摘要

Abstract

The development of GaN-based Micro-LED arrays achieving brightnesses exceeding 10

nits and high-density micro-displays with up to 1080×780 pixels marks a true breakthrough in the field. This breakthrough is a result of mastering a combination of long-standing challenges comprising wafer-scale high-quality epitaxial growth

sidewall passivation

efficient photon extraction

and elegant bonding technologies

and promises significant advantages for augmented and virtual reality devices

wearables

and next-generation consumer electronics.
