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.

Dependent claims

A charge transfer plasma display device comprising:

an enclosure having a plurality of parallel channels containing an ionizable medium, each of said channels being defined within a walled structure, at least one wall thereof being transparent;
a plurality of write electrodes provided on at least one inside wall surface, said write electrodes being arranged in a plurality of groups;
means for electrically connecting each one of said write electrodes belonging to each group to an associated write electrode in each of the other groups of write electrodes;
a plurality of transfer electrodes arranged in alternating sequence and offset from one another on opposite inside wall surfaces;
a plurality of input shift electrodes arranged in alternating sequence and offset from one another on opposite inside wall surfaces, said input shift electrodes being located between said write electrodes and said transfer electrodes such that the number of said input shift electrodes present in plan view between each one group of said write electrodes and said transfer electrodes is different from the number of said input shift electrodes present in plan view between every other group of said write electrodes and said transfer electrodes;
means for applying pulses in a predetermined successive manner to said transfer electrodes;
means for applying pulses selectively to one of said input shift electrodes and said write electrodes;
and
means for applying pulses in a predetermined successive manner to the other of said input shift electrodes and said write electrodes.
