Abstract: In a plasma display panel whose screen size is made larger and higher definition, a first ramp waveform voltage rising from a potential (Vi1) toward a potential (Vi2) is applied to scanning electrodes (SC1 to SCn) in order to stably generate a writing discharge in the initialization period of at least one subfield (first SF) of one field period. A second ramp waveform voltage is also applied to the scanning electrodes (SC1 to SCn) that allows the waveform voltage to immediately drop when it rises from a base potential toward a predetermined potential (Vers) and reaches the predetermined potential (Vers) at the end of the sustain period of each of the subfields (first SF, second SF, ).

Abstract: 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.

Abstract: PROBLEM TO BE SOLVED: To stably generate a write discharge even in a plasma display panel which has a large screen and high definition. SOLUTION: The plasma display panel generates a first ramped waveform voltage which gently rises in an initialization period of at least one sub-field in one field period, generates a second ramped waveform voltage which has a steeper gradient than the first ramped waveform voltage and which immediately falls once the rising waveform voltage reaches a predetermined potential in the ending of a sustain period, and alternately generates at least two kinds of sustain pulses, i.e. a first sustain pulse which varies from a base potential to a first potential and then falls to the base potential, and a second sustain pulse which varies from the base potential to the first potential and then falls to a second potential and further falls to the base potential in the sustain period. The second sustain pulse is generated right before the second ramped waveform voltage. COPYRIGHT: (C)2009,JPO&INPIT
