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 th...

In a remarkable breakthrough in their research, Polar Light Technologies has achieved red light of 625 nm based on the company’s non-etching bottom-up concept. This means Polar Light Technologies have reached red, green, and blue pyramidal microLEDs using the same material compound. The pyramidal design has the ability to be manufacturable while maintaining excellent microLED performance, laying the foundation for monolithic RGB displays. This milestone marks the culmination of years of rigorous research and development, truly enabling spatial computing and ...

Polar Light Technologies, a leader in the development of microLED, is excited to announce a partnership with Finetech, a globally recognized supplier for sub-micron and high-accuracy die bonding solutions. The collaboration has already yielded significant advancements in micro-LED technologies for next generation AR, HUD and HMD applications. Polar Light Technologies has introduced a major breakthrough in display technology by creating novel GaN pyramidal microLEDs that are directly bonded to Indium pads on a silicon chip. This new method, where LEDs are bui...
