µLED displays can challenge LCD and OLED with better performance, efficiency and lifetime but adoption is limited by high costs. Using simple equipment fluidic assembly can build 4K displays in minutes. eLux produces high yield and uniformity by removing weak LEDs before assembly. Defects mapped by micro-photoluminescence are captured so only known good die are harvested for assembly. Fluidic assembly is gentle so excess µLEDs are recycled and the combination of selective harvest with recycling enables near 100% utilization of µLEDs. Low-cost high yield assembly using known good die is a route to economic mass production of µLED displays.
I am CTO of eLux, Inc. founded in 2016 to commercialize the microLED display technology developed at Sharp Labs of America. I lead the technical innovation in a collaboration with LED manufacturers, materials suppliers and display backplane manufacturers to make large area direct emitting displays using massively parallel fluidic assembly techniques. I have done process integration in 13 different semiconductor fabs including the lead lots in four new fabs. I have published on the properties of ferroelectric materials, semiconductor memory and silicon nanowires. I hold 102 US patents primarily in the fields of display, materials processing, and thin-film transistors.
