(57) A circuit for performing sustaining and pulsing operations for an AC plasma panel
is disclosed, wherein two MOSFET transistors are used to alternatively, selectively
provide a two level output signal. The circuit requires only a single logic input,
thus preventing both transistors from conducting simultaneously, and features full
slew rate control of the output. The drive circuitry is improved so that the waveforms
applied to the panel electrodes to perform the sustain, write, erase, and bulk-erase
functions are simplified to comprise a sequential series of rectangular waves, and
only one high voltage power supply is required. High voltage is supplied to the driver
chips only when they are to perform a write or erase function, thus greatly reducing
the amount of power which must be dissipated in the driver chips.
