A few days ago we reported that Tianma developed a 4.5" Full-HD AMOLED panel. Now we hear from a trusted source that this report was in fact wrong - the company did not develop any such panel.
When I talked to Tianma at SID they said that the current plan is to first focus on LTPS LCD production, with an aim to achieve mass production in 2013. Only then they will start adapting the process for OLED production, with mass production to start in 2014. If last week's report was wrong indeed, then I assume the company still aims for OLED mass production in 2014.
Tianma has a pilot 4.5-Gen AMOLED fab in Shanghai (it was reported in 2010 that the pilot line's cost was $72 million and the Chinese government helped with $40 million in funding). The pilot fab is able to produce around 1,000 glass substrates in a month. Tianma's prototype panels shown at SID (in June) used a direct-emission architecture and an LTPS backplane.
