Researchers at the University of Tokyo have developed a new kind of OLED display that can stretch and deform like rubber.
The team demonstrated a face-shaped display showing changing expressions, and a spherical screen to show weather information.
Takao Someya, an electrical-engineering professor, and his colleagues make a stretchable display by connecting OLEDs and organic transistors with a new rubbery conductor. The researchers can spread the display over a curved surface without affecting performance. The display can also be folded in half or crumpled up without incurring any damage.
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.Combined with printable transistors and OLEDs, this could pave the way for rolling out large, cheap, wearable displays and electronics.
