An California-based integrator, Just One Touch/Video & Audio Center, announced that it has installed the first-ever residential installation of Samsung's latest 219-inch microLED The Wall TV. The price of this project was about $800,000. The installation took three days to complete.

The 219-inch display is made from the IW-008A modules, which offer a 0.84 mm pixel pitch, 120Hz refresh rate, a peak brightness of 2,000 nits and a maximum brightness of 250 nits.

Belgium-based microLED microdisplay developer MICLEDI has demonstrated 630nm wavelength red GaN with a full-width-half-max (FWHM) in the range of 50nm. New red microdisplay samples are projected to be available to customers before the end of the year.

MICLEDI says that its red GaN device is compatible with the company's proprietary CMOS-fab technology and it follows the identical process recipe of the company’s blue and green arrays for consistency. The new red device is tailored for 300 mm processes for high-volume mass production.

During the company's latest conference call, Samsung Electronics said that it aims to increase sales of its microLED TVs in 2023 and continue to expand its product range with more TV sizes, as it continues to provide a "differentiated customer experience".

Samsung recently started producing its smallest microLED TV, 89-inch in size, on LTPS backplanes. Its larger 101-inch and 114-inch LTPS models, however, are still not in production.

BOE announced that it has developed a new high-transparency mini-LED directview display, that offers a transparency of 65% and a brightness of over 1,000 nits.

BOE says that it achieved this high performance by optimizing the pixel circuit and designing a new pixel structure. BOE also used a new innovative design for the transparent area (it achieved a transparency of 95% in the transparent areas) and an optimized wiring structure.

Hong Kong based microLED microdisplay developer Raysolve Technology announced its first demonstration of a microLED microdisplay - a full-color 0.39" display.

The display is based on blue LEDs and a photolithographic QD color conversion layer. Raysolve is using a unique process, which is semiconductor process compatible, to create a novel optical design and material structure that achieves higher contrast, improved colors and a more efficient display.

The MicroLED Industry Association is happy to welcome LG Electronics as the latest member to join the newly formed association. LG Electronics joins 23 other companies to help advance the microLED industry and related technologies.

The MicroLED Industry Association was established to help accelerate the adoption of microLED display technologies. The new association brings together leading companies and organizations active in the MicroLED industry and provides an ideal forum for solving common technology issues, fostering cooperation and sharing relevant information, resources and tools. The association will also work to promote its member companies, their technologies and products.

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.

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.

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.

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.
