Abstract
A plasma display panel has twin X and twin Y orthogonal drive lines in place of the single X and single Y drive lines of prior art panels. Each pair of twin drive lines are in close proximity and spaced a relatively much greater distance from the next pair. The dielectric layer covering the drive lines is sufficiently thick to cause the voltage potentials on the twin drive lines to image as one potential on the surface of the dielectric. Each one of the twin drive lines is connected to a selection line such that the raising of any two X selection lines and two Y selection lines produces a write-erase potential on a particular gas cell.
