eLux

eLux, Inc. is a US-based company founded in 2016 as a spin-off from Sharp Labs of America, focused on developing microLED display technology. The company's core expertise lies in massively parallel assembly processes for manufacturing microLED displays cost-effectively. eLux has developed a proprietary fluidic self-assembly (FSA) technology for mass transfer of microLEDs, which can position millions of microLED devices per hour onto display backplanes. This process uses microLEDs dispersed in liquid that fall into place in wells built onto the substrate, enabling a sort of self-assembly without the need for pick-and-place techniques.

The company's technology can handle microLEDs sized from five to 200 micrometers, allowing for displays with resolutions ranging from 400 to 10 pixels per inch. eLux's approach offers flexibility in adjusting the microLED emitter area to size ratio and can work with both GaN-based blue/green LEDs and AlGaInP-based red LEDs. As of April 2021, eLux reported achieving a 99.987% natural yield in assembling over 518,000 GaN microLEDs in 10 minutes using their automated fluidic assembly tool. The company's displays use blue microLEDs with quantum dot color conversion for full-color realization.
