Abstract

A method of driving a plasma display device that includes a plurality of scanning electrodes, a plurality of sustaining electrodes, and a plurality of data electrodes is such that, when m is any given integer, the data electrodes are applied with a negative polarity pulse when a voltage applied to the scanning electrodes gradually decreases during the initialization period, if a final pulse in a sustain period of an (m-1)-th subfield is applied to the scanning electrodes and an m-th subfield includes an initialization period. If the final pulse in the sustain period of the (m-1)-th subfield is applied to the sustaining electrodes and the m-th subfield includes the initialization period, the data electrodes are applied with a positive polarity pulse when a voltage applied to the scanning electrodes gradually increases during the initialization period.

Description

technical field

[0001] The invention relates to a plasma display screen display device and its driving method, in particular to an improved technology for reducing power consumption during driving. Background technique

[0002] Plasma display (hereinafter referred to as "PDP") excites phosphor powder to emit light through ultraviolet rays generated in gas discharge to display images. According to the type of discharge method, it is divided into alternating current (AC) type and direct current (DC) type. The AC type is characterized by being superior to the DC type in terms of brightness, luminous efficiency, and lifetime. Among the AC types, the reflective surface discharge type is particularly excellent in brightness and luminous efficiency, and the reflective surface discharge type is the most commonly used.

[0003] Figure 9 It is a perspective view schematically showing the conventional AC type PDP unit 10 . Such as Figure 9 As shown, in the structure of the PDP uni...
