Seoul Viosys
Korea-based Seoul Viosys develops and produces LEDs of all wavelengths, and operates its own LED (and microLED) epiwafer foundry.
In collaboration with its sister-company Seoul Semiconductors, Seoul Viosys develops its WICOP mp MicroPixel technology, which is an RGB microLED vertical pixel. The company demonstrated several prototypes and published a roadmap in May 2023. The company is mostly targeting the signage market.

Seoul Viosys unveils a new microLED microPixel technology called WICOP
LED developer Seoul Viosys announced a new technology called WICOP mp, that combines the company's no-wire, no-package WICOP tech with microLEDs to create so-called micro Pixels.
The company says that its WICOP technology makes it possible to populate brand-new semiconductor chips into a general manufacturing process directly without modification. Seoul Viosys says that using WICOP mc microPixels enables higher efficiency (as there's no efficiency degradation) and high density displays (up to 2000 PPI)
Seoul Viosys developed new microLED technologies, aims to release 30um chips in H2 2021
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 expects its first microLED revenue in Q1 2021
Seoul Viosys says that the company expects to receive its first microLED revenues in 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".
The idea is that these packaged colored pixels will be easier to transfer to the target substrate compared to the transfer of three different LEDs. The package itself does not contain any driver ICs.
