Abstract

This paper presents the development of intrinsically stretchable organic light-emitting diodes (is-OLEDs) that overcome performance limitations of traditional is-OLEDs caused by solvent incompatibility and lamination fabrication. A sequentially coated is-OLED with a morphology-sustainable electron transport layer (is-ETL) and a highly stretchable metallic cathode is fabricated. The resulting is-OLEDs achieve a maximum luminance of 3151 cd m⁻² and current efficiency of 5.4 cd A⁻¹, maintaining 80% luminance after 300 stretching cycles at 40% strain. This approach offers a promising path towards durable and efficient soft electronic devices.
