  • Patent number: 8421713
    Abstract: It is an object to provide a driving method of a plasma display panel, whereby a dark contrast can be improved while suppressing an erroneous discharge. In a resetting step in a first unit display period, while a first reset pulse having a predetermined peak electric potential is applied to one of first row electrodes of row electrode pairs formed in the PDP, a second reset pulse having a peak electric potential smaller than that of the first reset pulse is applied to the other of the first row electrodes. In the resetting step in a second unit display period subsequent to the first unit display period, a second reset pulse is applied to each of the one and the other of the first row electrodes.

  • Patent number: 8203507
    Abstract: A drive method of a plasma display panel that can increase the dark contrast, without causing a discharge failure. When a discharge cell that assumes a black display state in a first field from among first and a second fields that are adjacent in time and switches to a display state representing a brightness other than black in the second field is detected as a lighting transition cell, at least one drive of the below-described first and second forced lighting drives is executed. In the first forced lighting drive, the lighting transition cell is forcibly set into the lighting mode only in the address process of a predetermined subfield within the field in the first field. In the second forced lighting drive, an adjacent discharge cell that is adjacent to the lighting transition cell is forcibly set into the lighting mode only in the address process of the predetermined subfield in the second field.

    Abstract: A plasma display panel and a drive method therefor, which can enhance a representation capability when displaying a dark image. The plasma display panel includes fluorophor layers containing magnesium oxide. The drive method includes a reset step to initialize all the pixel cells into states of one of a light-up mode and a light-off mode, and an address step in which the pixel cells are caused to perform address discharges selectively in accordance with pixel data, which are successively executed in each of a head subfield and a second subfield within a one-field display period.
