ABSTRACT:
A driving circuit for display elements, comprises a modulation circuit that outputs a modulating signal to be applied to wiring to which display elements are connected; and an output circuit that serializes modulation data including height value data for determining a height value of at least part of waveform of the modulating signal and pulse width data for determining a pulse width of at least part of waveform of the modulating signal so that the modulation data can be transmitted to the modulation circuit by transmission paths, the number of which is smaller than the number of bits of the modulation data, and outputs the serialized modulation data.
