Abstract

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.
