Abstract
Micro light-emitting diode (LED) displays, and fabrication and assembly of micro LED displays, are described. In an example, a pixel element for a micro-light emitting diode (LED) display panel includes a blue color nanowire or nanopyramid LED above a first nucleation layer above a substrate, the blue color nanowire or nanopyramid LED including a first GaN core. A green color nanowire or nanopyramid LED is above a second nucleation layer above the substrate, the green color nanowire or nanopyramid LED including a second GaN core. A red color nanowire or nanopyramid LED is above a third nucleation layer above the substrate, the red color nanowire or nanopyramid LED including a GaInP core.
