Milwaukee-based Ingantec has unveiled red InGaN micro-LEDs that reached a peak external quantum efficiency exceeding 20%. The results were presented by CEO Alan Yeung at TechBlick's MicroLED Connect.
Why it matters
Native red InGaN emitters could simplify display manufacturing by reducing reliance on complex, heterogeneous architectures. This development overcomes historical challenges related to strain and efficiency degradation in red light-emitting diodes.
The 5µm devices achieved peak efficiency at a current density of 4-5A/cm, while maintaining 5-8% efficiency at high current densities of 40-140A/cm. Optical measurements were confirmed using an integrating-sphere at the University of California Santa Barbara.
The players
Ingantec
A fabless semiconductor company based in Milwaukee that specializes in advanced light-emitting diode architectures.
Alan Yeung
The CEO of Ingantec who presented the new micro-LED results at the TechBlick event.
The details
The devices utilize proprietary Spectrally Stable Red technology on conventional c-plane epitaxial structures to emit light at a 625nm wavelength. This approach moves away from traditional quantum dots or nanowires, relying instead on strain-engineering methodologies.
