CIRCUIT FOR DRIVING PLASMA DISPLAY PANEL AND PLASMA DISPLAY DEVICE

摘要

In a sustain electrode driving circuit (44) for driving a plasma display panel in which a plurality of sustain electrodes (SU1-SU2160) are divided into first and second sustain electrode groups (UG1, UG2), first and second predetermined voltage applying circuits (90a, 90b) apply a first predetermined voltage (Ve2) to first and second electrode paths (RG1, RG2), respectively.  A voltage selecting circuit (100) selects either one of a second predetermined voltage (Vs) or a third predetermined voltage (Ve1) to generate a selected voltage (V3).  First and second sustain pulse generating circuits (80a, 80b) generate a sustain pulse on the basis of the second predetermined voltage (Vs) when the selected voltage (V3) is the second predetermined voltage (Vs), and apply the third predetermined voltage (Ve1) to the first and second electrode paths (RG1, RG2), respectively, when the selected voltage (V3) is the third predetermined voltage (Ve1).
