The MicroLED-Info newsletter (October 25, 2022)

In May 2021 Quantum Dots developer Nanosys acquired 3D Nanowire microLED display developer Glo. The company today announced that it is selling its GaN MicroLED fab and its related engineering team to Avicena, a startup that develops microLED-based optical interconnects. Nanosys received an equity stake in Avicena.

Avicena will use the fab and team to develop and produce high-speed GaN microLEDs optimized for parallel multi-Tbps interconnects. Before the agreement, Avicena was using the Nanosys fab for the development of its microLEDs.

TechBlick will soon host its virtual microLED and QD event, and here is a good preview of some of the technologies and advances that will be detailed during the event. MicroLED-Info readers enjoy a special discount to this interesting upcoming industry event.

We highlight important advancements in MicroLED and/or QD displays in this article using technology slides. These advancements of the art will be presented at TechBlick’s 2-day global conference on “Mini- & Micro-LED Displays: Markets, Manufacturing Innovations, Applications, Promising Start-ups” taking place online in TechBlick’s ‘in-person virtual’ platform on 30 Nov - 1 Dec 2022.

The agenda includes the likes of Samsung, Sharp, AUO, Coherent, ASMPT, Komori, CEA, Micledi, 3D Micromac, Allows Semiconductors, and many more. Full agenda can be seen here.

This conference is supported by the MicroLED Association.

We're happy to interview eLux, as part of our new series of interviews with MicroLED Industry Association members. eLux was established in 2016 in the USA as a spin-out from Sharp Labs of America. eLux expertise and intellectual property development focus on the massively parallel assembly processes that enable low cost manufacturing of microLED displays.

Q: Hello! Can you introduce your company and technology?

eLux, Inc. was founded in 2016 as a spin-out from Sharp Laboratories of America. eLux's objective is to develop direct emission displays based on microLED technology targeting large format displays for video wall and television applications. Core personnel of eLux, including Jong-Jan Lee (President and CEO) and Paul Schuele (CTO), had extensive experience in display development working at Sharp Labs.

The work done at company headquarters in Vancouver, Washington consists of development of fundamental microLED assembly technology and characterization of display performance and reliability. Direct emission display development involves extensive collaboration with microLED suppliers and manufacturers of display backplanes, so significant effort is involved in prototype fabrication, which takes place in Taiwan.

QustomDot announced an agreement with France-based 3D GaN LED developer Aledia to co-develop a full-color microLED displays, based on Aledia's high-efficiency Gan-on-Silicon 3D Nanowire LEDs grown on 300 mm wafers coupled with QustomDot's high performance quantum dots color conversion technology.

QustomDot developed a patented method to produce high-quality and stable QD materials suitable for microLEDs, that are heavy metal free. A few months ago the company announced it is co-developing microLED displays with MICLEDI.
