Abstract A planar plasma discharge panel comprises a first group of electrical conductors secured to an electrically non-conducting substrate. A layer of electrically non-conducting dielectric material is secured to said substrate and to said conductors to form an electrically non-conductive surface thereover. A second group of electrical conductors is secured to said surface. The conductors of the second group cross the conductors of the first group at an angle so that the crossover areas of said conductors define discharge points of the plasma display panel. A second layer of electrically non-conductive dielectric material is secured to the first surface layer and to the second group of electrical conductors. An appropriate ionizable gas medium is confined above this second layer of dielectric material. The discharge pattern generated by the device is from point to point on the dielectric surface of the second layer of electrically non-conductive material with the desired electrical fields being generated by the underlying grid of conductors. The gaseous medium is selected for the desired discharge characteristics of the panel. Several embodiments are shown for controlling the discharge so as to improve panel resolution.

A plasma discharge display panel comprising: an electrically non-conductiNg substrate, said substrate being contoured to have a plurality of parallel channels therein; a first group of electrical conductors secured to said substrate in orthogonal relationship to said channels and conformed to the contour thereof and in generally parallel relation to one another and, further, said conductors being adapted to be connected with a source of drive voltage for the panel; a first layer of electrically non-conducting dielectric material secured to said substrate in overlying relation to said electrical conductors to form an electrically non-conducting generally planar surface; a second group of electrical conductors secured to said surface, each of said conductors in generally overlying relation to one of said channels, so that the conductors of said second group are in crossing relation to the conductors of said first group, said substrate having at least one shoulder for each conductor of said first group in relation to each of said channels to define discharge areas on said panel between said shoulders of said conductors of the first group and related conductors of said second group, the conductors of said second group being adapted to be connected with a source of drive voltage for the panel; a second layer of electrically non-conducting dielectric material secured to said first layer in overlying relation to said second group of electrical conductors forming an electrically non-conducting surface; and, means for confining an ionizable gaseous atmosphere over said second layer of dielectric material.
Claim 3
Dependent Claim
61 words
The structure of claim 1 wherein each of said second conductors is displaced in overlaying longitudinal relationship to said channels, the displacement being sufficiently to one side of each of said channels so that the discharge area on the surface of said panel only occurs between one shoulder of each of said first conductors and associated ones of said second conductors.
