Abstract
A driver includes a data voltage output terminal electrically coupled to a data line through a data line switch of an electro-optical panel, a capacitor driving circuit configured to output first to nth capacitor driving voltages corresponding to gradation data to first to nth capacitor driving nodes, a capacitor circuit including first to nth capacitors provided between an output node and the first to nth capacitor driving nodes, a processing circuit configured to calculate an excess/deficient charge amount of the output node when the data line switch is turned on, and a charge compensation circuit configured to inject into the output node or discharge from the output node a compensation charge based on the excess/deficient charge amount calculated by the processing circuit, by using a charge compensation capacitor circuit.
