摘要： A plasma display device includes: a sustain drive unit that applies a sustain pulse having a first voltage and a second voltage lower than the first voltage to a plurality of first electrodes; a scan drive unit including a plurality of selection circuits coupled to the first electrodes and each including first and second switches; and a clamping unit including a clamping diode coupled to at least one of the selection circuits and clamps the voltage of the first electrode at the first voltage when it exceeds the first voltage. The plasma display device can prevent overshoot that can occur when the first voltage of the sustain pulse is applied to the first electrode in a sustain period so as to apply a stable discharge pulse. The magnitude of the overshoot may depend on the distance between the scan driving board and each of the plurality of selection circuits IC.

摘要： In a plasma display device, a capacitor is coupled between the high voltage terminal and the low voltage terminal of a scan circuit. During a first period of a falling period of a reset period, voltage of a scan electrode is gradually decreased to a first voltage through the low voltage terminal and the capacitor. Next, during a second period of the falling period, the voltage of the scan electrode is gradually decreased from the first voltage to a second voltage through the low voltage terminal without through the capacitor.

摘要： A plasma display including a first electrode and a second electrode formed in parallel is disclosed. The plasma display gradually decreases a voltage at the second electrode from a second voltage to a third voltage while a first voltage is applied to the first electrode during a reset period. The plasma display changes the first voltage according to a change in the discharge firing voltage between the first electrode and the second electrode. The change in the discharge firing voltage may be determined in accordance with an accumulated driving time or a discharge time during the reset period.
