Abstract:
A partition member for a gas discharge display panel having a front substrate with at least one main discharge electrode spaced from a back substrate having at least one auxiliary discharge electrode so as to delimit a gap therebetween. The partition member is adapted to extend substantially parallel to and between the front and back substrates for forming a main discharge space on a front substrate side and an auxiliary discharge space on a back substrate side, the partition member being a metal material member. A gas discharge display panel incorporates the partition member and a system is provided for driving the gas discharge display panel. Also, a manufacturing method is provided for the partition member and gas discharge display panel.
Abstract:
Front substrate and back substrate of a PDP are respectively in a warped state such that a central portion of each substrate projects more frontwards than peripheral portions of the respective substrate, so that the front surface is convex. A stress remains in the substrates such that the two substrates are pressed to each other with an elastic deformation. In preparing the two substrates, the front panel and back panel are respectively warped towards each other so that the facing inner surfaces are convex in being sealed with each other. A height difference ratio of the central portion from a central part of a short side of the back substrate is preferably less than 0.16%. A height difference ratio of the central portion from a central part of a short side of the front substrate is preferably less than 0.06%. Difference of the height difference ratios of the back substrate and the front substrate is preferably 0 to 0.1 point.
Abstract:
The first object of the present invention is to provide a PDP with improved panel brightness which is achieved by improving the efficiency in conversion from discharge energy to visible rays. The second object of the present invention is to provide a PDP with improved panel life which is achieved by improving the protecting layer protecting the dielectrics glass layer. To achieve the first object, the present invention sets the amount of xenon in the discharge gas to the range of 10% by volume to less than 100% by volume, and sets the charging pressure for the discharge gas to the range of 500 to 760Torr which is higher than conventional charging pressures. With such construction, the panel brightness increases. Also, to achieve the second object, the present invention has, on the surface of the dielectrics glass layer, a protecting layer consisting of an alkaline earth oxide with (100)-face or (110)-face orientation. The protecting layer, which may be formed by using thermal Chemical Vapor Deposition (CVD) method, plasma enhanced CVD method, or a vapor deposition method with irradiation of ion or electron beam, will have a high sputtering resistance and effectively protect the dielectrics glass layer. Such a protecting layer contributes to the improvement of the panel life.
Abstract:
A discharge display device wherein a gas-tight space defined by two plates and a sealing member is divided into a plurality of discharge chambers by partition walls formed on one of the two plates, and height adjusting layers are interposed between end faces of the respective partition walls and an inner surface of the other plate. Each height adjusting layer is formed from a material which has a softening point not lower than that of the sealing member and which is softened at a sealing temperature at which the two plates are bonded together by the sealing member. The height adjusting layers, which assure gas-tight separation of the discharge chambers, may replace upper end portions of the partition walls. Alternatively, the partition walls may be entirely formed from the above-indicated material. Also disclosed is a process of fabricating such a discharge display device, wherein height adjusting layers are softened at the sealing temperature when the two plates are bonded together with the melting of the sealing member.
