Abstract

PURPOSE: To simplify a driving circuit by connecting display elements as many as N in series and then by connecting the outputs of switching elements to respective connection points and one terminal of the 1st display element.
CONSTITUTION: The display unit consists of peak holding circuit 14 which holds the peak value of input signal 13, the N-number comparators 151W15N supplied with the output of peak holding circuit 14, the N-number switching elements 271W27n supplied with the outputs of those comparators as control inputs and controlling the transmission of the output of driving power source 26, and the N-number display elements EL1WELN providing optical display effect by being applied with a voltage to opposite electrodes. Between output terminals of switching elements 271 and 272, those of elements 272 and 273 and those of elements 27N-1 and 27N, display elements EL1WELN-1 are sequentially connected and between the output terminal of switching element 27N and the earth line, display element ELN is connected to constitute the driving circuit.
