Korea-based LED developer Seoul Viosys announced two microLED related breakthroughes developed together with researchers from the University of California, Santa Barbara (UCSB).

First of all, the researcher succeeded in developing blue and green micro LEDs with 1 μm diameter. Second, they have managed to overcome challenges of decreased EQE in red microLEDs at 70um. The EQE of the 70um red microLEDs have been increased by 150% compared to the company's previous designs.

Seoul Viosys says it is preparing to release 30μm one-pixel Micro LED products in the second half of 2021 and 10μm one-pixel Micro LED products in 2022.

Earlier this year Seoul Viosys said it expects to receive its first microLED revenues by Q2 2021. The company, together with Seoul Semiconductors, developed a new MicroLED technology, called Micro Clean LED that basically packages three separate LEDs (red, green and blue) into a single "one-single MicroLED pixel".



Sounds very promising. I hope

Sounds very promising. I hope it means smaller and cheaper microLED displays in the not-so-distant future?

However, it might depend a lot on which display manufacturers will work with which LED developers. A breakthrough in a lab is not worth much unless it gets used by a large consumer-grade device manufacturer.
