Abstract
Apparatus for providing a visual information screen of the type formed from a plurality of gas cells wherein electrical voltages are capacitively coupled to selected cells to cause gas ignition and subsequent light emisson. The present invention comprises an improvement over prior art devices in that it utilizes a single plane of parallel spaced conductors to ignite gas in channels perpendicularly aligned with respect to the conductors and located above the conductor plane, wherein a gas cell is defined by the region within a channel between two parallel conductors, and further in that it utilizes a special conductor geometry to initially ignite a gas cell and introduce data into the screen with only a single voltage-magnitude source.
