Abstract
Abstract A high resolution gaseous discharge display comprises an encapsulated panel array of bistable charge storage areas defining linearly shaped discharge cells or sites, each cell being defined by a pair of congruent linear portions formed by generally orthogonally arranged conductors insulated from direct contact with the gas by a dielectric, which, when properly energized, produce a confined gaseous discharge in the selected cell. The cells are arranged in character font areas in columns and rows at the intersections of groups of the conductor lines, the conductors being configured at the character positions to define linear cells constituting character font strokes or elements.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
185 words
In a character display comprising a display panel having a voltage energizable display medium in a plane medially therewithin, first and second arrays of conductors in relatively outer planes of said panel embracing said medium, means connected individually to said arrays to provide matrix initiation, maintenance and extinction of operative voltage stresses within said medium at areas of congruence between conductors of said first array with conductors of said second array, the improvement comprising said first array comprising a plurality of multiple conductor groUps, each group corresponding to a column of character positions in said display, said second array comprising a plurality of multiple conductor groups, each group corresponding to a row of character positions individually congruent with character positions with said columns of character positions, each of the conductors of said first group and said second group at said character positions being configured to have linear congruence with each conductor of the other group in said character positions, the areas of linear congruence constituting character stroke positions individually selectable by matrix energization of a corresponding conductor in each of said first and second groups.
Claim 2
Dependent Claim
185 words
In a character display comprising a display panel having a voltage energizable display medium in a plane medially therewithin, first and second arrays of conductors in relatively outer planes of said panel embracing said medium, means connected individually to said arrays to provide matrix initiation, maintenance and extinction of operative voltage stresses within said medium at areas of congruence between conductors of said first array with conductors of said second array, the improvement comprising said first array comprising a plurality of multiple conductor groUps, each group corresponding to a column of character positions in said display, said second array comprising a plurality of multiple conductor groups, each group corresponding to a row of character positions individually congruent with character positions with said columns of character positions, each of the conductors of said first group and said second group at said character positions being configured to have linear congruence with each conductor of the other group in said character positions, the areas of linear congruence constituting character stroke positions individually selectable by matrix energization of a corresponding conductor in each of said first and second groups.
Claim 3
Dependent Claim
28 words
Apparatus in accordance with claim 1 wherein said conductors are formed with land areas in said character positions providing areas of linear congruence of character font element configuration.
Claim 4
Dependent Claim
52 words
Apparatus in accordance with claim 1 wherein said lines of said first array pass through said character positions in electrically parallel and non-intersecting relationship, and wherein said lines of said second array pass through said character positions in electrically parallel and non-intersecting relationship, whereby no line crossovers are required within either array.
Claim 5
Dependent Claim
73 words
Apparatus in accordance with claim 2 wherein said lines of said first array pass through said character positions in electrically parallel and non-intersecting relationship, and, wherein said lines of said second array pass through said character positions in electrically parallel and non-intersecting relationship, at least some of said land areas of at least one array including salient portions extending laterally of the corresponding conductor into congruence with land areas of the opposite array.
