Abstract

PURPOSE: To readily obtain signals of changing and renewing of displaying by EC display body by making use of the signals at the rise and fall of the segments of a part of number display segments in an electronic watch or the like.
CONSTITUTION: In the case of subsequently and repeatedly displaying numbers from 0 to 9, the output 8 of the (e) segment 5 and the output 9 of the (a) segment 1 out of the decoder outputs of an ordinary LSI corresponding to the 7 segments (a) thru (g) of number display are applied respectively to the pulse generators 10, 11 of a driver. At the rise and fall of these inputs, pulses 12, 13 are respectively produced and periodic clock pulses 15 are obtained by an OR circuit 14. In this case, the same holds true even when the (a) segment is replaced with (d) segment. Hence, the clock pulses coincided to the decoder outputs may be obtained simply by connecting the driver and driving of the EC display body mey be made easy.
