1. An encapsulated emissive element for selective fluidic assembly comprising:
a micro-light emitting diode (micro-LED) having a closed perimeter shape, as viewed from a horizontal plane top-down perspective, comprising a top surface, a bottom surface with a first length in the horizontal plane, sidewall surfaces with a first thickness between the micro-LED top and bottom surfaces less than the first length, and a pair of electrical contacts; and,
a fluidic assembly key without electrical contacts, exposing the micro-LED electrical contacts and a second length of micro-LED bottom surface, where the second length is greater than the first thickness, while at least partially encapsulating the micro-LED to form a closed perimeter shape, as viewed from the horizontal plane top-down perspective, different than the micro-LED closed perimeter shape.
