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 phosphor areas in conjunction with an electrical field controlling conductor. During the ionization of the plasma gas a selective electrical field is established between a discharge site and an adjacent migration site and the electrons from the gas ionization are free to migrate to the phosphor area of the screen in accordance with the magnitude of the electrical signals on the control conductor.
