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: A technology effective for improving the luminous efficiency, lifetime, and color temperature of a PDP having phosphor layers of three colors is disclosed. A PDP comprises a plurality of narrow tubes (60) arrayed on a substrate (51). In each narrow tube (60), one of phosphor layers (61R, 61B, 61G) is formed and a discharge gas is contained. The compositions and pressures of the discharge gases are set within appropriate ranges respectively corresponding to the phosphor layers (61R, 61B, 61G). Consequently, the PDP can have a lengthened life-time and an improved luminous efficiency. Reductions of variation in breakdown voltage and adjustment of color temperature are also possible with this constitution.

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.
