Polar Light Technologies takes technology leap in microLEDs for smart glasses and AR displays
Linköping-based Polar Light Technologies is raising millions in capital from five groups of business angels to realise a technology leap in the microLED field. The breakthrough is based on years of research at Linköping University and aims for a billion-dollar market.
The innovation behind Polar Light Technologies makes it possible to create new and much smaller light sources with LED technology, so-called microLEDs. This is a technology that makes it possible to create super-small, yet bright displays. - Our semiconductor technology is based on a proprietary manufacturing method that is based on many years of research and provides a light source with higher efficiency and thus better energy efficiency, says Per-Olof Holtz, founder of Polar Light Technologies and Professor Emeritus at Linköping University.
Building structures one atom at a time
In today's LED technology, the structure is etched, resulting in an uneven surface with many defects and thus lower efficiency. Polar Light Technologies has instead developed a technique to build microLEDs in the form of small pyramids using controlled crystal growth, atom layer by atom layer.
The technology behind the semiconductor-based nanostructure opens up the possibility of generating light in any colour in a controlled light flux down to single photons or light particles.
- Our approach to building pyramid shapes has made it possible to exploit quantum effects that increase light intensity and reduce energy consumption,' says Per-Olof Holtz.
New display technology for smart AR glasses
In the first instance, the technology will be developed for projecting information, for example on the windscreen of a car (head-up display, HUD) and for portable displays such as
Head-mounted display (HMD) smart glasses. Two areas that are growing rapidly in combination with various forms of augmented reality or AR.
- The total world market for microLEDs is estimated to reach USD 300 billion by 2028.Polar Light Technologies aims to become a supplier to other companies developing new products with the technology, says Peter Nilsson, CEO of Polar Light Technologies.
Five groups of business angels
Investors in the company include Linköping Business Angels and Norcorpius together with GAEU Ventures, Sustainable Energy Angels II and Stoaf III SciTech.
- Polar Light Technologies has a unique cutting-edge technology, developed within Linköping University, that can ultimately help reduce our energy consumption. The company is run by a fantastic passionate team with deep expertise, says Mattias Weinhandl, co-founder of Linköping Business Angels (LIAF).
The company has globally covering patents on the new nanostructure.

Många fördelarna med pyramidala kvantbrunnar
Polar Light Technologies LEDar baserade på pyramidala kvant-brunnar/-prickar visar upp unika egenskaper som extremt små dimensioner (ner till sub-um), hög verkningsgrad (resulterande i mindre batteribehov med bättre laddningskapacitet), höggradigt polariserat ljus, hög frekvens (upp till 10 GHz - 100 ps livstid) och kontrollerbart ljusflöde ner till enskilda fotoner. Samtliga parametrar överträffar de LED-strukturer som finns tillgängliga idag med god marginal. Innovationen gör det möjligt att generera linjärpolariserat ljus med en hög polarisationsgrad.
