[News] Polar Light Technologies Demonstrates First Pyramidal-µLED Micro-Display Prototype

News Source: 

Polar Light Technologies AB today announced the successful fabrication of its first micro-display prototype built on the company’s proprietary pyramidal micro-LED (µLED). The milestone confirms the technology’s ability to integrate the pyramidal micro-LED frontplane onto a CMOS backplane.

The prototype pairs a bottom-up-grown Polar Light Technologies monochrome µLED front-plane with a high-performance SAPIEN CMOS back-plane. Precision flip-chip bonding was carried out by Finetech, achieving pixel-accurate alignment across the panel.

“This proof of concept shows that our pyramidal µLEDs can be hybridized to mainstream CMOS drivers creating a micro-display” said Ivan Martinovic, Co-Founder of Polar Light Technologies. “This achievement showcases our team’s incredible strength, and we thank our partners SAPIEN Semiconductors and Finetech for helping us validate the manufacturability of our platform.”

This latest achievement provides a path to monolithic RGB displays, based on the red, green, and blue µLEDs previously demonstrated using same material system.

Why It Matters

  • Monolithic RGB: Polar Light Technologies µLEDs, based on same material system, is paving the way for monolithic RGB displays.
  • Integration: The demo display is a stepping stone for Polar Light Technologies’ µLEDs to be integrated with CMOS backplane for novel opto products.
  • Pyramidal µLEDs manufactured bottom-up without etching, suitable for integration in VR/AR applications.
  • Sub-Lambertian emission: A naturally focused light lobe couples efficiently into waveguide, boosting brightness.
