According to Digitimes, some "industry sources" say that LG Electronics dropped its OLED TV sales target for 2015 from 5 million TVs to only 800,000. LG still expects OLED to become the mainstream TV display technology in the future.
While it ain't good to hear that LG is less optimistic, it should also be noted that the 5 million sales target (which indeed we heard from one LG executive) was never realistic. LGD's upcoming Gen-8 M2 OLED production line (which is still not online) will have a monthly capacity of 26,000 substrates - or about 150,000 55" panels. Assuming 100% yields (which is not achievable, obviously) - that's only 1.8 million panels in a year, assuming full production capacity is achieved on January 1st.
Even if we add up the smaller capacity pilot line, and even if LG starts producing smaller-sized OLEDs (actually currently it seems that at least some of the capacity will actually go towards 65" and 77" panels), it's highly unlikely that will be able to produce 5 million OLED panels next year.
Keep in mind that LGD also supplies OLED panels to other companies, not just LGE. LGD supplies OLEDs to China's Skyworth, Changhong and Konka. According to earlier reports (and cited again in this Bloomberg article) LGD is in talks with both Sony and Panasonic for OLED supply. A couple of weeks ago Panasonic showed 65" 4K OLED TV prototypes that use panels made by LGD.
