LG Display says that they will begin production in their 8.5-Gen plant in July, making 8,000 monthly substrates - or about 48,000 55" OLED TV panels. It's possible that this assumes 100% yield - and in any case this is more panels then planned. LG plans to invest 4 trillion Won (around $3.5 billion) in OLED production this year, and plans for 2013 will only be made during in the third quarter - LG wants to see the market reaction.
LG's 55EM9600 is a 55" Full-HD OLED TV featuring 100,000,000:1 contrast ratio and fast response time (1,000 times faster than LCD according to LG). The panel is only 4mm thick, and the whole TV weighs just 7.5Kg. The TV is based on LG Display's Oxide-TFT white-OLED with color filters (RGBW) OLED panel.
LG plans to sell 200,000-300,000 units in 2012 and about 2 million units in 2013. They didn't decide on a price yet, but according to DisplaySearch it will probably be around $8,000 (and will drop to around $4,000 in 2013).
