A sound and vision system includes a display device (1) and an acoustic transducer, such as a loudspeaker or a microphone. The display device includes display cells (9) having opposite electrodes (7, 8) and includes a conductive line (11) connected to the electrodes in order to address the display cells. The acoustic transducer is formed by the display cell itself and the conductive line is electrically coupled to the display cell/acoustic transducer in order to convey signals, as a result of which the acoustic transducer is an integral part of the display device.
