Aledia

3D Nanowire MicroLED developer Aledia announced the commercial availability of FlexiNova, its patented high-voltage microLED platform designed to unlock scalable, energy-efficient Direct-View microLED displays for global markets.

The company says it is the first in the world to successfully manufacture 3D Nanowire based microLEDs operating at 6V, with an ultra-compact 15 µm × 30 µm single body chip size, manufactured on 200 mm silicon wafers. The company, together with its partner CEA-Leti, is continuing to develop the technology and is developing a full portfolio of 6V and 9V operation with a constant efficiency for chip sizes down to 3.5 µm.

3D Nanowire microLED developer Aledia announced that it has validated its 9V microLEDs on a 200 mm silicon wafer. Specifically, it demonstrated 15x30 um blue microLEDs on the 9V 200 mm platform.

The company says that utilizing the higher 9V voltage, compared to their previous platform voltage, directly enables lower current and improved system efficiency for ultra small microLEDs. Aledia says that its blue 3D Nanowire LEDs offer high efficiency on any chip size.

We're happy to interview Pierre Tchoulfian, CTO of Aledia, as part of our series of interviews with MicroLED Industry Association members. France based Aledia, leading the next-generation displays with its 3D silicon nanowire–based microLED technology, designed to dramatically lower production costs. Backed by over €360 million in funding, Aledia is expanding production with its FlexiNOVA epiwafer platform and a planned €140 million fab. With more than 250 patent families, the company is advancing both large-display and next-generation AR microLED platforms.

Pierre is a recognized MicroLED innovator with 14+ years advancing technology and product development, shaping next-generation display solutions with over 10 patents and numerous publications.

Can you introduce your company and technology?

Aledia is a deep-tech company at the forefront of display innovation, focused on redefining what’s possible with microLED technology. We were founded in 2011 out of CEA-Leti research labs and are headquartered in Grenoble, in the heart of Europe’s “Display Valley.”

For more than a decade, microLED technology has captured the imagination of display engineers, semiconductor innovators, and industry analysts. The promise has always been clear: unmatched brightness, durability, and energy efficiency. The challenge has been turning that promise into a mass-market reality, a process that has proven to be complex and slow.

Now, in 2025, the pieces are finally coming together. From materials breakthroughs to smarter manufacturing methods, microLED is at a critical inflection point. At Aledia, we have always believed that solving physics was only part of the equation. True success also depends on solving economics, process scalability, and systems integration.

This year, momentum is building across all these areas.

At the Core: Materials and Emission Mechanics

At Aledia, we are pioneering a fundamentally different approach to microLEDs. Unlike traditional planar technologies, our 3D microLED architecture, built from silicon nanowires, enables far greater light extraction, power efficiency, and manufacturability using existing 200 mm IC manufacturing lines.

Aledia announced that it has successfully concluded the 3-years CLEDIA project, to integrate an artificial intelligence (AI) system dedicated to the optimization of epitaxy processes.

The The CLEDIA project, co-financed by the Auvergne-Rhône-Alpes Region and Bpifrance was a collaborative innovation between Pollen, Aledia and the laboratories at the University of Clermont Auvergne (LIMOS  and LMBP). 

3D Nanowire MicroLED developer Aledia launched its new FlexiNOVA product-ready epiwafer platform, saying that first samples will be available for customers in the second half of 2025, in both 6V and 9V variants.

FlexiNOVA microLED wafers will be offered to display makers to be integrated into full displays, targeting applications such as wearables, automotive displays, TVs and monitors. The FlexiNOVA platform offers high flexibility in chip size, shape, and power usage. 

France-based microLED developer and MicroLED Association member Aledia announced that it has finished the construction of its $200 million microLED production line in Grenoble, and the company is now starting to produce AR microLED microdisplays based on its 3D Nanowire platform.

The new microLED microdisplays are full color displays, based on monolithically grown native red, green and blue devices. The company says that is 3D GaN Nanowire material platform is more efficient and bright than regular (2D) LEDs. The company grows the LED on 8-inch and 12-inch silicon wafers, and can currently ramp up to almost 20,000 monthly wafers.

In the past year, microLED startups have raised over $200 million. As some companies (most notably Aledia and JBD in this case) mature and start to build production capacity, the need for funds grows, and we have indeed seen large investment rounds in these companies.

• Kubos Semiconductors: $2 million (May 2024)
• MICLEDI: $17 million (March 2024)
• Mojo Vision: $21.1 million (October 2023)
• Aledia: $129 million (October 2023)
• Comptek Solutions: $8.6 million (August 2023)
• QNA Technology: $4 million (August 2023)
• JBD: A4 round, estimated at $30-130 million (June 2023)

It is great to see these recent funding successes, which will hopefully lead to increased innovation and also initial production. It should be noted that most (if not all) of these financing rounds have been finalized before Apple made its decision to cancel its main microLED wearable project. We do not see Apple's decision as having a major impact on the long-term viability of microLED technologies or on the industry - but we do know that some investors are now hesitant to invest in this market following Apple's project cancellation. 

France-based microLED developer Aledia announced some breakthrough advances. The first one is a new <1.5 um microLED device that has the world's highest EQE of 32%. Aledia says that this new device leads to a Wall Plug Efficiency (WPE) of 320 milliwatts of visible light output per watt of electrical power input. 

As you can guess from the first subject, Aledia has successfully reduced its microLED pixel size to 2 um, or even below. Finally, Aledia says that it has reached a 99% DCI-P3 color gamut. 

France-based microLED developer Aledia has closed a new financing round, raising €120 million from existing investors. The company also appointed Pierre Laboisse as its CEO (Giorgio Anania, the previous CEO, remains on the company’s board of directors).

Aledia's investors include CEA Investissement, Supernova Invest, and the SPI and Ecotechnologies funds. In 2020 Aledia announced that it plans to establish a 140 million euros LED production fab in Champagnier, near Grenoble in France. The company already raised 110 million Euros towards that goal, and now it has raised another significant amount of money. In total, the company raised over €360 million to date.
