    Abstract: A prescriptive see-through eyepiece includes a meniscus lens body and an optical combiner. The meniscus lens body has an external scene side with a convex curvature and an eye-ward side with a concave curvature. The optical combiner is disposed within the meniscus lens body to combine image light incident through the eye-ward side with external scene light incident through the external scene side into a combined image. The optical combiner is partially reflective and imparts substantially no lensing power to the external scene light passing through. The optical combiner along with the concave curvature of the eye-ward side are configured to impart prescriptive lensing to the image light while the convex curvature of the external scene side and the concave curvature of the eye-ward side are configured to impart the prescriptive lensing to the external scene light.

    Abstract: A multi-layer projection screen includes a transparent substrate having first and second sides, a stray light rejection layer, and a lens array. The stray light rejection layer is disposed across the first side of the transparent substrate. The stray light rejection layer includes an array of pillar structures, wherein each pillar structure of the array of pillar structures includes an entrance aperture, an exit aperture, a substantially transparent pathway extending from the entrance aperture to the exit aperture, and an opaque side wall surrounding the transparent pathway. The lens array is disposed across the second side of the transparent substrate and optically aligned to the array of pillar structures. The stray light rejection layer blocks display light received from the lens array having an oblique trajectory that is greater than a threshold angle from a normal of the second side of the transparent substrate.

    Abstract: A tileable display panel includes an array of display pixels including central display pixels near a center of the array having a center pixel pitch and perimeter display pixels along a perimeter of the array. A perimeter region surrounds the array. The perimeter region includes a first side that is joinable to a second side of another instance of the tileable display panel to form a multi-panel display. The perimeter region has a width that is greater than at least half the center pixel pitch such that a gap between adjacent perimeter display pixels of the tileable display panel and the other instance of the tileable display panel when forming the multi-panel display is greater than the center pixel pitch. The gap is visually masked by increasing a characteristic of the perimeter display pixels adjacent to the gap relative to the same characteristic of the central display pixels.

    Abstract: A display apparatus including a screen layer for displaying a unified image to a viewer and an illumination layer having an array of light sources. Each light source emits a light beam. An array of optical elements, each coupled to a corresponding light source in the array of light sources, is disposed between the screen layer and the illumination layer. The display layer includes a matrix of pixlets and a spacing region disposed between the pixlets in the matrix, wherein the array of light sources emit their light beams through the array of optical elements, wherein each optical element is configured to shape the received light beam into a divergent projection beam having a limited angular spread to project sub-images displayed by the pixlets as magnified sub-images on the backside of the screen layer, the magnified sub-images to combine to form the unified image that is substantially seamless.

    Abstract: A projection screen includes a transparent substrate having a first side and a second side, a first optically clear adhesive (“OCA”) layer disposed across the first side of the transparent substrate, a first two-dimensional (“2D”) matrix of clear beads partially embedded into the first OCA layer, and a dark layer disposed across the first OCA layer filling in exposed gaps between the clear beads to block and absorb light incident upon the exposed gaps between the clear beads. The clear beads form optical paths through the dark layer.
