    • A driving circuit for alternately referencing display electrodes to a predetermined potential difference with respect to each other in order to effect AC driving thereof is provided. A first drive circuit is coupled to a common electrode of each display cell for alternately referencing the common electrode between first and second opposite potentials for a predetermined interval of time. A second drive circuit is coupled to a segment electrode defining each display cell for selectively referencing the segment electrode to a potential opposite in polarity to the potential of the common electrode to define a predetermined potential difference between the common electrode and segment electrode to thereby render the display cell visually distinguishable for less than the predetermined interval of time. The second drive circuit is further adapted to reference the segment electrode to the same polarity potential as the common electrode during the remaining portion of the predetermined interval of time to thereby permit the display cell to be discharged during the remaining portion of the predetermined interval of time, and hence reduce the current required to effect AC driving of the display cell.

    • A timepiece includes in addition to the conventional timekeeping circuits, high load, that is, high current circuits such as an alarm driving circuit and a lamp driving circuit. Low load, small current systems such as the oscillator, divider, display drivers and display for timekeeping are operated directly from the battery voltage source when the high load circuits are off. When the high load circuits are on, the low load circuits are disconnected from the battery and operate from an electric charge stored in a capacitor connected in parallel with the low load circuits. The high load circuits are driven intermittently at a high frequency to reduce power consumption and to permit recharging of the storage capacitor during off-periods. The drive frequency is sufficiently high such that an illumination lamp shows no flicker and brightness is controlled by duty cycle.

Mode select circuitry that is coordinately disposable between a timekeeping mode and a correction mode is disposed intermediate a manually actuatable control circuit and the timekeeping circuitry and digital display. When the mode select circuitry is disposed in a timekeeping mode, actuation of the control circuitry will result in the digital display changing from a display of the first type of time information to a display of the second type of time information produced by the timekeeping circuitry. However, when the mode select circuitry is in a correction mode, the mode select circuitry will select the particular timekeeping circuitry to be corrected, and if the timekeeping circuitry to be corrected is producing the second type of time information, the mode select circuitry will change over the digital display from the display of the first type of time information to the second type of time information.
