Abstract:
A plasma display panel, wherein main electrodes (X, Y) are respectively divided into pieces(41A, 41B, 42A, 42B) in the row direction, and electrode gaps are arranged at the boundaries between discharge cells (C) in the row direction. Even if a pair of conductors that sandwich an electrode gap, namely the first group (41A, 42A) of the main electrodes and the second group (41B, 42B) are controlled at an equal potential, the discharge generated between the first and second groups of the main electrodes hardly spreads out to the second group.

Abstract:
If Wb, Wg, and Wr are the widths of blue, green, and red discharge cells, and Db, Dg, and Dr are the widths of the address electrodes (15b, 15g, 15r) corresponding to the respective colors, the relationships among them are given by Wb>Wg>Wr, and Db>Dg>Dr. Therefore the amounts of charge accumulated in the respective color discharge cells can be adjusted by write discharge, and the complete operation write voltages of the discharge cells of the colors are uniformed. As a result, an AC plasma display panel free from erroneous discharge and discharge flicker and having a high display quality, especially an improved white displays quality is provided.
Abstract:
In a three-electrode AC plasma display panel, a plurality of X electrodes (22) and a plurality of Y electrodes (23) are alternately arranged parallel to each other on one of two, front and rear insulating substrates (20, 21) opposing each other, and a plurality of data electrodes (29) are arranged on the other insulating substrate to cross the X and Y electrodes (22, 23) at right angles. In this panel, cell separation partition walls (33) are arranged on the front insulating substrate, on which the X and Y electrodes (22, 23) are arranged, along the X and Y electrodes (22, 23). In a driving method for the three-electrode AC plasma display panel, progressive display is performed depending on whether discharge simultaneously occurs between all the adjacent pairs of X and Y electrodes (22, 23).
Abstract:
A plasma display panel, wherein a plan view of each of partitions for partitioning discharge spaces for each column has a band-like shape having projections extending in a row direction and a column space constituting a one-column discharge space is locally narrowed at each between-rows boundary. The provision of narrowed portions in a column space can restrict the spread of surface discharge in a column direction and prevent lowering in resolution. Projections extending in a row direction from a partition can increase the side surface area of a partition to increase a luminous area and therefore a brightness when a fluorescent material layer is provided on the side surface of a partition.
