Tianma says they chose Lotus XG Glass because of the advanced properties of the glass. The company’s LTPS line is located in Xiamen, China, and has a capacity of 30,000 TFT modules, and more than 30,000 color-filter modules per month. It is the first Gen 5.5 LTPS line in China.
Tianma has a pilot AMOLED production fab in Shanghai. Back in 2012 the company was showing two AMOLED prototypes, a 3.2" (320x480) and a 12.1" (1280x800). Those are direct-emission (side-by-side) panels built on an LTPS substrate. The panels were produced at Tianma's pilot 4.5-Gen AMOLED fab in Shanghai. It was reported in 2010 that the pilot line's cost was $72 million (the Chinese government helped with $40 million in funding) and it is able to produce around 1,000 glass substrates in a month.
