摘要： A method for driving a plasma display panel is deviced to produce a high-quality image with an increased number of gradations. In each subfield, first and second picture element data write processes are executed for writing picture element data in each discharge cell belonging to first and second display areas of the plasma display panel. In addition, first and second light emission sustaining processes are executed for emitting discharge cells in the light emitting state out of the discharge cells belonging to the first and second display areas. In this process, in subfields with less weight among the subfields, the first light emission sustaining process is executed immediately after the completion of the first picture element data write process, the second picture element data write process is executed immediately after the completion of the first light emission sustaining process, and the second light emission sustaining process is executed immediately after the completion of the second picture element data write process.

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 driving apparatus of a plasma display panel performs allows image display in a desired way. When discharge cells are driven to repetitively execute a sustain-discharge by the application of sustaining pulses to row electrodes the number of times corresponding to subfields, a ratio of changes of a voltage value in a trailing interval of the last sustaining pulse among those sustaining pulses is set to be milder than that of a voltage value in a trailing interval of the sustaining pulse which is applied just before the last sustaining pulse. Further, description has been made for a driving method of a plasma display panel which can perform an image display of high quality by performing a proper selective discharge while preventing an erroneous discharge of the discharge cells in a pixel data writing step. A trailing edge portion of the sustaining pulse which is applied finally among the sustaining pulses applied in a light emission sustaining step has an undershoot part below a ground potential.
