Abstract
Abstract A charge transfer plasma display device includes plural transfer electrodes arranged in an alternating fashion on opposite walls of a plasma-filled enclosure, so that the electrodes on one wall are interlaced between those on the other wall. Plural groups of write electrodes are disposed at one end of the transfer electrode arrangement, with each write electrode in each group being connected in parallel with an associated write electrode in every other group. Disposed between the write electrodes and the transfer electrodes are plural input shift electrodes. The input shift electrodes have different lengths so that a different number of such electrodes are disposed between each group of write electrodes and the transfer electrodes. In operation, the input shift and transfer electrodes are successively energized in a continuing sequence, and the write electrodes are selectively energized, in coordination with the energization of the shift electrodes, to create "pips" of light. Alternatively, the write electrodes can be successively energized and the shift electrodes selectively energized in coordination therewith.
