Abstract
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.
