Researchers from King Abdullah's University of Science & Technology (KAUST) in Saudi Arabia developed GaN and InGan red microLED devices that are highly efficient.

The researchers managed to increase the efficiency of their previous design by a new chemical treatment that removes damages at the microLED sidewalls (created during the fabrication process) and also retains the high crystal quality at the InGaN and GaN sidewall interfaces.

Omdia published a very interesting article, detailing the company's view on the microLED market - including its latest market forecast

Omdia sees 5 million microLED display shipping in 2025, which the company says will generate $7 billion in revenues. In 2027, the market will grow to over 11 million units. Omdia lowered its forecast from 2020 (back then it projected 16 million display shipments in 2027).

Last week we reported that Ennostar Incorporation (formed by a merger of Taiwan's Epistar and Lextar in 2020) demonstrated a 10.6" transparent microLED display at Touch Taiwan 2021. We now have more information on Lextar's new display prototype.

Micro-LED and mini-LED developer Rohinni announced that the company has developed a new design for its miniLED composite bondhead, which now allows multiple bondheads to run in parallel. Rohinni says it has been able to accelerate its miniLED deposition speed 14X compared to 'competing technologies'.

With the new system, Rohinni demonstrated >99.999% placement yield and scalability at speeds greater than 100 die per second.
