Abstract:
1. A driving circuit comprising: a first amplifier circuit for charging and driving an output terminal of said driving circuit; a second amplifier circuit for discharging and driving said output terminal; said first and second amplifier circuits having respectively first and second operating voltage ranges overlapping at least in part each other; and an input control circuit receiving a first voltage located at a lower limit side of an overlapped portion between the first operating voltage range and the second operating voltage range, a second voltage located at an upper limit side of the overlapped portion, and a target voltage, for selecting at least one of the received voltages to supply the selected voltage to at least one of an input terminal of said first amplifier circuit and an input terminal of said second amplifier circuit; wherein a driving period for driving said output terminal to the target voltage being made up by at least a first period and a second period; said input control circuit performing control so that during the first period, one of the first voltage and the second voltage, is supplied in common to said input terminals of said first amplifier circuit and said second amplifier circuit, or the first and second voltages are respectively supplied to said input terminal of said first amplifier circuit and said input terminal of said second amplifier circuit, and during the second period, the target voltage is supplied in common to said input terminals of said first amplifier circuit and said second amplifier circuit.
