Abstract

본 발명은 피디피(PDP) 디스플레이 장치의 휘도 보정방법에 관한 것으로, 동기분리부를 통해 분리된 Vsync에 기초한 펄스발생부로부터의 서스테인을 위한 타이밍 펄스에 의거하여 서스테인부와 스캔 및 서스테인부를 통해 복수개의 수평라인(L₁, L₂, L₃,..., L_2N) 중에 두개의 수평라인에 대해 Ⅰ가 각각 수행되고, 펄스발생부로부터의 두개의 수평라인을 스캔하기 위한 타이밍 펄스에 의거하여 스캔 및 서스테인부를 통해 복수개의 수평라인 중에 두개의 수평라인이 동시에 스캔되며, 펄스 발생부로부터의 서스테인을 위한 타이밍펄스에 의거하여 서스테인부와 스캔 및 서스테인부를 통해 하나의 서브필드에 대한 모든 수평라인이 전면적으로 서스테인되므로써, 동시에 복수개의 수평라인을 스캔하여 스캔시간을 줄일 수 있으므로, 선택된 단위셀에 생성된 벽전하가 약해지거나 소멸되므로써 발생되는 각 수평라인 간의 휘도차이를 보정할 수 있도록 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a luminance correction method of a PDP display device, and includes a plurality of horizontal lines through a sustain unit, a scan unit, and a sustain unit based on timing pulses for sustaining the pulse generator based on the Vsync separated through the sync separator. I is performed on two horizontal lines, respectively, among the lines L ₁ , L ₂ , L ₃ , ..., L _2N , and is scanned based on a timing pulse for scanning the two horizontal lines from the pulse generator. And two horizontal lines of the plurality of horizontal lines are simultaneously scanned through the sustain unit, and all horizontal lines for one subfield are sustained through the sustain unit and the scan and sustain units based on timing pulses for sustaining from the pulse generator. As a result, the scan time can be reduced by scanning multiple horizontal lines at the same time. Is one to correct the brightness difference between the horizontal line in which the wall charges generated weakened or destroyed doemeurosseo.
