Seoul Viosys begins production of rare-earth-free white light emitter

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.

Seems the AI translation changed the name a bit as it is Seoul Viosys, at least according to their website https://www.seoulviosys.com/en

The article is riddled with AI errors (for example, the company's name is Viosys, not Biosys). Looks like the innovation here is the multi-wavelength LED, some kind of multiple-quantum-well thing maybe?

> 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. [1] https://pubs.usgs.gov/periodicals/mcs2026/mcs2026-gallium.pd...

Ooh, cool. I'd like me some luminous concrete please. I like these order of magnitude changes in common technology -- in this case, way smaller minimum size and more efficient per square nanometer -- the use cases language is a good reminder that the innovation part ("Look! This is cool!") often (usually?) precedes the most compelling use cases. I imagine this is like 20 years away from hitting consumer design, but I bet it'll be used for some cool stuff.

I wonder if we'll ever see nanotech xenon arc lamps.
