GoKawiilSeoul Biosys starts mass production of rare earth-free white micro LEDs
Seoul Biosys announced on October 28 that it has begun mass-producing white micro LEDs built on its third-generation WICOP technology, which skips rare earth phosphors and conventional packaging. The initial product is a 25µm x 10µm chip delivering 0.015 lumens at roughly 100 lm/W efficiency, with a target of 200 lm/W within two years. The company says cutting rare earth materials and packaging components like silicone resin and lead frames could halve production costs.
GoKawiil's interpretation of the reporting above, not reported fact.
Removing rare earth dependency could insulate LED makers from supply and price volatility tied to those materials, which have been subject to geopolitical export controls. Omdia's forecast of the micro LED display market growing from about $10.5 million to $6.8 billion by 2032 suggests a significant commercial opportunity in smart glasses and ultra-compact displays that this technology could target.
- Seoul Biosys has started mass production of white micro LEDs without rare earth phosphors using WICOP packaging-free technology.
- First chips measure 25µm x 10µm with about 100 lm/W efficiency, targeting 200 lm/W within two years.
- Omdia projects the micro LED display market could grow from roughly $10.5 million to $6.8 billion by 2032.
