Researchers from Kyung Hee University in Korea have designed highly efficient stretchable OLED devices by incorporating the prestretched elastomer with optical adhesive film.
The researchers say that the so-called Geometrical Stretchable OLED (GSOLED) device enhances the efficiency of the OLEDs with the light extraction phenomenon brought by nanowavy corrugated structures. Furthermore, GSOLED shows stability in stretchable conditions and displays narrower emission spectrum with improved color purity.
GSOLEDs offers narrow emission (full width at half maximum of 21 nm) coupled with a high current efficiency and EQE of 221 cd A−1 and 39.50%.
