    • In one embodiment, a plasma display device includes: a plasma display panel having a plurality of electrodes; a power supply including first and second power sources for respectively supplying first and second voltages, the second voltage being higher than the first voltage; a driving circuit for driving the electrodes; and a controller for generating a first signal to control the driving circuit. The driving circuit includes: a first switch for supplying a third voltage to the electrodes, the third voltage decreasing over a period of time; a switching controller for controlling the first switch in accordance with the first signal and a second signal; and a feedback signal generator for comparing fourth and fifth voltages respectively proportional to the third and second voltages, adjusting a level of the second signal according to a result of comparing the fourth and fifth voltages, and supplying the second signal to the switching controller.
    • 在一个实施例中,等离子体显示装置包括:具有多个电极的等离子体显示面板; 电源,包括用于分别提供第一和第二电压的第一和第二电源,第二电压高于第一电压; 用于驱动电极的驱动电路; 以及用于产生用于控制驱动电路的第一信号的控制器。 驱动电路包括:第一开关,用于向电极提供第三电压,第三电压在一段时间内减小; 开关控制器,用于根据第一信号和第二信号控制第一开关; 以及反馈信号发生器,用于比较分别与第三和第二电压成比例的第四和第五电压,根据比较第四和第五电压的结果调整第二信号的电平,并将第二信号提供给开关控制器。
