Forget buying a clunky wall mount for your TV... what if you could stick it up like a fridge magnet? LG Display is hoping you'll do just that. The company has unveiled a 55-inch OLED screen that's so thin and light (0.04 inches and 4.2 pounds) that you can put it on your wall using a magnetic mat. The design doesn't exactly leave room for much else -- you'd probably need a breakout box for TV functions -- but it raises the possibility of big-screen sets that easily blend into your living room's decor. Unfortunately, LG isn't saying if or when this panel will translate into a real product. You'll most likely have to settle for the company's more conventional OLED TVs in the short term, including a giant 99-incher due this year.
