A plasma display apparatus, and more particularly, a driving method and improved structure of a plasma display apparatus are provided. A sustain signal that alternates between a positive polarity and a negative polarity is supplied to only one electrode. Therefore, it can facilitate the adoption of an integrated driving board. Furthermore, a voltage magnitude of a set-up signal supplying in any one of the remaining sub-fields other than a first sub-field of a frame is less than the voltage magnitude of the set-up signal supplying in the first sub-field. It is therefore possible to increase the contrast.

Plasma display apparatus and driving method thereof

A plasma display apparatus and a method of driving the same are disclosed. The plasma display apparatus includes a driver supplying a first signal and a second signal to a scan electrode during a reset period of at least one of a plurality of subfields of a frame. The first signal gradually rises from a first voltage to a second voltage with a first slope, and then falls from the second voltage to a third voltage with a second slope. The second signal rises from the third voltage to a fourth voltage, and then gradually rises from the fourth voltage to a fifth voltage with a third slope.

Plasma display apparatus and method of driving the same

A plasma display panel for adaptively reducing load effect and improving luminescence efficiency and discharge efficiency, and a driving method thereof. A plasma display panel includes a capacitive load; a source capacitor; a sustain voltage source to generate a sustain voltage; a first inductor formed on a first current path where a current flows from the capacitive load to the source capacitor; a second inductor formed on a second current path where a current flows from the source capacitor to the capacitive load; a switch configuration and switch control circuit that controls the switching operations of the switch configuration such that at least two discharges may occur during one sustain pulse cycle.

Plasma display and driving method thereof

The present invention relates to a plasma display apparatus, and more particularly, to a plasma display apparatus for preventing Electromagnetic Interference (EMI). The plasma display apparatus of the present invention comprises a plasma display panel comprising an electrode, and at least one of a first capacitor connected between a sustain voltage source for supplying a sustain voltage to the electrodes and a first ground voltage source, a second capacitor connected between a scan voltage source for supplying a scan voltage to the electrodes and a second ground voltage source, and a third capacitor connected between a set-up voltage source for supplying a set-up voltage to the electrodes and a third ground voltage source.
