Frankly, I was as surprised as anyone to learn that the coolest concept TV of last year's CES -- an OLED TV that can roll up like a poster to disappear inside a trim, little box -- is reportedly going on sale in 2019.

Why? Aside from the obvious answer of "because they can," a roll-up TV is truly useful. As I wrote last year: "One of the worst things about big-screen TVs is the necessity for a massive swath of black plastic taking up a chunk of wall when it's turned off. With a rollable TV that's no longer an issue, and that practicality is the main reason I think LG Display will want to perfect this technology and help manufacturers bring it to market sooner rather than later."
