Abstract

A driver includes a pixel drive circuit configured to drive a pixel of an electro-optical panel by an output voltage corresponding to gradation data via an output terminal TQj, a pre-charge switch SWP having one end electrically coupled to the output terminal TQj, a plurality of pre-charge capacitors CP1 to CP8, each having one end electrically coupled to the other end of the pre-charge switch SWP, a pre-charge capacitor drive circuit configured to drive the other end of each of the pre-charge capacitors based on pre-charge data, and a control circuit configured to output the pre-charge data to the pre-charge capacitor drive circuit. During a pre-charge period, the control circuit turns on the pre-charge switch SWP, and sets the pre-charge data to predetermined data in which the signal supply line becomes a pre-charge voltage.
