Abstract
A light-emitting audio device, an audio output device, and a display device. The light-emitting audio device includes a micro device integrated with a micro LED device and piezoelectric device. Both image display and audio output can be enabled using a single device. Audio is output using a plurality of light-emitting audio devices disposed in a plurality of subpixels, respectively. An increase in the thickness of the display device due to integrate with a audio function can be minimized. A variety of audio output functions are provided by driving the light-emitting audio devices according to areas.
