  • Patent number: 11067916
    Abstract: A driving apparatus comprising a driving circuit is provided. The driving circuit includes an output terminal to which the load element is connected, a current output circuit configured to supply a current to the load element, a voltage supply circuit configured to apply a voltage to the load element, a first signal line configured to control a timing at which the current output circuit starts supplying a current to the load element and a second signal line configured to control a timing at which the voltage supply circuit is turned off. The voltage supply circuit starts applying a voltage before the current output circuit supplies a current to the load element, and a timing at which the current output circuit starts supplying a current differs from a timing at which the voltage supply circuit turns off application of a voltage.
