Han Jong-Hee, a senior executive at Samsung Electronics who played a pivotal role in transforming the company’s television business, passed away on Tuesday at the age of 63. He died in a hospital after receiving treatment for a heart attack, according to the company.

Han, who joined Samsung in 1988, dedicated most of his career to TV-related divisions, helping Samsung become the world’s leading TV manufacturer. In 2022, he was appointed co-vice chairman and CEO, overseeing the consumer electronics and mobile device divisions.

Samsung, a global technology giant, is renowned for its strength in both components and consumer products. The company maintains separate CEOs for its major business divisions, with one focusing on consumer electronics and mobile devices, and another overseeing its semiconductor business. Following Han’s passing, Jun Young Hyun, the CEO of Samsung’s semiconductor division, will assume Han’s responsibilities as the sole CEO of the company.
