Abstract
A plasma panel arrangement for storing, displaying and selectively shifting information from one place therein to another includes a panel filled with an illuminable gas, and horizontal and vertical parallel conductor arrays disposed on opposite sides of the panel, the coordinate intersections of the conductors defining gaseous discharge cells. The vertical conductors are sequentially driven by a multi-phase drive system, and the panel includes a plurality of data lines for entering information. The data as entered is sequentially shifted left or right in a horizontal direction in a single line display. In a multi-row display, the system provides left or right shifting of one character row while holding the display of the other character rows. The instant invention makes the plasma shift technology competitive in speed to X-Y matrix addressed panels, but at a much reduced circuit cost.
