Multifunctional displays are under rigorous investigation as human-machine interfaces due to their unprecedented functionality in a compact design. However, their application has been limited to visualizing mechanical/electrical signals with light. Herein, we present a stretchable high-resolution multicolor synesthesia display that can generate synchronized sound and light as input/output sources through transfer-printing. The transfer-printed dielectric composite results in a display with enhanced optical and sound-generation performance. Owing to the device's intrinsic stretchability, the synesthesia display can maintain stable operation under both static and dynamic deformations, ensuring sound remains undistorted relative to the input waveform. User-interactive synesthesia displays are demonstrated for dual encryption, combining visual and sound information, as well as multiplex 2D barcodes that integrate multiple domains into a single quick response code.
