µLED Display Architectures for AR Glasses: Key Platforms, Concepts & Performance Drivers

Micro-LEDs are unlocking the next generation of bright, efficient, and ultra-compact displays for augmented reality (AR).
We present a complete technology pathway to achieve the smallest pixel pitches without compromising performance.
Leveraging advanced device simulations, optical engineering, high-precision CMOS integration, and optimized AR optics, we address key challenges including surface recombination in red emitters, improved light extraction and light coupling in DPA-Optics, and system-level efficiency.
As the “north star” for µLED AR displays, we compare color mixing of monochrome µLEDs with monolithic multicolor RGB-µLED architectures for AR glasses, revealing trade-offs in pixel pitch, efficiency, and form factor.
This holistic optimization approach paves the way for ultra-fine-pitch, high-performance, full-color µLED displays that bring AR glasses closer to seamless, real-world deployment
