KAIST researchers develop a white OLED device on a fabric substrate
Researchers from the Korea Advanced Institute of Science and Technology (KAIST) developed a white OLED device that can be deposited on thin fabrics. The researchers say that this is the world's first such device, as previous white OLEDs, made using a tandem structure, could not be bent on fibers.
For the new device, the researchers developed a single white light-emitting layer. The brightness of the device is up to 700 nits, with an efficiency of 10 candelas per ampere.
