1. An area-emissive light-emitting diode (LED) device, comprising:
- a) a substrate having an internal substrate surface, an external substrate surface opposite the internal substrate surface, and a substrate edge;
b) an array of area-emissive LED pixels formed on the internal substrate surface with an edge gap between the substrate edge and the LED pixel on the internal substrate surface nearest the substrate edge; and
c) a light-extraction structure formed in the edge gap and at least partially exterior to the LED pixels.
