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.

摘要： A method for driving a display panel with which the dark contrast can be improved is provided. Each of at least two successive sub-fields including a leading sub-field includes a selective write addressing step for setting the discharge cells to a lighted discharge cell mode by selectively causing a writing discharge in the discharge cells in accordance with the video signal. The sub-fields following at least two sub-fields include a selective erasure addressing step for setting the discharge cells to an unlighted discharge cell mode by selectively causing an erasing discharge in the discharge cells in accordance with the video signal and an emission sustain step for repeatedly causing a sustain discharge corresponding to a weighting of that sub-field only in the discharge cells that are in the lighted discharge cell mode. The last sub-field of each field includes a first erasing step for inducing a first erasing discharge between the column electrode and one of the row electrodes of the row electrode pair belonging to the discharge cells that have been set to the unlighted discharge cell mode in the selective erasure addressing step and a second erasing step for inducing a second erasing discharge between the row electrodes of the row electrode pair belonging to the discharge cells that have been set to the lighted discharge cell mode in the selective write addressing step, the first erasing step and the second erasing step being performed immediately after the emission sustain step.
