The company’s first micro-display prototype proves the ability to integrate its µLED architecture into working products.

Linköping, Sweden – May 5th, 2025 – 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.

About Polar Light Technologies
Polar Light Technologies pioneers a patented, bottom-up process that grows pyramidal micro-LEDs atom layer by atom layer, eliminating destructive etch steps conventional methods require. The result: record-small pixels,superior brightness and efficiency, and a manufacturing flow that scales cleanly to high-volume wafers. Spun out of Professor Per-Olof Holtz’s research at Linköping University with support from the Swedish Foundation for Strategic Research (SFF) and Sweden’s innovation agency Vinnova, Polar Light Technologies supplies wafer-level RGB micro-LED arrays that power the next generation of ultra-compact displays.
