3D Nanowire microLED developer Aledia announced that it has successfully demonstrated a fully functional monolithic RGB epitaxial wafer. This breakthrough validates the company’s end-to-end monolithic RGB process, enabling the emission of red, green, and blue light from a single epi wafer processed in one run.
Aledia’s proprietary nanowire-based approach enables the simultaneous growth of nanowires with diameters
ranging from 100 nm to 400 nm, depending on the color, all within a single process step.
The company also demonstrated a sub-pixel pitch of 2.5 μm, corresponding to a 5.0 μm × 5.0 μm pixel size. Aledia is now advancing toward an ambitious roadmap targeting a 2.0 μm sub-pixel pitch for both monochrome and monolithic RGB displays.
Aledia recently validated its 9V microLEDs on a 200 mm silicon wafer and demonstrated 15x30 um blue microLEDs on the 9V 200 mm platform. The company also announced the commercial availability of its 3D-Nano microLED platform produced on 200 mm silicon wafers.
In October 2025 we posted a spotlight article on Aledia, a MicroLED Industry Association member.
Meet Aledia at MicroLED Connect 2026
