Digitimes says that Japanese OLED makers (such as SK Displays, TM Display and Hitachi) have already begain mass production of AMOLED displays, while Taiwanese companies are postponing their schedules and will not start volume production until 2005.
There are 15 AMOLED production line planned in Taiwan, Japan and Korea for 2005 according to Digitimes. Nine of these lines belong to Japanese makers. In Taiwan, the leading player seems to be RiTDisplay. The company have been showing AMOLED samples in June 2004 but they will not start mass production in 2004 as originally planned - they postponed it to 1Q 2005 due to low yields.
AU Optronics also plans AMOLED mass production in 1Q 2005. Chunghwa Picture Tubes (CPT) will convert an existing 3-Gen fab to a-Si AMOLED production. Chi Mei Optoelectronics (CMO) plans to start making LTPS AMOLED in 2005.
