Abstract
Write pulses are applied to the cells of a plasma display panel to repetitively establish the cells in respective temporary ON states in which the wall voltage stored at each cell decays with each applied sustain pulse. The average number of sustain cycles over which a particular cell remains in the temporary ON state, and thus its perceived brightness, is controlled by controlling the intra-sustain-cycle time occurrence of the write pulses applied thereto.
