Seoul suggests revenue for the second quarter to be between KRW 320 billion and KRW 340 billion growing 19% to 29% YoY that indicates strong expectations for the full year. In April, Seoul reported that its LED package business ranked the third globally in 2020 surpassing Lumileds, a LED manufacturer in the U.S. according to Omdia, a global market research leader. Seoul expects to continue double digit growth this year to be positioning as a global top LED leader in the future.

Strong growth in the IT division as a beneficiary of the growing non-contact economy in pandemic era led to outstanding performance in the first quarter. IT division showed strong growth but automotive and lighting divisions recorded stable growth and performance as well. Manufacturing site transition to Vietnam started in 2017, also has stabilized and contributed to improved profitability.

“We have higher expectations for the second half as mass production of mini LEDs will lead to better results. We have been investing to capture new growth opportunities,” said an officer at Seoul. Seoul’s mini LED uses package-less WICOP products, the world’s first revolutionary technology directly mounting LED chips onto a substrate.
