Abstract
An AC plasma display with enhanced resolution is disclosed. The display includes at least three electrodes per pel with at least one electrode electrically connected in common with other electrodes for the purpose of providing common sustain signals to the pels. The common electrodes are divided into at least two interleaved sets so that adjacent vertical pels can be separately biased during the sustain phase. In accordance with one embodiment of the invention, sustain signals are applied in two phases alternatively to the sets of common electrodes. In accordance with another embodiment of the invention, the sustain signals are applied to both sets simultaneously, but with an opposite polarity.
