India, Sept. 22 -- ​​​The Propolys project, conducted at CEA-Leti between 2021 and 2025, has successfully validated several key technology building blocks for the development of full-color micro-LED displays. Supported by Carnot funding, the project will contribute to future augmented reality applications.

At the heart of augmented reality glasses and headsets are micro-displays measuring barely a centimeter across. These tiny displays can integrate millions of micro-LEDs, light sources only a few micrometers in size.

In particular, gallium nitride (GaN)-based micro-LEDs offer significantly higher brightness than current OLED technologies. This is essential for displaying information overlaid on glasses, even in bright...
