Pixel-Based Local Sound OLED: The Screen Becomes the Speaker

A POSTECH research team has unveiled the world's first Pixel-Based Local Sound OLED technology, enabling each pixel to emit distinct sounds, effectively turning the display into a multi-channel speaker array. Successfully demonstrated on a 13-inch OLED panel, this breakthrough eliminates the need for external speakers, offering immersive audio directly from the screen. Published in Advanced Science, this technology addresses the limitations of traditional displays by enabling truly localized sound experiences. Imagine a car where the driver hears navigation while the passenger enjoys music, all from the same screen. This innovation promises a revolution in mobile, automotive, and VR displays.
