They're best seen here if you can't make a London trip to gawk at the clear 55-inch displays between October 7th and 28th. Beyond their use as attention-grabbing commercial displays straight out of a futuristic movie, LG and Harrod's are also teaming up to highlight the latest OLED TV models, all of which feature the Korean company's panels.

We've seen a few implementations of see-through LCD technology in refrigerators and other items, and in theory OLED should be even better with its individually-backlit pixels. However, just as we've seen in TVs for the home, prices for OLED haven't quite dropped to match LCD and that's probably just as much of a reason why these exhibitions are still so few and far between.
