1. A fluidic assembly carrier system for the mass transfer of micro-light emitting diodes (microLEDs) comprising:
a fluidic assembly carrier substrate with a planar top surface;
an array of trap sites formed on the carrier substrate top surface, each trap site configured as a recessed well with a planar bottom surface, to temporarily secure a fluidic deposition microLED;
microLEDs populating the carrier substrate wells, each microLED having a top surface interfacing with a corresponding well bottom surface, and a keel extending from a bottom surface;
a mass transfer stamp comprising:
a stamp substrate with a top surface; and,
an array of stamp substrate capture sites formed on the stamp substrate top surface, each capture site configured to temporarily accept a microLED keel of a corresponding microLED from a carrier substrate well.
