An EIC Accelerator Detour: Aledia's Nanowire MicroLED Screens

The pitch Aledia made to the European Innovation Council in 2020 was about more than a better LED. Every LCD and OLED screen sold in Europe is driven by a thin-film transistor (TFT) backplane made in Asia. Aledia's SmartPixel, a microLED with its own microcontroller, would make that layer unnecessary, and so, according to its CORDIS objective, "for the first time ever, the display industry can be relocated in Europe". The EIC Accelerator pilot selected the project, SPEED, at its January 2020 cut-off with blended finance, and the EU contributed €2,423,743 towards a €3,462,490 budget.

The project closed in January 2023. Aledia grew its gallium-nitride LEDs on 300 mm silicon wafers, as promised. The SmartPixel samples for video walls and large TVs never appeared in public. The first product the Grenoble company calls commercial, FlexiNova, launched in January 2026, is a high-voltage microLED chip whose selling point, according to MicroLED-Info, includes "simplified TFT backplane designs". The technology survived; the route to a TFT-free European display took a detour.

Where Aledia Stands Now

Aledia is operating and still raising money. The French register lists it as an active SAS with 200 to 249 employees in 2024, according to the government company directory and Societe.com. Neither shows any insolvency proceedings, and the official BODACC gazette records 76 notices for the company, none of them a court judgment. It records changes of share capital in March 2025, August 2025, March 2026 and August 2026; the amounts behind them have not been announced. BODACC published a change of registered office in October 2024, and the register now gives the Champagnier factory site as the head office.

Its 2026 news flow is steady. In January it launched FlexiNova; in April it reported a monolithic RGB epitaxial wafer, red, green and blue emitters grown on one wafer in one run, with a 2.5 µm sub-pixel pitch, according to TrendForce and Aledia's news page. In May it announced a partnership with the Taiwanese panel maker AUO to put its high-voltage microLEDs on AUO's display backplanes, a project selected under a France-Taiwan funding programme, according to LEDinside and Aledia. Its chief financial officer, Ness Benamran, said the partners intend to go "beyond displays" into optical interconnects and AR glasses.

The Technology: LEDs Grown as Nanowires on Silicon

Conventional microLEDs are cut from flat layers of gallium nitride grown on sapphire wafers. Aledia grows millions of sub-micron gallium-nitride wires standing up from a silicon wafer, which, the CORDIS summary says, improves the area efficiency of light generation. Silicon wafers come in larger sizes than sapphire and can be processed in semiconductor fabs; the research behind the approach began at the CEA in 2006, according to CEA-Leti, which still runs a joint laboratory with the company.

FlexiNova chips measure 15 by 30 µm and run at 6 V, with 9 V versions announced in April 2026, made on 200 mm wafers, according to Aledia and MicroLED-Info. Higher voltage per chip reduces the current a display has to drive. Aledia says first samples have gone to "major industry players"; it has not named them. For augmented reality, the company showed at CES 2025 microLEDs with red, green and blue grown on one substrate, which it said emit light in a naturally directed beam, according to Semiconductor Today and Compound Semiconductor.

The company's own figures for its patents vary. The CES 2025 releases and its website cite nearly 300 patents or patent families; its 2025 CSR report counts 248 active patent families.

What SPEED Promised, and What CORDIS Shows

The Commission's list of the January 2020 EIC Accelerator pilot winners names Aledia, Grenoble, as the only company on SPEED, with blended finance. The grant was signed on 2 July 2020 and the project ran from 1 August 2020 to 31 January 2023. Its goal, in the words of the CORDIS report, was "to finalize the development of the SmartpixelTM and to provide samples for different display markets such as video walls and large TV".

The report published for the second and final period, which covers August 2021 to January 2023, describes only first-year work: LED growth on 300 mm silicon wafers was demonstrated, and the risk-reduction work for a final demonstrator (CMOS design, back-end processes, backplane definition) was "partially" completed. The deliverables it lists as expected by the end, a 300 mm MOCVD growth capability and samples of a single pixel for laptops and an RGB SmartPixel for video walls and large TVs, are not reported as done, and CORDIS lists no results.

