Sony may be winding down its OLED operations in Japan, but over in South Korea OLED is big business for LG—with news coming in today saying they're investing a whopping $225.7m into tripling production. But who's buying?

I saw LG's 15-inch OLED last night at an event, and it was remarkably beautiful—particularly because the last time I'd seen it had been on the CES show floor, obscured by eager show-goers. It's a stunning technology, but is let down firstly by size restrictions and secondly the high cost of them.

This won't be the case forever though, and I look forward to seeing some properly-sized OLED TVs that can replace my 42-inch at home. LG's apparently releasing 20-inchers this year, 30-inchers in 2011, and 40-inchers the year after—so looks like I've got another couple of years to wait out first. [Reuters]
