A bright future for micro-LED displays

Light Sci Appl. 2024 Dec 6;13(1):317. doi: 10.1038/s41377-024-01683-z.

Abstract

The development of GaN-based Micro-LED arrays achieving brightnesses exceeding 107 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.
