Aledia takes another major step forward in micro-LED technology

/in , /by

Aledia has announced the commercial launch of FlexiNova, the first patented high-voltage micro-LED platform. According to the company’s announcement, this platform enables the implementation of high-performance displays using smaller chips. Supported by CEA-Leti and France’s 2030 program, FlexiNova signifies the transition from the technical feasibility stage of micro-LEDs to the industrial production stage.

The industry’s first 3D nanowire-based micro-LED operating at 6V has been manufactured on a 200mm silicon wafer, demonstrating the maturity of silicon micro-LED mass production technology. Felix Marschall, Chief Sales and Marketing Officer at Aledia, stated, “FlexiNova transforms micro-LEDs from a technological promise into a scalable industrial reality.” The company emphasized that its FlexiNova platform can resolve industrial bottlenecks by supporting all voltages and chip sizes while maintaining stable, high luminous efficiency. The 6V operating principle of this device, as illustrated in the figure, consists of a structure connecting two nanowire blocks in series. The initial demo device was showcased at CES 2026, and the company announced that initial sample deliveries to major industrial players in the field have already been completed.

According to UBI Research, Aledia is a French company possessing 3D WireLEDTM technology, with its core focus being Gan-on-Silicon 3D Nanowire LED technology on 200-300 mm wafers. In collaboration with Belgium’s QustomDot, it has combined nanowire LED and quantum dot color conversion technology to develop a full-color Micro-LED display. Aledia’s technology could serve as an alternative solution to address the steep efficiency decline issue faced by existing AlInGaP (red) based devices in ultra-small (2-3µm) pixels for future AR/VR applications. At the Touch Taiwan 2024 exhibition, Aledia showcased a display device using QD color conversion on a 1.5µm blue Micro-LED. For the 1.5µm blue chip device, Aledia announced an external quantum efficiency (EQE) exceeding 32%. At CES, Aledia presented its single-chip integrated RGB micro-display technology developed for augmented reality glasses.

Aledia is a micro-LED R&D startup headquartered in Grenoble, France, which was spun out from the French National Scientific Institute CEA-Leti in 2011. LEDs and plans to supply them for all display applications that require them. The company claims that the properties of nanowires make them energy efficient and suitable for high resolution, but if the pixels are configured in the form of m x n arrays, they will also be the best choice for large-area, high-brightness product lines.

Aledia’s core technology is a method of growing GaN nanowires in a three-dimensional structure on a silicon substrate. This technology is suitable for high-performance display solutions such as augmented reality (AR) because the direction of light emission can be precisely controlled.

Aledia holds approximately 300 patents and has completed the development of the world’s highest efficiency of 32% EQE in micro-LEDs with a size of 1.5 µm or smaller, its manufacturing technology, and circuit bonding technology.

Aledia is investing US$200 million in Champagnier, France, to build a microLED production line that is expected to be completed in the first half of 2025. The facility will be capable of mass producing microLEDs on 8″ and 12″ silicon wafers with a capacity of 20K wafers per month; Aledia is expected to produce micro-LEDs for AR in earnest.
