Characteristics and diagnostics of horizontal long column plasma display panel

Summary form only given, as follows. The characteristics and diagnostics of horizontal long column plasma display are presented. The 7.5-inch test panels with 0.81 mm pixel pitch were fabricated and tested. For the proposed configuration, the gap (d=350um) between coplanar electrodes is greater than the height (1=130um) of barrier rib, while the gap is smaller than the rib height in conventional cell geometries. During the sustain period, the discharge is initiated between one of the coplanar electrodes and the address electrode (negative glow region). The developed discharge is propagates toward the other coplanar electrode (positive column region). Within the positive column region electric field is weaker and discharge efficacy is higher than those in negative glow region.
