Abstract: A plasma display panel and a method thereof is described. A frequency of a sustain pulse varies according to a screen load ratio in each subfield or frame. The frequency of the sustain pulse is determined such that power consumption of the plasma display panel, which is a function of the active power and the reactive power of the sustain pulse, is minimized. When the screen load ratio is increased, the frequency of the sustain pulse is increased since the decrease of the active power is increased and the reactive power is maintained.

Abstract: A plasma display device and a method for driving the plasma display device. Only some row electrodes are addressed in a sub-field having the smallest weight to reduce the luminance of the sub-field having the smallest weight. Only odd-numbered row electrodes are addressed in an odd-numbered frame and only even-numbered row electrodes are addressed in an even-numbered frame in the address period of the sub-field with the smallest weight. The length of the sustain period of a sub-field having the second smallest weight is identical to the length of the sustain period of the sub-field having the smallest weight. Then, the ratio of the luminances of the two sub-fields is increased by twice to improve representation of lower gray scale.

Abstract: A plasma display device of the present invention includes X and Y electrodes applied with a sustain pulse, an M electrode formed between the X and Y electrodes, and an address electrode crossing the X, Y, and M electrodes. For driving such a plasma display device, after applying a reset waveform to the M electrode so as to convert every cell to an on state, an erase scan pulse and an erase address pulse are selectively applied to the M electrode and address electrode so as to convert a cell of an on state to an off state. Subsequently, a sustain pulse is alternately applied to the X and Y electrodes, such that a sustain discharge is generated in cells remaining in the on state and not in cells converted to the off state.

Abstract: A plasma display device and a driving method thereof. For a plasma display device having an M electrode between X and Y electrodes, a sustain pulse is applied to the X and Y electrodes during an entire period, and a reset waveform and a scan pulse are applied to the M electrode. In addition, a scan pulse is applied to the M electrode while applying the sustain pulse to the X or the Y electrode. As a result, a gently decreasing reset waveform may be used so as to enhance contrast. Furthermore, driving circuits for driving the X and Y electrodes may be designed with the same scheme. In addition, an accurate address operation may be achieved.
