Seoul Biosys Begins Production of Rare Earth-Free White Micro LEDs
Seoul Biosys has launched production of micro LEDs that emit white light without using rare earth elements, marking a significant advancement in display technology. Traditional white LEDs rely on rare earth-based phosphors, but Seoul Biosys's third-generation WICOP technology enables white light generation without these elements or additional packaging.
The first product, a 25µm x 10µm micro LED, generates 0.015 lumens in the white light spectrum and boasts an efficiency of around 100 lumens per watt, with a target of 200 lm/W within two years. By eliminating rare earth elements and traditional packaging materials like silicone resin, plastic, and lead frames, Seoul Biosys aims to cut manufacturing costs by half.
The company anticipates growth in the micro LED market, driven by applications in smart glasses and ultra-small displays, with revenues projected to increase from $10.54 million this year to $6.8 billion by 2032. Seoul Biosys plans to leverage its technology for AR displays and AI data transmission, with the third-generation WICOP products set to be supplied to major clients starting in the fourth quarter.
