Porotech leading ‘One-Stop AR Solution Alliance’ to accelerate AR commercialization
At SID Display Week 2025 (13–15 May), fabless micro-LED company Porotech (a spin off from the Cambridge Centre for Gallium Nitride at the UK’s University of Cambridge that has developed porous GaN material and has an R&D center in Hsinchu, Taiwan) is leading the ‘One-Stop AR Solution Alliance’ alongside key partners Foxconn, Rayprus, GIS, and Jorjin with a grand showcase in booth 1208 at the San Jose McEnery Convention Center.
The joint exhibition presents a comprehensive, one-stop augmented-reality (AR) solution spanning materials, optical engines, optical modules, AR glasses full system assembly, and mass production — propelling AR technologies from innovation to commercial reality.
Building a complete AR supply chain
As the alliance's core technology leader, Porotech has pioneered the industry’s first 8-inch platform designed specifically for micro-LED applications. It has achieved a breakthrough pixel pitch of just 1.25μm, demonstrating the potential of GaN-on-silicon micro-LED technology.
As part of its drive toward commercialization, Porotech has launched its latest red LED innovation. Not only offering five times the brightness of any other conventional red emitters, SpectraCore also features an ultra-narrow emission spectrum and exceptional color purity, it is claimed. Also, the wavelength remains stable under all driving conditions, showcasing superior thermal stability and long-term reliability.
Porotech has hence overcome one of the biggest barriers to full-color micro-LED displays: the performance and stability of red emitters. By leveraging its proprietary 8-inch wafer platform to ensure scalable mass production, Porotech says it is laying the groundwork for full-color near-eye displays and marking a critical step forward in the commercialization of micro-LED technology.
InGaN Red addresses longstanding challenges in micro-display technologies. Traditional AlInGaP-based red LEDs have faced issues with low efficiency and poor reliability, hindering their adoption in consumer electronics.
Claiming to be the first company to commercialize InGaN-based red LEDs in 2021, Porotech says that its InGaN red LEDs deliver superior efficiency and reliability, with optoelectronic properties closely aligned with InGaN blue and green materials — enabling seamless platform integration.
However, technical challenges like wavelength drift, broad emission linewidth, and limited color purity have persisted.
With SpectraCore, Porotech has launched an InGaN red LED that is said to excel in brightness, efficiency, and color purity, advancing the realization of full-color micro-LEDs.
At Display Week, Porotech is demonstrating its comprehensive vertical integration capabilities across the micro-LED ecosystem — from material innovation, wafer processing, chip-on-carrier (COC), chip-on-wafer (COW), LED chip fabrication, and final panel applications — solidifying its role as a catalyst for micro-LED commercialization.
Together with its alliance partners, Porotech says it is unveiling a blueprint for next-generation AR display technologies.
