  • Publication number: 20080238329
    Abstract: A plasma display device and driving method thereof are disclosed. In the plasma display device, a wall charge state of each cell is initialized after forming a wall voltage between respective sustain electrodes by gradually decreasing a voltage of the sustain electrodes. In addition, in a sustain period, a high level sustain discharge pulse having a positive voltage and a low level sustain discharge pulse having a negative voltage are applied to the sustain electrode while maintaining a voltage of a scan electrode at a ground voltage. In this way, a maximum voltage applied to a scan electrode driver that applies the driving waveform to the scan electrode is decreased. In addition, a sustain discharge pulse is applied only to the sustain electrode, which is a common electrode, and therefore the driving waveform between each cell can be prevented from being distorted in the sustain period.

  • Publication number: 20080174520
    Abstract: A plasma display device and a driving method thereof. The plasma display device includes drivers for scan, sustain and address electrodes and a controller for controlling the drivers. The scan electrode driver includes a capacitor whose charge is proportional to an on period of a switch included in the driver circuit or may be otherwise controlled. By controlling the charge of the capacitor, a voltage difference between the reset falling voltage and the select voltage that are applied to the scan electrodes during the reset and subsequent address periods can be controlled to control the discharge margin and to correspond to the design of the plasma display device. The need for a Zener diode with a high withstand voltage is alleviated.

  • Publication number: 20080143641
    Abstract: A plasma display device and a driving method thereof. During a sustain period of a first subfield, a sustain discharge alternating waveform alternating between a Vs voltage and a ?Vs voltage is applied to a sustain electrode while a scan electrode is supplied with a constant reference voltage. During an initialization period of a second subfield consecutive to the first subfield, a voltage of the sustain electrode is gradually decreased from a ground voltage to a negative voltage while a scan electrode is applied with the ground voltage, causing a weak discharge to be generated between the scan electrode and the sustain electrode and between the sustain electrode and an address electrode so that wall charges formed on each electrode are partially erased. Accordingly, a scan electrode driver does not need a power recovery circuit by applying the sustain discharge pulse only to the sustain electrode. In addition, an appropriate wall charge distribution can be achieved thus eliminating misfiring.
