Seoul Viosys, an advanced opto-semiconductor solutions company and an affiliate of Seoul Semiconductor, has once again secured the No.1 global market share in the UV LED sector for 2024, marking its sixth consecutive year at the top (TrendForce 2025).

This milestone is not a one-time success, but rather a reflection of Seoul Viosys’s sustainable market dominance.

The company leads the UV LED market with its independently developed technology, "Violeds," offering innovative solutions across industries including sterilization, disinfection, skin rejuvenation, and air and water purification. With over 6,000 technology patents, Seoul Viosys has established a solid competitive edge in the industry.

This continued achievement reinforces Seoul Viosys’s position as a global leader in the opto-semiconductor sector, and the company will continue to expand its influence worldwide.

Company Overview – Seoul Viosys
Seoul Viosys is a specialized provider of UV LEDs, next-generation 3D sensor/laser light sources such as VCSEL (Vertical Cavity Surface Emitting Laser), and WICOP Pixel solutions for displays. Founded in 2002, the company currently holds the No.1 global market share in the UV LED sector. In collaboration with its parent company Seoul Semiconductor, Seoul Viosys has engaged in over 30 years of opto-semiconductor R&D, covering the full spectrum from ultraviolet (UV) to visible light and infrared (IR) (200nm–1600nm), backed by a robust portfolio of over 6,000 patents.

Its signature UV LED technology, "Violeds," delivers sterilization (UVC), skin regeneration (UVB), air and water purification, insect control, and plant growth solutions by precisely optimizing light wavelength, angle, distance, duration, and intensity—without using harmful chemicals. In 2018, the company acquired RayCan to secure next-generation VCSEL technology for applications such as facial recognition and autonomous driving, and began full-scale mass production. In January 2020, it launched the differentiated WICOP Pixel, a single-pixel RGB solution poised to transform the display market.
