Abstract:
A drive circuit and a drive current correcting method are described herein. The drive circuit comprises a current source that outputs a drive current, and a correction circuit that outputs a correction current. The correction circuit includes a first RC time constant circuit. An output terminal of the current source is connected to an output terminal of the correction circuit.
