MicroLED-Info is the world's leading microLED display industry portal since 2017. We provide a multitude of services to the microLED industry based on our extensive knowledge hub and industry connections.
MicroLED displays use ultrafine LED devices to create beautiful, flexible and highly bright and efficient displays.
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.
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.
ClassOne Technology, a developer of advanced electroplating and wet processing tools for microelectronics manufacturing, says that it has received a follow-on order for its Solstice GoldPro gold electroplating system from a leading microLED maker with global manufacturing sites.
MicroLED-Info is happy to announce the 2023 edition of The MicroLED Handbook. This book is a comprehensive guide to MicroLED display technology, industry and market. MicroLED displays are thin, efficient, bright and flexible and are on track to revolutionize the display industry. The handbook is now updated to January 2023 and lists recent developments and new companies, initiatives, products and research activities.
Reading this book, you'll learn all about:
MicroLED technology, materials and production processes
How MicroLEDs compare to LCDs and OLEDs
What are the challenges towards commercial production
LED technology and manufacturing processes
MicroLED driving and full-color architectures
The MicroLED displays currently on the market
The book also provides: The book also provides: an in-depth guide to MicroLED Microdisplays, potential applications of MicroLED displays, a comprehensive list of MicroLED companies, an introduction to other emerging display technologies (such as quantum dots and OLEDs), a current overview of the MicroLED market, market and industry forecasts and much more!
LG Business Solutions launched its MAGNIT MicroLED TVs in India, and the company shared a nice launch-event video showing the first installation in India for the event:
LG's latest microLED TVs are the LSAD series, for which the main size is a 136-inch 4K display. The TVs offer 2000-nits and 120Hz, and are powered by LG's latest Alpha 9 AI-enhanced processor and the company's own webOS smart TV platform.
We're happy to interview ClassOne Technology, as part of our series of interviews with MicroLED Industry Association members. ClassOne develops and sells high-performance electroplating and wet processing systems for the manufacture of advanced microelectronics, for both R&D and high-volume fab environments. For the microLED industry, ClassOne offers its Solstice single wafer electroplating and wet process platform, in addition to its reactor technology for the industry.
Q: Can you introduce your company and technology?
Joe Gaustad, Product Manager, ClassOne Technology: At ClassOne, our mission is to deliver the world’s highest performing and most elegantly designed electroplating and wet processing systems for the manufacture of advanced microelectronics. Engineered for maximum efficiency and flexibility on the manufacturing floor, our systems offer a comprehensive range of electroplating and wet process solutions validated, tested, fab proven, and designed for top performance in both high-volume and R&D fab environments.
Specialized Korea-based LED developer Lumens announced that it has developed a Monolithic RGB epitaxial wafers for micro-LED display production. The new technology stacks the three color LEDs on on top of the other on the wafer.

A stacked microLED architecture improves the performance, while also making the transfer process more productive. The company says that its design will offer a dramatic reduction in the production costs - especially the transfer process, which is reduced to a third (in terms of number of transfer steps), while also doing all the process from a single wafer.
Aixtron launched a new fully-automated production system, the G10-AsP, targeting the microLED and laser markets. The company says that the G10-AsP ,the first system to offer a fully automated process, enables the highest throughput of its class with uniformity and defect levels never seen before.
Aixtron says that this system will allow, for the first time, the mass production of 10um (or lower) microLED chips, with high performance. The G10-AsP offers a 200mm AsP Batch reactor and comes with In-Situ Cleaning and an automated cassette-to-cassette (C2C) wafer loading.
The first webinar is focused on quantum dots (QD) technologies. In this webinar, we hope to learn more about the state-of-the-art QD and color conversion R&D, with a focus of course on applications in the microLED industry. The event will take place on March 6th, and here's the agenda:
Prof. Dmitri V. Talapin: world-leading QD researcher from the University of Chicago, who will update on the latest QA research
Nanosys: leading QD developer (speaker TBD)
GE: "Phosphor converted miniLEDs and microLEDs based displays" (MicroLED Association member)
QustomDot: "InP-based quantum dots for color conversion in microLED applications" (MicroLED Association member)
