Polar Light Technologies – Building the Next Generation of MicroLED Displays
Polar Light Technologies (PLT) is a Swedish semiconductor company developing a new generation of MicroLED displays based on a unique pyramid-shaped GaN structure. We spoke with Oskar Fajerson, CEO of Polar Light Technologies, about their approach, progress, and vision for the industry.

Can you introduce your company and technology?
Polar Light Technologies was founded with a clear ambition: to make microLED monolithic color display. Our proprietary technology is based on a pyramid-shaped GaN structure. This structure has several benefits that allows us to build a monolithic color display using microLEDs that can be less than 1 µm.
Why did you join the MicroLED Association and what do you hope to achieve?
The MicroLED Association brings together the key innovators and ecosystem players that are defining the future of this technology. For us, joining was a natural step. We want to contribute to shaping the standards and best practices that will help MicroLEDs mature faster as an industry.
At the same time, it’s a great platform to exchange insights, align on challenges, and connect with partners and customers. Collaboration is essential — no single company will solve the scaling challenge alone.
What has been your biggest challenge and success to date?
The biggest challenge has been to convince the market that the pyramidal structures will solve many of the current microLED challenges.
Our greatest success so far has been the achievement using InGaN quantum wells as the red emitters and the demonstration of our well-functioning MicroLED display, which proves that the pyramidal structures can be connected and integrated with a CMOS backplane.
Can you detail your latest prototype or demonstration?
The latest demonstration was the fully working MicroLED display - and importantly, not just a single functional unit, but multiple units.

How do you see MicroLEDs changing the display industry in the next 5–10 years?
MicroLEDs are on a trajectory to become the leading display technology of the next decade. They combine the vivid color and contrast of OLEDs with the brightness, robustness, and efficiency of inorganic LEDs.
In the next five to ten years, I expect MicroLEDs to move beyond premium TVs and AR devices, into automotive, defense, and industrial visualization systems. At that point, we won’t just be talking about displays — we’ll be talking about light engines, integrated directly into optics, sensors, and environments.
Thank you Oskar, good luck to you and Polar Light Technologies!
