Linköping, Sweden – january 6, 2025 – swedish deep-tech company Polar Light Technologies is celebrating a major breakthrough in microLED technology: the prosperous growth of red pyramidal microLEDs. This significant achievement paves the way for truly monolithic RGB displays with unparalleled performance, opening up exciting possibilities for the future of visual technology.
Red Light Emission: A Long-Standing Challenge in MicroLED technology
While blue and green microLEDs have been commercially available for some time, efficiently producing red light emission has proven to be a persistent challenge in the field. Traditional methods often involve compromises in efficiency,manufacturability,or require the use of different material systems.
“Our pursuit of polar Light’s innovative pyramidal LED concept has been focused on overcoming these challenges without sacrificing performance,” explained Lisa Rullik, CTO of Polar Light Technologies. “Thanks to the hard work of our talented team, we have successfully realized red-emitting microLEDs based on our unique pyramidal structure.”
The power of Pyramidal MicroLEDs
Polar Light Technologies’ revolutionary pyramidal microLEDs are engineered using a novel bottom-up approach, offering several key advantages compared to traditional designs:
- Reduced Strain: The pyramidal structure mitigates strain in lattice-mismatched InGaN/GaN materials, enabling the use of a single material system for all three primary colors (red, green, and blue).
- Enhanced Integration: The design simplifies device construction by facilitating the integration of the frontplane with a backplane.
- Etch-Free fabrication: Eliminating the need for etching preserves performance, especially at smaller dimensions, and enables the creation of even smaller “nanoLEDs.”
- Improved Manufacturing: The technology allows for easier integration with CMOS and TFT technologies, streamlining the manufacturing process.
Unmatched Performance and Bright Future
This breakthrough by Polar Light Technologies has the potential to revolutionize the display industry. Pyramidal microLEDs promise brighter, more energy-efficient displays with wider viewing angles and improved color accuracy.
