vibrators that are drivable by signals. Each vibrator can be adjacent in position to other vibrators that are drivable by different types of drive signals than a drive signal associated with the vibrator. The number of drive signals can be equal to or less than the number of vibrators. A vibrator assembly for a vibrator can include a baffle and a transducer that couples to the baffle. The transducer can vibrate at least a portion of the screen. The vibrating screen can be monitored by a sensor and an analyzer unit that can analyze image speckle and screen displacement artifacts in captured images of images projected onto the screen and output results of the analysis.

An optical system that includes a micro-mirror array optical modulator that can selectively modulate an incident light beam having a defined narrow spectral bandwidth to encode data thereon based on commands to an ON-state or an OFF-state of a micro-mirror. The micro-mirror array optical modulator can redirect light by diffraction and reflection to provide an output modulated light beam that exhibits a diffraction handedness dependent described by an arrangement of diffraction orders that depend in part on the narrow spectral bandwidth of light incident thereupon. An optical element has an optimized limiting aperture for defining portions of a modulated light beam that are blocked and remaining portions that are transmitted. An ON- state efficiency and an OFF-state contrast of an optically transmitted modulated light beam can depend on the diffraction handedness of the output modulated light beam relative to a size and a shape of the optimized limiting aperture.

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.
