Seoul Biosys Begins Production of Rare Earth-Free White Micro LEDs

Seoul Biosys has started mass production of white micro LEDs using its WICOP technology, which generates white light without rare earth elements or separate packaging. This technology allows for the creation of white light in chips smaller than 100µm. The first mass-produced product is a micro LED measuring 25µm x 10µm, with a light efficiency of approximately 100 lumens per watt. The company aims to reach 200 lumens per watt within the next two years. This could reduce manufacturing costs and environmental impact by eliminating the need for rare earth elements and traditional packaging materials. Seoul Biosys is planning to broaden its technology applications beyond white light in the future. The micro LED display market is expected to grow from $10.54 million in 2023 to approximately $6.8 billion by 2032, primarily in smart glasses and ultra-small displays.
