Abstract:
Almost only choice by a secondary electron emission layer/protection layer covering the dielectric layer of an AC type PDP has been magnesium oxide (MgO) that is unstable during the production process and difficult to form, thus posing a serious production problem. An AC type PDP constructed such that, instead of covering the surface of a dielectric layer (3) with a dielectric material such as MgO, an insular electrode (4) is made by forming a conductive material such as nickel, aluminum, magnesium and lanthanum hexaboride into an insular shape, and the insular electrode (4) is allowed to capacity-couple with a lower-layer bus electrode (9) by means of an electrostatic capacity formed by a dielectric layer (3) to operate the insular electrode (4) as a sustained electrode.
Abstract:
In a plasma display panel having a front glass substrate on which row electrode pairs and column electrodes are provided, a second additional dielectric layer projects from a portion of the rear-facing face of a first additional dielectric layer opposite to a transverse wall member of the partition wall toward a back glass substrate, and extends in the row direction to provide a block between the discharge cells C adjoining to each other in the column direction on both sides of the transverse wall member. The column-electrode width of the second additional dielectric layer is smaller than that of the transverse wall member of the partition wall.
Abstract:
A front glass substrate is opposite a back substrate with a discharge space in between. On the rear-facing face of the front glass substrate are provided a plurality of row electrode pairs each extending in the row direction and regularly arranged in the column direction to individually form display lines; and a plurality of column electrodes each extending in a direction at right angles to the row electrode pairs and separated from the row electrode pair by a first dielectric layer. A partition wall partitions the discharge space into discharge cells each opposite the opposed transparent electrodes of the row electrode pair. In the plasma display panel structured in this manner, the back substrate is constituted of a metal plate having the surface covered with an insulation layer.

Abstract:
A first electrode group and a second electrode group each being formed by planarly arraying a plurality of electrodes on a common substrate are arrayed such that the electrodes cross over through an insulating layer. A common discharge electrode portion is arranged between each pair of adjacent electrodes of the first electrode group to be opposite to the pair of electrodes, and plasma discharge portions are formed at opposing portions of the respective discharge electrode portions and the opposite portions of each of the pairs of electrodes opposite to the discharge electrode portions. Thus, a problem of decreases in width of electrodes and inter-electrode interval caused by an increase in definition in a planar-type plasma discharge display device is solved, and at the same time, without using a complex signal processing circuit, the display drive of the planar-type plasma discharge display device and a high-luminance display drive are performed without causing any image degradation.
