Abstract
Abstract This is a system for connecting flexible electrical connectors having raised conductors above an insulating substrate to a plasma display panel having a glass substrate with the electrical conductors deposited in the bottom surface of conductor pathways etched in a glass substrate. The raised conductors on the connectors mate with the depressed conductors in the panel substrate. The spacing of the conductors in the connector may be varied to facilitate an exact mating with the conductors in the panel substrate. A clip device in combination with a flexible insulating force spreading member applies a uniform continuous pressure to the connector cable and glass substrate combination to maintain connection. This system may be used to facilitate the direct attachment of large scale integrated circuit chip carriers having conductor members on a surface thereof directly to conductors in a plasma display panel substrate.

Claim 1
Independent Claim
327 words
In combination, a gas discharge display panel having a pair of glass substrates assembled to form a thin gas discharge display chamber, wherein each of said substrates has a plurality of electrical conductors extending in a parallel fashion and said substrates are assembled with said conductors in an orthogonal relationship to define gas discharge display areas and each substrate has conductor connection means extending from the discharge display chamber at edges thereof consisting of depressed conductor pathways etched in the substrate having the conductor element deposited in the bottom thereof at a location exterior to the discharge display chamber, said conductors typically spaced apart 0.8 mm and 0.2 mm in width, and wherein said exterior conductors are electrically and physically continuous extensions of said conductors defining the gas discharge display areas, and a system for the connection of said gas plasma display panel to electrical signals which comprises: a conductor means having multiple conductors supported by an insulating medium and terminating in raised conductor elements which correspond in spacing to the spacing of the depressed conductors on said substrate, for carrying electrical signals; clip members having a U-shaped portion with clip contact areas on the inside of the legs of the U-shaped portion and with a pair of flanges, one at the end of each leg of the U-shaped portion, each flange having an engaging portion parallel to and spaced apart from the associated leg of the U-shaped portion and a connecting portion for connecting said mating portion to the leg of said U-shaped portion, said flanges adapted for engaging with a spreading tool at said engaging portion thereof, for securing said conductor means in position by the application of spring forces on said conductor means and on said substrates, and flexible force spreading means placed between said clip contact areas and said conductor means and said substrate to spread the force of application of said clip on connecting conductors from said conductor means and said panel.
