We've heard of many types of wearable devices, now, researchers at the South Korean science university KAIST say they've developed a fabric that can display images.
It's made of a fiber dipped in phosphorescent OLEDs, just like those found in a TV screen, that lights up with an electrical charge.
The advantage of this technique is that it's five times more energy-efficient than existing OLEDs and produces a bright picture.
The research team said this technology could soon be used in various fields like medicine and security.
