AU Optronics is demonstrating several display at Touch Taiwan 2023, including an interesting new laptop microLED display. The display is a 14.6" 2560x1440 (QHD, 202 PPI) foldable panel, that can reach a brightness of over 1,000 and a bending radius of 4 mm.

In addition to this display AUO is showing its 17.3" transparent microLED prototype.

Korea-based Top Engineering developed and launched a new microLED chip inspection tool, offering non-contact EL inspection.

The equipment can analyze LED chips directly on the epiwafer, and inspect thousands of microLED chips at the same time. The tool can use non-contact EL inspection on vertical microLED chips.

In a new and interesting analysis, the Korea Times suggests that the US is considering adding display technologies, mostly next-gen displays OLEDs, to the list of restricted technologies and may ask Japan and Korea to stop selling materials and equipment to Chinese display makers. 

Apparently the US government is still debating over this decision. OLED displays are used in defense applications, but OLED displays, unlike semiconductors, can be replaced with LCDs without effecting performance much, which means that hurting China's OLED industry will not have a strategic effect on China outside of the display industry. China today is the world's leading display maker by volume, but Korea is still leading in OLED display production. This decision, if happens will have more economic implications than strategic ones. 

We're happy to interview QustomDot, as part of our series of interviews with MicroLED Industry Association members. QustomDot is an early stage company that develops quantum dots materials tailored for microLED display applications.

Hello! Can you introduce your company and technology?

Kim De Wolf, QustomDot's co-founder and CEO: QustomDot is a technology startup that specializes in the development of customized quantum dots for down-conversion applications. Quantum dots are semiconductor nanocrystals that exhibit unique optical properties, making them useful in areas such as displays, solar cells, and
biomedicine.

The MicroLED Industry Association (MIA), a cross-industry association created to accelerate the adoption of microLED display technologies and facilitate collaborations between companies in the MicroLED industry, is proud to announce The MicroLED Library.

This new platform is an extensive compilation of MicroLED datasheets, presentations, whitepapers and more. To date, it already curates content from various companies (including GE, Terecircuits, Radiant Vision Systems, CEA-Leti, eLux and more), some of which is available in several languages, and includes the MIA's own whitepapers.

The MicroLED Library is public and free for everyone to use. It will be continuously updated in order to remain a valuable resource for MicroLED information. You can access it here!

InZiv announced a new industrial-level microLED inspection system, called the REL. The company says that this new system provides unprecedented speed wafer-level EL testing of microLEDs. The REL system can rapidly obtain EL measurements on a microLED wafer, with up to 6 million LEDs in 1 hour.

The company's unique technology offers repeatable, high- accuracy measurements, with no damage to the device. The system is fully compatible with both vertical and flip-chip designs. InZiv says that the REL offers the most critical and reliable microLED inspection on the market, enabling the advancement of all microLED applications. The company is already working on its next-generation system, which will double the output.
