China Star Optoelectronics Technology (CSOT) is reportedly advancing in its AMOLED 4.5-Gen R&D line. The company now expects to start trial production by the end Q1 2013.
The same report suggests that BOE Display is also progressing in its 5.5-Gen AMOLED line in Ordos - with hopes to start mass production in Q4 2013. This is earlier then previously estimated (2014). BOE's fab will be able to produce 54,000 monthly substrates (both LCD and AMOLED, on LTPS).
Last month it was reported that BOE is struggling with low AMOLED yields, and is seeking to collaborate with Taiwanese OLED makers on R&D.
