Abstract
A drive device of a display panel includes a controller that controls operations of a scanning-control signal output circuit and a common-electrode voltage control circuit, wherein when the controller receives a changeover command that indicates changeover of a scanning order of a plurality of scanning signal lines, the controller controls an operation of the scanning-control signal output circuit so that a scanning order of the plurality of scanning signal lines is changed over between a normal order and a reverse order and controls an operation of the common-electrode voltage control circuit so that a voltage of the common electrode is changed over between a voltage determined in advance for normal-order scan and a voltage determined in advance for reverse-order scan, during a scanning order changeover period as a predetermined period after ending last scanning of a scanning signal line during a frame period in which the changeover command is received.
