1. A method of populating a receiver substrate, the method comprising the steps of:
preparing a plurality of microdevices on one or more donor substrates;
transferring the plurality of microdevices from the one or more donor substrates to a first cartridge substrate, wherein the first cartridge includes three different types of micro devices and a spare micro device or a void area, the plurality of microdevices are arranged in arrays;
selecting at least one set of microdevices in the first cartridge substrate associated with a set of contact pads in the receiver substrate;
identifying a number of defective microdevices in the at least one set of microdevices;
correcting the defective microdevices if the number of defective microdevices in the set is more than a set threshold value; and
aligning and transferring the selected set of microdevices on the first cartridge substrate to corresponding contact pads on the receiver substrate.
