LG introduced a TV-window: OLED T in the off state becomes completely transparent.

In addition, if you are tired of the gray reality, various visual effects can be added to the “window”, whether it be raindrops, flickering or fish floating in the air. The TV shouldn't be on sale anytime soon, but that's the direction LG plans to go in the future. A small step for the TV manufacturer and a big leap for the window revolution.
