Abstract

Disclosed is a data display circuit which comprises a shift register circuit including six cascade-connected shift registers shifting serial data to produce parallel data, a decoder circuit including three decoders receiving the parallel data from the shift register circuit and producing output data corresponding to such input data, a latch circuit coupled to the decoder circuit, a control circuit coupled to the decoder circuit and the latch circuit and supplying these decoder and latch circuits with control pulses so that output data from the decoder circuit may be held temporarily in the latch circuit, and a display device for displaying output data from the latch circuit. In this data display circuit, the three decoders have input terminals coupled respectively with the output terminals of different groups of four cascade-connected shift registers of the shift register circuit, and the control circuit energizes the three decoders at different times, thereby applying substantially the same data from the shift registers to the decoders.
