SID Display Week (DW) 2025 is coming to San Jose, CA, May 11–16. My last two articles discussed LCOS technology I saw at DW 2024 and MicroLEDs for AR at DW 2024. This article will concentrate on Micro-OLED (also known as OLEDs on Silicon), which could be used in optics-see-through (OST) Augmented Reality (AR) or Virtual Reality (VR) headsets.
