  • Patent number: 8203549
    Abstract: A plasma display panel driving method and a plasma display apparatus are disclosed in which a suitable address discharge can be performed at a next scanning timing by reducing voltage changes in a sustain electrode and a scan electrode caused by a change of an address pulse when the address pulse is applied to an address electrode at a scanning timing. The plasma display panel driving method drives a plasma display panel which includes plural scan electrodes extending in a first direction and plural address electrodes extending in a second direction orthogonal to the first direction. In the method, a negative polarity scan pulse is applied to a scan electrode, a positive polarity address pulse is applied to an address electrode from an address electrode driving circuit, and an address discharge is generated.

  • Publication number: 20080024395
    Abstract: A plasma display apparatus includes a display panel including first electrodes, second electrodes, and third electrodes, a first drive circuit configured to drive the first electrodes, a plurality of scan circuits configured to successively scan the first electrodes, a second drive circuit configured to drive the second electrodes, a third drive circuit configured to drive the third electrodes while the plurality of scan circuits successively scan the first electrodes to supply a drive power from the first drive circuit to the first electrodes, and a delay unit inserted into an interconnect connecting between at least one of the plurality of scan circuits and the first drive circuit, wherein electric currents supplied from the first drive circuit flow at different timings into at least two of the plurality of scan circuits in response to a propagation delay on the interconnect caused by the delay unit.
