摘要： A method for driving a plasma display panel (PDP) that can increase dark contrast without causing erroneous discharges is provided. A unit display period is divided into a plurality of subfields. A reset process and a sustain process are performed in one of the subfields. In the reset process, a reset pulse is applied to row electrodes of the PDP to initialize each discharge cell to an emission mode (or non-emission mode). In the sustain process, a sustain discharge is repeatedly generated a number of times, corresponding to the number of times a sustain pulse is to be applied, in those discharge cells that are in the emission mode. In this case, a peak potential of the reset pulse is changed based on the number of those discharge cells that are maintained in the non-emission mode during the unit display period and the number of times the sustain pulse is to be applied in the sustain process in this subfield.

摘要： A display panel includes a plurality of unit light emission areas (light emission elements) arranged in a matrix. Each unit light emission area is defined by a first discharge cell and a second discharge cell. The second discharge cell has a light-absorbing layer. When the display panel is driven to express an image having a plurality of gradation levels, address discharge is selectively caused in the second discharge cells in accordance with an input image signal. Light leaks to the first discharge cell from the second discharge cell upon the address discharge. This light is used to express the gradation of low luminance. Since luminance difference between gradation levels of a low luminance image is reduced, it is possible to display a high quality, low luminance image.

摘要： A display and a driving method of a display panel capable of improving a dark contrast. In driving the display panel having light-emission areas formed at each intersection of a plurality of pairs of row electrodes and a plurality of column electrodes, each of the light-emission areas having a first discharge cell including a portion where the respective row electrodes in pair are opposed to each other with a predetermined discharge gap within a discharge space and a second discharge cell including a portion where a light absorptive layer is provided and one row electrode of the row electrode pair and the other row electrode of the row electrode pair adjacent to this row electrode pair are opposed to each other with a predetermined discharge gap, an address discharge is produced within the second discharge cell, to set the second discharge cell at a light-on state or a light-off state, by applying a pixel data pulse based on an input image signal, to respective column electrodes, while applying a scanning pulse to a row electrode having the longer distance to the first discharge cell, of the respective row electrodes within the second discharge cell. This structure causes the address discharge within the second discharge cell relatively distant from the first discharge cell, so that the amount of a ultraviolet ray by the address discharge flowing into the first discharge cell is reduced, to suppress the deterioration of the dark contrast.
