When an AC plasma display panel is fabricated with uniform conductor line widths, the glow discharge spreads along the conductors as a function of the sustain voltage to maintain a substantially constant current density. When a cell is selected, this glow spread increases interaction between adjacent cells as picture elements, decreasing the operating margin (Vs (max) - Vs (min)) of the panel. This glow spread can be minimized by selecting a discharge gap which is less than the distance between adjacent conductors. However, since the tolerance on the gap becomes larger as the gap is decreased, the anticipated improvement in panel margin is offset.
