Washington, Sep 24: Researchers have developed a transparent, elastic organic light-emitting device (OLED) that is stretchable, foldable, and could help revolutionise the electronic display industry.
The OLED that researchers from UCLA’s Henry Samueli School of Engineering and Applied Science have developed can be repeatedly stretched, folded and twisted at room temperature while still remaining lit and retaining its original shape.
The new ultra-stretchable OLED material developed at UCLA could lead to foldable and expandable screens for new classes of smartphones and other personal electronic devices; electronics-integrated clothing; wallpaper-like lighting; new minimally invasive medical tools; and many other applications.
Qibing Pei, a UCLA professor of materials science and engineering and principal investigator on the research, said that along with the development of stretchable thin-film transistors, they believe that fully stretchable interactive OLED displays that are as thin as wallpaper will be achieved in the near future.
The material has a single layer of an electro-luminescent polymer blend sandwiched between a pair of new transparent elastic composite electrodes.
These electrodes are made of a network of silver nanowires inlaid into a rubbery polymer, which allows the device to be used at room temperatures. All of these layers are fully stretchable, foldable and twistable. The new material can also be fabricated in a relatively simple all-solution-based process.
The research has been published online in the journal Nature Photonics. (ANI)
