Well, this is one time where words fail me, which is why I often just put a video here and just let the readers love it.
This is exactly what you thinking it is: a bendable screen. This footage comes to us from LG, and it is an 18-inch OLED display. It has a resolution of 1200 x 910, and someone can just roll it up.
Is this the way of televisions? Considering those big boxes on the shelf could be replaced by smaller tubes…I would welcome this era.
