We’re pleased to feature Ingantec, fabless semiconductor and microLED solution provider, in our latest MicroLED Industry Association spotlight series.
We spoke with Alan Yeung, Ingantec's CEO and co-founder, to learn more about the company's technology, business, achievements and goals.
Can you introduce your company and technology?
Ingantec is a fabless semiconductor and microLED solution provider. Our mission is to remove the constraints blocking the commercialization of full-color, monolithic microLEDs. We achieve this through breakthroughs in native InGaN red emission—leveraging strain engineering, defect shielding and spectral stabilization. Our core platform enables two major advancements:
- Spectrally stable InGaN-based red microLEDs that maintain high efficiency under elevated operating temperatures and high current densities;
- Monolithic RGB integration, placing native red, green and blue subpixels on a single GaN wafer rather than stitching together disparate material systems like phosphide and nitride.
Our founding team pairs scientific depth from world-class research labs at UC Santa Barbara and UW-Madison with executive leadership from Apple and Foxconn. Beyond our proprietary R&D, we have secured IP licenses from UCSB, UW-Madison, and Yale University.
Our product portfolio spans from red chip-on-wafers to monolithic RGB wafers utilizing both stacked and planar integration architectures.
What are your next goals regarding microLED technology and business?
On the technology front, our roadmap goes from standalone red wafers to full RGB wafers, executing on dual monolithic architectures: a stacked/vertical approach and a planar/lateral approach. These platforms serve next-generation applications requiring high temperature and current density tolerances.
On the commercial side, our goal is to become the premier supplier of red and native RGB microLED wafers for AR/spatial computing displays, medical diagnostic light sources, and AI optical interconnects. As a fabless provider, we are actively scaling our supply chain network, strategic partnerships, and intellectual property portfolio to support full commercial integration with our customers.
Can you say why you joined the MicroLED Association and what you hope to achieve?
Commercializing native RGB microLEDs is an ecosystem-wide challenge that no one company can meet alone. It takes partnerships and alignment across materials, epitaxy, device design, backplane integration, and system engineering. Joining the MicroLED Industry Association provides us valuable visibility into where the ecosystem is heading, and a channel for us to collaborate with key leaders.
As the microLED industry matures toward standardization and mass production, we aim to serve as a key enabler—helping translate isolated technical demonstrations into scalable commercially viable successes.
What is your biggest challenge, and success to date in the microLED industry?
The biggest challenge is what is often called the green gap problem, extended into red: native nitride LEDs are excellent in efficiency at short wavelengths, such as blue. However, as you push InGaN toward green and red, higher indium incorporation increases lattice strain, causing efficiency drops and blue shifts.
Our biggest success has been proving out our InGaN platform against these material limits.
We’ve demonstrated record peak external quantum efficiency (EQE) and maintained spectral stability at current densities that reflect real AR and high-power operating environment.
We have secured this technological lead with global freedom to operate, supported by a robust IP portfolio spanning proprietary patents and top-tier university licenses.
Can you detail your latest prototype or demonstration?
Our current commercial product demonstration is a chip-on-wafer built on our Spectrally Stable Red (SSR) red InGaN platform. SSR is engineered to maintain peak and dominant wavelengths under the drive currents and thermal loads typical of micro-display light engines—rather than washing out or shifting color the way many red microLEDs do.
For monolithic RGB wafers, we are pursuing two parallel integration architectures.
The first is a stacked approach that vertically integrates or bonds native red, green and blue wafers, using our high emission power to counter the light loss that stacking usually introduces. The second architecture is a planar configuration that places native red, green and blue subpixels side by side on a single wafer for maximized manufacturing yield and throughput.
Both pathways harness our three underlying technology platforms—spectral stabilization, nanoporous GaN strain engineering, and V-defect shielding—to bring InGaN red to a performance level compatible with blue and green on the same chip.
How do you see microLEDs changing the display industry in the next 5–10 years?
We think native, monolithic RGB InGaN will become the default architecture for microLED displays in AR and spatial computing. Beyond smart glasses, this same native RGB platform will scale into smartphones, wearables, and premium TVs, while enabling non-display applications like optical interconnects for AI infrastructure and medical diagnostic light sources.
By growing or placing all three primary colors on a single GaN wafer—eliminating the need to pick and place separate material systems—we can take out a lot of cost, yield risk, and packaging complexity. Once these material constraints are removed, microLED technology can finally compete on its core physical strengths: unmatched brightness, power efficiency and pixel density.
