Seoul Semiconductor’s world’s first leading 2^nd generation technologies

The second generation LED technologies developed by Seoul have led to strong sales growth as well as obtaining permanent injunction and recall of infringing products sold by competitors in the U.S and European courts. WICOP, a technology announced by Seoul’s CEO Chung Hoon Lee in 2015 at the Intercontinental Hotel in Shanghai, is the world’s first technology to directly mount LED chips onto a substrate without packaging. WICOP is recognized as a revolutionary semiconductor technology and is essential for production of mini LEDs, and whoever plans to manufacture mini LEDs needs to obtain license from Seoul.

“The restructuring of the LED industry is nearing its end. Not only competitors even in the North America and Europe, but also mid-sized competitors in Japan, Korea, Taiwan and China are facing severe management difficulties. This has provided a lucrative positioning for Seoul to lead the industry with its differentiated 2^nd generation technologies to achieve sustainable growth,” said an official of Seoul Semiconductor.
