Porous-GaN material platform developer Porotech has demonstrated a full-color microLED microdisplay, made from the company's GaN LEDs. The company says that this is the world's first public demonstration of such a display.

The display is made using the company's DynamicPixelTuning technology, that makes it possible to create full-color or tunable-color monochrome displays using identical pixels from a single wafer. The company's PoroGaN material allows a modulated current to be leveraged to emit visible light covering the entire color spectrum on a single microLED chip.

We're happy to interview ASMPT, as part of our new series of interviews with MicroLED Industry Association members. ASMPT (formerly ASM Pacific Technology Ltd.) was founded in 1975 and is a leading global supplier of hardware and software solutions for the manufacture of semiconductors and electronics. 

Q: Hello! Can you introduce your company and technology?

We are a leading global supplier of hardware and software solutions for the manufacture of semiconductors and electronics. ASMPT is the only company in the world that offers high-quality solutions for all major steps in the electronics manufacturing process: from equipment to multi-factory-level automation concepts for smart manufacturing. From carrier for chip interconnection, to chip assembly and packaging, to Surface Mount Technology (SMT), ASMPT’s offerings encompass wafer deposition and laser grooving, to the various solutions that shape, assemble and package delicate electronic and optical components into a vast range of end-user devices; these include electronics, mobile communications, computing, automotive, industrial, LED & displays.

We have participated in Mini and Micro LED development since 2016. Our core technologies in Micro LED, mass transfer and mass bonding for Micro LED, have been well developed and successfully performing in customer sites worldwide.

Belgium-based microLED microdisplay developer MICLEDI announced a partnership with AR glasses developer Kura Technologies to co-develop AR glasses. The two companies have been working together for over a year with MICLEDI providing Kura early access to its displays.

Kura says that its proprietary architecture from the chip level up, and its AI-generated optics these next generation glasses will offer groundbreaking performance capabilities.

Belgium-based microLED microdisplay developer MICLEDI announced a partnership with IQE, a supplier of compound semiconductor wafer products and advanced material solutions to the global semiconductor industry, to develop microLEDs for AR products.

Under this agreement, IQE will provide MICLEDI with a 200mm (8-inch) platform to scale and commercialise its technology to achieve high-volume production for red microLEDs. This geometry allows for compatibility with both standard 200 mm and 300mm silicon foundries, which enables the partnership to deliver economies of scale.

Towards the end of 2020, Samsung announced it's first "consumer" MicroLED TVs that adopt small microLED chips (this followed its professional/commercial TVs that used larger chips and are already in production for several years). These smaller TVs were scrapped later in 2021, and then Samsung further delayed its plans in April 2022 and did so again in June 2022, due to technical issues.

According to the latest report from Korea, Samsung finally started to produce 89-inch LTPS microLED TVs. Its larger 101-inch and 114-inch models, however, are still not in production.
