Hair-thin OLED Fibers

A South Korean team of researchers has fabricated highly efficient organic light-emitting diodes (OLEDs) on an ultra-thin fiber.

When a button is pressed, a 65-inch display turns on. The display can be stored as being rolled down into a small tube.

This image that exactly mimics real nature features on an ultralarge screen made with 246 88-inch OLED panels.

Technologies for the next-generation high-end OLED displays have been evolving very fast.

A research team at South Korea's state-run Korea Advanced Institute of Science and Technology (KAIST) has successfully built OLED on fiber thinner than a human hair.

A thread is dipped into a luminous substance gently and slowly.

A thin and even OLED layer is created on the surface of the thread.

A light turns on when the OLED fiber is charged.

"We've found that the OLED fibers, based on the conventional OLED, can be woven into the fabric without any performance degradation."

The low-cost, durable fiber-based OLED is expected to open a way to commercialize a wide range of wearable devices.
