Seoul Semiconductor closes in on second-largest LED maker ams OSRAM
South Korea-based LED maker Seoul Semiconductor Co Ltd says that it has narrowed the market share gap with global number-2 player ams OSRAM to just one percentage point, according to the ‘2024 Global LED Market Share Rankings’ issued by market research firm Omdia. Seoul Semiconductor was the only company among the global top three to sustain both revenue and market share, while industry leaders Nichia and ams OSRAM experienced significant revenue declines amid the slowdown in the LED market.

Seoul Semiconductor says that this is underpinned by its robust technological competitiveness, driven by its commitment to innovation even amidst global economic uncertainty. The firm has consistently invested over 10% of its annual revenue in R&D, resulting in a portfolio of more than 18,000 patents worldwide. In the last 20 years Seoul Semiconductor has won over 100 cases in patent litigation across eight countries.
In particular, Seoul Semiconductor’s proprietary ‘No-wire’ technology is a core component of micro-LED displays. The firm has won a patent litigation at the Unified Patent Court (UPC) in Europe, reinforcing the strength and exclusivity of its No-wire technology in the next-generation display market.
According to Omdia, the micro-LED segment is emerging as a key frontier in next-generation display technology and is expected to grow into a market worth about US$80bn by 2040.
Seoul Semiconductor is the world’s third-largest global LED company, specializing in LED technology for over 30 years. Seoul Semiconductor spans industries including lighting, automotive, IT (such as backlighting), while its subsidiary Seoul Viosys specializes in micro-LED, UV, sensors, and datacoms.
Some of the technologies developed by Seoul Semiconductor include the world’s first no-wire LED technology WICOP, the SunLike LED which replicates the natural sunlight spectrum, the high-voltage LED Acrich, the ultra-bright Pola LED (10 times brighter than conventional LEDs), the RGB one-chip micro-LED WICOP Pixel, and UV sterilization technology Violeds.