Aledia's next EU project shows how far the SmartPixel idea still was from a product. In BAMBAM, a Horizon Europe project it coordinated from September 2022 to August 2025 with a net EU contribution of €1,266,534.16 for Aledia, a consortium tried to print active microLED pixels, each with its own driver chip, onto low-cost boards for TFT-free video walls. Its final report says the consortium lit a 4 by 4 pixel matrix and a 325 µm RGB pixel but "could not deliver a fully populated display demonstrator before the end of the project", and that Aledia's R&D microLED was "not compatible" with the demonstrator's specifications.

1. GaN LED growth on 300 mm siliconDeliveredDemonstrated, per the CORDIS report; Aledia's line processes 8- and 12-inch wafers, per Semiconductor Today.
2. 300 mm MOCVD capability for productionPartialThe pilot line handles 12-inch wafers, but FlexiNova is made on 200 mm wafers.
3. Single-pixel samples for laptopsNot achievedNo samples announced by the company or a customer.
4. RGB SmartPixel samples for video walls and large TVsNot achievedNone announced; the follow-on BAMBAM project ended in 2025 without a full demonstrator.
5. Displays without a TFT layerNot achievedThe first commercial product is designed for TFT backplanes.
6. Individually driven µLEDs under 10 µm pitch by 2024Not achievedA 2.5 µm sub-pixel pitch was reported on an epitaxial wafer in 2026, not as driven pixels.

Delivery on SPEED was therefore partial: the materials milestone came in, the product milestones did not. That is not unusual for a grant meant to fund development, and the 300 mm growth result is a genuine step. But the samples were the point of the project, and neither the company nor any customer has announced them since.

The Money

In October 2020 Aledia closed €80 million as the first tranche of a planned €120 million Series D, led with €60 million by Bpifrance's SPI fund and joined by Intel Capital, Braemar, Demeter, Ingka, Sofinnova, Supernova, Tokyo Electron and Valeo, according to Frenchweb and Electro Optics. The EIC said in February 2022 that the EIC Fund had put €15 million into that Series D, the equity half of the blended award; Aledia is listed in the EIC Fund portfolio and on the official list of invested companies. Whether the remaining Series D tranches closed in full could not be verified.

In September 2023 its existing shareholders, including CEA Investissement, Supernova, Braemar and Bpifrance's funds, put in another €120 million alongside the state's French Tech Souveraineté programme, and Pierre Laboisse, a former executive vice-president of ams Osram, replaced the founder Giorgio Anania as chief executive, according to the Bpifrance press release, LEDinside and CEA-Leti. At CES 2025 the company put its total investment to date at $600 million and its Champagnier pilot line at over $200 million.

The accounts show what that money pays for. Aledia's net loss was €21.3 million in 2019, €65.9 million in 2022, €60.5 million in 2023 and €85.1 million in 2024, against revenue of €527,300 in 2024, according to the INPI annual accounts ratios dataset; Societe.com shows the same 2023 and 2024 figures. The 2020 and 2021 accounts were filed with a simplified, abridged publication, BODACC notes, and are not in the public dataset. Losses in the four years with public figures since 2019 add up to €232.8 million.

Why Europe Should Care

SPEED was sold on strategic autonomy, and the case is real. The BAMBAM report states that all electronic displays sold in the EU use panels made in Asia. The European Chips Act, in force since 21 September 2023, aims to build European capacity to design and manufacture chips and to make supply chains more resilient, and the EIC itself framed its investment in Aledia as part of that sovereignty agenda. A French fab growing LEDs on standard silicon wafers fits that agenda closely.

The detour matters for the same reason. A chip made for TFT backplanes, sold through a partnership with a Taiwanese panel maker, adds a European component to an Asian display supply chain; it does not replace that chain, which was the ambition the EIC funded. Aledia may still return to driver-integrated pixels, and its AR and optical interconnect work could matter more than displays. For now the revenue is small: €527,300 in 2024, the last year with filed figures.
