Ultra-Stretchable, Transparent Organic LED Device
Added Sep 25, 2013 | Rate View top rated
Researchers from UCLA's Henry Samueli School of Engineering and Applied Science have developed an elastic, transparent organic light-emitting device (OLED) that can be repeatedly stretched and twisted at room temperature while remaining lit and retaining its original shape. The researchers stretched and re-stretched it 1,000 times - extending it 30 percent beyond its original shape and size - and it still continued to work at a high efficiency. The OLED 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. The ultra-flexible OLED can also contain multiple pixels, rather than just a solid block of light, which could pave the way for electronic displays comprising many thousands of pixels.
