Abstract
A PDP driving method, in which a stable writing discharge can be realized by using a scanning pulse whose width is narrow without changing a structure of the panel and an image having high light emitting luminance can be realized in the large number of scanning lines, is provided. When a scanning pulse is applied to scanning electrodes, a writing discharge is generated at all of display cells. Electric charge particles generated by the writing discharge at the display cells are supplied to display cells on the next scanning line by diffusion. The writing discharge is stably generated in high speed at the next scanning line when a scanning pulse is applied to the next scanning line by receiving the electric charge particles, consequently, the width of the scanning pulse can be made to be narrow. In order that the writing discharge is generated at display cells, which do not shift to a sustaining discharge, a sub scanning pulse being negative polarity is applied to common electrodes.
