Driver IC developer Solomon Systech launched what it says is the world's first PM-MicroLED display driver, the SSD2363. Solomon Systech targets applications such as wearables, home appliances and industrial applications.

The SSD2363 supports a range of resolutions up to 256x256, full-color, with 768 segments and 256 common output, SPI and MIPI interface and sizes up to 3-inches. The company is now sampling the new driver.

We're happy to interview Coherent, as part of our series of interviews with MicroLED Industry Association members. Coherent is one of the world's leading laser innovators and manufacturers, providing systems and components for the production of OLED and microLED displays.

Q: Can you introduce your company and technology?

Oliver Haupt, Director, Marketing, Display Vertical, Coherent Corp: For over 50 years, we have been providing high-performing, reliable photonics-based solutions that have become the enabling tool in many applications. Today, Coherent Corp. is one of the world’s leading photonics innovators and manufacturers.

Displays are getting larger and more interactive in our homes and cars. State-of-the-art displays are slim, bendable, and high-resolution, with a wide color gamut. Future displays will range in size from tiny ones for AR/VR applications, to more than 100-inch in diagonal for very large wall TVs.

MicroLED developer VueReal announced that it was awarded CAD$10.5 million (USD$7.7 million) in government support to scale up its micropixel fabrication and printing solutions. Vuereal will receive the funds from Sustainable Development Technology Canada (SDTC) and InvestOntario.

VueReal says that this funding will be part of a CAD$40 million production line facility project, that will employ 75 full permanent jobs in Waterloo, Canada.

Researchers from Korea's KIMM institute have fabricated full-color flexible microLED devices, using blue LEDs and perovskite quantum dot color conversion layers. The demonstrated device featured  1 mm pixel pitch LEDs (25.4 PPI) and could be bent with a radius of 5 mm without being damaged.

The researcher used a perovskite-QD and siloxane composite using ligand exchanged PQD with silane composite followed by surface activation by an addition of halide-anion containing salt. Due to this surface activation, the researchers say that it was possible to construct the PQD surface with a silane ligand using a non-polar organic solvent that does not damage the PQD. As a result, the ligand-exchanged PQD with a silane compound exhibited high dispersibility in the siloxane matrix and excellent atmospheric stability.

Researchers from Korea's KAIST have found that by changing the epitaxial structure of microLEDs, it is possible to fundamentally resolve the problem of efficiency degradation in microLED devices. In other words, it is possible to create microLEDs in which the efficiency does not drop with size. 

The researchers discovered that the specific epitaxial structure of the microLED changes how the current drives to the sidewall of the microLEDs. Based on that, the researchers developed a epitaxial structure that is not sensitive to sidewall defects. The proposed structure also reduces generated heat by about 40% compared to standard microLEDs.

SID's DisplayWeek is the world's leading display conference, and the MicroLED-Info team will attend this year's event, after several years that we did not attend due to the pandemic. DisplayWeek will take place in Los Angeles in May 21-26, and will bring together a large part of the display industry. We're looking forward to seeing new display technologies, products and demonstrators and meeting up with industry leaders!

DisplayWeek includes a 3-day exhibition, 4-day technical symposium, short courses, seminars, three focus conferences (business, investors and market-focus) - and more. We'll be happy to schedule meetings - so if you plan to come to the event, do contact us. We're really looking forward to a week full of display technologies!

The European Electronics Display Conference (edC), which takes place next week at Nuremberg, Germany, is a leading display conference, which takes part as part of the embedded world event. The conference focuses on industrial and automotive displays, and includes two days of keynote speeches and sessions.

MicroLEDs are featured at the conference, as the organizers realize the importance of the next-generation display technology. We had a short talk with the conference charimen Prof. Dr. Karlheinz Blankenbach from Pforzheim University's Display Lab. 

Q: Thanks for taking the time to talk with us, Dr. Karlheinz. Can you tell us a bit about the Electronic Display Europe Conference?

NS Nanotech announced that it is building a new R&D center in Montréal, Canada. In this center, the company will develop technologies based on exclusive microLED display technology patents licensed from McGill University.

US-based NS Nanotech is developed nanowire microLED technologies. NS Nanotech Canada (the new R&D center) signed an initial agreement with McGill University to start collaboration with top research scientists there including Prof. Songrui Zhao, that holds numerous patents and is advancing the state of the art in molecular beam epitaxy (MBE) and other foundational technologies
