LG just made the first curved 3D OLED screen. I just saw a crazy setup of three of these 55-inch beauties aligned side-by-side into a perfect cinematic curve. The effect is very dramatic. This could be the whole reason 3D and curved OLED exist.
As we saw with the huge curved OLED that Samsung showed us earlier today, these wavy displays are basically made for watching epic and atmospheric content. That's true with LGs OLED with 2D content and when you throw on a pair of shades and watch 3D content like planets in space and weird intergalactic flying jewels, you get sucked in.
