Abstract
The state of a plasma or similar display cell is inverted by a two-pulse sequence comprising an inverting write pulse followed by an inverting erase pulse. The inverting write pulse switches a cell ON if it was OFF, while the inverting erase pulse switches the cell OFF if it was ON. The inverting write pulse is adapted to cause a gradual, rather than an immediate, wall voltage build-up so that the inverting erase pulse is of insufficient magnitude to turn a cell OFF if it was turned on by the inverting write pulse.
