The MicroLED-Info newsletter (October 11, 2022)

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.

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.

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.

We have participated in Mini and Micro LED development since 2018. 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.

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.
