ABSTRACT:
A display system is disclosed comprising a processor, a plasma panel subassembly including generally orthogonally related arrays of conductors and drive circuits for the same, and a read-write memory for storing the image data provided by the processor and delivering drive information to the panel subassembly. Control logic provides arbitration for time sharing the operation of the memory between communication with the processor and with the panel subassembly, storage of modified data tags means associated with the memory operation, and means under the control of the modified data tag means to control update erase and write operations of the panel subassembly on an as-needed individual pel line basis.
