A tileable display panel includes a screen layer, an illumination layer and a display layer. The screen layer is for displaying a unified image to a viewer. The illumination layer includes at least one light source emitting lamp light into a diffusing region of the illumination layer. The illumination layer also includes a plurality of emission apertures that are each configured to emit the lamp light from the diffusing region in a divergent projection beam. The display layer is disposed between the screen layer and the illumination layer. The display layer includes a plurality of pixelets corresponding to the plurality of emission apertures. The pixelets in the plurality of pixelets are positioned to be illuminated by the divergent projection beams from the corresponding emission apertures.

Multi-aperture illumination layer for tileable display

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.

Tileable display with pixel-tape

A display panel includes a carrier substrate, a system interconnect, and a plurality of display modules disposed across the carrier substrate. The display modules are each communicatively coupled to the system interconnect to each output a different portion of an overall image communicated via the system interconnect. Each of the display modules includes an array of direct emission display pixels and a module interconnect to couple the array of direct emission display pixels to the system interconnect. The array of direct emission display pixels of a given display module of the plurality of display modules is distinct and separate from the array of direct emission display pixels of other display modules of the plurality of display modules.

Display panel using direct emission pixel arrays

A rear projection screen includes an array of pin-hole apertures to pass display light incident from a first side of the rear projection screen through to a viewing side of the rear projection screen opposite the first side. An array of concentrator structures surrounds the pin-hole apertures and defines concentrating optical pathways. The concentrating optical pathways each have an input aperture for collecting the display light and an output defined by a corresponding one of the pin-hole apertures to emit the display light. The input apertures are larger than the pin-hole apertures.

Rear projection screen with pin-hole concentrator array

A projection screen includes a transparent substrate having a first side and a second side, an array of lenses disposed along the first side of the transparent substrate, a dark film disposed across the second side of the transparent substrate, an array of holes disposed through the dark film, and an array of diffusing spots each aligned with a corresponding one of the array of holes.

High contrast rear projection screen

A tileable display panel includes a screen layer, a display layer, and an illumination layer. The display layer includes a plurality of transmissive pixels to collectively project a unified image onto the backside of the screen layer. The transmissive pixels disposed within a perimeter region of the display layer have smaller transmission apertures than the transmissive pixels disposed within a central region of the display layer. The illumination layer generates lamp light to illuminate a backside of the display layer. The illumination layer is coupled to generate the lamp light incident on the backside of the display layer in the perimeter region with greater divergence than the lamp light incident on the backside of the display layer in the central region.

Seamless tileable display with peripheral magnification

A projection screen includes a transparent substrate having a front side and a backside, a dark film disposed across the front side of the transparent substrate, an array of holes disposed through the dark film, a diffusing layer disposed between the transparent substrate and the dark film, and an array of lenses disposed across the backside of the transparent substrate. The array of lenses are aligned to focus display light incident through the array of lenses towards the array of holes and the diffusing layer diffuses the display light for emission out the array of holes as diffuse display light.
