Abstract
In a driving method capable of selectively scanning discharge channels in a stable and efficient manner using an open-cell structure, a plasma-addressed display device comprises a display cell, a plasma cell, a scanner, a supply and a controller. The display cell is equipped with data electrodes arranged so as to be mutually parallel. The plasma cell is for creating discharge channels formed in such a manner as to be orthogonal with respect to the data electrodes and has anodes and cathodes alternately arrayed in such a manner as to be shared between adjacent discharge channels. The scanner is for carrying out selective scanning of the discharge channels. The supply is for applying a data voltage to the data electrodes. The controller is for controlling the maximum value of the voltage across the cathodes and anodes, the data electrodes and anodes and the data electrodes and cathodes of each of the discharge channels in such a manner as to not exceed a prescribed plasma discharge start voltage at periods other than periods of plasma discharge.
