摘要： In conventional plasma display devices, reset by obtuse waves has been performed since discharge intensity becomes higher and background light emission is increased when reset by rectangular waves is performed. However, further improvement of the contrast to improve the image quality has been demanded. The present invention provides a driving method of a plasma display device using obtuse-wave reset in which sustain time of an achieved potential of the obtuse-wave reset is controlled in accordance with a display ratio of a video signal.

摘要： A capacitive load drive circuit that has reduced power consumption due to residual carriers, and a PDP apparatus using the same, have been disclosed. In the drive circuit, the power consumption due to the residual carriers, which are formed when a diode provided in parallel to a switch circuit of the capacitive load drive circuit is brought into conduction, is reduced and the switch circuit connected in parallel to the diode is brought into conduction during a period of time from when the diode is brought into conduction until when the potential of a terminal to which the diode is connected changes. By bringing the switch circuit connected in parallel into conduction, a closed circuit is formed by the diode and the switch circuit and the residual carriers formed in the diode are reduced. The voltage of the closed circuit is substantially zero V and, therefore, power consumption is very small even if a current due to the residual carriers flows through the closed circuit.
