MicroLED devices with integrated micro-lenses


MICLEDI Microdisplays, a leading developer of microLED displays for augmented reality (AR) glasses, announced the industry’s first microLED devices with integrated micro-lenses for pixel-level beam shaping , manufactured in the company’s proprietary 300mm manufacturing flow.

The new family of microLED devices offers multiple benefits for waveguide AR glasses, including:

  • Improved energy efficiency – by focusing the light into the targeted waveguide cone
  • Optimal waveguide coupling – providing additional flexibility for AR system integration and image quality enhancement via controllable color dispersion compensation
  • Pixel scaling at a pitch of less than 3.0 microns – with highly repeatable beam shape performance

Samples and test kits of blue and green microLED arrays, as well as blue arrays with micro-lenses were delivered to customers this summer with red microLEDs coming in Q422. Available for both microLED device evaluation and display integration with waveguides, customers will see FHD display blocks and a variety of other microLED structures with mesa sizes up to to 0.5 microns, and with micro-lens reference designs by MICLEDI.

According to Sean Lord, CEO of MICLEDI Microdisplays, “We are extremely excited to reach this milestone with customer-grade samples of each of our RGB arrays. Customers are asking for these improved devices. With micro-lenses, we are pleased to point out that one of the hottest demands in the field, the efficiency of the “AR” pitch microLED wall socket will be at best-in-class levels. In parallel, we are working on our first RGB modules and exploring polychromatic RGB integration approaches.

MICLEDI also pioneered the development of a modeling platform for customizing micro lenses. The platform will be available for AR customers to evaluate new technology in simulations and design their own micro-lenses for specific waveguide configurations. These can then be prototyped using MICLEDI’s manufacturing capabilities.

“The integration of micro-lenses into a tight-pitch microLED device is a culmination of MICLEDI’s unique fabrication capabilities using 300mm wafer fabrication equipment. High-quality beam shaping requires extreme precision and nanoscale stacking accuracy that can only be achieved in a 300mm wafer fab,” said Dr. Soeren Steudel, co- founder and CTO of MICLEDI Microdisplays.

Later this month, MICLEDI will be present at the SPIE Optics + Photonics conference in San Diego. Stop at table #551.

About MICLEDI micro-displays

MICLEDI Microdisplays is a fabless developer of microLED display modules for the augmented reality (AR) market. The company was spun off from IMEC, a highly respected Belgian R&D center, in 2019. MICLEDI’s technology is based on an innovative combination of III/V material processing, 3D integration and silicon-based processing of 300 mm combined with a proprietary ASIC to provide a compact, self-contained monolithic AR display with high image quality and power efficiency.
