  • Patent number: 7733304
    Abstract: A plasma display includes a plurality of scan electrodes. A scan voltage is sequentially supplied to the plurality of scan electrodes, and a non-scan voltage that is higher than the scan voltage is supplied to scan electrodes to which the scan voltage is supplied. The non-scan voltage is generated by dividing a voltage that is higher than the non-scan voltage and the scan voltage. Thus, a voltage source for supplying the non-scan voltage can be eliminated.

  • Publication number: 20090115697
    Abstract: In a plasma display device and a driving method thereof, a scan voltage is set to be lower than a reset minimum voltage in order to reduce an address discharge delay in an address period. In addition, in the address period, an address voltage and a scan voltage are set to be lower. In order to prevent misfiring in the address period, a voltage biasing a sustain electrode in the address period is set to be lower than a voltage biasing the sustain electrode in a falling period of a reset period.

  • Publication number: 20070085848
    Abstract: A plasma display device and a power supply thereof having a fewer number of power sources in the plasma display device is disclosed. The power supply generates a voltage corresponding to a Ve power source by using a variable resistance through a voltage distribution principle without including a Ve power source. In addition, since a power supply circuit including a thermistor is used in order to correspond to a discharge firing voltage which is changed by a temperature, a sustain discharge is stably generated by adjusting a Ve voltage without including a Ve power source.

  • Publication number: 20060273989
    Abstract: A plasma display device and a driving method thereof. A sustain discharge before a reset period for initializing a cell which is sustain discharged in a previous subfield is generated as a weak discharge rather than a strong discharge. By generating a weak sustain discharge, the amount of wall charge formed in the exterior area of electrodes may be reduced. As a result, in the subsequent reset period, the wall charge can be controlled to be appropriate for addressing while preventing misfiring and low discharge.
