Abstract: A gas 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 which are grouped into rows and columns of character generating matrices. The vertical conductors are sequentially driven by a multiphase drive system (O1, O2, O3,), and the panel includes a plurality of data lines (D1, D2, D9 .... D37) for entering information, there being one data line for each four adjacent character positions. The data entered in each row may be sequentially shifted left or right in a horizontal direction, the arrangement providing left or right shifting of one character row while holding stationary the display of the other character rows.

Abstract: An improved write circuit for a gas panel produces a sequence of alternating polarity write pulses that are superimposed on a sequence of half cycle pulses of the sustain waveform. Thus the accumulation of charges on the walls of a light-emmitting cell that is required for a write operation is produced by a sequence of write pulses, and each write pulse is lower in amplitude than is required for a single write pulse. The write pulses are progressively shifted ahead in phase to further improve the operation.
