Abstract

This three-dimensional array of electrodes provides a three-dimensional gas discharge display device. Hermetically sealed box 7 has at least one transparent side 9. Box 7 contains a number of stacked matrices. Each matrix is constituted by two parallel planes, each consisting of a set of wires in the second plane. Box 7 is filled with an ionizable gas.

Three Dimensional Gas Panel

This three-dimensional array of electrodes provides a three-dimensional gas discharge display device. Hermetically sealed box 7 has at least one transparent side 9. Box 7 contains a number of stacked matrices. Each matrix is constituted by two parallel planes, each consisting of a set of wires in the second plane. Box 7 is filled with an ionizable gas.

The X-Y-Z display control and power supply 11 selects an electrode pair from the wires 1 and 3. Slightly more than half the firing potential of different polarities is impressed on each of the electrodes associated with a given intersection. At the intersection point a discharge is initiated. Immediately after discharge the voltage on the electrodes is lowered to slightly more than half the sustaining voltage. Ionizable gas freely moves between electrodes resulting in a uniform firing potential for all electrode pairs. The electrodes are glass encapsulated to prevent deterioration. The power supplied to the electrodes is AC to prevent a charge build-up on the insulating glass.
