The LG “Wallpaper” TV is astonishingly thin… apparently 0.15 inches for a TV 57.1 inches by 32.5 inches. It’s also a little pricey, but, yikes. Look at it. The “newspads” shown in “2001” can’t be too far off.
Here’s a vid of the technology from nearly three years ago showing the screen (a smaller, lower-rez prototype) actually being rolled up:
This sort of looks like soon a 4K TV screen will be actually *printed.* Think of a TV screen that rolls up like an old movie projector screen… say, a tube six feet long containing a TV ten and a half feet wide, rolls up into a tube two or three inches in diameter, store it away when not in use, cover a whole wall when you want it. or further down the line, actually cheap enough to use it as *actual* wallpaper. Cover your ceiling with it, mount high rez cameras on your roof looking up, show the day/night sky.
