Abstract

A display panel device includes a display panel having a sensor sensitive to light, sound, heat and so on and a recorder/playback combination attached thereto. As an object transparent to or shielding light and generating sound or heat approaches the panel, the sensor is automatically actuated to give an automatic actuation to the recorder/playback combination, thereby reproducing music or sound from the surface of the display panel.
