Abstract
In order to provide a method for driving a display panel capable of improving durability of a driving device for driving a display panel, when a scan pulse is applied in superposition with a base pulse to one of row electrodes of one row electrode pair among row electrode pairs while the base pulse is applied to one of the row electrodes of all the row electrode pairs in the display panel and a pixel data pulse corresponding to an image signal is applied to the row electrode at the same timing as that of the scan pulse to set discharge cells to either one of a light-on mode and a light-off mode, a change ratio of a voltage value in a fall period in the base pulse is smaller than a change ratio of a voltage value in a fall period in the scan pulse.
