Abstract

A digital electronic timepiece having a multi-digit digital display for displaying the time count in a time counter which receives a divided down time signal from a time base signal generator. At least one settable time counter for storing a count corresponding to a desired time period is provided which is receptive of a time signal for decrementing the count thereof to zero. A plurality of display driving signals, each corresponding to one digit of display are generated wherein the display signals of successive digits are phase delayed with respect to each other and the frequency thereof is sufficiently low to produce visible flickering of display. Upon the sensing of the zero count in the timer counter, the display which is normally non-flickering, is driven with the display driving signals to produce a sequential flickering of the digits of the time display to provide a visual indication of the lapse of the desired time period.
