Seoul Biosys Begins Production of Rare Earth-Free White Micro LEDs
Seoul Biosys has started manufacturing rare‑earth‑free white micro‑LEDs, aiming to reduce reliance on scarce materials. The new chips use a silicon‑based substrate and a gallium nitride layer, offering high brightness and energy efficiency. The company plans to supply the growing demand for compact lighting in displays and automotive applications. This move could lower costs and improve supply chain resilience.
