ABSTRACT:
A circuit configuration for use with a small plasma panel to allow independent variation of the brightness level on a raster in addition to the information displayed by the raster. The gray scale level of all or part of the displayed information can be changed in response to a change in a sensed condition. The desired gray shade level or levels for a particular raster of digital information is stored in a simple memory. The data out of the memory is used by an E/W pulse gate to clock write pulses and erase pulses to the addressing circuitry of the plasma panel. The write or erase pulses then combine with the sustainer voltage waveform at each site to either strike, entinguish, or not change discharge state of each site as the plasma panel as the individual site locations are sequentially addressed.
