ABSTRACT:
A gas discharge device, including an interface and addressing means connected to a pair of opposed electrode arrays to energize a plurality of discharge cells, each cell including proximate electrode portions of at least one electrode in each opposed array, the dielectric charge storage member insulating at least one of the proximate electrode portions from the gas. A sustainer voltage source generates an alternating polarity wave form which maintains a discharge sequence in all cells which are in the "on" state. In accordance with the present invention, an enhancement pulser means generates an enhancement voltage pulse which is cyclically superimposed on the sustainer wave form. The enhancement pulse has the same polarity as the sustainer wave form and is generated to coincide with each discharge of the cells in the "on" state to increase the brightness and performance of the gas discharge device.
