    Abstract: The disclosure teaches using at least two orthogonal arrays of complicated shaped glass rods or very large fibers-like structures (from here in referred to as fibers) with wire electrodes to fabricate plasma displays with plasma cells larger than 0.05 mm3 in volume. (The volume of a plasma cell is defined by the width of the plasma channel times the height of the plasma channel times the pitch of the pair of sustain electrodes.) To increase the size of the bottom fiber and keep the addressing voltage constant or to reduce the addressing voltage, the address electrode is moved from the bottom of the channel up into the barrier rib. Moving the address electrode up into the barrier rib will reduce the distance, d, between the address electrode and the sustain electrodes, thus increasing the electric field of the addressing pulse.

The line and the display electrode are arranged alternately each other on the front substrate. Further, the device comprises a rear substrate, which has a plurality of data electrodes extending in a direction perpendicular to the display electrodes. The rear substrate forms a discharge space between itself and the front substrate, defines a gap of the discharge space, and has a partition in a belt shape placed between adjoining data electrodes. Furthermore, the rear substrate has a barrier between the partitions at a position facing to the non-display portion so as to have width corresponding to the non-display portion, form a gap between itself and the front substrate, and prevent an error discharge between the display electrodes.

  • Patent number: 6577069
    Abstract: An AC type plasma display panel is designed so as to have the relationships of Wb>Wg>Wr and Db>Dg>Dr, where Wb, Wg and Wr denote the widths of blue, green and red discharge cells and Db, Dg and Dr denote the widths of address electrodes (15b, 15g and 15r) corresponding to respective colors. As a result, it is possible to adjust the electric charge stored in the discharge cells due to a write discharge according to colors, thereby making complete lighting write voltages of the discharge cells uniform. This achieves the AC type plasma display panel with an excellent display quality that has less occurrence of erroneous discharge and discharge flicker and an improved white display quality.
