Seoyon E-Hwa and Wooree E&L have jointly obtained two Korean patents covering LED composite material technology, marking the first time the companies have pursued a co-owned patent filing in Korea.
The inventions disclose a structure in which multiple LED chips are mounted along a pair of parallel, surface-treated wire electrodes and then encapsulated with a protective layer to form a unified composite LED material. The technology effectively integrates LED chip–electrode interconnection and pre-packaging material formation, enabling lightweight, durable, and uniformly spaced LED arrays.
According to Seoyon E-Hwa's regulatory filings, KR2785980 relates to a composite LED material that mounts mini or micro LED chips onto metal wires to improve durability and reduce weight, while preventing chip detachment or damage during bending. The company notes that the structure allows LEDs to emit light at regular intervals and can be manufactured efficiently through a simplified process. For KR2849455, the company further highlights that the design supports roll-to-roll processing, enabling scalable and efficient mass production.
