This is getting a little crazy.
A decade ago you needed two guys to manhandle a 55-inch LCD or (particularly) a plasma panel into place on a wall mount.
Now we learn, via OLED-info, that LG has shown off in DS. Korea an OLED 55-incher that weighs all of about 5 pounds and is a 1/2 inch thick. In metric, 1.9 kg and 0.97 mm thick.
The thing sticks to walls using magnets, which will make people in the hallways of mount companies like Chief and Peerless mutter something along the lines of, “Oh, crap.”
The new panel is less than a quarter of the depth of LG’s existing flagship 55-inch OLED panel, which is a positively beefy 4.3 mm thick (something like 1/8 inch).
I couldn’t dig up anything about when/if this kind of unit will be commercially available, or the magical “How Much?” question. For the latter, the correct answer is undoubtedly: “Lots!”
