Abstract:
1. A tileable display panel, comprising: a screen layer upon which a unified image is projected from a backside; a display layer including a plurality of transmissive pixels to collectively project the unified image onto the backside of the screen layer, wherein 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; and an illumination layer to generate lamp light to illuminate a backside of the display layer, wherein 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, wherein the smaller transmission apertures of the transmissive pixels disposed within the perimeter region are sized to counterbalance the divergence of the lamp light incident upon the perimeter region such that image pixels projected onto the backside of the screen layer are substantially uniform in size from center to periphery across the screen layer, wherein the illumination layer includes: a diffuse radiator module centrally disposed on the illumination layer to emit diffuse lamp light to the central region of the display layer; and a light conditioning layer disposed between the diffuse radiator module and the display layer to collimate the diffuse lamp light prior to incidence upon the central region of the display layer.
