Abstract:
A driver includes a data voltage output terminal, a capacitor drive circuit that outputs each of first to n-th capacitor drive voltages corresponding to gradation data to a respective one of first to n-th capacitor driving nodes, a capacitor circuit including first to n-th capacitors each provided between an output node and a respective one of the first to n-th capacitor driving nodes, a processing circuit that generates a correction signal for correcting a voltage difference between an output voltage and a target voltage corresponding to the gradation data, and a correction circuit that corrects the voltage difference with a correction voltage corresponding to the voltage difference by injecting a charge corresponding to the correction signal into the output node or discharging the charge from the output node by using the correction capacitor circuit.
