Gas discharge panel, gas discharge device, and related methods of manufacture

A gas discharge panel having (a) a plurality of cells arranged in a matrix, each cell being filled with a discharge gas which is enclosed between a facing pair of substrates, and a plurality of barrier ribs interposed between the pair of substrates, and (b) plural pairs of display electrodes arranged on an inner surface of one of the substrates so as to extend in a row direction of the matrix across the cells, wherein image display is generated by a discharge fired between the plural pairs of display electrodes, each pair of display electrodes comprising:

• two bus lines, being parallel to each other and extending in the row direction of the matrix;
• one or more inner protrusions, being arranged within each cell on an inner side of one or both of the bus lines so as to protrude toward an inner side of an opposite bus line;
• one or more outer protrusions, being arranged within each cell so as to protrude from an outer side of one or both of the bus lines, at least a section of each of the inner and outer protrusions being positioned between two adjacent barrier ribs, and
• a panel driving circuit addressing and displaying an image, wherein the plural pairs of display electrodes are each formed of a scan electrode and a sustain electrode positioned immediately adjacent to each other and the panel driving circuit drives the image display by causing a discharge to be fired between addressed plural pairs of display electrodes, each pair of display electrodes receiving a sustain pulse during the image display.

A gas discharge device having plural pairs of electrodes arranged to face a discharge space filled with a discharge gas wherein a voltage is applied to each of the electrodes so as to fire a discharge between the plural pairs of electrodes and generate illumination, each pair of electrodes comprising:

• two electrode bases, being extended in a same direction;
• one or more inner protrusions, being arranged on an inner side of one or both of the electrode bases so as to protrude toward an inner side of an opposite electrode base;
• one or more outer protrusions, being arranged so as to protrude from an outer side of one or both of the electrode bases to enable a discharge between the inner protrusions to expand outward to the outer protrusions to provide increased illumination, and
• a panel driving circuit addressing and displaying an image, wherein the plural pairs of display electrodes are each formed of a scan electrode and a sustain electrode positioned immediately adjacent to each other and the panel driving circuit drives an image display by causing a discharge to be fired between addressed plural pairs of display electrodes, each pair of display electrodes receiving a sustain pulse during the image display.
