High prices and size constraints are the current Achilles Heel of the OLED TV market, but nevertheless LG will reveal the largest retail version yet next month for an undisclosed price.

The 15-incher will officially debut at the IFA 2009 show in Berlin, LG execs told Reuters, after which it will sell first in Korea before making its way overseas sometime after November.

And better still, at least for OLED fans, is word that LG is also preparing a 40-inch OLED product in the "not so distant future." We probably don't have to tell you that this "product" will undoubtedly be "expensive." [Reuters]
