摘要
Stretchable organic light-emitting diodes(SOLEDs)have been the challenging class of OLEDs as they have limited processability to fabricate a design that can withstand external deformation.Herein,we demonstrated the highly efficient top-emitting geometrical stretchable OLED(GSOLED)by incorporating the prestretched elastomer with optical adhesive film.The experimental and theoretical characterizations verified the enhancement of device efficiencies 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.The full width at half maximum(FWHM)of 21 nm shows narrowband emission with a high current efficiency and EQE of 221 cd A^(−1) and 39.50%.This work marks a significant step forward,providing unprecedented insights into the factors influencing device performance in current and future material systems for stretchable organic light-emitting diodes.
