Abstract

본 발명은 개선된 피디피(PDP) 디스플레이 장치의 밝기 조절장치에 관한 것으로, 외부로부터의 조작신호에 기초한 조절스위치로부터의 조절신호에 의거하여 벽전하의 전압레벨이 전압조절부를 통해 V₁+ dV 범위 내에서 조절되고, 서스테인 구간에 펄스발생부로부터 제공되는 스위칭신호에 의거하여 스위칭부를 통해 전압조절부에서 조절된 벽전하의 전압이 고전압 발생부로 제공되며, 고전압 발생부에서 그에 상응하는 고전압이 발생되어 PDP를 구성하고 있는 각 단위셀의 서스테인용 전극으로 제공되므로써, 외부로부터의 조작신호에 의거하여 PDP를 구성하고 있는 각 단위셀의 서스테인용 전극으로 제공되는 벽전하 전압레벨을 조절할 수 있으므로, 그에 따라 PDP의 밝기를 조절할 수 있도록 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brightness control device of an improved PDP display device, wherein a voltage level of wall charge is in the range of V ₁ + dV based on a control signal from a control switch based on an operation signal from the outside. Based on the switching signal provided from the pulse generator in the sustain period, the voltage of the wall charges regulated by the voltage regulator is provided to the high voltage generator, and the corresponding high voltage is generated in the high voltage generator. By providing the sustain electrode of each unit cell constituting the PDP, the wall charge voltage level provided to the sustain electrode of each unit cell constituting the PDP can be adjusted accordingly. The brightness of the PDP can be adjusted.
