Abstract
Abstract There is disclosed a method of increasing the light transmission efficiency of a gas discharge device and assuring the electrical continuity of non-transparent printed conductors in the device, the conductors comprising transversely oriented row and column conductor arrays. The conductors of a conductor array on a plate forming the viewing side of the device are formed by sets of coplanar conductor elements spaced apart so that when a discharge occurs, an observer sees more of the center of the discharge which would ordinarily be partially hidden by a solid conductive line on the viewing side of the device. Likewise the conductor elements of a set may be connected at regular intervals to provide a plurality of electrically parallel routes for conduction in case a section of a conductor element of a set is discontinuous. The gas discharge is more visible since the applied field between selected conductor elements is across two conductors which are not congruent as seen by the observer.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
134 words
A method of increasing efficiency of light transmission and assuring electrical continuity of non-transparent printed conductors in a multiple discharge gas discharge device in which a gas discharge medium is confined between a pair of dielectric coated conductor arrays and selected discharge sites within the gas medium are excited by electrical potentials applied between at least one conductor in one of said arrays and at least one conductor in the other of said arrays, the crossing point of said conductors locating a selected discharge site, comprising printing each conductor of at least one of said arrays on a viewing plate of the device as a set of narrow, spaced apart, conductor elements and making a conductive electrical bridge connection at least at the terminal ends of conductor elements constituting a conductor in the array.
Claim 2
Independent Claim
134 words
A method of increasing efficiency of light transmission and assuring electrical continuity of non-transparent printed conductors in a multiple discharge gas discharge device in which a gas discharge medium is confined between a pair of dielectric coated conductor arrays and selected discharge sites within the gas medium are excited by electrical potentials applied between at least one conductor in one of said arrays and at least one conductor in the other of said arrays, the crossing point of said conductors locating a selected discharge site, comprising printing each conductor of at least one of said arrays on a viewing plate of the device as a set of narrow, spaced apart, conductor elements and making a conductive electrical bridge connection at least at the terminal ends of conductor elements constituting a conductor in the array.
Claim 3
Dependent Claim
24 words

Claim 5
Dependent Claim
26 words
The invention defined in claim 2 wherein said conductive bridges are at regular intervals along the length of the conductive elements of each said pair, respectively.
Claim 6
Dependent Claim
31 words
