    • The present invention relates to a liquid crystal cell having a plural number of electrode pairs arranged on both sides of the liquid crystal matter so as to be opposed to each other, being characterized in that a pulse wave generating device for generating the first pulse wave with smaller amplitude than the threshold valve for lighting the liquid crystal and the second pulse wave with larger amplitude than the threshold value for lighting the liquid crystal in reversed phase to each other and a gate device for selectively applying the outputs of the pulse wave generating device to each electrode of the liquid crystal cell in accordance with the input signal are provided. Thus only the voltage between the selecting electrodes is highter than the threshold value. An input change over device is provided so as to change over the input signal group in a time dividing way in such a manner that a plural number of dots can be displayed visually at the same time, as a result, the wiring is simplified.
    • 本发明涉及一种具有多个电极对的液晶单元,液晶单元布置在液晶物质的两侧以彼此相对,其特征在于:脉波产生装置,用于产生具有 比用于点亮液晶的阈值阀的振幅小,并且具有比阈值大的振幅的第二脉冲波,用于将液晶彼此反相点亮;以及门装置,用于选择性地将脉波发生装置的输出施加到 提供根据输入信号的液晶单元的每个电极。 因此,只有选择电极之间的电压高于阈值。 提供了一种输入切换装置,以便以时间分割的方式改变输入信号组,使得可以同时可视地显示多个点,结果简化了布线。
