1. A display device comprising a display panel, wherein the display device further includes:
a plurality of exciters arranged on the display panel, the display panel producing sound on a screen through the plurality of exciters;
wherein, the plurality of the exciters are formed as at least one sound producing unit, each sound producing unit includes at least two exciters, and each exciter in the same sound producing unit is connected to a same audio signal input end, in one sound producing unit, a signal filter is provided on an audio transmission line from the audio signal input end to each exciter, and used for low frequency compensation of a sound produced by the entire sound producing unit,
wherein, the signal filter comprises a low-pass filter and a high-pass filter, in the same sound producing unit, the low-pass filter and the high-pass filter are provided on the audio transmission line from the audio signal input end to each exciter of the at least two exciters, and an audio signal at the audio signal input end passes through the low-pass filter to obtain a low frequency signal, passes through the high-pass filter to obtain a high frequency signal, and the low frequency signal and the high frequency signal are superimposed, normalized and then transmitted to each exciter of the at least two exciters, the each exciter of the at least two exciters vibrates and produces sound.
