Claim 0:
1. A transfer process comprising:
picking up a first group of light emitting diodes (LEDs) from a first donor substrate with a micro pick up array comprising a plurality of clusters of transfer heads, wherein adjacent transfer heads within a row of transfer heads within a cluster are separated by an intra-cluster spacing, and adjacent clusters within a row of clusters are separated by an inter-cluster spacing that is greater than the intra-cluster spacing;
positioning the micro pick up array over a first location of a display substrate;
placing a first LED of the first group of LEDs from each cluster onto the display substrate;
positioning the micro pick up array over a second location of the display substrate; and
placing a second LED of the first group of LEDs from each cluster onto the display substrate.
