Over the last twelve years, Aledia has developed two unique 3D microLED technologies using nanowire growth on 200 and 300 mm silicon substrates. In this presentation, we will first describe how the efficiency of the devices is not negatively impacted at smaller device sizes, making Aledia’s microLEDs an ideal solution for a wide range of displays, including wearables, automotive, and large displays. We will as well introduce another technology where directive light emission from the nanowires dramatically enhances efficiency for AR applications.
Pierre Tchoulfian has been involved in microLEDs development for more than 13 years with numerous publications and 10+ patents. He is currently responsible for the product and technology development group at Aledia. His academic background includes a joint engineering degree from Phelma, Polito di Torino and EPFL. He obtained a PhD in nanoelectronics from Grenoble University, France.
