AU Optronics (AUO) has spent NT$4.4 billion ($140.5 million) to acquire a 100% stake in its colour filter affiliate, Toppan CFI. AUO purchased a 49% stake in Toppan in 2006, a company that was established in Taiwan in 2001 by Japan’s Toppan Printing.
Toppan CFI has 4.5G, 5G and 6G facilities in Tainan and a 5G fab in Kaohsiung. Reports suggest that the investment in Toppan will help AUO increase its CF self-sufficiency to over 90%.
