Filed: 1996-11-18
Abstract: PROBLEM TO BE SOLVED: To reduce loss in a recovery circuit at a low cost by providing a write power supply switch between the power supply terminal of a driver for write and a power supply for the write and turning the switch to an OFF state during a maintenance discharge period. SOLUTION: The write power supply switch 25 provided between the driver 13 for the write and the power supply 6 for the write is turned to the OFF state during the period of impressing rectangular AC to an X electrode group and a Y electrode group by an inverter switch 8 and the recovery circuit. Since the output Wout of the driver 13 for the write is turned to a floating state, a potential is decided by the divided voltage of the size of W-X capacitance 16 and W-Y capacitance 17. A displacement current made to flow to the W-X capacitance 16 and the W-Y capacitance 17 is not passed through the resistor group of the driver 13 for the write since the write power supply switch 25 is non-conductive. Thus, the loss of the driver 13 for the write is not generated during the maintenance discharge period.
