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 method of driving a plasma display panel for improving the contrast at low power consumption while suppressing spurious borders, and for stabilizing selective discharge to improve the display quality. The method selects either a first mode in which the number of times of light emission in a light emission sustaining stage in each subfield (SF) within a SF group in one field display period is set to a first value, or a second mode in which the number of times of light emission in the light emission sustaining stage in each SF within the SF group is set to a second value lower than the first value. When the second mode is selected, at least one of the values of a pulse width and a pulse voltage of a scanning pulse in each SF within the SF group is set larger than the corresponding value of the pulse width or the pulse voltage of the scanning pulse in each SF within the SF group when the first mode is selected.

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.
