A DRIVING APPARATUS OF PLASMA PANEL, A METHOD FOR DISPLAYING PICTURES ON PLASMA DISPLAY PANEL AND A PLASMA DISPLAY PANEL

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a driving apparatus of a plasma display panel and an image processing method of a plasma display panel which compensate for a decrease in luminance due to long use. First, the operation time of the plasma display panel is accumulated and measured. If the measured cumulative time is less than or equal to a predetermined reference level, that is, if the luminance reduction rate is less than or equal to a certain reference level, the number of subfields is reduced. At this time, it is allocated to increase the number of sustains of subfields used corresponding to the reduced subfields. Through this, it is possible to compensate for the decrease in luminance that may occur due to long-term use of the plasma display panel. In addition, the lifespan of the plasma display panel can be further increased by compensating for the decrease in luminance.;PDP, Luminance, Subfield, Sustain
