Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
114 words
A gas discharge picture diSplay panel comprising a pair of spaced plates defining a hermetically sealed enclosure therebetween filled with an ionizable gas, a first set of electrodes lying in a first plane within said enclosure and extending in a first direction therein, said first set of electrodes being divided into groups, a second set of electrodes within said enclosure lying in a second plane spaced from said first plane and extending in a direction forming an angle with said first direction, and a common conductor lying in a plane spaced from said first plane connecting the electrodes in each of said groups and extending hermetically through said enclosure to a source of potential.
Claim 2
Dependent Claim
114 words
A gas discharge picture diSplay panel comprising a pair of spaced plates defining a hermetically sealed enclosure therebetween filled with an ionizable gas, a first set of electrodes lying in a first plane within said enclosure and extending in a first direction therein, said first set of electrodes being divided into groups, a second set of electrodes within said enclosure lying in a second plane spaced from said first plane and extending in a direction forming an angle with said first direction, and a common conductor lying in a plane spaced from said first plane connecting the electrodes in each of said groups and extending hermetically through said enclosure to a source of potential.
Claim 3
Dependent Claim
43 words
A gas discharge picture display panel as claimed in claim 1 further comprising a plate disposed between said first and second set of electrodes having apertures therein at each of the points of intersection of the electrodes of said first and second sets.
Claim 4
Dependent Claim
29 words
A gas discharge picture display panel as claimed in claim 2 further comprising a third set of electrodes in a third plane within said enclosure which constitute auxiliary anodes.
Claim 5
Dependent Claim
62 words
A gas discharge panel as claimed in claim 2, wherein the common conductors are parallel to and in the same plane as the second set of electrodes and are electrically conductively connected to the electrodes of the first set by means of connection members which are provided in the apertures of the plate present between the first and second set of electrodes.
Claim 6
Dependent Claim
16 words
A gas discharge panel as claimed in claim 4, wherein the connection members are cup-shaped springs.
Claim 7
Dependent Claim
29 words
A gas discharge panel as claimed in claim 5, wherein the common conductors are present on a side of a picture plane determined by the second set of electrodes.
