ABSTRACT:
A d.c. gas discharge display panel consists of a rectangular array of discharge cells suitable for displaying alphanumeric characters surrounded by a circular array. The two arrays share one common set of conductors and are addressed sequentially by reducing the potential on the common conductors in turn by a glow transfer device extending around the circular array. The other conductors of the circular array may be commoned to result in a radial pointer whose position around the rectangular array can be changed.
