ABSTRACT:
A display panel includes a series of linear conductive elements, operable as glow cathodes, and separated into first and second portions by means of an insulating barrier extending along and overlaying the series of cathodes. A first anode is disposed adjacent to the series of cathodes and is operable with the first portions thereof in a scanning operation wherein each such portion of each cathode is energized in turn. A second anode is disposed in operative relation with the second portions of the cathodes and is adapted to be energized at selected times during the operation of the first portions of the cathodes to cause glow to spread from glowing first portions to the associated selected second portions.
