    • In plasma display device, a transistor includes a source terminal connected to a power supply that sequentially applies voltage pulses having a scan voltage to a plurality of scan electrode in a address period, and a drain terminal connected to a plurality of scan electrodes. A first resistor is connected between the source and the gate terminals of the transistor, and a second resistor is connected between the drain and the gate terminals of the transistor. A Zener diode is connected to the first resistor between the source and the gate terminals of the transistor. Therefore, a voltage finally applied to the plurality of scan electrodes can be generated using the same power supply that supplies the scan voltage in the falling period of the reset period.
    • 在等离子体显示装置中,晶体管包括连接到电源的源极端子,其在寻址周期中顺序地向多个扫描电极施加具有扫描电压的电压脉冲,以及连接到多个扫描电极的漏极端子。 第一电阻器连接在晶体管的源极和栅极端子之间,并且第二电阻器连接在晶体管的漏极和栅极端子之间。 齐纳二极管连接到晶体管的源极和栅极端子之间的第一个电阻。 因此,可以使用在复位期间的下降期间提供扫描电压的相同电源来产生最终施加到多个扫描电极的电压。

    • Reset, address, and sustain operations of a plasma display device are performed by applying a driving waveform to a scan electrode while biasing a sustain electrode at a ground voltage allowing a driving board for driving the sustain board to be eliminated. Since a low voltage is applied to the scan electrode while biasing the sustain electrode at the ground voltage during the reset period, a potential formed by a wall charge may be greater at the scan electrode than at the address electrode. In addition, a misfiring discharge may be prevented during the sustain period when a low voltage applied to the scan electrode during the sustain period is set to be greater than the scan voltage of a scan pulse applied to the scan electrode during the address period.
    • 通过向扫描电极施加驱动波形,同时使维持电极以能够驱动维持板的驱动板被消除的接地电压偏压来执行等离子体显示装置的复位,地址和维持操作。 由于在复位期间将维持电极施加在接地电压的同时向扫描电极施加低电压,所以在扫描电极处形成的壁电荷所形成的电位比寻址电极处的电位大。 此外,在维持期间施加到扫描电极的低电压被设定为大于在写入期间施加于扫描电极的扫描脉冲的扫描电压的维持期间,可以防止发生点火放电。
