The MicroLED-Info newsletter (March 28, 2023)

Today we published a new edition of our MicroLED and OLED Microdisplays Market Report, with all the latest information. The new edition, which includes our yearly report overhaul, offers more than 15 new updates, new companies, new brochures and attached files, more than 5 new devices and more.

Reading this report, you'll learn all about:

• The advantages of OLED and MicroLED microdisplays
• The microdisplays that are available on the market today
• Information on all companies involved in this market
• Future technologies and roadmaps

The report package also provides:

• A list of all OLED microdisplays on the market
• A list of all OLED and MicroLED microdisplays makers
• Microdisplays spreadsheet
• Over 25 datasheets, presentations
• Free updates for a year

This microdisplays market report provides a great introduction to MicroLED and OLED microdisplays, and covers everything you need to know about the current status of the market and industry. This is a great guide if you're considering to adopt OLED microdisplays in your product, if you're looking to learn more about next-generation micro-LEDs and if you want to understand this industry better.

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!

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.

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.

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.
