Aledia has developed a technology allowing to grow on 200 mm or 300 mm Si wafers GaN nanowires (NWs). Those NWs can be used for manufacturing LED structures and Aledia has developed a technology allowing to grow in the same growth run the Red, Green and Blue active regions of a RGB array with a subpixel pitch that can be reduced down to 1.25 µm. This allows to drastically reduce the size of a micro-LED micro display and the RGB light engine for augmented reality.
