Abstract
PURPOSE: To simplify the drive circuit, by operating the shift register with the circuit generating the number of pulses depending on the input amount and the count circuit, and by generating the signal to select the voltage fed to the block and segment electrode.
CONSTITUTION: The display unit is constituted with the block electrode split in m sets, segment electrode having n sets of segments to each block by opposing to the electrode, pulse generation circuit 21 outputting the number of pulses depending on the input amount to be displayed, count circuit 22 outputting the pulse signal depending on the value dividing the output of the circuit 21 with the number of segments, segment electrode drive circuit 25 driven with the voltage fed to each electrode at the segment side depending on the output of the circuits 21 and 22, shift register 23 selecting the state of electrode at block side depending on the output of the circuit 22, and the drive circuit having the multiplexer 24 applying voltage to the block side electrode depending on the content of the reigster 23.
