Seoul Viosys starts mass production of rare-earth-free white LEDs
Original: Seoul Viosys begins mass production of rare-earth-free white light emitter, with chips as small as 10µm
South Korean LED maker Seoul Viosys has begun mass production of a white light emitter that requires no rare-earth phosphors, using chips as small as 10 micrometres. The move reduces dependence on rare-earth materials, a supply chain dominated by China and under strain from export restrictions, and could interest display and lighting manufacturers seeking alternatives.
Why now: Rare-earth supply concerns are pushing companies to announce alternatives, making this production milestone timely.
