We present a stretchable electroluminescent (EL) sound display that simultaneously delivers multicolor light emission and sound generation, designed for next-generation interactive textile platforms. To overcome the conventional trade-offs between mechanical stretchability and optical performance, we employ transparent ionogel-based electrodes and a high-permittivity composite layer comprising Ecoflex, Triton X, and inorganic phosphors. This material combination enables the device to maintain high brightness and clear acoustic output under various mechanical deformations. Moreover, we demonstrate a pixelated textile display capable of visualizing letters and patterns in diverse colors while emitting sound in sync. This multifunctional system represents a new direction in wearable human–machine interfaces by seamlessly integrating light, sound, and flexibility into a single textile-based platform.
