摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Screen vibration systems are provided that can vibrate theatre screens using acoustical, electromagnetic, or another type of energy while reducing the presence of image artifacts that may otherwise be visible as result of vibrating the screen. In one example of a screen vibration system, the system includes a controller and an electromechanical acoustical actuator with an open baffle. The electromechanical acoustical actuator can be uncoupled from the screen in an operational setup. The controller can provide a signal to the electromechanical acoustical actuator for causing the electromechanical acoustical actuator to output energy to displace air that is (i) in front of the electromechanical acoustical actuator and (ii) between the electromechanical acoustical actuator and the screen. The open baffle can prevent displaced air behind the electromechanical acoustical actuator from affecting the screen

摘要： 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.

摘要： 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.
