Abstract
PURPOSE: To reduce comsumption power with reducing the loss current at a zero mask time by using a pulse, which has a pulse width narrower than a normal digit pulse, as a displaying digit pulse for the zero-masked digit in a display circuit.
CONSTITUTION: In the display circuit in the digital control equipment which drives a fluorescent display tube in the dynamic driving system, word wime counter 1 where word clock ϕW is inputted is provided, and the output of counter 1 is inputted to ROM to form circulating displaying digit signals W1→W2...W13→W1. Menswhile, digital clock ϕD is inputted to digital time counter 2, and the output of counter 2 is inputted to ROM to form timing signal A. Then, signal A is used as a timing signal which distributes contents of shift register 3 storing displayed data to each digit synchronously with displaying digit signals W1 to W13 and writes them into shift register 4.
