Abstract
A flat display employs a high voltage different from logic voltages and has a voltage detection unit and a drive control signal control unit. The voltage detection unit detects the high voltage and the drive control signal control unit controls drive control signals of the flat display in accordance with the detected high voltage. This arrangement eliminates charging currents which normally are applied to a display panel but are unrelated to the actual displaying of data and also reactive currents caused by unnecessary switching operations, thereby reducing power consumption.
