Abstract
It is an object of the present invention to provide a control circuit for charging and discharging () etc., which can prevent an undesirable-emission caused by a residual charge, capable of obtaining a high-quality display and so on. The control circuit for charging and discharging () includes a driven element (E-E) with a driving-on status and a driving-off status; a charging element, whose one end is grounded; and a driving circuit (), which is connected to the driven element (E-E), for controlling the driving-on status or the driving-off status in the driven element. The control circuit further includes a charging path, which is connected to the driven element (E-E), for charging the charging element with a residual charge, which is produced in the driven element (E-E) and/or a line connected to the driven element (E-E) during the driving-on status, and a discharging path, which is connected to the charging path, for discharging the residual charge from the charging element to a ground in the driving-on status.
