    • The present invention relates to a plasma display apparatus including a sustain driving apparatus that supplies a sustain signal to a panel. The plasma display apparatus includes a panel in which a front substrate having formed first and second electrodes therein and a rear substrate are coalesced, a sustain driver including a first switch for applying a first voltage to any one of the first and second electrodes and a second switch for applying a second voltage, and a circuit protection unit that controls one of the first and second switches, which has a voltage higher than a predetermined voltage, at its both ends, not to turn on. According to the present invention, when a voltage at both ends of the switch included in the sustain driving apparatus in order to supply the sustain signal is higher than a reference voltage, the switch is controlled not to turn on. It is therefore possible to prevent damage due to the short of the sustain driving apparatus and, therefore, to improve the lifespan and reliability of a product.
    • 等离子体显示装置技术领域本发明涉及一种包括向面板提供维持信号的维持驱动装置的等离子体显示装置。 等离子体显示装置包括面板,其中已经形成有第一和第二电极的前基板和后基板被聚结,维持驱动器包括用于向第一和第二电极中的任何一个施加第一电压的第一开关和第二电极 用于施加第二电压的开关,以及电路保护单元,其在两端控制具有高于预定电压的电压的第一和第二开关之一,而不是导通。 根据本发明,为了提供维持信号,包含在维持驱动装置中的开关的两端的电压高于参考电压时,控制开关不导通。 因此,可以防止由于维持驱动装置的短路造成的损坏,并且因此可以提高产品的寿命和可靠性。
