Researchers from Korea's KAIST institute, in collaboration with colleagues from the University of Chicago and Suzhou University in China, have developed a new stretchable OLED electrode technology that enables higher performance under stretching conditions.
To enable this high performance (brightness) stretchable OLEDs, the researchers developed a hybrid liquid metal cathode. The electrode was deposited by stacking thin layers of liquid metal, and slight etching on the top layer.
The researchers say that in a normal condition, the electrode behaves like a regular metal electrode, but when stretched, the lower-layer particles absorb all the impact, and the whole electrode retains its high performance.
