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!
That being said I'm not expecting to see one at a price I'd want to pay in the next 15 years
Roll-up posters hung somewhere else that roll out to cover the same area?
A bookshelf. I have a bookshelf on the wall doing what bookshelves do. And then I'll hang the TV 'roll' in front of one of the shelves and pull it down in front of the bookshelf when I want to use it.
The ‘standard’ oleds (which all look amazing) are going to the standard soon. The quality of the picture, blacks especially, is instantly noticeable.
