ABSTRACT:
A plasma addressing structure (52) having an ionizable gas captured within each of multiple parallel channels (62a) extending across a display screen (54) includes an arrangement (132a) of anodes (112a) and cathodes (114a) for selectively ionizing the gas to address data elements. The anode in each channel has an extended width (130a) in a direction transverse to the length of the channel, thereby to provide the channel with a relatively large conductive surface area that facilitates the ionization of the gas contained in the channel. The large conductive surface provided by the extended width of the anode allows each channel to be formed with a shallow depth (118a) that enhances the viewing angle characteristics of the display screen and simplifies the manufacture of the addressing structure.
