Seoul Semiconductor develops and commercializes light emitting diodes (LEDs) for automotive, general illumination, specialty lighting, and backlighting markets.

As the third-largest LED manufacturer globally, Seoul Semiconductor holds more than 18,000 patents, offers a wide range of technologies, and mass produces innovative LED products such as SunLike – delivering the world’s best light quality in a next-generation LED enabling human-centric lighting optimized for circadian rhythms; Wicop – a simpler structured package-free LED which provides market leading color uniformity, cost savings at the fixture level with high lumen density and allows design flexibility; NanoDriver Series –World’s Smallest 24W DC LED Drivers; Acrich, the world's first high-voltage AC-driven LED technology developed in 2005, includes all AC LED-related technologies from chip to module and circuit fabrication, as well as multi-junction technology (MJT); and nPola, a new LED product based on GaN-substrate technology that achieves over ten times the output of conventional LEDs.

The company’s broad product portfolio includes a wide array of package and device choices such as AC driven LEDs, high-brightness LEDs, mid-power LEDs, side-view LEDs, through-hole type LED lamps, custom displays, and sensors.

The company is vertically integrated from epitaxial growth and chip manufacture in it’s fully owned subsidiary, Seoul Viosys, through packaged LEDs and LED modules in three Seoul Semiconductor manufacturing facilities. Seoul Viosys also manufactures a wide range of unique deep-UV wavelength devices.
