Can’t tell if you are joking or not, but when I unboxed my tv and was able to hold it up with one hand, easily and bend and twist it...pretty f’ing cool. It attaches to the wall with clips and magnets.
Rolling it up is great for some people. My wife isn’t a huge fan of giant TVs taking up space. The less than a pencil thickness of the lg tv makes it cooler than most, but being able to put it away or move it so easily would be cool.
They are only going to get more flexible. Soon you will have displays on everything and walls that double as TVs.
The lg wallpaper tv is my favorite piece of tech I’ve ever owned...unless you go back to the NES/SNES!
