Abstract: Operation of an AC plasma display panel requires the three control operations of write, erase, and sustain. Sustain, write and erase signals are stored in a plurality of sections in a storage device and the sections are selectively accessed according to the specific operation to be provided to the plasma panel display. The control signals stored within a given sequence are selected so that no dimming occurs during write and erase operations. A brightness control is provided to modulate the average repetition rate of signals applied to the plasma display panel. In this manner, a plurality of flicker-free brightness levels may be chosen.
