Abstract

Electrically pixelated luminescent devices, methods for forming electrically pixelated luminescent devices, systems including electrically pixelated luminescent devices, and methods for using electrically pixelated luminescent devices are described. More specifically, electrically pixelated luminescent devices that have inner and outer semiconductor layers and a continuous light emitting region, as well as individually addressable electrodes are described.
