Abstract:
A driver device for a capacitive light emitting element includes a semiconductor integrated device and an electrical charge recovery circuit. The semiconductor integrated device includes a plurality of output buffers that supply a drive data-dependent voltage to each of a plurality of capacitive light emitting elements. The semiconductor integrated device also includes a plurality of switching elements that supply a high voltage to each of the output buffers. An external terminal of the semiconductor integrated device is commonly connected to respective nodes between the switching elements and output buffers. The electrical charge recovery circuit recovers electrical charge that has accumulated in the capacitive light emitting elements. The electrical charge recovery circuit is connected to the external terminal of the semiconductor integrated device.
