文摘Intrinsically stretchable light-emitting diodes(LEDs)are foundational components for next-generation free-form displays.Here,we present recent advances in electroluminescent materials for intrinsically stretchable LEDs,including molecular plasticizer-light-emitting polymer blends,elastomer-lightemitting polymer integration,thermally activated delayed fluorescence polymers,and inorganic semiconductor nanocrystals-elastomer composites.Critical challenges—improving luminous efficiency,stability,patterning,and developing stretchable electrodes and transport layers—are discussed,providing clear pathways toward practical applications.
