摘要：
A driver circuit is configured to drive light-emitting elements. The driver circuit includes a light-emitting element, a power switching element, a control circuit, and a charge pump circuit. The power switching element includes a first terminal connected to the light-emitting element and turns on and off the light-emitting element. The control circuit is connected to a second terminal of the power switching element and controls a switching operation of the power switching element. The charge pump circuit is connected between the control circuit and a power source for the light-emitting element and supplies current to the control circuit for driving the control circuit.
