Abstract

As shown in Fig. 1, an AC gas panel is fabricated in a manner so as to have the discharge confined between the electrodes on the front plane. The electrodes on the front plane are designated a, b, c, d, and e as indicated at the right-hand portion of the drawing. The rear plane electrodes 1-9 are used for write and erase pulses.

AC Gas Panel with Sustaining Electrodes on a Single Plane

As shown in Fig. 1, an AC gas panel is fabricated in a manner so as to have the discharge confined between the electrodes on the front plane. The electrodes on the front plane are designated a, b, c, d, and e as indicated at the right-hand portion of the drawing.

The rear plane electrodes 1-9 are used for write and erase pulses.

Fig. 2 shows a side view of the panel shown in Fig. 1. Front plate 1 has deposited thereon metallurgy of the configuration shown by a-e in Fig. 1. The metallurgy on back plate 5 is composed of the vertical write/erase lines depicted by 1-9 in Fig. 1. Seal 3 acts to enclose an appropriate gas, such as neon/argon, between plates 1 and 5.

In the operation of the panel, electrodes a-e have applied thereto sustaining voltage pulses, and electrodes 1-9 have applied thereto write/erase pulses. If, for example, a sustaining voltage pulse is applied to electrodes b and c, no discharge occurs. However, if a write pulse is applied to electrode 3, a discharge occurs within the region where electrodes b, c, and 3 coincide and continues in response to sustain pulses, even after the write pulse has subsided. As is evident, the discharge between electrodes b and c is confined to the region where electrodes b, c, and 3 coincide, due to the geometry of electrodes b and c in this region.

In like fashion, other points or regions within the active region of the gas panel may be written by applying appropriate write pulses to write lines 1-9. One of the difficulties encountered in fabricating conventional large AC gas...
