[Asia Economy Reporter Minji Lee] QS I, a specialized small and medium-sized enterprise in laser diodes (LD) and materials and components, announced on the 15th that it recorded an operating profit of 1.9 billion KRW in the third quarter, turning profitable compared to last year. Net profit reached 1.2 billion KRW, and sales grew 45% during the same period to 7.2 billion KRW. The operating profit margin significantly improved from around 8% to 26%.

The cumulative sales for this year stand at 23.6 billion KRW, operating profit at 3.3 billion KRW, and net profit at 3.8 billion KRW. The company stated, "By internalizing all areas from LD design to packaging, the operating profit margin increased," adding, "The growth in sales of existing high value-added products such as Medical, Sensor, and laser beam printers also had a significant impact." Additionally, sales of new products, including sensors for metaverse (VR) devices, which recently surpassed 1 million units supplied, are estimated to have begun in earnest.

QS I has succeeded in domestic localization of InP (Indium Phosphide) semiconductors, essential for 6th generation (6G) communication and quantum computers, as the only company in Korea through national research projects. Currently, it is developing the domestic production of red elements for micro LED, considered the next-generation display technology.
