Abstract
Current-driven display elements are disposed in the form of a matrix at each of intersections of a plurality of scanning electrodes ScE (ScE1, ScE2, . . . , ScEy) and a plurality of signal electrodes SiE (SiE1, SiE2, . . . , SiEx), a scanning electrode ScE is selected and a display signal is supplied to the signal electrode SiE, to drive each current-driven display element. Means for precharging an electric charge for a capacity of the intersections before supplying the display signal to the signal electrodes SiE, thereby suppressing the influence of a stray capacitance developed at the intersections of the scanning and signal electrodes.
