Claim 1:
2. The method of claim 1, further comprising:
providing a second substrate having a second surface region;
forming a second release material overlying the second substrate;
forming a second epitaxial material overlying the second surface region, the second epitaxial material comprising at least an n-type gallium and nitrogen containing region, a light emitting gallium and nitrogen containing region configured to emit electromagnetic radiation at a second green wavelength, and a p-type gallium and nitrogen containing region;
patterning the second epitaxial material and forming mesas to form a second plurality of dice arranged in a second array, each die corresponding to at least one light emitting diode device and being arranged by a third pitch between adjacent die in the second array;
forming a second interface region overlying the second epitaxial material, the second interface region comprising a metal, a semiconductor, a dielectric, an oxide, a glass, or a polymer;
subjecting the second release material to a second energy source to completely or partially remove the second release material, the second release material disposed between the second substrate and the second epitaxial material;
bonding the second interface region to the at least one carrier wafer to form a second bonded structure, while maintaining the second release material completely or partially removed from the second bonded structure;
releasing at least a second fraction of the second plurality of dice provided on the second substrate to transfer the second fraction of the second plurality of dice to the at least one carrier wafer wherein each pair of the transferred dice is configured with a fourth pitch between each pair of the transferred dice, the fourth pitch being equal to or greater than the third pitch; and
processing the at least one carrier wafer with at least the first fraction of the first plurality of dice and the second fraction of the second plurality of dice to form the light emitting diode based display panel device operable at least at the first blue wavelength and at the second green wavelength, the second green wavelength having a range of about 500 nm to 550 nm.
