Polar Light Technologies
Polar Light Technologies is a Swedish microLED company spun out of Linköping University. The company has developed a proprietary bottom-up manufacturing technology in which pyramidal InGaN/GaN microLEDs are grown directly by MOCVD, instead of being defined through conventional etching.
PLT says that its bottom-up approach avoids the sidewall damage and efficiency losses associated with etched microLEDs, particularly as pixel dimensions are reduced, and so provides a route to highly efficient, densely integrated microLED arrays and monolithic multi-colour devices.
Polar Light Technologies develops microLED components, display modules and development platforms for microdisplays, optical systems and larger-area display applications.
In 2026, the company raised over 5 million Euro as it gets ready to launch its first products. Also in 2026, the company produced a series of sub 500 nanometer InGaN LEDs, the smallest LEDs ever demonstrated.

Polar Light Technologies produces its first microLED array at its new VTT Pilot Line
Polar Light Technologies announced that it has produced its first MicroLEDs via its Pilot Line at VTT Technical Research Centre Finland. The company says that its process flow transfer from the laboratory to the VTT pilot line is ahead of schedule - "demonstrating the advantages of pyramidal MicroLEDs and selected area growth".
The next step for PLT is to focus on homogeneity, yield and the integration of the MicroLEDs to a CMOS backplane. The company's goal is to produce a complete microLED microdisplay in the pilot line, and towards that it will develop bonding and integration of the MicroLEDs frontplane onto the CMOS backplane.
Innovations Festival: Free online MicroLED and next‑generation display event – secure your place now!
MicroLED-Info, together with TechBlick, invites the community to join the upcoming Innovations Festival, a free-to-attend online event taking place on July 10, 2026 (1300–20:00 CET).
The event will bring together engineers, researchers, entrepreneurs, display makers, and industry stakeholders working across MicroLEDs, AR/VR, advanced displays, and next-generation electronics. MicroLED technologies will be a central theme, featured alongside adjacent developments that are critical for future display ecosystems, from advanced materials to novel integration and manufacturing approaches.
Polar Light Technologies to setup a pilot line at VTT
Polar Light Technologies announced that it has signed its first Pilot Line agreement with VTT Technical Research Centre of Finland.
Polar Light has already begun its process flow transfer from the laboratory to VTT's Pilot Line. The Pilot Line will cover the full manufacturing flow required for Polar Light's first microLED product, which will help the company to accelerate the validation, scaling and product readiness.
The MicroLED Association to Host Pavilion and Annual Dinner at SID DisplayWeek 2026
The MicroLED Industry Association is excited to announce its activities for SID DisplayWeek 2026, taking place this May in Los Angeles, California. This year marks an important step forward for our community: in addition to our traditional Annual MicroLED Association Dinner, we will for the first time host a dedicated MicroLED Association Pavilion on the exhibition floor.
The Pavilion will feature six of our leading member companies—ADEIA, CEA-Leti, ETRI, Polar Light, QustomDot, and WEVE—each showcasing their latest innovations and technologies advancing the microLED industry. Visitors will have the opportunity to explore a diverse range of new solutions spanning materials, processes, equipment, and system integration, all driving the next generation of display performance.
Polar Light and Finetech awarded a 1.1 million Euro project to develop dual-color microLED microdisplays
Pyramidical GaN microLED developer Polar Light Technologies has been awarded an EU Eurostars grant to develop a dual-color microLED microdisplay prototype deposited using the company's bottom-up mask-based deposition process.
The project, called 2ndGenMicroLED, will run for 18-month project, and has a total budget of 1.1 million Euro.
Polar Light demonstrates 500 nm and smaller microLED devices
Pyramidical GaN microLED developer Polar Light Technologies announced that it has produced a series of nano-scale InGaN LEDs, measuring 500 nanometers and smaller. The company says these are the smallest LEDs ever demonstrated.
The microLED devices have been produced using the company' monolithic bottom-up mask-based process, that has been now demonstrated to scale to significantly smaller dimensions without compromising performance or efficiency.
Polar Light raises over 5 million Euro as it gets ready to launch its first products
Pyramidical GaN microLED developer Polar Light Technologies announced that it has successfully closed a new financing round, raising over 5 million Euros. This brings the total funding today to 13 million Euros.
This new round was by J2L Holding AB, with participation from STOAF, Almi Invest and Butterfly Ventures. Polar Light says that this new funding will give it the runway to bring its first products to market.

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.

Polar Light Technologies fabricated its first microLED microdisplay, using its red pyramidal microLEDs
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.
