摘要： A plurality of subfields of a field period includes a subfield for performing an every-cell initialization causing an initial discharge in every discharge cell in an initialization period, and includes a subfield for performing a selective initialization causing the initial discharge in a predetermined discharge cell in the initialization period. In a low-luminance subfield, the every-cell initialization is performed, and a low-luminance subfield is subsequently located (in the field period) to the subfield for the every-cell initialization. In a sustain period of the subfield for performing the every-cell initialization or a sustain period of the low-luminance subfield, a width of a first sustain pulse is set wider than a width of a second sustain pulse, and the width of the second sustain pulse is set wider than the width of a third sustain pulse and subsequent others.

摘要： Provided to stabilize generation of address discharge and improve gradation characteristics of display images are the following elements: a plasma display panel; a sustain pulse generating circuit; and a ramp voltage generating circuit including a first ramp voltage generating circuit, a second ramp voltage generating circuit, and a switching circuit. The first ramp voltage generating circuit generates a first ramp voltage gently increasing in an initializing period. The second ramp voltage generating circuit generates a second ramp voltage increasing with a gradient gentler than that of the rising edge of a sustain pulse and steeper than that of the first ramp voltage, at the end of each sustain period. The switching circuit stops the operation of the second ramp voltage generating circuit immediately after the second ramp voltage reaches a predetermined electric potential. In at least one sustain period of one field, no sustain pulse but the second ramp voltage is generated.

摘要： The method for driving a plasma display panel effects control of the subfields as follows. The all-cell initializing operation on the discharge cell is carried out in the initializing period of at least one sub-filed; the rest of the subfields other than the aforementioned subfield selectively carry out an addressing operation in each discharge cell. Gradation display is attained by combination of a subfield having an address discharge in the address period and a sub-filed with no address discharge in the address period. In a discharge cell where an address discharge is generated in the address period of a subfield that follows the subfield having the all-cell initializing operation in the initializing period, the subfield having the all-cell initializing operation has an address period for generating an address discharge.

摘要： In a driving method of a panel, one field period is formed by arranging a plurality of subfields that have an address period for selectively causing address discharge in a discharge cell, and a sustain period for causing as many sustain discharges as the number corresponding to luminance weight in the discharge cell. One field period is formed by arranging a plurality of subfield groups having a plurality of subfields whose luminance weights monotonically increase. In the discharge cell for causing address discharge in a certain subfield other than the head subfield in each subfield group, address discharge is caused even in the head subfield.
