Abstract:
A surface-discharge type PDP includes plural main electrode pairs formed of first and second sustain electrodes arranged on a first substrate. Each pair extends along a line direction, and the first and second sustain electrodes are in parallel and adjacent to each other. Plural address electrodes arranged on a second substrate opposing the first substrate via a discharge space, each extending along a row direction, a matrix corresponding to a screen to be displayed is formed with the main electrodes and address electrodes, the address electrodes are othogonal to the main electrodes, each of the address electrode is divided into, for example two partial address electrodes separated from each other by a border line located between adjacent main electrode pairs, whereby the screen is divided into two partial screens, wherein a first clearance between the partial address electrodes is substantially larger than a second clearance between main electrode pair adjacent across the border line. The arrangement order of the first and second sustain electrodes may preferably be such that first sustain electrodes of the first and second partial screens face each other via the border line, and the partial address electrodes may not cross over the first sustain electrodes nearest to the border line.
Abstract:
A plasma display comprises a face plate; at least one energy source; a first layer comprising pigmented phosphors; and a second layer comprising non-pigmented phosphors. The at least one energy source emits energy that is capable of exciting the non-pigmented phosphors of the second layer. Thus, the non-pigmented phosphors of the second layer emit energy comprising visible light. The first layer comprising the pigmented phosphors acts as a filter to filter the emissions from the non-pigmented phosphors of the first layer. Therefore, the plasma display has at least an increase in contrast of the energy emitted therefrom.
Abstract:
An AC plasma display panel includes a plurality of opaque scanning electrodes (3b, 3c) and maintaining electrodes (4b, 4c) which are parallel to each other, formed on a first glass substrate (1) at the display side of the display, a plurality of ribs (9) formed on a second glass substrate (7) and arranged orthogonally to the scanning and maintaining electrodes, a data electrode (8) formed on the second glass substrate (7), positioned between the ribs and arranged parallel to the ribs (9), wherein a discharge cell (2) is defined by dividing the space between two ribs (9) and includes at least two of the scanning electrodes (3b, 3c) and at least two of the maintaining electrodes (4b, 4c). The maintaining discharge is generated between the two scanning electrodes (3b, 3c) and the two maintaining electrodes (4b, 4c). Consequently, a discharge region can be widened without decreasing the opening ratio, and an AC plasma display panel with high brightness and high efficiency can be obtained. In addition, because the display does not required to use electrodes in which a transparent conductor and a bus electrode are connected electrically, both the number of production steps and the cost of production can be decreased.
Abstract:
In each of discharge cells of a color plasma display panel, a data electrode is formed so as to cover entire side walls and bottom of the cell. A fluorescent layer is also formed on an entire surface of the data electrode to improve brightness. The barriers are provided by forming a plurality of grooves a glass substrate to reduce flicker of a screen. The surface of the substrate is made black to improve a display contrast.

Abstract:
A plasma display panel of the surface discharge type in which a maintaining discharge is generated between electrodes formed on the same substrate, includes first and second insulating substrates separated from each other to form a discharge space therebetween. A spacer having a partition wall in the form of a grid is located between the first and second insulating substrates so as to partition the discharge space into a number of pixels. Electrodes for maintaining discharge are provided on the first insulating substrate, and phosphor is located on the second insulating substrate within each of the pixels. The first insulating substrate is located at a display side.

A plasma display panel (PDP) driven by a pulse memory type driving method. In the PDP, a display anode array is arranged on the inner surface of a rear plate to increase the effective light emission area, and a path of charged gas particles from an auxiliary cell to a display cell is formed along the rear plate to enhance the contrast ratio. As a result, high brightness and high contrast ratio can be obtained.
