LGD is still constructing its $650-million Gen-8 M2 OLED TV production line, but the company's CEO announced yesterday that LGD will invest a further 700 billion Won (over $788 million) to increase the capacity of that fab to 34,000 monthly substrates (up from 26,000).
It seems that LG is forecasting a rising demand for OLED TVs once their prices become competitive with LCDs (which should happen once the M2 is online). The company also wants to sign up more TV producers besides LG Electronics (they are currently supplying to China's Skyworth and Changhong, but reportedly they are in talks with Sony and Panasonic as well).
