Abstract An optical character-displaying apparatus having a plurality of segmental liquid crystal electrodes acting as display elements so arranged as to present any desired character, wherein the plural segmental liquid crystal electrodes acting as display elements are connected to the corresponding bit sections of a memory device which are provided in the same number as the segmental liquid crystal electrodes. Numerical data being indicated on the display apparatus is previously stored in an entry register and then conducted therefrom through a logic circuit to the memory device. The memory device is subjected to shifting by clock pulses delivered by a timing pulse generator for each word time, thereby producing output signals from the bit sections corresponding to the stored numerical data for final presentation on the subject character-displaying apparatus. A potential is alternately impressed across a common electrode and the plural segmental liquid crystal electrodes acting as display elements by cooperation between an output signal delivered in a state inverted per determinate word by a flip-flop circuit connected to the common electrode and the inversion of signal polarity effected by an inverter connected between the input and output terminals of the memory device.
An optical character-displaying apparatus using liquid crystals which comprises Liquid crystal display devices each including a plurality of segmental liquid crystal display electrodes and a common electrode thereto; a memory device having as many bits as the segmental liquid crystal display electrodes of the display devices; an inverter connected between the input and output terminals of the memory device so as to invert the polarity of signals supplied to said inverter; a shift controlling device for supplying shift pulses to the memory device for the prescribed period in which the signals stored in the memory device have their polarity inverted by the inverter and then are shifted through the memory device; and switching signal generating means for changing the potential of the common electrode according to the inverted potential of the plural segmental liquid crystal display electrodes in synchronization with the shift pulse generated by the shift controlling device.
