    • A digital display type electronic time keeper is disclosed which has a time standard signal generating source having a crystal oscillating circuit. Means are provided for frequency-dividing the time standard signal, for counting the signal fed from the means for frequency-dividing the time standard signal which is driven by at least one power source, and for decoding the counted data. A display device having a positive dielectric anisotropy twisted effect type nematic liquid crystal is driven by the decoded signal. A booster using two phase signals taken from a part of the frequency dividing means provides a power source for driving the counting means, the decoding means and the display device. A level adjuster matches the output of the frequency-dividing means and the input of the counting means and is disposed therebetween. Additional means are provided for correcting the display data of the display device.
    • 公开了一种具有晶体振荡电路的时间标准信号发生源的数字显示型电子计时器。 提供了用于对时间标准信号进行分频的装置,用于对由用于对由至少一个电源驱动的时间标准信号进行分频的装置馈送的信号进行计数和对计数数据进行解码的装置。 具有正介电各向异性扭转效应型向列型液晶的显示装置由解码信号驱动。 使用从分频装置的一部分获取的两相信号的增强器提供用于驱动计数装置,解码装置和显示装置的电源。 电平调节器与分频装置的输出和计数装置的输入相匹配并且设置在它们之间。 提供了用于校正显示装置的显示数据的附加装置。
