We're happy to interview InZiv, as part of our series of interviews with MicroLED Industry Association members. InZiv develops testing and inspection equipment for display makers focusing mostly on MicroLED displays (but also QLED and OLED).

Q: Can you introduce your company and technology?

InZiv is a leader in display testing and inspection, providing high-resolution testing and inspection equipment to today’s foremost advanced display developers and manufacturers. InZiv’s proprietary nano-optical technology specializes in microLED displays, but also extends to QLED and OLED. With the size of pixels now reaching the single-micron scale, our testing equipment provides comprehensive data and nanometric resolution, empowering display manufacturers to improve their manufacturing processes, lower production costs, and enable greater access to the use of these displays by all consumers. Based in Israel, the company was founded in 2018, and counts a number of the world’s leading display manufacturers among its customers.

China-based MicroLED microdisplay developer Jade Bird Display announced that it has developed a higher-efficiency AlGaInP-based (native) red microLED, that achieves a brightness of 750,000 nits, an increase of 50% compared to its currently-used emitter. The company says that this it the industry's brightest native red emitter.

JBD says that it managed to redistribute the local charge carriers by a breakthrough in surface treatment process and in this way, minimize the surface non-radiative recombination and boost the efficiency. The company says it expects to implement this technology in mass production by middle of 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.

AU Optronics revealed that the company plans to start mass producing microLED displays for wearable applications by the end of 2023. The company developed its own mass transfer technology that it says makes it possible to produce displays commercially. The company also plans to use microLED display technology to produce automotive displays, and TVs, later on.

AUO demonstrated a wearable microLED display back in 2021 - a a 1.39-inch 472x472 (338 PPI) full-circle panel, that was developed together with PlayNitride.

The MicroLED Association is hosting an open webinar in which we will give a talk focused on microLED yields: explaining the problem and its implications, and discussing the various strategies and next-generation technologies by microLED association members that aim to overcome and mitigate the problem.

The webinar will take place on February 21st (Tuesday) at 16:00 CET. You can use the following link to register, at no cost.

Market analysts from Omdia say that the XR market (which they define as a combination of AR, VR and MR) will grow from 24 million units in 2023 to almost 90 million units in 2028, a CAGR of 67%. In terms of revenues, the market (XR displays) will reach $1.15 billion in 2023.

Looking at 2022, Omdia's Senior display analyst, Kimi Lin, says that for the AR market the leading technology is OLED microdisplays, with a market share of 70% and shipments of 670,000 units. Omdia says that 30,900 MicroLED displays were shipped (these are all JBD's 0.13" VGA ones, as this is the only commercial microLED). In addition - Laser-beam systems (188,700 shipments), LCoS (69,300) and DLP (3,200).

Aixtron announced today that ams OSRAM has qualified Aixtron's AIX G5+ C and G10-AsP MOCVD systems on 200mm wafers for a Micro LED production.

ams Osram will be using Aixtron's systmes at its upcoming 200 mm mass production line in Malaysia, which is expected to begin production in 2024.

The MicroLED Industry Association published today a new white paper, that is focused on MicroLED production yields. This whitepaper discusses microLED yields, the current status, challenges ahead and several strategies and technologies that should help to mitigate the yield problem. Together with the white paper, the association is also hosting an open webinar.

Yield is an important parameter for display makers, as low yields can drastically increase production costs per panel sold. In the microLED industry, yields are even more crucial and are still a major challenge. In addition, as microLED production involves several separate steps, the yield discussion is more complex compared to the situation in LCD or OLED production.

The white paper is published on the MicroLED Association's website, and is open to the public.

Last month AR developer Mojo Vision announced that as it finds it challenging to raise more funds, it is changing its focus to develop its microLED display technology, and canceling its smart contact lens system R&D project.

A couple of years ago, Mojo Vision announced that it has developed a 14,000 PPI monochrome (green) microLED microdisplay, that is the world's highest density microdisplay. The company now updated its website, which says that its technology can reach up to 28,000 PPI.

Researchers from the US and Korea, led by MIT, developed full-color vertically-stacked microLEDs that achieve the highest array density (5100 PPI) and the smallest size (4 µm) reported to date.

To end up with such high resolution and small microLED chip size, the researchers used a 2D materials based layer transfer (2DLT) technique. The resulting microLEDs, that have near-submicron thickness, are grown on 2D material-coated substrates, removed, and then stacked.
