T ony Chen is a Taiwanese billionaire best known for co-founding Largan Precision, a global leader in the manufacturing of optical lens modules for smartphones and cameras. He established the company in 1987 alongside his business partner Scott Lin, and together they transformed it into a critical supplier for major technology firms, including Apple. Under his early leadership, Largan Precision captured a commanding share of the global market, reportedly claiming a third of the industry's volume.

Chen served as the company's chairman for many years, guiding its strategic direction during the smartphone boom that fueled its massive growth. He stepped down from the chairmanship in 2013 and eventually retired from the board of directors in 2022, passing the torch to the next generation. Despite retreating from daily operations, his founding stake in the company remains the primary source of his substantial wealth, as Largan continues to dominate high-end lens manufacturing.
