Chengdu Topway has successfully produced and delivered China’s first domestically developed 8.6th generation Common Metal Mask (CMM) to a leading client. This marks a significant breakthrough in OLED core material production, addressing a critical technology gap. The 2620 x 2290mm CMM is designed for medium-to-large sized displays and enables lower production costs. Overcoming challenges in exposure, etching, and tension control, this achievement reduces reliance on foreign technology and strengthens China’s advanced display ecosystem.
