Plasma panel with dynamic keep-alive operation utilizing a lagging sustain signal

摘要

An a-c plasma display panel including apparatus for driving the keep-alive cell sustain signal circuits in a non-fixed relation with address pulses. By constraining the keep-alive sustain signal to selectively lag the addressing signal by an amount dependent on the address of a cell being addressed it is possible to refine the control over voltage margins afforded by dynamic keep-alive while simplifying the circuitry required to produce it.
