Display prototype moves sound across the screen with video objects

Researchers at the Korea Institute of Machinery and Materials demonstrated a display prototype that moves sound-emitting areas across its surface to follow objects in video. Tests reported 99.9% accuracy in selecting intended sound zones, while an acoustic camera confirmed that the sound location could track moving objects. The approximately 100-inch prototype uses 80 electromagnetic motors behind an aluminum panel covered with transparent LED film. Coordinated voltage signals concentrate vibrations in selected areas; AI separates audio sources and locates corresponding objects in the video. The research demonstrated effective vibration localization below 500 Hz. Its modular design allows display sections to be combined or separated for different screen sizes.
