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.

Light conditioning of direct view display for cinema

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.

Stereo image projection with high intra-frame contrast

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.

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.

Cinema light emitting screen and sound system

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.

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.

A radiant energy transfer panel is resized from an array of individually sealed segments by cutting the array along a cut line, thereby damaging some segments by breaking their seals. Other segments adjacent to the damaged segments are left intact. Each segment has two electrodes for power connection. Electrodes of the damaged segments remain electrically connected to electrodes of undamaged segments after cutting. An edge member may be positioned to overlap damaged segments and redirect light from undamaged segments to compensate for the damaged segments. In alternative embodiments, the edge member may be light-blocking. The radiant energy transfer panel may be an electroluminescent panel or a photovoltaic panel.

Methods for custom-fitting a radiant energy transfer panel

An apparatus () for radiant energy transfer has at least one radiant energy transfer panel () having a light-energy transfer surface () and a back surface (). The back surface has a panel electrode () for an electrical connection with the at least one radiant energy transfer panel. The panel electrode is conductively coupled to a first member of a separable flexible conductive fastener. A second member of the separable flexible conductive fastener has a power connection electrode. The power connection electrode is conductively coupled to a power device (). Mechanically engaging the first and second members of the separable flexible conductive fastener connects the panel electrode on the at least one radiant energy transfer panel to the power connection electrode.

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.
