摘要： A plasma display and a driving device therefor. In a sustain discharge driving circuit that includes a power recovery circuit and a sustain voltage supply circuit, a transformer is used. The transformer includes a primary coil and a secondary coil that are coupled with each other. The primary coil of the transformer is connected in parallel to a panel capacitor serving as a capacitive load so as to increase a change of a voltage that is applied to an inductor, such that a voltage rising period and a voltage falling period are reduced. With the reduction of the turn-on time of a switch, the power consumption of the switch is reduced. Further, as the inductor initially stores current, the occurrence of hard switching is reduced when a sustain discharge voltage is applied and elements of the circuit are protected.

摘要： 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.

摘要： 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.

摘要： A plasma display and driving method thereof. A median electrode is formed between X and Y electrodes for receiving sustain pulse voltages, and a reset waveform and a scan pulse voltage are applied to the median electrode. A short gap discharge is performed between the X electrode and the median electrode during the initial interval of a sustain interval, and a long gap discharge is performed between the X and Y electrodes during the normal sustain interval to thus perform a stable discharge. The X and Y electrode drivers are realized through comparable circuits since the waveforms applied to the X and Y electrodes are substantially symmetric.
