Plasma Display Panel Drive Method And Plasma Display Device
One field period is structured of a plurality of subfields (SF), each including an initializing period, writing period, and sustaining period. Performed in the initializing period of each SF is all-cell initializing operation for generating initializing discharge in all the discharge cells to be used for image display, or selective initializing operation for generating initializing discharge in the discharge cells having generated sustaining discharge in the preceding SF. The period allocated to the writing discharge in a SF for the all-cell initializing operation is set shorter than the period allocated to the writing discharge in a SF for the selective initializing operation. This structure provides a plasma display panel driving method and a plasma display device capable of inhibiting increases in black picture level and displaying images at excellent quality.
1 . A plasma display panel driving method, in which one field period comprises a plurality of subfields (SFs), each of the SFs including an initializing period for generating initialing discharge in discharge cells, a writing period for generating writing discharge in the discharge cells, and a sustaining period for generating sustaining discharge to cause the discharge cells to emit light at a predetermined brightness weight; the initializing discharge includes all-cell initializing operation for causing initializing operation in all the discharge cells to be used to display an image, and selective initializing operation for selectively causing initializing operation in the discharge cells having generated sustaining discharge in a preceding one of the SFs thereof, and a period allocated to the writing discharge in one of the SFs for performing the all-cell initializing operation is set shorter than a period allocated to the writing discharge in another one of the SFs for performing the selective initializing operation; and each of the discharge cells is formed at an intersection of scan and sustain electrodes and a data electrode, the method comprising:
determining to cause one of the all-cell initializing operation and the selective initializing operation in the initializing period in each of the plurality of SFs.
