Abstract
In the case where a ticking timing of a clock unit changes, a CPU of an electronic timepiece outputs a synchronization request signal to a CPU of a display module at the next ticking timing after the change so as to request resynchronization. Each time a timer circuit counts a prescribed number of pulses in a clock signal generated by a clock generation circuit on the basis of the ticking timing, the CPU of the display module instructs a liquid crystal driver circuit to invert the polarity of an AC voltage to be applied to a liquid crystal panel. Moreover, upon receiving the synchronization request signal from the CPU of the electronic timepiece, the CPU of the display module sets the timer circuit to start a new count of the clock.
