Leti unveiled a new micro-LED display at Photonics West in January 2017. The 873 x 500 pixel display has a pixel pitch of 10 microns and is the fruit of four years of research and development.

The technological breakthrough is based on a patented self-aligned fabrication technique that requires one lithography step to create all of the electrical contacts and the micro-LED geometry and several damascene metallization steps. By eliminating certain alignment constraints, the pixel pitch is reduced, placing a pixel pitch of 7 microns within reach.
High-resolution micro-displays can be used in mobile augmented and virtual reality systems, for example.
