Polar Light Technologies Demonstrates First Pyramidal-µLED Micro-Display Prototype

Polar Light Technologies AB announced the 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 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.
