LG Display recently announced a major focus shift to OLED displays, with plans to invest $8.5 billion in OLED expansion in the next three years. Reports from Korea suggest that LG Display considers constructing a new 9-Gen (or 9.7-Gen, really, 2,950 by 2,500 mm) fab that will produce both LCD and flexible OLED panels.
Different reports, however, say that LG is more likely to add 8-Gen production lines and perhaps construct a 10-Gen OLED TV fab.
A 9.7-Gen substrate can be cut to eight 55" panels or 6 65" ones. This is similar to an 8-Gen fab but with much less wasted substrate area - which means more efficient production and thus cheaper panels.
I'm not sure if it's likely that we'll see such a large-substrate being used for flexible OLED production, as it seems that at least in the near future flexible OLEDs will only be used for small-sized panels. On the other hand LG Display is aiming to produce flexible and transparent OLED TVs by 2017...
LGD is currently producing OLED TVs in a Gen-8 fab (which will have a monthly capacity of 34,000 substrates by the end of 2015), and a smaller Gen-4.5 fab that produces plastic-based OLEDs - with a monthly capacity of 14,000 substrates. LGD already announced plans to build a new 6-Gen (1500x1850 mm) flexible OLED fab in a $900 million investment.
