Abstract: A plasma display panel is provided in which a reliability of addressing is ensured, a flicker is reduced and the area that a cross talk can spread in the column direction is decreased so that a fluctuation of the display can be reduced. The plasma display panel has a first display electrode and a second display electrode that make an electrode pair for surface discharge. The first and the second display electrodes share one electrode for display of neighboring two rows. A partition is provided that divides a discharge gas space in the column direction only in the area where the first display electrode that is not used as a scanning electrode is positioned.

Abstract: A plasma display panel is provided that can prevent interference of discharge between rows securely without reducing operation margin. Plural partitions being at a distance from each other define a discharge space of each column in the screen. The column space defined by the partitions is narrowed periodically along the column direction. A surface discharge gap is formed at each enlarging portion of the column space. A pair of plural main electrodes is provided for surface discharge. Each of the main electrodes includes a belt-like bus portion extending in the row direction of the screen and plural gap forming portions protruding in the column direction from the bus portion toward the enlarging portion in each column space.

Abstract: Undue power consumption is reduced in the capacitance between data electrodes during addressing in a display panel. The power consumption associated with the capacitance is reduced to half as compared with the conventional panel, because the current associated with the discharge of the capacitance is independent of the power supply in the case of a combination of “L reset”, where the capacitance between data electrodes is discharged through a backward current path on the current sink terminal side, and “H reset”, where the capacitance between data electrodes is discharged through a backward current path on the current supply terminal side.

Abstract: The gas discharge panel according to the present invention includes a pair of substrates, a plurality of barrier ribs, a sealing member, and two gas flow barriers. One of the substrates has a first vent hole and a second vent hole provided in a peripheral portion thereof for intercommunication between the inside and outside of the panel. The at least two gas flow barriers are provided between the sealing member and the barrier ribs located on opposite sides of an arrangement of the barrier ribs so that a gas introduced from the first vent hole flows through inter-rib spaces defined between adjacent pairs of barrier ribs and is expelled from the second vent hole.

Abstract: The present invention provides a method of forming a plurality of barrier ribs each having an elongate configuration in plan and extending in the same direction within a display area for fabrication of a display panel. The method comprises the steps of forming a mask for cutting, having a masking pattern corresponding to the plurality of barrier ribs on a rib material layer, and removing portions of the rib material layer by jetting a cutting medium thereto, wherein the masking pattern is configured such that a plurality of elongate portions corresponding to the respective barrier ribs each extend across the display area to the outside of the display area and a spacing between adjacent end portions of elongate portions is smaller than a spacing between adjacent elongate portions within the display area.

Abstract: A method of forming barrier ribs of a display panel includes the steps of forming a layer of a dielectric paste containing a powdery component and a binder component as a layer of a barrier rib material in a predetermined thickness on a substrate, forming a mask pattern on the dielectric paste layer, jetting a cutting medium onto the dielectric paste layer through the mask pattern to partially cut the dielectric paste layer to thereby form a cut barrier rib layer, and sintering the cut barrier rib layer to make barrier ribs, wherein, prior to forming the mask pattern, a bind film is formed for fixing the powdery component in a free state on the surface of the dielectric paste layer.

A plurality of separator walls are spaced apart from each other and extend along the second electrodes, dividing a discharge space into a plurality of channels extending along respective, second electrodes.

A fluorescent material is coated in each channel, the colors emitted from the fluorescent material being identical in each channel. A gas discharge takes place selectively at the wide portions in cooperation with the respective first and second electrodes.
