Abstract
A display device includes independently driven common and segment terminals. The common and segment terminals are connected to display components divided into display blocks that are turned ON to perform a display function and are turned OFF so as to not perform the display function. A first driver drives the common terminals using a scanning signal of a predetermined period and a second driver drives the segment terminals using a segment signal synchronized with the scanning signal to correspond to a display signal, so that the display components perform a display corresponding to the display signal. The first driver separates the common terminals into common terminal blocks and drives the common terminals. The first and second drivers perform the driving so that the common and segment terminals which are connected to display blocks that are turned OFF are not supplied with a turn-off signal and are maintained at ground potential.
