Abstract
A driver circuit for driving a capacitive load has a first electrode and a second electrode. The driver circuit includes: a first charging section, connected with the first electrode, for applying a charge to the first electrode during a. first period and receiving a charge from the first electrode during a second period; a second charging section, connected with the second electrode, for receiving a charge from the second electrode during the first period and applying a charge to the second electrode during the second period; a first section for prohibiting a movement of a charge between the first charging section and the first electrode during a third period between the first period and the second period; a second section for prohibiting a movement of a charge between the second charging section and the second electrode during the third period; and a third section for allowing a movement of a charge between the first electrode and the second electrode during a fourth period included in the third period.
