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.
