ABSTRACT:
A high-definition large-screen panel capable of realizing full-color high-luminance display without the restrictions that have been imposed on luminance (number of sustaining discharges) and gray-scale display or the number of display lines in the past has been disclosed. The panel includes a plurality of cells that selectively discharge to glow. According to a driving method for a plasma display panel, during an addressing period, a voltage is applied selectively to cells according to display data so that a charge proportional to display data can be stored in each cell. During a sustaining discharge period, a sustaining discharge voltage is applied to the plurality of cells so that cells in which given charges are stored can discharge to glow. In the driving method, during the addressing period, a plurality of different voltages associated with gray-scale levels to be displayed are applied to the cells so that a quantity of charge proportional to an applied voltage can be stored in each cell. During the sustaining discharge period, the strength of an applied voltage is varied.
