By a News Reporter-Staff News Editor at Journal of Engineering -- A patent by the inventors Candry, Patrick (Kuurne, BE); Maximus, Bart (Kuurne, BE); Maes, Dirk (Kuurne, BE), filed on October 27, 2015, was published online on August 8, 2017, according to news reporting originating from Alexandria, Virginia, by VerticalNews correspondents.

Patent number 9726968 is assigned to Barco, Inc. (Rancho Cordova, CA).

The following quote was obtained by the news editors from the background information supplied by the inventors: "Field

"The present disclosure generally relates to projection display systems and methods having one or more projection displays arranged for immersive viewing of an image and includes systems and methods to enhance at least the dynamic range and the contrast ratio of the image based at least in part on selective incident angle reflection of one or more projection screens.

"Description of Related Art

"Digital cinema servers and projectors receive digital content for projection in a theater or other venue. The content can be packaged in one or more digital files for delivery and storage on a media server. The media server can then extract the digital content from the one or more digital files for display using one or more projectors. In some cases, the content can be 3D video projected onto a screen where slightly different visual content is projected for simultaneous observation in the right and left eyes of a viewer to create the illusion of depth. A multi-projection system can be used to display video on a plurality of screens in a venue, such as in a theater or auditorium, to facilitate an immersive experience for the viewer."

In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventors' summary information for this patent: "Example embodiments described herein have innovative features, no single one of which is indispensable or solely responsible for their desirable attributes. Without limiting the scope of the claims, some of the advantageous features will now be summarized.

"An immersive display system can include a plurality of projection systems arranged to provide immersive viewing of video. Such an immersive display system can include a plurality of projector systems that each projects video configured to complement one another to provide an immersive viewing experience for viewers. Each projector system can be configured to project its video onto a projection surface placed around an audience. In this way, the audience can experience a sense of immersion into the environment depicted in the video. Video provided by the plurality of projector systems may be projected on the plurality of projection surfaces creating a unified video presentation. Such immersive display systems are capable of generating audiovisual presentations with a relatively high level of realism due at least in part to the quality of the images provided on the plurality of projection surfaces.

"However, having multiple projection surfaces can result in light being reflected from a first projection surface to a second projection surface and then to the viewer. This light mixes with the light reflected directly from the first projection surface to the viewer. Such mixing of light on the plurality of projection surfaces can reduce the contrast ratio and/or dynamic range of the projection surfaces, thereby diminishing the quality of the images provided in the immersive display system. This mixing of light can be referred to as cross-talk or cross-reflection and can be a challenge in immersive display systems. This challenge may be even more difficult to overcome for immersive display systems designed for a relatively large group of people, such as in a movie theater, due at least in part to the wide range of viewing angles of the viewers in the audience.

"Accordingly, systems and methods are provided herein for immersive display systems that include a plurality of projection surfaces (e.g., screens) that are usable over a wide range of viewing angles and for which a decrease in the contrast ratio and/or dynamic range caused by cross-talk or cross-reflection between different parts of the plurality of projection surfaces is substantially reduced. In some embodiments, the systems and methods disclosed herein provide relatively high-contrast, high-dynamic range immersive viewing of images using two or more curved or plane screens where the cross-reflections are substantially suppressed by selectively scattering and absorbing light through a multi-layer structure that scatters light incident within a tailored range of incident angles and that absorbs light incident outside the tailored range of incident angles. This can be accomplished through a combination of light polarization layers, polarization rotation layers, reflection layers or structures, and non-polarizing light scattering materials in combination with arrays of micro-lenses and/or micro-mirrors.

"In a first aspect, a screen is provided for use in an immersive display system, the screen including an array of micro-lenses, individual lenses in the array of micro-lenses having a width D, a layer of light polarization material, a polarization rotation layer, a light reflection layer, and a section of non-polarizing light scattering material for individual micro-lenses in the array of micro-lenses. The section of non-polarizing light scattering material has a width that is less than the width D. In use, light from a projector associated with the screen is substantially scattered by the non-polarizing light scattering material and light from a projector associated with a different screen in the immersive display system is substantially absorbed by the polarization layer.

"In some embodiments of the first aspect, the array of micro-lenses comprises spherical micro-lenses. In a further embodiment, the array of micro-lenses further comprises aspherical micro-lenses.

"In some embodiments of the first aspect, the array of micro-lenses comprises cylindrical micro-lenses. In a further embodiment, the array of micro-lenses further comprises cylindrical micro-lenses having an aspheric shape in a plane perpendicular to a longitudinal axis of the cylindrical micro-lens. In a further embodiment, each section of non-polarizing light scattering material forms a strip parallel to a longitudinal axis of the associated cylindrical micro-lens.

"In some embodiments of the first aspect, the screen further includes perforations positioned at transitions between micro-lenses in the array of micro-lenses. In a further embodiment, the perforations in the array of perforations are located at corners between spherical micro-lenses. In a further embodiment, the perforations in the array of perforations are located at edges between cylindrical micro-lenses. In a further embodiment, the perforations in the array of perforations are equidistant along a straight line. In a further embodiment, the perforations in the array of perforations are circular.

"In a second aspect, a screen is provided for use in an immersive display system. The screen includes an array of micro-mirrors, individual mirrors in the array of micro-mirrors having a width D, a polarization rotation layer, a linear polarization layer, and a section of non-polarizing light scattering material for individual micro-mirrors in the array of micro-mirrors. The section of non-polarizing light scattering material has a width that is less than the width D. In use, light from a projector associated with the screen is substantially scattered by the non-polarizing light scattering material and light from a projector associated with a different screen in the immersive display system is substantially absorbed by the polarization layer.

"In some embodiments of the second aspect, the array of micro-mirrors comprises spherical micro-mirrors. In a further embodiment, the array of micro-mirrors further comprises aspherical micro-mirrors.

"In some embodiments of the second aspect, the array of micro-mirrors comprises cylindrical micro-mirrors. In a further embodiment, each section of non-polarizing light scattering material forms a strip parallel to a longitudinal axis of the associated cylindrical micro-mirror. In some embodiments of the second aspect, the screen further includes perforations positioned at transitions between micro-mirrors in the array of micro-mirrors.

"In a third aspect, an immersive display system is provided that includes one or more of the screens of the first or second aspect. In some embodiments of the third aspect, the one or more screens are curved."
