LG unveiled a bendable 77" 4K OLED TV prototype a couple of days ago - this panel can change from flat to curved at the press of the button, allowing consumers to enjoy a single TV that can be both flat and curved. We finally got a video showing this interesting new prototype in action:
This is just a prototype, but LG actually plan to ship this TV to the US in late 2014 or early 2015. Samsung has their own bendable OLED TV at CES, by the way.
