摘要

When switch is off (1), first charger (C1) charges parasitic capacitance (CS). Then (1), switch (SW) is kept off and second charger (C2) charges internal capacitance (CD). Switch is turned on (3) and charge in internal capacitance flows into parasitic capacitance (CS), and voltage across internal capacitance becomes equal to voltage across parasitic capacitance. Switch is turned off again (4), and the second charger charges internal capacitance. Independent claims are included for D/A converter, signal driver, electro-optical panel, projection display, and electronic device.
