Pyramidical GaN microLED developer Polar Light Technologies announced that it has fabricated its first microLED microdisplay prototype, using its pyramidal micro-LED devices. The company says that this important milestone confirms the possibility of integrating the pyramidal micro-LED frontplane onto a CMOS backplane.
The prototype uses monochrome (red, likely 625 nm) microLEDs, built on high-performance Sapien CMOS back-plane. The flip-chip bonding was carried out by Finetech.
While this display is monochrome, the company's platform can be used to produce red, green and blue microLEDs using the same material system.
Last month Polar Light has successfully closed a fully subscribed funding round $3.4 million, from both existing and new investors. The company aims to bring its microLED technology to market in 2026.
Polar Light's technology is used to produce microLEDs using a non-etching bottom-up approach using a patterned mask. Towards the end of 2024, the company announced that it has managed to produce red (625 nm) microLEDs, and has thus managed to produce based on its non-etching bottom-up platform. The company now has demonstrated the production of red, green and blue pyramidal microLEDs using the same material compound.
