Abstract
Abstract A display panel includes a base plate and face plate having internal electrodes connected to contact pads disposed along an edge of the panel. The base plate and face plate are spaced apart along said edge of the panel so that flexible terminals or pins can be inserted therebetween to make contact with the contact pads and to connect the internal panel electrodes to external circuitry. The panel includes means for mechanically supporting all of the leads and for cementing the leads to the support member, thus providing a rigid lead assembly which can be handled with ease by a user.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
160 words
A display panel comprising a gas-filled envelope including a base plate and face plate hermetically sealed together by a seal to form said envelope, with portions of said base plate and face plate extending beyond said seal to define one edge of said panel, a plurality of electrodes within said envelope and conductive runs extending from said electrodes through said seal to the exterior of said envelope where they terminate in contact pads, said contact pads being disposed outside said envelope on said portions of said base plate and face plate, an auxiliary member secured to the edge of one of said plates and extending along said edge of said panel to provide a support surface, said support surface being of insulating material, a flexible terminal in electrical contact with each contact pad and seated on said auxiliary member as a support surface, and an insulating cement securing said terminals to said support surface to form a rigid assembly thereof.
Claim 2
Dependent Claim
160 words
A display panel comprising a gas-filled envelope including a base plate and face plate hermetically sealed together by a seal to form said envelope, with portions of said base plate and face plate extending beyond said seal to define one edge of said panel, a plurality of electrodes within said envelope and conductive runs extending from said electrodes through said seal to the exterior of said envelope where they terminate in contact pads, said contact pads being disposed outside said envelope on said portions of said base plate and face plate, an auxiliary member secured to the edge of one of said plates and extending along said edge of said panel to provide a support surface, said support surface being of insulating material, a flexible terminal in electrical contact with each contact pad and seated on said auxiliary member as a support surface, and an insulating cement securing said terminals to said support surface to form a rigid assembly thereof.
Claim 3
Dependent Claim
29 words
The panel defined in claim 1 wherein said base plate and face plate are hermetically sealed together by a sealing ring disposed between said base plate and face plate.
Claim 4
Dependent Claim
45 words
The panel defined in claim 1 wherein both said base plate and face plate extend beyond said seal outside said envelope, and said auxiliary member is an insulating rod secured to one of said plates, and said cement secures said terminals to said insulating rod.
Claim 5
Dependent Claim
56 words
The panel defined in claim 1 wherein adjacent portions of said base plate and face plate extend beyond said seal, said adjacent portions being spaced apart to provide a space between them, said contact pads being disposed along said adjacent portions, and said terminals being positioned in the space between said base plate and face plate.
Claim 6
Dependent Claim
