Polar Light unveils the first nanoLEDs
Polar Light Technologies AB, a Swedish microLED company, has unveiled a breakthrough at SPIE Photonics West 2026, with the first series of nano-scale LEDs.
The company says it's achievement illustrates the extraordinary flexibility of its patented pyramidal architecture, developed without requiring the traditional etching process.
Over the last several months, Polar Light has produced a series of electrically excited InGaN nanoLEDs, measuring 500nm and smaller, which are built using the same monolithic architecture as Polar Light's existing microLED platform. This new process makes it possible to scale the technology to significantly smaller dimensions without compromising performance or efficiency, according to the company.
"Reaching nanoLED scale without sacrificing LED performance or production capability is a major milestone for the industry," said Oskar Fajerson, CEO, Polar Light Technologies. "NanoLEDs, in combination with our roadmap toward monolithic RGB, will enable the next generation of ultra‑small, monolithic full‑colour displays."
MicroLED is widely regarded as the next display technology due to its unparalleled brightness and low power consumption, making it possible to create whole new categories of display types for a wide variety of novel use cases.
In spring 2025, Polar Light demonstrated its first public prototype at Display Week. In January 2026, Polar Light announced a new €5 million+ funding round that will enable the company to bring its first products to market in late 2026.
