"AlInP/ GaInP quantum-well energy barrier confines electrons/ holes preventing energy leakage from smaller pixels... picking/ placing individual LEDs prone to alignment errors/ defects at high resolutions, overcome using low-temperature monolithic 3D integration, stacking LED layers directly onto driving circuitry... monolithic 3D integration on silicon... high quantum efficiency, minimal power consumption... AR/ VR smart glasses creating reality-like immersion, brightness/ longevity for heads-up displays"
