Plasma display panel with undulating separator walls

A plasma display panel, comprising:

• a matrix of a plurality of first electrodes and a plurality of second electrodes, said first electrodes and said second electrodes being straight and crossing each other;
• a plurality of separator walls, separated from each other and extending along a direction of said second electrodes, separating a discharge space so as to provide a plurality of channels therebetween, said separator walls being in a zig-zag shape, said second electrodes being disposed along said channel, a width of each channel periodically varying so as to provide alternating narrow and wide portions aligned along said first electrodes and along each of said channels, said narrow and wide portions of a common channel being spatially continuous through the common channel, electrical discharges being generated in selected said wide portions in cooperation with said first and second electrodes;
• and
• fluorescent materials disposed in said channels, a common florescent material emitting a respective color being disposed in each given channel.

A color plasma display panel of a surface discharge type, comprising:

• a matrix of a plurality of first electrodes and a plurality of second electrodes, said first electrodes and said second electrodes being straight and extending in first and second directions, respectively crossing each other;
• a plurality of spaced separator walls extending along a direction of said second electrodes and separating a discharge space into a plurality of channels, adjacent separator walls having a respective channel therebetween, said separator walls having a zig-zag configuration in the second direction, said second electrode being disposed along said channel, each channel periodically varying in width so as to provide alternating narrow and wide portions alternately aligned along each of said first electrodes and along each of said channels, said narrow and wide portions of a given channel being spatially continuous throughout a length of each channel, an electrical discharge being generated at a gap between two adjacent said first electrodes in said wide portion in cooperation with said first and second electrodes;
• and
• a fluorescent material disposed in each channel, colors emitted from said fluorescent materials in each given channel being identical.

A plasma display panel comprising:

• a matrix of unit display elements, arranged on a main surface of a substrate in rows in a first direction and lines in a second direction, generally perpendicular to the first direction;
• a plurality of separator walls formed on, and perpendicular to, the main surface of the substrate, extending along the first direction, said separator walls dividing a discharge space into a plurality of channels, adjacent separator walls being spaced in the second direction by said channels, each separator wall having a zig-zag configuration in a direction parallel to the main surface of the substrate, and each channel comprising a respective row of display elements, said separator walls being arranged such that a width of each channel varies periodically between a first width and a second width, each width in the second direction, said first width being less than a predetermined value and being smaller than said second width;
• fluorescent materials disposed in each said channel, said fluorescent material in a given channel being of a common color;
• and
• a plurality of display electrodes, extending along said second direction and crossing said channels, said display electrodes being arranged so that an electrical discharge is generated at a portion of said channel having said second width and no electrical discharge is generated at a portion of said channel having said first width.
