> WICOP 3 generates white light from gallium nitride (GaN) alone.
Gallium might be a problem.
"China accounted for 99% of worldwide primary low-purity gallium production.
The remaining primary low-purity
gallium producers outside of China included Japan and Russia. Germany, Hungary, and Kazakhstan ceased primary
production in 2016, 2015, and 2013, respectively.
Ukraine most likely ceased primary production in 2022.
Several new gallium production projects were announced including those in Australia, Canada, Greece, Kazakhstan, and the Republic of Korea."[1]
The price of gallium has increased by a factor of 10 in the last 10 years.
It's doubled since last year.[2] A huge new demand for gallium is going to be a problem.
What does the color look like? Producing light that falls within the white region of the CIE diagram is one thing… if it’s too yellow or too blue it could be an issue. Maybe that’s something that can be worked out over time.
> Seoul Biosys plans to broaden its technology applications to augmented reality (AR) displays and optical communication for artificial intelligence (AI) data transmission. They are also developing a method to transmit data using densely arranged micro LEDs around 10µm in size.
Can someone who is an expert on the topic comment about if the statement regarding AI is true and if so then by how much (and how big/small of a problem it is), or if the Company is suggesting it out of pure hype of AI mania.
> Market research firm Omdia projects that the micro LED display market revenue will grow from $10.54 million this year to approximately $6.8 billion by 2032, particularly in applications for smart glasses and ultra-small displays.
> The WICOP technology involves directly mounting LED chips onto substrates without separate wires or packaging. Seoul Semiconductor and Seoul Biosys have been developing ultraviolet (UV), blue, green, red, and infrared (IR) micro LEDs based on this technology, and have now expanded its application to include white light.
Fascinating results nonetheless even discounting AI use. Having half the price is insane, also 10.54 million seems incredibly small and 6.8 Billion is a little insane. Kinda wild to see such massive growth expected in such short amount of time.

IMHO, this is pretty transparently r&d for better? data transmission attached to the trend of the day that does a lot of data transmission. Where better is higher bandwidth, lower cost, etc.
AI is the current trendy thing, but better data transmission will always have applications.
I remember attending a "pitch night," at a local incubator, about nine or ten years ago, when crypto was the new hotness.
One of the pitches was for a fairly good nonprofit service. I thought it was a good idea. Sort of a "help people that help people" thing. I can dig that.
At the very end of the pitch, the last thing the young lady said, was "And we're looking at implementing blockchain technology in our service."
I don't remember exactly what the service was, but it clearly had no applications for distributed-key tech.
I think it probably cost her the backing. No one was fooled. I think someone told her that she had to mention blockchain, somewhere.
Fwiw korean doesnt have a ‘V’ sound/character at all, and the V/B switch is quite common on Korean words that come from English, like “video” in Korean gets written with ㅂ at the start, and sounds more like “bideo”. And the same character is used in the Korean/Hangul version of their written company name.
Yikes. We've changed the URL from https://www.ajupress.com/view/20261028171670308 (and banned that site). I replaced it with the article that Google returns for the title, which looks like it might be the original source, or at least closer to it.

Looks like the innovation here is the multi-wavelength LED, some kind of multiple-quantum-well thing maybe?
