Glo

Glo AB operates at the intersection of nanotechnology and advanced electronics, focusing on the development and commercialization of next-generation LED products. The company was established in 2003, originating as a spin-out from Lund University in Sweden, building upon over a decade of foundational research in nanotechnology. This research was led by Professor Lars Samuelson, a prominent scientist in the nanometer structures field and a founder of Glo. His extensive background in solid-state physics and nanowire technology directly shaped the company's core technological direction.

The firm's business is centered on producing highly efficient microLEDs (mLEDs) using a proprietary gallium nitride (GaN) nanowire technology. This approach is designed to overcome the performance limitations of conventional planar LED manufacturing. Glo's technology enables the creation of red, green, and blue (RGB) emitters from a single material system, which allows for superior color stability and the potential to grow all three colors on the same wafer. A key benefit of this method is the ability to produce highly efficient white LEDs with excellent color rendering without needing phosphor conversion, a common practice in the industry. The company targets the advanced display, illumination, and automotive application markets. By developing these foundational components, Glo's business model appears to be based on supplying its advanced mLEDs and licensing its technology to manufacturers in these sectors.

In May 2021, Glo was acquired by Nanosys, a developer of quantum dot technology for displays, in a move to combine two leading-edge display technologies. This acquisition integrated Glo's microLED platform with Nanosys's quantum dot materials, aiming to create a highly competitive force in the display market, from wearable devices to large-scale TVs. Before the acquisition, Glo had successfully demonstrated several prototypes, including a 1.5-inch LTPS display and a high-resolution microdisplay, often in collaboration with industry partners like Japan Display and Kyocera. The company's operations are globally distributed, with foundational research in Lund, Sweden, and product development and pilot manufacturing in Sunnyvale, California.
