Electrical engineering researchers at the University of Tokyo have developed a flexible, stretchable OLED that acts like rubber. It doesn’t tear or break when stretched. They produce the material by spraying a layer of carbon nanotubes with a fluoro-rubber compound, which creates a rubbery, conducive material.
At 10-centimeters square, the current monochrome display prototype has a resolution of just 256 pixels and can apparently be folded about 1,000 times with out degrading, falling apart, or tearing. In short, our future may be filled with rubber bouncing balls that have OLED screens.
