Abstract

See full text

A display control device controls a display device provided with a group of scanning electrodes and a group of signal electrodes and a display element placed therebetween. A driver circuit applies a non-zero first scanning signal to a selected one of the group of scanning electrodes during a first period and applies a non-zero second scanning signal to the selected scanning electrode in a second period after the first period. The first and second scanning signals are applied to the selected scanning electrode when a driving signal is applied to a predetermined number of signal electrodes of the group of signal electrodes. The first and second periods are separated by a rest period, and a polarity of a portion of the first scanning signal immediately before the rest period is opposite to a polarity of a portion of the second scanning signal immediately after the rest period.
