ABSTRACT:
An image display apparatus includes row wiring, a plurality of column wirings, a modulator, and a plurality of display devices. The plurality of display devices are commonly connected to the row wiring, each of the plurality of column wirings is connected to a corresponding one of the plurality of display devices, and the modulator supplies a modulated signal to the column wirings. The modulator includes a pulse width modulator for generating a pulse signal having a time width corresponding to the tone of a signal to be displayed, and a potential setting circuit for setting the potential of the pulse signal in accordance with the type of signal to be displayed.
