Abstract
Abstract A three-dimensional gas display device wherein a plurality of gas discharge matrices are stacked forming a three-dimensional array. Each of the gas discharge matrices is formed by two planes of parallel glass enclosed wires, the glass enclosed wires of one plane running perpendicular to the other plane of glass enclosed wires. A gaseous element is placed between the parallel planes of glass wires. Means are provided for applying a potential difference between the two wires intersecting at any point in the three-dimensional array causing a continuous electric discharge at this point. By correctly selecting the intersecting points, a three-dimensional design can be displayed.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
94 words
A three-dimensional gas display device including: a plurality of parallel gas discharge matrices, each matrix including: a first set of parallel glass enclosed wires; a second set of parallel glass enclosed wires perpendicular to said first set of wires, the plane of said second set substantially parallel to the plane of said first set of enclosed wires; and an ionizable gas medium disposed between the planes of said sets of wires; control means applying a potential difference sufficient to cause a discharge between two selectable intersecting wires in one of said plurality of matrices.
Claim 2
Dependent Claim
94 words
A three-dimensional gas display device including: a plurality of parallel gas discharge matrices, each matrix including: a first set of parallel glass enclosed wires; a second set of parallel glass enclosed wires perpendicular to said first set of wires, the plane of said second set substantially parallel to the plane of said first set of enclosed wires; and an ionizable gas medium disposed between the planes of said sets of wires; control means applying a potential difference sufficient to cause a discharge between two selectable intersecting wires in one of said plurality of matrices.
Claim 3
Dependent Claim
25 words
A device as in claim 1 wherein all of said parallel gas discharge matrices are in a single box, transparent on at least one side.
Claim 4
Dependent Claim
20 words
A device as in claim 2 wherein said ionizable gas medium can freely flow between said parallel gas discharge matrices.
