摘要： An electrode drive circuit of a plasma display device includes a scan driver provided with plural drivers having first and second switching elements and first and second diodes, and a positive reset pulse generating circuit by which a first superposed voltage obtained by applying a predetermined first voltage to a low potential side terminal of the second switching element and superposing the first voltage and a voltage between a high potential side terminal of the first switching element and the low potential side terminal of the second switching element is generated to the high potential side terminal of the first switching element. The first superposed voltage is applied to the electrodes via the first switching element.

摘要： A flat display employs at least one high voltage different from logic voltages. The display has a voltage detection unit and a drive control signal control unit. The voltage detection unit is used to detect the high voltage. The drive control signal control unit is used to control drive control signals of the flat display in accordance with the detected high voltage. This arrangement eliminates charging currents that are applied to a display panel but have nothing to do on the actual displaying of data, or reactive currents due to unnecessary switching operations, thereby reducing power consumption.
