While the news that Samsung might be coming out with a foldable TV  is no real surprise, the fact that they have applied for a patent sure is. 
According to the tech giants, they have filed a patent with the Korean Intellectual Property Office (KIPO) and United States Patent and Trademark Office (USPTO) for the foldable TV.
How Samsung plans to implement the TV is unclear, but analysts expect it to improve user convenience as you’ll be able to roll up TVs when they’re not in use. They could also be carried about when travelling so if the TV is large, you can just roll it up and carry it along.
“This rollable display device can be used for TVs, monitors, game devices, multimedia devices and so on,” says Samsung. “Displays in devices can be liquid crystal display (LCD) displays, light emitting diode (LED) displays and organic light emitting diode (OLED) displays.”
It's possible this may never see the light of day. Samsung reserves the rights to a lot of designs, names and components on a daily basis and only a small portion of them ever make their way onto the market.
But if it does, well it could turn out to be  fun innovation.
