We got word from a senior manager from LG Electronics that says that while the 15" OLED TV's price hasn't been decided yet, it will be in the range of 2,500$-3,000$ in Korea (due to launch in November).

Obviously this is a lot of money for a 15" TV. But it's about the same as Sony's 11" XEL-1 (which still costs 2,500$ in the US), so you get almost 40% more screen for the same money. Also this is the price for Korea, hopefully it will be lower when it launches worldwide in 2010.

The 15" OLED TV will have a 1366x768 resolution, 100,000:1 contrast ratio and it'll be only 1.7mm thick.
