Abstract:
A plasma display panel for preventing a discharging operation in a non-displaying area and thus progressing the contrast ratio according to the present invention is disclosed. The plasma display panel comprises a first substrate and a second substrate which are provided with each of inner faces opposite to each other. Between the first and second substrates, barrier ribs arranged toward a first direction are separated parallel to each other with a space. On the inner face of the first substrate, first electrodes are arranged parallel with each other toward a second direction which is orthogonal with the first direction. In addition, dot type second electrodes, which are connected with a pair of first electrodes and are exposed to a space between the pair of first electrodes, are arranged on the inner face of the first substrate. Between the barrier ribs on the inner face of the second substrate, there are placed third electrodes which are arranged parallel with the first direction. Here, a unit cell is defined as an area which is limited by the barrier ribs and includes a pair of first electrode.
Abstract:
A color two substrate alternating plasma display panel. The panel includes two tiles joined together so as to be opposite each other and defining a space therebetween. The space is filled with gas. One of the tiles has column electrodes which are approximately parallel, separated by a spacing and covered with at least one phosphor region. The other tile has at least one row electrode. The phosphor regions are provided with at least one recess placed at the intersection of a column electrode with the row electrode. A color pixel is formed by neighboring recesses lying within the same row electrode in adjacent phosphor regions. In order to obtain better light efficiency, the distance separating two adjacent recesses lying within adjacent phosphor regions and belonging to the same pixel is greater than the spacing so that space has a thickness greater than that required when two recesses are separated by approximately the spacing.
Abstract:
An object of the present invention is to provide a phosphor capable of improving the light emitting efficiency of a plasma display panel and restraining the deterioration of luminance and a change in chromaticity with the passage of time, and also provide a manufacturing method of this phosphor and the plasma display panel using this phosphor. To achieve this object, the surfaces of phosphor particles for a plasma display panel are covered with a metallic oxide generated by the hydrolysis of a metallic alkoxide. A manufacturing method of the phosphor particles for the plasma display panel is characterized in that the metallic alkoxide is attached to the phosphor particle surfaces and is burned. In this manufacturing method, the phosphor particle surfaces are covered with a close film of the metallic oxide. The plasma display panel uses the phosphor particles having surfaces covered with the metallic oxide.

Abstract:
This invention relates to a method for manufacturing a flat display panel device suitable for being applied to a plasma display panel and the like. In the method comprising forming a barrier-ridge-forming layer over a whole surface of a substrate having an electrode pattern, then removing from barrier-ridge-forming layer the unnecessary portions by jetting an abrasive, so as to form a barrier ridge, and further filling the removed portions with fluorescent paste layer and removing from fluorescent paste layer the unnecessary portions by jetting the abrasive until a given discharge space can be kept. Organic material particles coated with an inorganic material are used as the abrasive for removing the barrier-ridge-forming layer and/or the fluorescent paste layer. By coating the organic material with the inorganic material, the abrasive particles become roundish. Thus, even if these are used as the abrasive, it is not feared that they injury the surfaces of the glass substrate and the address electrode.
