Claim 2:
3. The method of claim 2, further comprising:
providing a third substrate having a third surface region;
forming a third release material overlying the third substrate;
forming a third epitaxial material overlying the third surface region, the third epitaxial material comprising at least an n-type gallium, indium, phosphorous, nitrogen, aluminum, or arsenic containing region; a gallium, indium, phosphorous, nitrogen, aluminum, or arsenic containing light emitting region configured to emit electromagnetic radiation at a third red wavelength; and a p-type gallium, indium, phosphorous, nitrogen, aluminum, or arsenic containing region;
patterning the third epitaxial material and forming mesas to form a third plurality of dice arranged in a third array, each die corresponding to at least one light emitting diode device and being arranged by a fifth pitch between adjacent die in the third array;
forming a third interface region overlying the third epitaxial material, the third interface region comprising a metal, a semiconductor, a dielectric, an oxide, a glass, or a polymer;
subjecting the third release material to a third energy source to fully or partially remove the third release material, the third release material disposed between the third substrate and the third epitaxial material;
bonding the third interface region to the at least one carrier wafer to form a third bonded structure, while maintaining the third release material fully or partially removed from the third bonded structure;
releasing at least a third fraction of the third plurality of dice provided on the third substrate to transfer the third fraction of the third plurality of dice to the at least one carrier wafer wherein each pair of the transferred dice is configured with a sixth pitch between each pair of the transferred dice, the sixth pitch being equal to or greater than the fifth pitch; and
processing the at least one carrier wafer with at least the first fraction of the first plurality of dice, the second fraction of the second plurality of dice, and the third fraction of the third plurality of dice to form the light emitting diode based display panel device operable at least at the first blue wavelength, the second green wavelength, and the third red wavelength, the third red wavelength having a range of about 620 nm to 700 nm.
