With SID2025, Aledia promises innovation in MICRO-LED displays.

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.

Aledia researchers let us know that they are ready to work together to solve the challenges of the micro-LED industry at SID 2025.
