ABSTRACT:
A liquid-crystal display according to this invention which incorporates timing signal generation circuit 13 which turns on switches 10 to 12 when interval control signal P from the liquid-crystal power supply circuit is in active status, and which turns switches 10 to 12 off when interval control signal P is in inactive status. By turning switches 10 to 12 off when no display is required, current flow from power supply 3 to ground (GND) is cut and power consumption is reduced.
