Abstract
A plasma addressing structure functioning as a display panel (52) includes an ionizable gas captured within a network (110) of intersecting channels formed by multiple spaced-apart islands (60) arranged in substantially parallel rows (62) projecting from the major surface (104) of an underlying substrate (64). The network of channels includes elongated channels (112) that are positioned between adjacent rows of islands, and spur channels (114) that extend between individual islands in each row and couple adjacent elongated channels. The gas in the network of channels is selectively ionized to address display elements (54), which are aligned with the islands positioned along each of the island rows. Each island has a top surface or plateau (128) that is spaced-apart from and substantially parallel to the major surface from which the island projects. The plateaus provide a relatively large surface area for supporting addressing structure components such as a layer (68) of electro-optic material and a layer (96) of dielectric material.
