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.

A display panel includes an array of display pixels to output an image. The array of display pixels includes a central pixel region and a perimeter pixel region. The central pixel region includes central pixel units each having three different colored sub-pixels. The different colored sub-pixels of the central pixel units are organized according to a central layout pattern that repeats across the central pixel region. The perimeter pixel region is disposed along a perimeter of the central pixel region and includes perimeter pixel units that increase a brightness of the image along edges of the central pixel region to mask gaps around the array of display pixels when tiling the array of display pixels with other arrays of display pixels.

A multi-layer projection screen includes a stray light rejection layer and a lens array. 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 pathway extending from the entrance aperture to the exit aperture, and a side wall surrounding the pathway. The lens array is 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 first trajectory.

High contrast projection screen with stray light rejection

Techniques and mechanisms to provide for improved image display in an area of overlapping projections. In an embodiment, a multi-layer projection screen comprises light sources and collimation structures each disposed over a corresponding one of such light sources. A first collimation structure disposed over a first light source collimates first light from the first light source. The first collimation structure further receives and redirects second light from a second light source disposed under a second collimation structure that adjoins the first collimation structure. In another embodiment, the first collimation structure redirects the other light from the second light source away from the direction of collimation of the first light. A stray light rejection layer of the multi-layer projection screen passes a majority of the first light for inclusion as part of a projected image, and prevents a majority of the second light from inclusion in the projected image.

Apparatus, system and method for mitigating contrast artifacts at an overlap region of a projected image

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.

Optical configurations in a tileable display apparatus

A display tile for arranging with other display tiles to form a multi-tile display includes display pixels in an active display area, pixel tape sections, and a transparent layer. The pixel tape sections surround the display pixels. Each pixel tape section overlaps an adjacent pixel tape section and is overlapped by another adjacent pixel tape section disposed opposite the adjacent pixel tape section. Each pixel tape section includes a pixel array. The transparent layer is disposed over the display pixels and the pixel arrays of the pixel tape sections. The display pixels and the pixel arrays are arranged to display an overall image of the display tile.

A multi-domain liquid crystal pixel array includes two substrate layers and liquid crystal disposed between the two substrate layers. The multi-domain liquid crystal pixel array also includes at least one alignment layer having four or more alignment zones across the multi-domain liquid crystal pixel array. Each alignment zone has a different pre-tilt liquid crystal orientation than the other alignment zones. The alignment zones are configured to generate divergent image light with respect to a center of the multi-domain liquid crystal pixel array.

Multi-domain pixel array

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.

Masking mechanical separations between tiled display panels

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.

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.
