Abstract
A liquid discharge apparatus includes a discharge section, a charge supply source, first and second signal paths, a control signal generation section and a connection path selection section. The discharge section includes a nozzle configured and arranged to discharge a liquid, a pressure chamber in communication with the nozzle, and a piezoelectric element provided for the pressure chamber. A first voltage is applied by the charge supply source through the first signal path. A second voltage higher than the first voltage is applied by the charge supply source through the second signal path. The control signal generation section is configured to supply a control signal. The connection path selection section is configured to use the first or second signal path to electrically connect the piezoelectric element and the charge supply source in accordance with a voltage of the control signal and a holding voltage of the piezoelectric element.
