University of Tokyo researchers developed a new kind of OLED display, that can actually stretch and deform - like rubber.They showed one displays that is shaped like a face, and showing changing expressions, and another screen that is spherical and shows weather data. The OLEDs were produced by spraying a layer of carbon nanotubes with a fluoro-rubber compound to produce a stretchy, conductive material.

The current prototypes are 100 sq centimeters, and have 256 monochrome pixels. They can be folded at least a thousand times, with no decline in quality. They are working towards better resolution and color displays.

"In the future, displays that once had to be flat can be made spherical, or even moving," says Takao Someya, professor of electronic engineering at the University of Tokyo. "A human-shaped display could be used to show medical diagnosis data, and there are various other applications."
