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 (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.

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： Filter glasses for use by an observer of a stereoscopic digital display system that displays stereoscopic images including first-eye images and second-eye images. The filter glasses include a first-eye filter that substantially transmits light from the first-eye images and blocks light from the second-eye images, and a second-eye filter that substantially transmits light from the second-eye images and blocks light from the second-eye images. A frame is used to position the first-eye filter in front of the observer's first eye and to position the second-eye filter in front of the observer's second eye, such that the front surfaces of the filters are oriented at a tilt angle of at least 5 degrees relative to vertical so that light from the display surface that is reflected from the first-eye filter and the second-eye filter is directed over the heads of other observers that are seated in front of the observer.

摘要： 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.

摘要： 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.

摘要： A stereo viewing device comprises a first lens comprising a first lens filter, and a second lens comprising a second lens filter. The first lens filter comprises a first set of light absorbing dyes that define a first set of rejection bands. The first set of light absorbing dyes comprises at least a first polymethine dye. The second lens filter comprises a second set of light absorbing dyes that define a second set of rejection bands different from the first set of rejection bands. The second set of light absorbing dyes comprises at least a second polymethine dye.

摘要： 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.

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： Screen vibration systems are provided that can vibrate theatre screens 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 screen, a permanent magnet mounted to the screen, and a magnetic source positioned with respect to the permanent magnet. The screen is moveable in response to a changing magnetic field from the magnetic source.

摘要： A cinema screen can be vibrated by a screen vibrator assembly. A screen vibrator assembly can include a vibrator, a mount bracket, and an isolation device. The vibrator can be positioned to generate a vibration for vibrating a cinema screen. The mount bracket is configured to be coupled to a screen support structure of the cinema screen. The isolation device is configured to couple the vibrator to the mount bracket to isolate the mount bracket from the vibration.
