A mechanism for deterring dark spot propagation by dividing the active emitting area, i.e., pixel, of each light emitting device into sub-regions that are separated by a dielectric barrier. This division prevents spreading of one affected region to adjacent current carrying regions. A side benefit of the division is improved out-coupling of light from the active emitting area of the light emitting device because the morphology resulting from the incorporation of the dielectric barrier can be configured to increase the externally radiated, and thereby collectable, portion of the generated light.
