Plasma display device and driving method of plasma display panel
Abstract:
A stable address discharge is generated and number of unlit cells is decreased without heightening the voltage necessary for generating an address discharge. For this purpose, the device includes a plasma display panel and a driving circuit for driving the plasma display panel, in which the driving circuit drives the plasma display panel having a sub-field group formed of two or more continuous sub-fields for controlling addressing provided in one field period, so as not to generate sustain discharge in the discharge cell not causing sustain discharge and also in the subsequent sub-fields, the discharge cell is initialized by applying a ramp waveform voltage descending gently to the scan electrode, the lowest voltage of the ramp waveform voltage of the sub-field included in the sub-field group is made different from the lowest voltage of the ramp waveform voltage of the sub-field not included in the sub-field group.
