- 16 - AC PLASMA PANEL Abstract There is disclosed an ac plasma panel having gray tone and color control. The plasma panel is constructed using a matrix of discharge sites, each site associated with one or more migration sites. The migration sites, in turn, have different color light producing phosphor coatings on electrical field controlling conductors. During the ionization of the plasma gas at the discharge sites, a selective electrical field is established between a discharge site and an adjacent migration site thereby attracting electrons to excite the phosphor coatings. The selection of the different migration sites controls the color produced by the panel, and the amplitude of the selective electrical field controls the light intensity.
