Abstract
PURPOSE: To perform displaying of high accuracy with circuits of less number of driving circuits and simple constitution by driving required number of segment electrodes according to the combinatins of the signal information being applied to common electrodes and segment electrodes thereby making liquid crystal displaying.
CONSTITUTION: Analog measurement input data are converted to binary information and decimal numbers by an A/D converter 8, decoders 9, 9', then the outputs of the output ends of the decoder 9 corresponding to the number of the 10th place of the input data and the output ends of the decoder 9' corresponding to the number of the 1st place of the input data invert, opening the corresponding OR gates 10..., 10'... Then driving voltages are applied to the reguired electrodes out of the common electrodes 5... corresponding to 10 pieces of the segment electrodes 4... opposing on both sides of liquid crystal 6 and required number of electrodes 4..., whereby bar graph displaying by the liquid crystal 6 according to the input data is accomplished with high accuracy. Hence, the segment electrodes are eollectively driven for each of the segment groups and the number of driving circuits is less then that of the cases when driving circuits are provided for each of the segment electrodes, thus highly accurately displaying is performed with the simple constitution.
