  • Patent number: 8044886
    Abstract: The present invention relates to a plasma display apparatus and, more particularly, to a method of driving a plasma display panel. The plasma display apparatus includes a plasma display panel including a plurality of scan electrodes and sustain electrodes formed on an upper substrate, and a plurality of address electrodes formed on a lower substrate, and a driver for supplying driving signals to the plurality of electrodes. The plurality of scan electrodes are divided into first and second groups and then supplied with scan signals, and scan bias voltages supplied to the first and second groups in at least any one period of an address period are different from each other. In at least one of a plurality of subfields constituting one frame, a width of a first sustain signal of a plurality of sustain signals supplied during a sustain period is larger than a width of each of the remaining sustain signals.

  • Publication number: 20100265240
    Abstract: A plasma display device is provided. The plasma display device includes a plasma display panel (PDP) which has an upper substrate, a lower substrate, a plurality of scan electrodes and a plurality of sustain electrodes that are disposed on the upper substrate, and a plurality of address electrodes that are disposed on the lower substrate; and a driving unit which applies driving signals to the scan electrodes, the sustain electrodes and the address electrodes. The driving unit drives the scan electrodes in units of scan electrode groups during an address period, and applies different voltages to the scan electrodes, thereby enabling an address discharge to be stably performed.

  • Publication number: 20100238152
    Abstract: A method of driving a plasma display panel (PDP) and a plasma display device using the same are provided. In the plasma display device, a plurality of scan electrodes formed on the PDP are divided into first and second groups to supply scan signals. When a scan bias voltage is higher in a first subfield in first and second subfields, lowermost voltages of reset signals are higher in the second subfield. According to the plasma display device, when the plurality of scan electrodes are divided into at least two groups to be driven, the lowermost voltages of the reset signals are controlled in accordance with a scan bias voltage so that it is possible to reduce address erroneous discharge in accordance with the loss of wall charges, to prevent the generation of brilliant points, and to improve the picture quality of a displayed image.

    Abstract: The present invention relates to a plasma display apparatus. In an aspect, the plasma display apparatus includes a plasma display panel including a plurality of scan electrodes and sustain electrodes formed on an upper substrate, and a plurality of address electrodes formed on a lower substrate, and a driver for supplying driving signals to the plurality of electrodes. The plurality of scan electrodes may be divided into first and second groups. An address period may include first and second group scan periods in which scan signals are supplied to the first and second groups, respectively. Scan bias voltages supplied to the first and second groups in at least one of the first and second group scan periods may be different from each other. Time points at which data signals are supplied to first and second of the plurality of address electrodes in at least one of the first and second group scan periods may be different from each other.
