How it works
Each pixel is formed by self-emissive micro-LEDs, eliminating backlights and filters; this yields high brightness and contrast at low power. Manufacturing requires precisely transferring millions of microdies onto a substrate.
Problem solved
How to achieve bright, power-efficient and durable displays small enough for AR glasses?
