Despite the low seasonality in the LED industry, Seoul’s strong performance in the first quarter will lead to a higher expectation for financial results of the fiscal year 2021. The financial results including revenues and profit analysis will be released at the end of April.

“Manufacturing transition to Vietnam, which has been started from 2017, entered the stabilization stage. Seoul expects further profitability for the year by delivering superior cost advantage and pricing competitiveness. We also expect exceptional revenue growth in the 2nd half as mass production of mini LEDs, one of the core next generation display technologies, starts,” 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.
