ABSTRACT:
A plasma charge display device having a channel containing an ionizable medium with the channel defining an endless length as in the case of a circular channel. At least one input electrode is located in a first position, and transfer electrodes extend away from the input electrode on opposite sides thereof completely along the length of the channel. Gas ionization results in the formation and shifting of light emitting areas in either direction relative to the position of the input electrode. The transfer electrode positions are related to the input electrode position in a manner such that the light emitting areas can be shifted through the position of the input electrode from one side to the other thereof.
