Abstract

The present invention relates to a priming method in the cells of a plasma display panel and a device implementing said method. In a plasma display panel, each cell is provided with at least two electrodes and one type of phosphor out of at least two types is associated with each of the cells to determine the color of the light emitted by the cell. Priming consists in applying a voltage greater than a threshold voltage between the electrodes of the cells. Since the threshold voltage above which electrical charges are created in the cell is different according to the type of phosphor of the cell, it is proposed according to the invention to use, to create the charges in the cells, a voltage that differs according to the type of phosphor so as to create only the electrical charges needed in the cells.
